Injury Prevention & Rehabilitation Flashcards

During the return-to-sport continuum, which criterion is considered most predictive of re-injury risk for a quadriceps strain?

Answer: Limb symmetry index above 90% on strength testing

A limb symmetry index (LSI) above 90% on isokinetic or functional strength testing is widely used as a threshold before return to full sport activity.

Which ankle sprain type accounts for approximately 85% of all ankle sprains seen in athletes?

Answer: Lateral ankle sprain (ATFL/CFL complex)

Lateral ankle sprains involving the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) represent roughly 85% of all ankle sprains.

What does the acronym POLICE stand for in modern acute injury management?

Answer: Protection, Optimal Loading, Ice, Compression, Elevation

POLICE (Protection, Optimal Loading, Ice, Compression, Elevation) updated the older RICE protocol by emphasizing early optimal loading to promote healing.

Which training modality is most appropriate during the early phase of ACL rehabilitation (first 2 weeks post-surgery) to maintain cardiovascular fitness?

Answer: Pool walking or aqua jogging

Aqua jogging and pool walking allow cardiovascular conditioning while minimizing compressive and shear forces on the healing graft.

An athlete has chronic rotator cuff tendinopathy. Which exercise approach is best supported by current evidence for tendon remodeling?

Answer: Heavy slow resistance (HSR) training

Heavy slow resistance training stimulates collagen synthesis and tendon remodeling, outperforming rest or passive modalities in chronic tendinopathy.

What is the primary purpose of neuromuscular training in ACL injury prevention programs such as PEP or FIFA 11+?

Answer: Improve landing mechanics and dynamic knee stability

Neuromuscular training improves landing mechanics, reduces valgus collapse, and enhances dynamic knee stability, directly lowering ACL injury rates.

Which risk factor is most strongly associated with non-contact lower extremity injury in team-sport athletes?

Answer: High training monotony combined with acute training load spike

A rapid spike in acute training load relative to chronic training load (high acute:chronic workload ratio) combined with monotonous training significantly elevates injury risk.
