Question 1

A patient with total knee arthroplasty is at post-op day 3. Which ROM goal is standard for discharge from acute care?

Accepted Answer

0–90 degrees of knee flexion

Answer

Achieving 0–90 degrees of knee flexion is the typical acute care discharge criterion following total knee arthroplasty to ensure safe functional mobility.

Question 2

Which outcome measure is most appropriate for assessing functional limitations in a patient with shoulder impingement syndrome?

Accepted Answer

Shoulder Pain and Disability Index (SPADI)

Answer

The SPADI is a validated, region-specific outcome measure that assesses pain and functional disability related to shoulder conditions such as impingement.

Question 3

During gait retraining for a patient with chronic low back pain, which cue is most supported by evidence to reduce lumbar loads?

Accepted Answer

Increasing step rate (cadence) by 5–10%

Answer

Increasing step rate by 5–10% reduces peak hip adduction and trunk lateral lean, decreasing lumbar loading during gait in patients with chronic LBP.

Question 4

Which therapeutic ultrasound parameter produces the greatest thermal effect for treating subacute muscle spasm?

Accepted Answer

Continuous mode at 1 MHz, 1.5 W/cm²

Answer

Continuous mode maximizes thermal delivery; 1 MHz penetrates deeper tissues (3–5 cm), and 1.5 W/cm² provides sufficient intensity to raise tissue temperature therapeutically.

Question 5

A patient with a distal radius fracture is immobilized for 6 weeks. Which intervention addresses the most common secondary complication upon cast removal?

Accepted Answer

Active and passive ROM exercises for wrist, forearm, and digit mobility

Answer

After 6 weeks of immobilization, the most prevalent complication is joint stiffness; restoring ROM through active and passive exercises is the primary initial intervention.
