Physical Examination Flashcards
What are the basics of the OSCE physical exam?
- Performed on a role player who does NOT have any real signs and will not act them out
- Explain every step as you do it in order to show what you are looking for, what the findings would look like and the potential DDx
- Relevant clinical findings will be provided to you by the examiner as you go, these will not be given to you if you haven’t performed that part of the exam
- Make sure to highlight the aspects of the exam that will differentiate key diagnoses
- it can be helpful to provide an opening statement to summarise differentials and what you will examine for
- The examination is looking at DDx, severity, precipitants (ie allergy) and complications

Bilateral lower limb weakness exam
DDx
- Guillane-Barre Syndrome!!!
- Acute trauma (including cauda equina)
- Spinal infection
- Tick Paralysis
- Endocrine complication (Diabetes, hyperthyroid etc)
Exam
- General inspection for wasting, dyspnoea and flat facies
- Focussed spinal exam (trauma and infection)
- Abdominal exam particularly for enlarged bladder and PVR
- Lower limb neuro exam targeting sensation, power and reflexes (reduced/absent in GBS)
- Perianal sensation and anal tone (cauda equina)
- Consider upper limb and cranial nerves exam, as well as resp function tests
Investigations
GBS- LP for oligoclonal bands and albuminocytolic dissociation
- Forced vital capactiy (<20ml/kg suggestive of need for ICU
- Blood tests for antibodies and basic biochem
- consider ABG
- Consider viral PCR and stool cultures for caustive agent
What are the differences between upper motor and lower motor neurone disorders on exam?
Foot drop differentials
- Spinal cord vs radiculopathy vs peripheral nerve
- Spinal cord = upper motor neurone signs, dermatomal sensory alteration
- Radiculopathy = lower motor neurone signs and dermatomal sensory alteration
- Peripheral nerve (common or deep peroneal) = LMN and nerve distribution sensory changes
Common peroneal
- Anterior stocking distribution (deep and superfical peroneal), proximal and lateral aspect of lower leg compression or injury
Deep Peroneal
- 1st webspace sensory distribution, usually from anterior lower leg compartment syndrome
What is the approach to the swollen joint/Arthritis?
Back pain examination
Look
- Deformity (both back and side)
- Loss of lumbar lordosis, obvious scoliosis
- Previous surgeries
- Erythema, swelling, bruising
Feel
- Central spine for tenderness
- Paraspinal for muscle spasm and tenderness
- Bogginess/deformity
- Push on bilateral ASIS to move the SI joints, illicits SI pain if the issue
Move
- All active
- Bend forward to touch toes
- Bend side to side
- Bend backwards
- Sit down (stabilises the hips) and test lateral rotation
Special tests
- Lower limb neuro exam
- Straight leg raise (lying down, lift straightened leg to point of pain then stop, compare to other side)
- Lasgues test (with straight leg raised, dorsiflex the ankle, should increase pain/symptoms, suggestive of neurological cause ie disc herniation)
General Investigations
- Xrays/CT/MRI
General Management
- Analgesia
