distal (characteristic of periph. neuropathy), *Right vs. Left, upper limbs, lower limbs, nerve root distribution, nerve distribution, severity(0 to 5), pain effect, other.
![Page 18: Neurology Review 2015](https://reader036.vdocuments.mx/reader036/viewer/2022070403/563db807550346aa9a8fdc9b/html5/thumbnails/18.jpg)
MOTOR EXAMINATION
• RIGIDITY, SPASTICITY, OTHER
• SPEED OF MOVEMENT
• ABNORMAL INVOLUNTARY MOVEMENTS – eg tremor
• OTHER ABNORMAL MOVEMENTS – eg epileptiform.
![Page 19: Neurology Review 2015](https://reader036.vdocuments.mx/reader036/viewer/2022070403/563db807550346aa9a8fdc9b/html5/thumbnails/19.jpg)
COORDINATIONCerebellar function
• Reason for doing the strength test before coordination is to know if incoordination is due only to muscle weakness
• May apparently vary with strength
![Page 20: Neurology Review 2015](https://reader036.vdocuments.mx/reader036/viewer/2022070403/563db807550346aa9a8fdc9b/html5/thumbnails/20.jpg)

• RAPIDLY ALTERNATING MOVEMENTSRAPIDLY ALTERNATING MOVEMENTS::– supination/pronation, tapping rhythm
• **HEEL/SHIN testHEEL/SHIN test::– proximal, transit– ankle dorsiflexion
• **TANDEM WALKINGTANDEM WALKING:: (?mechanical impediment)– A little difficult in fat persons and mechanically impaired
• CHECK / REBOUNDCHECK / REBOUND:**:** – Cerebellar test…person with disfunction will have more rebound
• POSTUREPOSTURE• STANDING BASESTANDING BASE:: width, stability• GAITGAIT:: stable, asymmetric, ?type
