51
Dorsal column (light touch) exam technique
Use a cotton wisp
Apply gentle touch
Ask pt to close eyes and report “yes” every time they perceive the stimulus
52
Pain (lateral spinothalamic tract) exam technique
Use disposable pin
Ask pt to Close their eyes and report whether they feel sharp or dull
Apply the short stimulus to all sites since if only the dull stimulus is applied, pain sensation has not been assessed.
53
Temperature (lateral spinothalamic tract_ exam technique
Use cold vibration fork
Ask pt if the perceive fork as cold.
54
Vibration sense exam technique
Use 128 hertz vibration fork
Apply stimulus over distal phalanx of index finger or large toe
Ask pt to report whether they feel vibration sense and then to report when it stops in order to assess the minimal threshold to perceive the stimulus.
Compare to your own extremities
55
Position sense exam technique
Demonstrate to the pt initially w/ eyes open that you will be moving their digit up or down
Ask pt to close eyes
Stabilize distal interphalangeal joint of the upper extremity and make minimal movements upwards or downwards and ask pt to report after each movement the direction.
Similarly in lower extremities, stabilize the interphalangeal joint and move large toe up or down.
56
Coordination (spinocerebellar tract) exam technique — upper extremities
Finger to nose
Rapid index to thumb movements or individual digits to thumb, rapid small index finger sircles over the opposite dorsal webspace, rapidly alternate each hand palmer then dorsal aspect down over thigh or opposite hand
57
Coordination (spinocerebellar tract) exam tech for lower extremities
