Lower limb neurological examination frequently appears in OSCEs. You’ll be expected to pick up the relevant clinical signs using your examination skills. This lower limb neurological examination OSCE guide provides a clear, concise, step-by-step approach to performing a neurological examination of the lower limb
THE NEUROLOGICAL SYSTEM -
The neurological system controls body functions and is
inter-related to other body systems i.e. a patient with diabetes
may suffer a stroke
LOWER LIMB EXAMINATION ,INSPECTION,PALPATION,TONE ,POWER, The neurologic examination is typically divided into eight components: mental status; skull, spine and meninges; cranial nerves; motor examination; sensory examination; coordination; reflexes; and gait and station.

Also known as GP note, "Pol" note, PP note
Medical students/ pre-interns/ Family physicians use various notes to guide their general practice at the begining, specially drug doses, common treatments for common diseases etc. These "guides" have been used by many seniors but need to be careful revision before prescribing. Hope to update once I go through them completely.

The original teachings of Jesus Christ were an outcome of
Buddhism, says Holger Kersten, a German theology teacher.
Hence one of the titles of the chapters in his book, "The
Original Jesus" (sub-titled 'Buddhist sources of Christianity') is 'Jesus the Buddhist'!

A senior disciple of Ajaan Mun, Ajaan Khao Anālayo was one of the foremost meditation masters of our time. He always preferred to practice in remote, secluded locations and with such single-minded resolve that his diligence in that respect was unrivaled among his peers in the circle of Thai forest monks. In his frequent encounters with wild animals, Ajaan Khao exhibited a special affinity for elephants.

Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

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.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
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

Examination of lower limb in neurology-Short case approach for Final MBBS
1. Examination of lower limb in neurology-Short case approach
Possible cases
1. Hemiplegia: flaccid or spastic
2. Paraplegia/ paraparesis: flaccid or spastic
3. Myopathy
4. Ataxia
5. Foot drop
6. Myasthenia/ NM
In each & every step always think which category this pt best fits.
Possible instructions at the exam
1. Examine the lower limbs of this pt
2. Inspect the gait & procede: pt may be wearing a diaper & catheter, then you must know that pt
can’t walk
3. Inspect the lower limbs of this pt & procede
Procedure
“Time is money”. Cutdown all unnecessary steps/words
Introduce briefly: I am a final year medical student & going to examine you.
Arrange the setting
Cover the curtain
Lit the area if pt is placed in dark/ or atleast lit your torch to show the examiner that you want
adequate light
Commentry can be made at the end or it may be a running commentry
Inspect the pt from the distance
Is he
1. ill looking/
2. in pain/
3. comfortable/
4. looks bed bound/
5. features of urinary or fecal incontinence- Pt with pampers & catheter is likely to have both.
Better not to say “smelly”) /
6. obvious bed sores/
7. posture (if having decorticate, decerebrate)?
“I am going to examine this young/old looking gentleman/lady who is lying comfotably on the bed. He
looks well & not in pain. He is not having any bed sores or features of urinary or fecal incontinence. I
would like to examine his LL.”
Age is particularly important (atleast a rough estimation) in CVS cases.
Use ONLY the terms “gentleman or lady” ( avoid other terms as examiners may unnecessarily
cross ques you how do you know girl etc & waste your time)
Yapa Wijeratne
2. Go near the LL
Inspection of LL
1. Wasting/
2. Fasciculations /
3. Contractures/
4. Deformities/
5. Trophic Ulcers/
6. Rashes (Dermatomyositis)/
7. Localized Inflammation (Myositis)/
8. Muscle Biopsy Scars/tendon release scar in an infant
On inspection there is no wasting /fasciculations/ contractures/deformities/ trophic ulcers
Before you touch the pt ask whether there is any pain in the lower limb? (myositis) : without asking this
you may touch the pt & he may scream in pain & this gives the impression of a good professional.
Thre is no tenderness to touch
Better approach would be asking pt to elevate LLs separately as high as they can
This will elicit obvious
Proximal weakness
Hypotonia: dragging the foot in the bed
Foot drop
Disc prolapse: SLRT+. So you can easily observe as he would not raise above pain.
Added advantages here are you are able to elevate limb upto the point of pain in disc prolapse & you
need not to worry about the tone checking.
But better not to comment about SLRT at that moment & you can perform with lesser force( you may
use just 2 fingers to lift as at any moment pt can put his leg back easily). Focus pt’s face while noting the
angle.
In this pt’s SLRT was 90 degrees B/L
Tone > Power > Then you can do clonus as it takes even a little time if done with tone >Reflexes
You may roll one limb & suddenly lift & release the other limb. This will divert pt’s attention & reveal the
signs well.
Spasticity: initially there is a resistance to both sides. at one point resistance is gives away. clasp knifeLead pipe: Rigidity persisits throughout.
Cog-wheel
Checking for power should be done with one command word.
It is always to better to comment as muscle power is reduced/ normal than comment with grading as
incase of cross questioning, you don’t have an answer how you checked so.
Power was reduced (flexors or the extensors at knee joint on R/S)/ normal (bilaterally)
Reflexes
Then you can do clonus depending on your findings.
Plantar
By this time you have already diagnosed common peroneal nerve palsy/ foot drop or root lesion
Yapa Wijeratne
3. Then go by dermatomal pattern in sensory
If find dermatomal pattern you go above till you find a sensory level. Once you find, check the back also.
You must check the other limb also.
Sir I would like to examine the posterior side as well.
Periperal neuropathy, paralysis will be found.
Superficial abdominal reflexes also can be done at this time.
Superficial abdominal reflexes is a LMN sign.
Umbilicus move to the side to the innervated/ intact group & opposing group is weak.
Accurately localize the level
You may use other side of the tooth pick.
You must check the other limb also. As there can be a crossed hemiplegia (Brown Sequard).
Once you get a sensory level,
I would like to check for other sensory modalities also. (if time permits)
Vibration is better than proprioception to check dorsal column.
B/L Foot drop, only the weakness in plantar & dorsiflexion → sciatic nerve
So check the sensory, check common peroneal & posterior tibial are affected. But the sural is intact
(lateral border of foot).
Foot drop+ affected eversion but big toe extension is preserved. → common peroneal
So check deep & superficial branches of common peroneal. Prick the space between big toe & 2nd toe &
check some other place also
Lateral border
Sole
Either sides: lateral cutaneous/ obturator
If time permits, check the back S2, S3 also.
Foot drop+ affected big toe extension, but able to evert the foot→ L5 root
If pt is in standing position, this can be done by asking the pt to stand with toes(L4,L5) & heel (S1,S2). If
found root pattern, check the sensory in root pattern.
Then do the heel knee shin test.
I would like to check the gait of this pt.
B/L Paraplegia/ paraparesis: flaccid
1. GBS: commonest
2. Spinal shock
3. Transverse myelitis: initially
4. Severe ant horn cell disease
5. Full blown cauda equina lesion
Then how to progress
Spincter control: also has told by now
Yapa Wijeratne
4. Sir I would like to examine the Upper limbs also. So I would know upto which level this process has
ascends.
Wrist tone (T1,C8): if flaccid > power biceps C5,C6 > if weak > check diapragm: single breath count
Get a one breath & count for the maximum 1,2,3,…
I would like to do single breath count
Then check neck flexors by
Flexing the neck
Keeping the hand to resist on the forehead & flex again.
Can check the other side of the neck/ trapezius & check upto accessory nerve level.
If transverse myelitis you have found the sensory level.
Spinal shock, transverse myelitis→pt would be in pain.
Spinal shock: examine the back for spinal tenderness. Or atleast ask
Spastic
Tone is more.
power biceps
BJ/ TJ reflexes
Ask the pt to open the mouth & look at the tongue: hypoglossal
Look at the face: facial nerve
Ask for jaw jerk. But better not to do as due to your mental stress you might hit the mouth
Spastic, but UL normal tone→ look for spinal tenderness
Spastic, sensory in upper abdomen, but UL flaccid
ALS- grossly wasted hands
Lesion at that level: I am suspecting a lesion at C7-8 nerve roots, so I would like to check for the
sensory at that level.
Hemiplegia: flaccid or spastic
Both UL
Spastic hemiplegia. Normal tone in UL→ pyramidal drift
Tone can get compensated later by innervating myotomes. But pyramidal drift persists for some time.
This can be performed, even in the lying position with closed eyes.
Localize stroke. (swallowing in long case. If in short case, pulse, auscultate heart, carotids)
Look at the face/ eyes: if normal, this can be at the internal capsule level. Chronic cases, CN VII palsy get
corrected & treat also.
Eyes: gaze palsy
Hemiplegia: flaccid→polio
Know stool collection etc
AFP/ vaccination schedule
Common peroneal
inspect ULs: hypopigmented areas:
palpate neck of fibula/ ulnar nerves
Ataxia
Yapa Wijeratne
5. head to toe CL features
proximal weakenss is clearly seen in gait. If any waddle, get the pt squat & stand.
Proximal weakenss
Rashes (Dermatomyositis/
Myositis) UL tenderness may be there.
Thyroid: pulse/ tremor
If Stroke: at least tell the examiner that you want to examine the CVS for possible cause
Myasthenia in unexplained weakness. If does not fit for any check for this.
Ask the pt to look up for 20s for myesthenia
Occular myes 50%. In other conditions also having occular involvement in ~80%
Flacccid paralysis
Pt is having B/L flaccid paralysis of LLs & Uls. Tone is reduced at the wrists. C5-6 power is normal. Single
breath count is normal. Neck flexors & extensors have normal power. There is no spinal lesion & no
sensory level.
Pt is having acute flacccid paralysis involving B/L LLs & the weakness is extending upto C8-T1 level. But
there is no sensory loss.
So my DD are
1. Acute inflammmatory demyelinating polyneuropathy which is most likely to be GBS.
2. Chronic inflammmatory demyelinating polyneuropathy
3. Predominantly peripheral motor neuropathy
So to confirm my diagnosis, NCS, LP
& to support my diagnosis FBC
If having diarrhea or other infective features…..
Rx:
1. Ig
2. Plasmaparesis if IG not available
Mx
1. Monitoring & chart
a. Single breath count tds
b. Motor level tds
2. If rapid, send the pt to ICU
3. Check ETT & ambu
4. Cannulate: resp arrest
5. Notify
If you are to ask a single question from the pt what are you going to ask?
Temporal nature of disease & onset
Spastic paraparesis
1. Transverse myelitis→ MS
2. Trauma→ brown sequard
Ix:
Thoracic lumbar xray
Yapa Wijeratne
6. MRI-dorsal/ lumbar spine/ cauda equina
Stroke > CT
[Brain > CT, brainstem > MRI]
Foot drop
Ix:
Xray : neck of fibula #
Uss nerve
Peripheral nerve > nerve biopsy- sural
Muscle biopsy-gastrocnemius soleus (in a infant-vastus medius/lateralis)
Any radiculopathy
Xray AP/ lateral
EMG: denervation features
MRI of the area
NCS: NO USE. Usually normal.
