The document discusses biomechanics of the tibiofemoral joint, including osteokinematics (bone motions), arthrokinematics (joint motions), and the automatic locking/screw home phenomenon. It describes the two degrees of freedom of motion as flexion-extension along a migrating axis and internal-external rotation along a vertical axis. Arthrokinematics involve gliding and rolling motions of the femoral condyles on the tibia during extension. The automatic locking occurs through lateral rotation of the tibia on the femur during the last 30 degrees of extension, increasing joint stability.
this PPT contain detailed kinetics & kinematics of ankle joint & all joints of foot complex, muscles of ankle & foot complex, plantar arches & weight distribution during standing.
Posture - a perquisite for functional abilities in daily life. Posture is a combination of anatomy and physiology with inherent application of bio-mechanics and kinematics. Sitting, standing, walking are all functional activities depending on the ability of the body to support that posture to carry out each activity. Injuries and pathologies either postural or structural can massively change the bio-mechanics of posture and thus affect functional abilities.

Palpation of knee joint can be done in various positions based on the comfort of the patient and therapist. If the patient is sitting, high sitting is a good position to start. If not, supine is an alternative position where the patient is most relaxed; as shown by Hutchinson in the BJSM video.
Practice is the key to master the examination. The students should be aware of the location of the structures in such a way that you should be able to see through the skin and locate the structures underneath. Practice by marking the skin for various structures under the skin.
This powerpoint is intended to give an overview of observation of knee to undergraduate first year students. Students should not forget to do overall comprehensive observation of posture and other body parts before focusing the observation locally at the knee joint.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Editor's Notes
Evolute is the curved path… that medial lateral axis takes
Average axis of rotation is close to lateral epicondyle. This movement causes rubbing of the skin in hinged braces + movement of goniometer during joint ROM assessment.
Axial rotation increases with knee flexion. Total rotation of about 40- 45 degrees. External rotation to internal rotation= 2:1
Minimal rotation at 0 degrees of knee extension
Naming the rotation- based on orientation of tibial tuberosity in respect to anterior distal femur
Naming the rotation- based on orientation of tibial tuberosity in respect to anterior distal femur
Posterior rolling in flexion
Posterior rolling in flexion
Anterior glide in flexion and vice versa
Different from the rotation described earlier
In both closed or open kinematic chain, the knee joint laterally rotates (femur internal rotation in closed and tibia external rotation in open KC)
Medial condyle curves about 30 degrees laterally as it approaches intercondylar groove. Also articular surface of medial condyle extends farther anteriorly than lateral condyle, the tibia is obliged to follow the laterally curved path into full tibial on femoral extension.
