Answer

A complete fracture resulting from a single high-impact collision

Answer

A fracture at a growth plate in skeletally immature athletes

Question 4

Which rehabilitation approach is most evidence-supported for reducing hamstring strain re-injury rates?

Accepted Answer

Progressive eccentric loading exercises such as the Nordic hamstring curl

Answer

Complete rest until pain-free, then immediate return to full sprint training

Answer

Ultrasound therapy applied daily for six weeks

Answer

Passive static stretching of the hamstrings twice daily

Question 5

A standard objective criterion for return-to-play after ACL reconstruction is that the injured limb achieves what level of symmetry compared to the uninvolved limb on functional tests?

Accepted Answer

90% limb symmetry index

Answer

70% limb symmetry index

Answer

80% limb symmetry index

Answer

100% limb symmetry index with zero pain

Question 6

Which common running injury is characterized by sharp heel pain that is typically worst during the first steps after waking or after prolonged sitting?

Accepted Answer

Plantar fasciitis

Answer

Achilles tendinopathy

Answer

Morton's neuroma

Answer

Peroneal tendinosis

Question 7

In the acute phase of a musculoskeletal injury (0–72 hours), how does cryotherapy (ice application) reduce swelling and pain?

Accepted Answer

By causing vasoconstriction that limits secondary tissue damage and activates pain-gate mechanisms

Answer

By increasing local blood flow to flush out inflammatory mediators

Answer

By permanently destroying pain nerve endings in the area

Answer

By stimulating collagen synthesis to begin repair immediately
