Question 1

A physical therapist is applying ultrasound over a recent scar tissue formation. Which parameter is MOST appropriate to promote tissue extensibility?

Accepted Answer

3 MHz, continuous, moderate intensity (1.0–1.5 W/cm²)

Answer

3 MHz continuous ultrasound heats superficial tissue (1–2 cm depth) most effectively, and moderate intensity in continuous mode increases collagen extensibility.

Question 2

Which exercise is considered CLOSED kinetic chain for the lower extremity?

Accepted Answer

Wall squat (wall slide)

Answer

A wall squat is a closed kinetic chain exercise because the foot remains in contact with a fixed surface, causing simultaneous multi-joint motion under load.

Question 3

A patient with adhesive capsulitis (frozen shoulder) in the freezing phase is best managed with which intervention priority?

Accepted Answer

Pain management and gentle ROM within pain-free range

Answer

In the freezing phase, pain is the dominant symptom; management focuses on pain control and gentle pain-free ROM to avoid exacerbating the inflammatory process.

Question 4

Which grade of joint mobilization is used primarily to reduce pain with minimal tissue stretch?

Accepted Answer

Grade I

Answer

Grade I mobilizations are small-amplitude oscillations at the beginning of range used primarily for pain modulation via neurophysiological mechanisms.

Question 5

A patient recovering from a hamstring strain (grade II) is progressing to sport-specific training. Which criterion BEST indicates readiness to advance?

Accepted Answer

Hamstring strength ≥90% of the uninvolved side with no pain during eccentric loading

Answer

Return to sport requires hamstring strength symmetry (≥90%) and pain-free eccentric loading to reduce re-injury risk during high-speed running.
