Question 1

Which stretching modality produces the greatest acute gain in range of motion when applied immediately before athletic performance?

Accepted Answer

PNF contract-relax stretching

Answer

PNF contract-relax produces the greatest acute ROM gains by maximally inhibiting the target muscle via autogenic inhibition, though dynamic stretching is preferred pre-competition.

Question 2

During ACL rehabilitation, the 'safe zone' for open kinetic chain knee extension exercises to minimize anterior tibial shear is:

Accepted Answer

60–90° of knee flexion

Answer

Open kinetic chain knee extension from 60–90° places minimal strain on the ACL graft because the hamstrings co-contract effectively at greater flexion angles.

Question 3

Which criterion is used in the Single-Leg Hop for Distance test to determine return-to-sport readiness after lower extremity injury?

Accepted Answer

Limb symmetry index ≥90%

Answer

A limb symmetry index (LSI) ≥90% on the single-leg hop for distance is the standard criterion for safe return-to-sport consideration.

Question 4

Tendinopathy management using heavy slow resistance (HSR) training is distinguished from classic eccentric-only protocols by:

Accepted Answer

Including both concentric and eccentric phases at slow tempo

Answer

HSR training uses full concentric-eccentric cycles at slow tempo (3-0-3) and heavy loads, showing equal or superior outcomes to eccentric-only protocols for patellar tendinopathy.

Question 5

The primary goal of the stabilization phase in a three-phase rehabilitation model is:

Accepted Answer

Re-establishing neuromuscular control and joint proprioception

Answer

The stabilization phase focuses on restoring neuromuscular control, proprioception, and postural stability before progressing to strengthening and sport-specific phases.
