Question 1

A patient demonstrates difficulty walking on heels and foot drop. Which nerve root level is most likely affected?

Accepted Answer

L5

Answer

L5 nerve root innervates the tibialis anterior and extensor hallucis longus; an L5 lesion causes dorsiflexion weakness and foot drop.

Question 2

Which stage of Brunnstrom's Motor Recovery Scale describes the appearance of spasticity and stereotyped limb synergies in a stroke patient?

Accepted Answer

Stage 2

Answer

Stage 2 of Brunnstrom's recovery is characterized by the onset of spasticity and the emergence of limb synergy patterns following a flaccid Stage 1.

Question 3

A patient is referred for vestibular rehabilitation with complaints of position-triggered brief vertigo. The Dix-Hallpike test reproduces symptoms with upbeat-torsional nystagmus. Which canal is most likely involved?

Accepted Answer

Posterior semicircular canal

Answer

Upbeat-torsional nystagmus on Dix-Hallpike testing is pathognomonic for posterior semicircular canal BPPV, the most common form.

Question 4

Which pharmacological agent used in the treatment of hypertension can cause exercise-induced hypotension and blunt the heart rate response to exercise?

Accepted Answer

Beta-blockers

Answer

Beta-blockers blunt sympathetic-mediated heart rate increase and can cause exertional hypotension, requiring rate of perceived exertion (RPE) rather than heart rate for exercise intensity monitoring.

Question 5

When measuring passive knee extension with a goniometer, the stationary arm of the goniometer should align with which landmark?

Accepted Answer

Greater trochanter to lateral femoral condyle

Answer

For knee extension ROM, the stationary arm aligns along the femur from the greater trochanter to the lateral femoral condyle, with the axis at the lateral femoral condyle.
