Question 1

A physical therapist is testing a patient's deep tendon reflexes and finds an absent patellar reflex with weakness in knee extension. Which nerve root level is most likely involved?

Accepted Answer

L4

Answer

The patellar (knee-jerk) reflex is mediated primarily by the L4 nerve root. Absence of this reflex combined with knee extension weakness points to L4 pathology, as the quadriceps muscle group is innervated chiefly at L3-L4 but the reflex arc centers on L4.

Question 2

During the stance phase of gait, which muscle group is primarily responsible for preventing the knee from buckling into flexion at initial contact and loading response?

Accepted Answer

Quadriceps

Answer

The quadriceps eccentrically contract during loading response to control knee flexion and prevent buckling. They absorb the impact of body weight and stabilize the knee as the limb accepts load.

Question 3

A therapist performing a Spurling's test applies downward compression and lateral flexion of the cervical spine toward the symptomatic side. A positive test is indicated by:

Accepted Answer

Reproduction of radicular symptoms into the ipsilateral arm

Answer

Spurling's test is positive when the maneuver reproduces radicular (nerve root) symptoms — pain, numbness, or tingling — radiating into the ipsilateral arm. Local neck pain alone does not constitute a positive finding for foraminal compression.

Question 4

A patient with adhesive capsulitis (frozen shoulder) would most likely demonstrate the greatest loss of passive range of motion in which movement?

Accepted Answer

External rotation

Answer

External rotation is characteristically the most restricted motion in adhesive capsulitis because the anterior capsule and coracohumeral ligament become contracted. The pattern of restriction follows a capsular pattern: external rotation > abduction > internal rotation.

Question 5

When measuring blood pressure in a patient with suspected coarctation of the aorta, the physical therapist should compare readings between:

Accepted Answer

Upper extremity and lower extremity

Answer

Coarctation of the aorta causes a significant blood pressure gradient between the upper and lower extremities, with higher pressures in the arms and reduced or absent pressure in the legs. Comparing upper to lower extremity BPs is the key clinical screen.
