NPTE-PT Musculoskeletal System Examination 5

Question 1

A patient presents with a positive Thompson test (no plantar flexion with calf squeeze). This indicates rupture of which structure?

Accepted Answer

Achilles tendon

Answer

The Thompson test assesses Achilles tendon continuity; absence of plantar flexion when the calf is squeezed indicates a complete Achilles tendon rupture.

Question 2

Which of the following describes the Cyriax concept of a 'non-capsular pattern' of restriction?

Accepted Answer

Limitation of only one or two movements not following capsular ratio

Answer

A non-capsular pattern involves restriction of one or two movements not in the proportions expected for capsular involvement, suggesting ligament adhesion, loose body, or extra-articular pathology.

Question 3

A patient has decreased sensation on the medial forearm and weak elbow flexion after a humeral fracture. Which nerve is most likely injured?

Accepted Answer

Musculocutaneous nerve

Answer

The musculocutaneous nerve innervates the biceps and coracobrachialis (elbow flexion/supination) and provides sensation to the lateral forearm via the lateral antebrachial cutaneous nerve — medial forearm loss suggests this nerve.

Question 4

When using a goniometer to measure knee flexion in prone, the stationary arm is aligned with:

Accepted Answer

The lateral femur parallel to the femoral shaft

Answer

For knee flexion, the stationary arm follows the lateral femoral shaft (toward the greater trochanter), and the moving arm follows the fibular shaft toward the lateral malleolus.

Question 5

A positive Apley compression test combined with a negative Apley distraction test at the knee indicates pathology of which structure?

Accepted Answer

Menisci

Answer

Apley compression loads the menisci between the femur and tibia (positive = meniscal pain), while distraction unloads the menisci but stresses the ligaments.
