—Kyphosis and lordosis changes might be related to back extensor weakness and osteoporosis. The purpose of this study was to find out the correlations between thoracic kyphosis, lumbar lordosis with back extensor strength (BES) and bone mineral density (BMD). Methods: Thoracic kyphosis, lumbar lordosis, maximal isometric strength of the back extensors and BMD of the lumbar vertebral were evaluated in 47 elderly (50-75 years old)women. BMD of the lumbar vertebral was measured using Dual-Energy X-Ray Absorptiometry (DEXA) and kyphosis and lordosis degree were assayed using a flexible ruler. The maximal isometric strength of the back extensors was measured using an isometric manual muscle tester (MMT). Data were analyzed using ANOVA and independent t-test at p≤0.05 level of acceptance. Results: A significant reverse correlation was shown between BES and kyphosis (p=0.044, r=-0.30). No significant correlation were found between BES and lordosis degree, nor between lumbar vertebral BMD and, both, kyphosis and lordosis degrees. However, there was a significant difference in BES between three groups with various degree of kyphosis (p≤ 0.05). Conclusion: It can be concluded that the severity of thoracic kyphosis may be influenced by BES. So, stronger back extensor can prevent thoracic kyphosis despite decreased BMD.
This randomized controlled trial examined the effects of two modified posterior shoulder stretching exercises (PSSEs) on shoulder mobility, pain, and dysfunction in patients with subacromial impingement syndrome (SIS). 67 patients with SIS and internal rotation deficit were assigned to receive either a modified cross-body stretch, modified sleeper stretch, or a control treatment of modalities and exercises without PSSEs. Both stretching groups demonstrated greater improvements in pain with activity, internal rotation range of motion, function, and disability compared to the control group. However, there was no significant difference between the two stretching groups. All treatments led to improvements in pain, shoulder mobility, function, and disability.
Assessing the Relationship between Body Composition and Spinal Curvatures in ...peertechzpublication
This study investigated the relationship between body composition and spinal curvatures in young adults. Body composition analysis was performed on 67 participants to determine ratios of total fat, body fat, visceral fat, and total muscle. Spinal curvatures of the thoracic and lumbar regions were also measured. The results showed a significant positive correlation between total fat ratio and lumbar lordosis, as well as between visceral fat ratio and lumbar lordosis. Thoracic kyphosis was positively correlated with total fat ratio and visceral fat ratio. Total muscle ratio showed a negative correlation with lumbar lordosis and thoracic kyphosis. The study suggests that increased fat ratios and decreased muscle ratios can shift spinal alignment in a way that may negatively impact
Assessment of the Muscle Strength and Range of
Motion Ankle in Boys With and Without Flatfoot by Kasbparast Mehdi in Research & Investigations in Sports Medicine
This document provides background information and literature review for a study comparing the effectiveness of kinesio taping and exercise for shoulder impingement syndrome. It introduces shoulder impingement as a common shoulder problem caused by inadequate space for rotator cuff tendons. The literature review summarizes previous studies that found scapular taping, therapeutic kinesio taping, and exercise programs can reduce pain and improve function in impingement. Outcome measures to be used in the proposed study include VAS (visual analog scale) for pain, DASH scale for function assessment, and goniometry for range of motion measurements.
This study examined the effects of whole body vibration (WBV) exercise on muscle strength and proprioception in females with knee osteoarthritis. Fifty-two female patients were randomly assigned to one of three groups: 1) WBV exercise on a balance board, 2) WBV exercise on a stable platform, or 3) a non-exercise control group. The WBV groups underwent twice weekly sessions for 8 weeks that progressively increased in intensity. The study found that muscle strength significantly increased in the stable platform group compared to the control group. Proprioception significantly improved in the balance board group compared to the control group. WBV exercise provided benefits to muscle strength and proprioception in females with knee osteoarthritis.
Correlation between conventional clinical tests and a new movement assessment...Stavros Litsos
Correlation between conventional clinical tests and a new movement assessment battery - Bachelor thesis
Despite the complexity of movements performed in sports, physical examination is today done by conventional tests that evaluate joints and muscles individually (e.g. Smith press test, Figure1). Our study used a new movement assessment battery of 20 reach tests, which incorporates the complexity and diversity of natural human movements, taking into consideration that joints are interdependent in a movement and that the planes and sequences of a movement change during its performance. The purpose of this study was to determine whether or not there is a correlation between conventional mobility tests and the new assessment battery.
This study examined core stability measures in male and female athletes to determine if these measures predict lower extremity injury risk. The study tested hip abduction, external rotation, trunk endurance, and abdominal strength in 80 female and 60 male athletes. Males showed greater strength and endurance compared to females. Athletes who avoided injury also showed greater hip strength. Logistic regression revealed that weaker hip external rotation predicted injury risk. The study suggests that improving core stability may help prevent lower extremity injuries, especially in female athletes.
This document describes a study that quantified the physical demands of 21 Hatha yoga postures commonly practiced by older adults. Twenty older adult participants completed a 32-week yoga intervention, where they learned introductory postures for the first 16 weeks and intermediate postures for the second 16 weeks. Biomechanical data including joint angles, joint moments of force, and muscle activation levels were collected while participants statically held each posture. The results provide physical demand profiles for each posture that illustrate the ranges of motion, efforts required to maintain the poses, and activated muscle groups. These profiles can help instructors design safe and effective yoga routines for seniors.

Comparison of 3 d shoulder complex kinematic part 1Satoshi Kajiyama
This study compared shoulder complex kinematics between individuals with and without shoulder pain. Transcortical bone pins were inserted into the clavicle, scapula, and humerus of 12 asymptomatic and 10 symptomatic individuals. Angular positions of the sternoclavicular, acromioclavicular, and scapulothoracic joints were measured during shoulder motions. Differences were found between groups for sternoclavicular and scapulothoracic joint positions, with symptomatic individuals demonstrating less sternoclavicular posterior rotation and scapulothoracic upward rotation. However, the magnitude of differences was small and clinical implications are not fully understood.
This study aimed to compare the ratio of vastus medialis obliquus to vastus lateralis muscle activity (VMO:VL ratio) between healthy subjects and those with patellofemoral pain (PFP) during different types of quadriceps muscle contractions. The study found that patients with PFP had significantly lower VMO:VL ratios compared to healthy subjects. Additionally, isotonic exercises elicited more favorable muscle activation patterns than isometric exercises for PFP patients. This suggests PFP may be associated with abnormal vastus muscle activation that certain exercises could help address.
This document summarizes and discusses several research studies related to manual therapy and musculoskeletal conditions:
- One study found no additional benefit of adding neck manual therapy to treatment for shoulder impingement syndrome. Reasons may include a lack of sufficient dosage or benefits for patients without neck problems.
- Another study compared the effects of active craniocervical flexion exercise versus passive mobilization on cervical range of motion and pain in patients with chronic neck pain, finding greater short-term pain relief from exercise.
- A third study classified low back pain patients according to an existing system and found most classifications remained stable over 10 days, though differences between subgroups were small. Classification may need to consider psychological factors to be useful.
This document summarizes a study that examined the effectiveness of retro walking (backward walking) in patients with chronic osteoarthritis of the knee. 30 patients with grade 3 knee osteoarthritis underwent 10 minutes of retro walking per day on an inclined treadmill for 10 days. Outcome measures assessed before and after the intervention included pain, stiffness, physical function via the WOMAC index, knee extension lag, dynamic balance, and parameters of forward walking. The results showed statistically significant improvements in all outcome measures following the retro walking intervention. The study concluded that retro walking is an effective approach for reducing symptoms and improving physical function in patients with osteoarthritis of the knee.
EMG of the Transverse Abdominus and Multifidus During Pilates ExercisesGrandFinalTechnologies
This study evaluated the intensity of muscle activation in the transverse abdominis and multifidus muscles during four Pilates exercises using electromyography. Eight healthy women performed exercises including shoulder bridges, leg circles, and scissors. The results found that shoulder bridges and variations extending the right or left leg produced greater co-activation of the transverse abdominis and multifidus muscles compared to other exercises. Therefore, these exercises are most effective for rehabilitating lumbar spine stability through activation of the core muscles.
This study examined muscle activation patterns in the lower extremities during different squat techniques. 28 healthy subjects performed squats with neutral alignment (control), intentional frontal plane malalignment (medial knee displacement), and sagittal plane malalignment (anterior knee displacement). Electromyography was used to measure muscle activation in the quadriceps, hamstrings, and gastrocnemius. Results showed altered muscle activation patterns during the malaligned squats, with decreased quadriceps activation during medial knee displacement and changes in quadriceps and hamstring activation timing during anterior knee displacement compared to the control squat. The study provides information on how muscle activation changes with different squat alignments.
The document examines back muscle activity during three traditional mat Pilates exercises - swimming, single leg kick with static prone back extension, and double leg kick - through surface electromyography of healthy adult females. The study found that swimming increased lumbar extensor muscle activity the most at 29% on average compared to the other two exercises. Double leg kicking produced significantly more back muscle activation than single leg kicking. Overall, back muscle activation during the exercises ranged from 15-61% of participants' maximum voluntary isometric contraction levels.
This study compared the effectiveness of global postural reeducation (GPR) to segmental exercises (SE) in treating scapular dyskinesis associated with neck pain. 30 patients were randomly assigned to 10 weeks of GPR or SE. Both groups improved in upper extremity and neck function and pain. However, only GPR improved physical and mental quality of life. When comparing groups, GPR was superior in improving pain and physical quality of life. This preliminary study suggests GPR may be more effective than SE for reducing pain and improving well-being in patients with scapular dyskinesis and neck pain.
Correlación entre equilibrio estático y autonomía funcional en mujeres de eda...Nadia Mendoza C.
This study examined the correlation between static balance and functional autonomy in elderly women. Stabilometric assessment was used to measure balance, including lateral displacements, anterior/posterior displacements, and elliptical area. Functional tests from the LADEG protocol assessed autonomy, including a 10m walk, getting up from seated/prone positions, moving around, and dressing/undressing. The results showed that women who took longer to get up from the prone position had greater mean amplitudes of lateral and posterior displacements and a larger elliptical area, indicating greater instability. This suggests that balance is correlated with functional tasks requiring rising from the floor in sedentary elderly women.
The document describes a study that examined the effects of scapular stabilization exercises on type 2 scapular dyskinesia in subjects with shoulder impingement. The study involved 7 male patients who underwent a protocol of closed kinetic chain exercises focused on the scapula 3 times per week for 2 weeks. Outcome measures of shoulder pain/disability (SPADI) and lateral scapular slide were taken before and after the intervention. The results found a statistically significant improvement in both outcome measures following the scapular stabilization exercises, suggesting that the exercises are effective in treating type 2 scapular dyskinesia.
1) The study examined electromyographic activity of the thigh muscles during single-leg squats and step-ups in 18 healthy subjects.
2) It found that both exercises produced high levels of quadriceps activation, reaching over 200% of maximum voluntary contraction.
3) Single-leg squats and step-ups were concluded to be effective rehabilitation exercises that could be performed without weights or equipment and may help protect the anterior cruciate ligament graft during recovery.
1) The study assessed the influence of vastus muscle activity on patellar kinematics in subjects with and without patellofemoral pain.
2) Electromyography was used to measure vastus muscle activity and kinematic magnetic resonance imaging was used to measure patellar displacement and tilt.
3) Increased vastus medialis longus muscle activity was associated with greater lateral patellar displacement at 27 degrees of knee flexion in subjects. Increased vastus medialis muscle activity was also associated with abnormal patellar kinematics in some positions of knee flexion in subjects.
The study compared the effects of hollowing and bracing exercises on the cross-sectional areas of abdominal muscles in middle-aged women over six weeks. Magnetic resonance imaging scans before and after the exercises showed that bracing exercises significantly increased the areas of the left rectus abdominis, both internal and external obliques, while hollowing exercises significantly increased the areas of the left and right transversus abdominis and left rectus abdominis. Between the groups, bracing exercises led to greater increases in the right transversus abdominis, left internal oblique, and both external obliques. The study concluded that bracing exercises are more effective than hollowing exercises at activating the abdominal muscles.
This study examined the intertester reliability of using James Cyriax's system for assessing patients with shoulder pain. Two experienced physical therapists independently evaluated 21 cases of painful shoulders using Cyriax's evaluation method. They classified the cases into specific shoulder lesions or indicated that the case did not fit the Cyriax model. The therapists agreed on the classification for 19 of the 21 cases, showing 90.5% agreement. Statistical analysis found "almost perfect" agreement between the therapists. Both therapists also agreed on the same 4 cases that did not fit the Cyriax model. The results demonstrate that Cyriax's evaluation can be a highly reliable method for assessing patients with shoulder pain.
This study examined compliance with the Shaker Exercise, an exercise designed to strengthen the suprahyoid muscles, among 26 healthy older adults over 6 weeks. It found that while the exercise improved biomechanical measures of swallowing, only 50% completed the full 6 weeks and 70% achieved the isometric exercise goal. Most dropouts occurred in the first 2 weeks, and the isokinetic goal was easier to achieve than the isometric goal. The exercise was associated with mild muscle discomfort that decreased over time. A structured, progressive program is needed to fully achieve the exercise goals.
Slope walking causes short-term changes in soleus H-reflex excitability. Downslope walking reduces the Hmax/Mmax ratio more than level walking, indicating decreased spinal excitability. Upslope walking increases the Hslp/Mslp ratio and decreases rate-dependent depression, suggesting increased spinal excitability. These changes recover within 45 minutes. The effects of slope walking on spinal excitability are determined by the specific slope and likely related to differences in muscle activity and afferent feedback required for different slopes.
This study compared the effectiveness of two rehabilitation programs for acute hamstring strains. Twenty-four athletes with hamstring strains were randomly assigned to either a static stretching, isolated strengthening, and icing program (STST group) or a progressive agility, trunk stabilization, and icing program (PATS group). The PATS group had a significantly shorter average time to return to sports (22.2 days vs 37.4 days) and lower reinjury rates both within 2 weeks of returning (0% vs 54.5%) and within 1 year (7.7% vs 70%) compared to the STST group. A rehabilitation program including progressive agility and trunk stabilization exercises was found to be more effective for returning athletes to
In this study of 277 post-menopausal women, the researchers found:
1) Higher bone mineral density was associated with increased severity of disc space narrowing at both the lumbar spine and femoral sites.
2) There was no association found between bone mineral density and severity of osteophytes.
3) Biochemical markers of bone resorption (CTX levels) decreased with increased severity of disc space narrowing, but were not associated with osteophyte severity. This suggests disc space narrowing may have a protective effect against bone loss through decreased bone resorption.
20190410 Aquatic exercises improves BMD in postmenopausal womenJulie Tzeng
1) The study assessed the effects of a high-intensity jump-based aquatic exercise program on bone mineral density (BMD) and functional fitness in postmenopausal women. 2) The training group participated in 30-minute aquatic exercise sessions involving high-intensity jumping thrice weekly for 24 weeks, while the control group did not exercise. 3) The training group demonstrated significant increases in BMD at the total femur, lumbar spine, and whole body compared to the control group, as well as improvements in chair stand and time up-and-go test performance.
1) The study compared muscle activity in the thoracic and lumbar erector spinae muscles and spinal curvature during prone trunk extension exercises between subjects with and without slouched thoracic posture.
2) While total erector spinae muscle activity did not differ between groups, subjects with slouched posture showed decreased selective recruitment of the thoracic erector spinae pars thoracis muscle and increased thoracic kyphosis and lumbar lordosis during the exercises.
3) The findings suggest exercises to strengthen the back in individuals with slouched posture need to maintain a neutral spine posture and facilitate muscle activity in the thoracic erector spinae to be effective.

Abstract—Lymphadenopathy is one of the commonest presentation in inflammatory and neoplastic cases. Pathological diagnosis of enlarged lymph nodes is crucial in further management of patients. Fine Needle Aspiration cytology (FNAC) is quick and cost effective OPD procedure for establishing etiology of enlarged lymph nodes. This study was aimed to observed the pattern of lymphadenopathy as per FNAC and its diagnostic accuracy assuming histopathology as gold standard. This study was conducted on two hundred and thirty one consecutive enlarged lymph nodes attended for FNAC in a secondary care level Government Hospital, Gandhi Nagar, Jammu in a study period of two and a half years. Lymph nodes of these cases were aspirated and subjected to cytomorphological evaluation with Papanicolaou (PAP) and Giemsa stain. After that histopathological examination was done of excised biopsies. Then pattern of lymphadenopathy as per FNAC was observed and its diagnostic accuracy was found out assuming histopathology as gold standard. Maximum number of patients was in the age group of 21-30 years age group with male to female ratio 1.2:1. Out of 231 lymphadenopathy cases 4 remain inconclusisve whereas 200 (88.11%)cases were benign and 27 (11.89%) were malignant including 14 (6.1%) cases of metastatic tumors. Among benign cases, majority had non specific reactive lymphadenitis (42.29%) followed by tubercular lymphadenitis. And among malignant tumors, metastatic tumors (6.1%). were most common. Diagnostic accuracy of FNAC was observed as fairly good i.e. ranging from 100% to 83.3% in various type of lymphadenopathies. So it can be depicted that FNAC is very useful first line investigation in patients presenting with enlarged lymph nodes especially in secondary level health care hospitals/centers where advanced diagnostic modalities are not available. The suspicious cases can always be referred for further evaluation.

Abstract—Lymphadenopathy is one of the commonest presentation in inflammatory and neoplastic cases. Pathological diagnosis of enlarged lymph nodes is crucial in further management of patients. Fine Needle Aspiration cytology (FNAC) is quick and cost effective OPD procedure for establishing etiology of enlarged lymph nodes. This study was aimed to observed the pattern of lymphadenopathy as per FNAC and its diagnostic accuracy assuming histopathology as gold standard. This study was conducted on two hundred and thirty one consecutive enlarged lymph nodes attended for FNAC in a secondary care level Government Hospital, Gandhi Nagar, Jammu in a study period of two and a half years. Lymph nodes of these cases were aspirated and subjected to cytomorphological evaluation with Papanicolaou (PAP) and Giemsa stain. After that histopathological examination was done of excised biopsies. Then pattern of lymphadenopathy as per FNAC was observed and its diagnostic accuracy was found out assuming histopathology as gold standard. Maximum number of patients was in the age group of 21-30 years age group with male to female ratio 1.2:1. Out of 231 lymphadenopathy cases 4 remain inconclusisve whereas 200 (88.11%)cases were benign and 27 (11.89%) were malignant including 14 (6.1%) cases of metastatic tumors. Among benign cases, majority had non specific reactive lymphadenitis (42.29%) followed by tubercular lymphadenitis. And among malignant tumors, metastatic tumors (6.1%). were most common. Diagnostic accuracy of FNAC was observed as fairly good i.e. ranging from 100% to 83.3% in various type of lymphadenopathies. So it can be depicted that FNAC is very useful first line investigation in patients presenting with enlarged lymph nodes especially in secondary level health care hospitals/centers where advanced diagnostic modalities are not available. The suspicious cases can always be referred for further evaluation.
This summary provides an overview of a retrospective study analyzing seasonal variation in cases of non-neonatal tetanus (NNT) over a 7-year period from 2004-2010 at a hospital in Jaipur, India. The study found that post-monsoon season had significantly more NNT cases than other seasons each year. Specifically, over one-third of total cases and deaths occurred in post-monsoon months of June-July and November-December. Additionally, winter season had the lowest number of cases but the highest case fatality rate of NNT. The study aims to better understand seasonal trends in NNT occurrence to help guide future elimination strategies.
Suicidal Ideation in Geriatric Population of Jaipur City-Physical, Social and economical problem of geriatrics lead to disturbance in their psychological health and may lead to psychiatric disorders. This study is aimed to found out the suicidal tendencies in geriatric population of Jaipur city. For the study 990 geriatric individuals were identified by 30 cluster technique was adopted to cover whole city. Questions related to suicidal ideation were asked along with other socio-demographic variables. Collected data were analyzed as percentage and proportion and to find out the associated socio-demographic factors chi-square test was used. Suicidal Ideation was found in 6.77% of elderly and this Suicidal Ideation was found to be associated with age, education and present occupation of elderly. It was found significantly more in elderly who lost their spouses. Housing condition and personal hygiene were found to be directly proportional to suicidal ideation i.e. poorer the housing condition and personal hygiene more the chances to have suicidal ideation.
Abstract— Spiritual or compassionate care involves serving the whole person i.e. physical, emotional, social, spiritual etc dimensions of health. Spirituality has now been identified globally as an important aspect for providing answers to many questions related to health and happiness. The World Health Organization is also looking beyond physical, mental and social dimensions of the health i.e. the spiritual health and its impact on the overall health and happiness of an individual. Spiritual commitment tends to enhance recovery from illness and surgery also. Spiritually is transpired both in order to comfort the dying and to broaden one's own understanding of life at its ending. Spiritual beliefs can help patients cope with disease and face death. So it should be necessarily be add-on in critical stage of disease. Nowadays in some of medical schools in developed countries has included as a curreculam of patient care. Now it is the time that all Medical Colleges should include educating their students about spiritual health care in comprehensive patient care. Medical Council of India should also take some action in this direction.
Abstract—By providing proper architecture as per the need and behaviour of the individuals a person may be satisfied with surrounding that may affect spiritual health of individual and in turn the overall health. So this study was conducted on two type of housing society with the aim to find out relationship between type of architecture, interpersonal relationship and spiritual health of their residents.
Methodology: A comparative observational was conducted on two type of housing society having same SES status class I but with different type of architecture. Various components of architecture of their houses was assessed of these houses and general information gathered from head of family. Interpersonal relationship of societies was assessed by applying 9 itemed self reported Relationship Structures (ECR-RS) questionnaire for neighbors on head of family. Spiritual health of head of family was assessed with Spiritual Health Assessment Scale (SHAS). The relationship between type of architecture, interpersonal relationship and level of spiritual health was inferred by Chi-square test and Unpaired 't' test.
Result & Conclusion: It was also found out that Interpersonal relationship were significantly better of society having architecture preferring more of comfort and ambiences than safety and vice versa. Likewise spiritual health score was observed significantly higher in occupants having architecture preferring more of comfort and ambiences than safety and vice versa.

Abstract—Epidemiological study of Rivers State University of Science and Technology Port Harcourt, Nigeria was carried out to identify the morbidity pattern in the University community in order to establish the current health status and trends. This study utilized secondary morbidity data sourced from Health Services Department. Data on staff mortality were obtained from the Personnel/Establishment Division. Methods employed for data collection were health records survey and data collection sheets. Morbidity information required were date, sex, age, department, card number and diagnosis of each case. Information required for each mortality case was date, sex, age, department, salary level and the cause of death. Of all cases of morbidity, communicable diseases comprised 17.5%; non-communicable diseases 24.1%, generalized disease symptoms 55.2% and others 3.2%. The study revealed that the leading causes of morbidity in the University were fever/headache/cold (36.9%), hypertension (13.6%), generalized body pain (7.5%), abdominal pain/vomiting (6.7%) and diabetes (4.9%). Hypertension emerged the second major cause of morbidity among the staff and males had higher rate of morbidity compared to females. It was also concluded that although mortality was increasing with time but there was no sex wise significant difference in mortality trend. It was recommended among others that Diabetes Mellitus and Hypertension being silent killers should be monitored regularly within the University community. Also the current practice of manual data entry should be replaced with computerized data system for better health records management.
Abstract— Cerebral palsy (CP) is the most common physical disability of childhood. Children with CP frequently grow slowly and are more prone to fractures. So this study was aimed to explore relationship of bone mineral density (BMD) with cerebral palsy by case-control study. This study was conducted at Department of Physical Medicine and Rehabilitation of Sawai Man Singh Medical College, Jaipur. Hip bone and spine bone was used to assess BMD. Bone mineral density was measured by DEXA in both groups i.e. study group and control group after ensuring the comparability of both groups. Difference in means of BMD in both the groups was inferred by unpaired student's’ test of significance. It was found in this study that bone mineral density of hip well as spine was significantly lowered in cerebral palsy cases.
Association of Dental Diseases with Oral Hygiene in School Children of Rural Rajasthan, India-Oral diseases are health problem of industrialize well as developing countries because of its high prevalence. In developing countries these diseases are given less impotance because of scarcity of resources but when these dental diseases remain untreated it can cause permanent toothache and disability. It can increase school attendance and intern lead to complication and expensive treatment. A community based study was conducted in rural area of Jaipur district to find out the association of dental diseases with oral hygiene. From schools of Amer tahsil of Jaipur district 1600 students were examined for dental diseases and interrogated for oral hygiene. Association of oral hygiene with dental diseases like Dental Carries, Dental Fluorosis, Malocclusion and Periodontitis was found out with chi-square test. It was revealed that Dental diseases like Dental Carries, Dental Fluorosis, Malocclusion and peridontitis all are associated with oral hygiene. Mouth rinsing frequency and teeth cleaning frequency is inversely proportion in Dental Carries but is directly proportional in Dental Fluorosis, Malocclusion and Periodontitis
Abstract—Diabetes Mellitus is a lifestyle disease it is increasing with increase of urbanization. It is a side effect of development. Nowadays with the development of community it is also on increase trend. So this study was conducted on 250 patients of diabetes attended at Diabetic Clinic of SMS Hospital Jaipur, with the aim to find out socio-demographic profile of these diabetes cases. General information about the these case was gathered in a pre-designed semi-structured performa. It was found in this study that majority of cases were in age group of 31 to 45 years with slight male dominance. Education wise majority were Graduate followed by secondary educated and others. Likewise occupation wise majority were either unemployed of professional. Majority of cases were from Socio economic Class II and III. So it can be concluded that diabetes is a disease of middle age slight male dominance and of educated middle class individuals. Further studies are required to establish this fact.
Comparison of pre-mixed and sequentially intrathecal administration of Clonidine with hyperbaric Bupivacaine in caesarean sections-Adjuvant and hyperbaric Bupivacaine mixing in a single syringe before injecting the drugs intrathecally is an age old practice. It may cause intraoperative hemodynamic changes. Administering local anesthetic and the adjuvant separately may minimize these side effects. So this study was aimed to compare effect of administering hyperbaric Bupivacaine and Clonidine intrathecally as a mixture and sequentially in cases undergoing caesarean section (CS). This study conducted at a District Hospital of Rajasthan in year 2013. Cases undergoing elective caesarean sections were divided into two groups by chit box method each of two groups consists of 30 cases. One group (Group A) is given mixture of Clonidine (75 mcg) and hyperbaric Bupivacaine 0.5% (10 mg) intrathecally, whereas other Group B received Clonidine (75 mcg) followed by hyperbaric Bupivacaine 0.5% (10 mg) through separate syringes. It was found that duration of analgesia was significantly longer in Group B (466 ± 18.2 min) in which the drug was given sequentially than in Group A (334 ± 16 min). Likewise, the time to achieve highest sensory and complete motor block was significantly less in Group B than Group A. So it can be depicted that administering Clonidine and hyperbaric Bupivacaine in a sequential manner is better than mixing of the two drugs.
Abstract—Obesity is the major global nutrition concern. Modernisation and urbanisation have led to changes in dietary and lifestyle factors which are contributing to the increased prevalence of overweight and obesity.
Objective: To find out various life style risk factors for obesity among school children of affluent families aged 10-18 years in Jaipur city.
Methods: A cross-sectional study in ten randomly selected schools of Jaipur city with tuition fee > 18000 ₹/year was conducted from July 2012 to April 2013. 1610 students of class V to XII were included and their detailed life style history with anthropometric measurements was recorded after their informed written consent. Indian Academy of Pediatrics' growth Monitoring Guidelines for children from birth to 18 years was followed for defining and classifying obesity.
Result: 364 (22.61%) participants were found obese/overweight. Watching television during meals, frequency of main meals outside home per month, frequency of snacks outside home per week and duration of television/ computer watching per day were found significant predictors of overweight/ obesity on binary multivariate logistic regression method.
Conclusion: The present study highlights childhood overweight/obesity is an emerging health problem (22.61%) and lifestyle factors are important risk for it.
Abstract—Dermatitis artefacta is a self-inflicted dermatologic injury with underlying primary psychiatric condition. Precipitating factors ranges from simple anxiety to interpersonal conflicts and several personality disorders including obsessive compulsive disorder, depression and psychotic disturbances. The diagnosis of this entity is often missed. Herein, we are reporting a case of dermatitis artefacta with description of its various manifestations.
This review article summarizes research from the Spinal Deformity Study Group on classifying spondylolisthesis based on sagittal spinopelvic alignment. The classification defines 6 types based on grade of slip, pelvic incidence, and spino-pelvic alignment. Research found abnormal pelvic and spinal parameters in spondylolisthesis patients compared to controls. For low grade slips, some have increased pelvic tilt and lordosis ("shear" type) while others have decreased parameters ("nutcracker" type). High grade slips were found to have two alignment subgroups - a "balanced" group standing with high sacral slope and a "retroverted/unbalanced" group with low sac
This study examined the relationship between lumbar scoliosis and osteoporosis in postmenopausal women. The researchers analyzed dual-energy x-ray absorptiometry (DXA) scans of 900 randomly selected postmenopausal women aged 64-88 years old. They measured the Cobb angle to assess lumbar scoliosis and bone mineral density at the femoral neck, total hip, and spine to assess osteoporosis. They found that both the incidence and degree of lumbar scoliosis, defined as a Cobb angle over 10 degrees, increased significantly with age. However, after adjusting for covariates like age, weight and ethnicity, there was no significant association between bone mineral density at any site and the Cobb angle.
This study aims to investigate the relationship between posture, spinal balance, muscle fatigue, and symptoms in patients with lumbar spinal stenosis before and one year after surgery. Over 120 patients will undergo clinical assessments, questionnaires, radiological imaging, biomechanical testing, and activity monitoring at baseline, 6 months post-op, and 1 year post-op. Biomechanical testing will involve measuring posture and gait with and without induced paraspinal muscle fatigue. The study aims to determine if outcomes correlate with severity of stenosis, muscle degeneration, compensation strategies, and changes after surgery. Results may help understand the condition and guide treatment and rehabilitation.
This study investigated age and gender differences in three mandibular parameters (gonial angle, ramus height, and bigonial width) using digital panoramic radiographs of 209 dentate Jordanian subjects. The study found that gonial angles and bigonial widths increased with age while ramus height first increased from ages 11-29 and then decreased with age. Males generally had higher parameter values than females. Statistically significant differences were seen between various age groups for the three parameters. The study supported that mandibular morphology is influenced by both biomechanical forces and biochemical alterations with aging.

1) The study examined age-related changes in knee laxity, quadriceps strength, and walking patterns in young, middle-aged, and older adults without knee OA, and compared them to individuals with knee OA.
2) They found that older adults had weaker quadriceps strength compared to younger groups, but knee laxity was only greater in those with OA and not different between middle-aged and older controls.
3) During walking, older adults exhibited greater quadriceps activity but similar knee motion compared to younger groups, unlike those with OA who had less knee flexion and more knee adduction.
This study investigated variability in musculoskeletal traits in laboratory rats. The weights of three hindlimb muscles (tibialis anterior, extensor digitorum longus, and soleus) and tibia bone length were measured in around 500 outbred rats divided into male and female groups at two ages. Significant variability was found in muscle weights, ranging from around 2-fold differences between individuals of the same sex and age. Strong positive correlations were observed between the weights of tibialis anterior and extensor digitorum longus muscles, as well as between muscle weights and tibia bone length. Weaker correlations were found between muscles of different fiber types. This data will be used in future genome-wide association studies to identify specific genes
Vertebral fractures were the strongest marker of low bone mineral density (BMD), with two-thirds of women with vertebral fractures found to be osteoporotic. Half of women with hip or humerus fractures and one-third with forearm fractures were osteoporotic. Previous fractures correlated inversely with BMD, with women having vertebral or hip fractures, or multiple fractures, more likely to have lower BMD and osteoporosis. Investigation for osteoporosis is warranted for all women aged 55-75 presenting with a low-energy fracture, prioritizing those with vertebral, hip, or multiple fractures.
This study investigated age and gender differences in three mandibular parameters (gonial angle, ramus height, and bigonial width) using digital panoramic radiographs of 209 dentate Jordanian subjects. The results showed that males had slightly higher measurements than females for all three parameters. Gonial angle and bigonial width increased with age while ramus height first increased from ages 11-29 and then decreased with increasing age. Statistically significant differences were found between several age groups for each parameter, suggesting the mandible undergoes remodeling changes with aging.
The Incidence of Traumatic Posterior and Combined Labral Tears in Patients Un...Lennard Funk
Posterior and combined labral tears are more common than previously thought, especially in young active populations. The study reviewed 442 patients undergoing shoulder stabilization surgery and found that posterior and combined tears accounted for 47% of cases, compared to only 53% being isolated anterior tears. Rates of posterior and combined tears were even higher in sporting populations (52%) compared to non-sporting populations (32%). Rugby players in particular had a high rate of posterior and combined tears (53%). The study concludes that posterior and combined shoulder instability is more prevalent than reported, especially in contact sports.
Thoracolumbar braces are commonly used to treat adolescent idiopathic scoliosis. While braces aim to control curve progression through applied forces over time, their effectiveness is disputed due to inconsistent patient populations and evaluation methods across studies. Ideal candidates are those with curves between 30-40 degrees or less than 30 degrees who are at high risk of progression. Studies found braces successful in preventing progression over 6 degrees in right thoracic curves 25-35 degrees. However, wrong indications or inadequate forces can lead to treatment failure. Further research on brace biomechanics aims to better understand correction effects and pressure distributions to optimize brace design and prescription.

ABSTRACT: A flexible ankle joint is suggested to be a contributing factor for sport performance, body
control. The purpose of the present study was to investigate the differences in proprioception in static and
dynamic movements between subjects with good ankle joint mobility (FL) and poor ankle joint mobility (IN) in
male adolescent handball players. The dorsiflexion and plantarflexion of the ankle ROM was measured, at knee
extension angle of 120°, with a goniometer. 26 male handball players participated (21.1 ± 4 yrs, 80.8 ± 10 kg,
182 ± 7.38 cm). Furthermore, the players fulfilling previously recommended criteria were assigned to the
flexible (n = 6) and inflexible (n = 6) groups and executed two test of static and dynamic movement (BESS Test
and Star Excursion Balance Test). Results of the T TEST on IMB SPSS 26 revealed a significant (p < 0.05)
group effect as (FL) group had less errors than (IN) group on BESS test. In addition, the results of the total sum
on stable and unstable surface in star excursion test showed significant differences in the directions:
anterolateral (7.4), posterolateral (8.6), posteromedial (7.9), medial (10.8) and anterior medial (8.1). In
conclusion, there is a correlation between poor ankle joint mobility and poor proprioception, balance control and
athletic movements.
KEYWORDS: ankle stability, ankle joint mobility, BESS test, handball athletes, injury risk, star excursion

This study aimed to establish normative measurements of cervical spinal canal and spinal cord dimensions based on MRI scans of 140 healthy volunteers. The researchers found that dimensions varied significantly based on sex, spinal level, height, and to a lesser extent age. They defined normal ranges for sagittal diameters and cross-sectional areas of the spinal canal and cord at C1, C3, and C6 levels, accounting for sex, level, age and height. Having defined normal cervical spinal anatomy will aid radiologists in assessing potential spinal stenosis.
Morphohistometric study of the ligamentum flavum in cervical,thoracic and lum...Prof. Hesham N. Mustafa
ABSTRACT Anatomic characterization and fine structure of the human ligamentum flavum (LF), especially at different spinal levels, represent an attractive focus for the scientific and surgical application. Descrip-tive anatomical and structural study of LF at the cervical, thoracic and lumbar levels of the vertebral column in human cadavers is carried out here. The aim of the work is to clarify the anatomical features and fine structural differences in the human LF at different vertebral levels (cervical, thoracic and lumbar). Specimens of vertebral column were ob-tained from 34 human preserved cadavers. Their average age ranged between 56 and 69 years. Morphometric parameters including height, width and thickness of the ligament flavum at the mid-levels of cervical, thoracic and lumbar regions were measured. Sections obtained from different levels were stained with different stains. Morpho-metric measurements involved the relative elastic area, relative collagen area, elastic area% and collagen area% were measured.The results of the height, width and thickness of the LF at different spinal levels showed gradual increase in their mean values respectively. The LF midline gaps were found in the cervical, thoracic and lumbar regions. The morphometrical measure-ments showed that the average elastic area was highest in the cervical region and lowest in the tho-racic region. In the lumbar region, the percentages of both elastic area and the collagen area were nearly the same. The characterization of morpho-logical and histological aspects of the LF at differ-ent spinal levels will be of great importance for ap-plications in spinal surgery, biomechanical and physical rehabilitation of vertebral column.Keywords: Ligamentum Flavum – Spinal – Collagen and elastic fibers

The study retrospectively analyzed 58 patients with TMD using CBCT images. Bone quality was assessed and patients were classified as having or not having TMJ hypermobility. The results found no statistically significant difference in bone quality between the two groups, indicating no direct relationship between bone quality and TMJ hypermobility in TMD patients.
Thoracolumbar braces for the treatment of A.I.S.Is there any difference?Alexander Bardis
This document discusses adolescent idiopathic scoliosis (AIS) and the treatment of AIS using thoracolumbar braces. It provides an overview of the natural history and progression of AIS, current treatment options including bracing, and the biomechanical effects and effectiveness of bracing. While bracing aims to control curve progression through applied forces on the torso, there is conflicting evidence on its effectiveness. Further research is needed to better understand the biomechanical actions of braces and how they may stimulate asymmetric growth through the Hueter-Volkmann principle to correct spinal curves.

Abstract—Kyphosis and lordosis changes might be related to back extensor weakness and
osteoporosis. The purpose of this study was to find out the correlations between thoracic kyphosis,
lumbar lordosis with back extensor strength (BES) and bone mineral density (BMD).
Methods: Thoracic kyphosis, lumbar lordosis, maximal isometric strength of the back extensors and
BMD of the lumbar vertebral were evaluated in 47 elderly (50-75 years old)women. BMD of the lumbar
vertebral was measured using Dual-Energy X-Ray Absorptiometry (DEXA) and kyphosis and lordosis
degree were assayed using a flexible ruler. The maximal isometric strength of the back extensors was
measured using an isometric manual muscle tester (MMT). Data were analyzed using ANOVA and
independent t-test at p≤0.05 level of acceptance.
Results: A significant reverse correlation was shown between BES and kyphosis (p=0.044, r=-0.30).
No significant correlation were found between BES and lordosis degree, nor between lumbar vertebral
BMD and, both, kyphosis and lordosis degrees. However, there was a significant difference in BES
between three groups with various degree of kyphosis (p≤ 0.05).
Conclusion: It can be concluded that the severity of thoracic kyphosis may be influenced by BES. So,
stronger back extensor can prevent thoracic kyphosis despite decreased BMD.
Key Words: Bone Density, Muscle Strength, Kyphosis, Lordosis.
I. INTRODUCTION
In people who are afflicted with osteoporosis it has been observed that increasing the degree of
vertebrae under pressure and progressive changes of pulling line of body gravity will usually result in
anterior deformity of the spinal cord or kyphosis.1
The kyphosis occurrence in these people could be
accompanied with height loss, rib-cage deformity, respiratory dysfunction, and abdominal protrusion.2
However, no significant relationship was indicated between BMD and kyphosis deformity according to
Mika et al. who stated that any reduction in BMD could not lead to increasing the angle of kyphosis if
back extensor strength (BES) and degree of spinal cord stability had not changed.2
According to the
findings of the previous studies,2,3
weak back muscles are observed among people who afflicted with
kyphosis,3
although, this relationship was not significant in a previous study 2
but, when these subjects
were categorized according to their BMD, this relationship was significant; in other words, the kyphosis
angle was more in individuals who had weaker back muscles, and this difference increased with
lowering of BMD.
Women are more exhibited than men to low bone mass and its complications, so that fracture in hip
bone is 5.2 and in vertebra is 10 in women v/s 1 in men4
.
Generally, women have weaker back muscles in compare to males, and reduced strength of these
muscles has more destructive effects on musculoskeletal system through aging. Sinaki et.al5
indicated

that the stronger the back extensor, the smaller the thoracic kyphosis and the larger the lumbar lordosis
and sacral inclination. They concluded that back extensor strength is an important determinant of
posture in healthy estrogen-deficient women. However it is cleared that the back extensors strength
lowers and angle of kyphosis increases with age. According to Sinaki et al.5
back extensors strength had
a significant negative correlation with thoracic kyphosis and a positive correlation with lumbar lordosis
and sacral inclination which can be explained considering the anatomical position of these muscles. It is,
also, indicated that life style has a relationship with posture, which this could be related to the amount of
activity of daily living and in turn BES5
. So, the aim of this study was to find out the relationship
between spinal cord alignment in sagittal plane, BMD and BES in elderly women.
II. METHODOLOGY
A cross-sectional analytic type of observational study was carried out on 47 elderly women attending at
centre for bone marrow density test.
Approval for this study was taken from Ethics committee of Yadegar - e- Imam Khomeini (RAH)
Shahre-rey Branch, Islamic Azad University. After taking approval from institutional Ethical
committee, study subjects were selected. Age 50-75 years old women were selected for this study from
the subjects who referred at this centre for the bone mass testing. Subjects who had a history of spinal
cord surgery, herniated disc and chronic back pain were eliminated. All subjects completed the consent
form. Finaly 47 eligible women were included in this study. After taking consent from each subject,
these women were interrogated as per predesigned performa and were subjected for further following
assessments.
2.1 Kyphosis and LordosisMeasurements:
Kyphosis and lordosis curves were measured using a flexible ruler as a valid and reliable technique6
. A
fixing instrument was used in order to higher the precision of measuring the spinal cord curves
according to Youdas et al. (2006) 7
. To this, participants were asked to stand in the normal anatomical
position. First lumbar (L1) and second sacral (S2) vertebrae were considered as markers for evaluating
the lumbar curvature. In order to find S2, the posterior superior iliac spine (PSIS) was marked. The
midpoint between the two PSISs was considered as the spinous process of the S2.
To find L1, the examiner pushed the lower back above the iliac crest in order to move the soft tissue
laterally where the two thumbs reach horizontally together on the L4spinous process. The L1spinous
process was identified by counting up the vertebrae. Then, the flexible ruler was located on L1and
S2while a hand pressed on it to abolish the gap between the ruler and the skin. The ruler was put on a
page and the lumbar curve was drawn afterwards8
.
Measurement of the thoracic curvature was done in a similar method to that of the lumbar curvature.
The only difference was that T2 and the joint of T12 and L1 were marked in order to measure the
thoracic curvature9
. The thoracic curve was drawn by using a flexible ruler. Two ends of the curve
reached together, and a L line was drawn whose midline vertically reached the middle of the curve
through the h line. The lengths of h and L lines were calculated and the aforementioned angle was
obtained. The line was drawn from the side of the ruler which touched the skin. The kyphosis and
lordosis angles were measured separately by the tangent method10,11
.

The normal range of kyphosis and lordosis were considered between 20 to 40 degrees and 20 to 45
degrees, respectively12
and all subjects were categorized into three groups of normal, lower than normal
and higher than normal, accordingly.
2.2 Bone Mineral Density
The bone density of the spinewas measured at L2 to L4 using dual-energy X-ray absorptiometry
(DEXA) system (model Lexxos DR, DMS Group, France).The relative degree of risk of fracture
(normal, low, average, and high), and WHO scale (normal, osteopenia, and osteoporosis) was
determined according to T score.
2.3 BES Assessment
The subjects were positioned prone on a treatment table with their hands behind their head and distal
thighs secured to the table with a stabilization strap. The Manual Muscle Test (MMT) dynamometer
(Morgan Hill, CA, U.S.A) was placed such that the center of the force pad bisects a line connecting the
superior/medial angle of the subject's scapulae. A strap was then secured over the dynamometer and
around the underside of the table. To limit the contribution of hamstring activity on trunk extension
strength, the subject’s feet were supported on a bolster in 30◦
of knee flexion. Instructions for the
subjects were to lift their trunk upward with maximal effort. The maximum record in two efforts was
assumed as BES. The test–retest reliability of the force measurements (ICC) for this measure is reported
to be 0.8513
.
2.4 Statistical Method
The normality of the data was assessed using Kolmogorov–Smirnov test. The relationship between the
variables and the difference between the levels of deformity according to weight and age were analyzed
using ANOVA and Pearson correlation coefficient, respectively. Statistical analysis were done using
SPSS 16.0 (trial version) for windows and significant level was set at p≤0.05.
III. RESULTS
In this present study, mean and standard deviation of the variables as per their age group are presented
in table 1. It was observed that although there was a significant difference as per age in weight, BMI and
lordosis but not in other variables studied. (Table 1)

No significant difference was shown in level of kyphosis and lordosis between 3WHO criteria-based
groups (i.e. normal, osteopenia, and osteoporosis) (p>0.05).Relative risk of fracture among 50-60 and
>60 years old is presented in Figure 1;a tendency of having higher relative risk of fracture exists in >60
years old people. There was no significant difference in BES between groups with differentdegree of
lordosis; although, LSD post-hoc test revealed a significant difference between normal and high degree
kyphosis (p≤0.05). (Figure 1)

IV. DISCUSSION
The observations of present study indicate that 57.5 percent of the subjects were inflicted with high
degree of kyphosis and 23.4 percent with high degree of lordosis. Mean BMD in 50-60 years old group
was 0.90±0.28 g.cm-2
against0.84±0.25 g.cm-2
in>60 years old group which is lower than the BMD
(1.066 ± 0.175 g.cm-2
) that reported by Sinaki et.al5
in healthy group. It has to be mention that the
subjects of the present study were the people with pathologic signs of low BMD who were referred by a
physician to "Bone Density Testing Center".Accordingly,34.8 percent of our subjects were inflicted by
osteoporosis and 32.6 percent with osteopenia.
A significant relationship was found between BMD and kyphosis and lordosis angle nor significant
difference in degree of kyphosis and lordosis between normal subjects andosteopenia or osteoporosis
ones. Mika et al.2
also did not indicate a significant relationship between BMD and kyphosis deformity.
They stated that reduced BMD without any changes in back BES and spine stability could not lead to
increasing the angle of kyphosis. However, others 5
did not support this findings. In this regard, a
review14
has reported that the severity of wedging increases as BMD losses, causing greater numbers of
vertebral compression fractures and a further cascade of increasing hyperkyphosis. On the other hand,
few older studies indicated that the changes in spinal-cord soft tissues could increase the kyphosis
angle.5,15
In the present study a significant relationship was found between BES and kyphosis angle. There is a
significant difference in BES according to level of kyphosis, and after performing the follow-up LSD
test it was indicated that in BES between normal kyphosis group and more than normal group that there
was a significant difference existed (p≤0.0.5).
In few studies likes the present one, increased angle of kyphosis was associated with a reduction in
BMD that may be related to other factors such as changes in spinal cord soft tissues. In another study,
no vertebral deformities was reported in only 17 percent of the individuals with kyphosis16
; additionally,
48 percent of the individuals with kyphosis were affected by vertebral deformity accompanied by
reduction in BMD.5
In this regard, Mika et al. according to their multi-variable analysis study stated that
weakness of back muscle is the more important cause for spinal cord deformities than reduced bone
mass when osteoporosis is existing.2
A significant relationship between BES and BMD was also reported in menopause women 17
and
patients with osteoporosis.18
Sinaki et al. indicated that muscle strength reduction was observed
specifically in back muscles not whole body, so that no significant difference was existed in handgrip
test between osteoporosis and healthy group. These findings indicate that the difference in BES between
healthy and osteoporotic groups may be because of pain, discomfort and lack of adequate stimulation of
these muscles.5
In the longer term, both muscle and bone mass increased in patients with rheumatoid
arthritis over a strength training program,19
whilst the increase in lean muscle mass was the best
predictor of gain in femoral bone content and density in exercising children,20
highlighting an existed
relationship between muscle strength and BMD. However, few studies were conductedon lordosis and
its relationship to BMD and BES.
In this present study the degree of lordosis did not indicate any significant relationship with any studied
variables. Gelb et al21
stated that low back lordosis is reduced by age, however, back kyphosis does not
change. These investigators also found that reduced lordosis in elderly individuals is because of lack of

balance in vertebrae at sagittal plane.21
However, Tuzun etal. (1999) suggested that this reduction is a
secondary illness related to increasing of kyphosis.12
Low lordosis was found in 21.3% of the subjects. Significant changes have been observed in level of
lordosis by aging.12,22,23
In a study on relationship between intervertebral discus degeneration and spinal
cord alignment in lumbo-sacral region from the sagittal view it was indicated that discus degeneration
would lead to reduction in lordosis and sacral angle which will cause the hip to turn backward.24
Sinaki
et al. also indicated a positive relationship between BES and lordosis angle which we could say that
BES increase could cause reduction in kyphosis angle and increasing of lordosis angle.5
On the other
hand generally women acquire weaker back muscles comparing to men. By aging, the reduction of these
muscle strength would have more degenerative effects on women muscular-skeletal system.
In the present study possibility of fracture as a result of aging was higher but this difference was not
significant between two groups of 50 to 60 years old and 60 and older. Sinaki et al. 5
state that by aging,
BES is reduced and kyphosis angle is increased; therefore, it could be stated that the age is an important
factor in observing a relationship between BES and kyphosis angle.
V. CONCLUSION
According to the present study, the back extensor muscles have basic role in maintaining the back spinal
cord alignment, and it could be stated that increasing of angle of kyphosis could take place as a result of
reduction in bone mass, and occurrence of postural deformity in osteoporotic individuals has a close
relationship with changes in spinal cord soft tissues the back muscles.
