Question 1

A distance runner presents with patellofemoral pain. Which hip strengthening focus shows the best evidence for reducing anterior knee pain?

Accepted Answer

Hip abductor and external rotator strengthening

Answer

Strengthening hip abductors and external rotators reduces dynamic valgus and patellofemoral contact stress, improving anterior knee pain in runners.

Question 2

Which type of muscle contraction produces the greatest force per unit cross-sectional area?

Accepted Answer

Eccentric

Answer

Eccentric contractions generate the greatest force per cross-sectional area due to passive titin contribution and cross-bridge mechanics.

Question 3

Aquatic therapy is introduced in early ACL rehabilitation primarily because:

Accepted Answer

Buoyancy reduces joint compressive loads

Answer

Buoyancy offloads body weight, reducing tibiofemoral compressive forces and allowing early weight-bearing exercise before full weight-bearing tolerance.

Question 4

In the Cyriax model of selective tissue tension, which finding indicates a contractile tissue lesion?

Accepted Answer

Pain and/or weakness on resisted isometric testing

Answer

Cyriax defined contractile lesions (muscle, tendon, attachment) by pain and/or weakness during resisted isometric testing with passive motion unaffected.

Question 5

Which closed kinetic chain exercise is most appropriate for early tibial stress fracture return-to-run progression?

Accepted Answer

Double-leg mini squat progressing to step-ups

Answer

A graded progression from double-leg mini squats to step-ups incrementally loads the tibia without the high-impact forces of jumping or running.
