Injury Prevention & Rehabilitation Flashcards

Which screening tool uses single-leg squat depth, trunk lean, and knee position to assess dynamic lower extremity alignment?

Answer: Single-leg squat assessment

The single-leg squat assessment evaluates dynamic knee valgus, trunk lean, and hip control, which are linked to lower extremity injury risk.

A volleyball player develops medial tibial stress syndrome (shin splints). Which training modification is the FIRST priority?

Answer: Switch to aquatic or low-impact cross-training

Reducing or eliminating repetitive impact loading through cross-training is the first step to allow bone and periosteum to recover from medial tibial stress syndrome.

What is the recommended approach when a concussed athlete has been symptom-free for 24 hours and wants to return to play?

Answer: Begin a stepwise return-to-play protocol starting with light aerobic exercise

A graded return-to-play protocol beginning with light aerobic activity and progressing over at least 24 hours per step is required before full contact is permitted.

Which of the following best describes the concept of tissue tolerance in injury prevention?

Answer: The capacity of a tissue to withstand applied load without failure

Tissue tolerance refers to a structure's ability to withstand mechanical load; injuries occur when applied load exceeds this threshold.

An athlete is in the remodeling phase of healing (6 weeks+). Which type of exercise best promotes proper collagen fiber alignment?

Answer: Progressive functional loading in the direction of tissue stress

Controlled, progressive loading aligned with normal tissue stress patterns stimulates collagen fibers to remodel along functional lines of force.

Which hip strengthening exercise is most specific for preventing iliotibial band syndrome in runners?

Answer: Standing hip abduction with resistance band

Hip abductor strengthening, particularly gluteus medius exercises like banded hip abduction, reduces hip drop and lateral knee stress that cause IT band syndrome.

Which psychological factor is a recognized barrier to successful return to sport after major injury?

Answer: Fear of re-injury (kinesiophobia)

Kinesiophobia (fear of re-injury) is one of the strongest psychological predictors of poor return-to-sport outcomes and must be addressed in rehabilitation.
