Rehabilitation & Therapeutic Exercise Flashcards

Which phase of tissue healing is characterized by collagen remodeling and increased tensile strength?

Answer: Remodeling phase

The remodeling phase (weeks 3–12+) involves type III collagen replacement by type I and progressive tensile strength gains.

A chiropractic sports physician is prescribing eccentric hamstring exercises for a sprinter. Which protocol is most evidence-based for hamstring injury prevention?

Answer: Nordic curl protocol

The Nordic curl (prone knee flexion eccentric) protocol has the strongest evidence for reducing hamstring strain recurrence in sprinters.

In shoulder rehabilitation, the 'empty can' exercise primarily targets which muscle?

Answer: Supraspinatus

The empty can (Jobe) test position — arm at 90° abduction, 30° forward flexion, internally rotated — maximally loads the supraspinatus.

Which proprioceptive training progression is most appropriate immediately after acute ankle sprain?

Answer: Double-leg balance on stable surface

Double-leg balance on a stable surface is the safest entry point early after ankle sprain before progressing to unstable or single-leg tasks.

Delayed onset muscle soreness (DOMS) typically peaks at what time after unaccustomed eccentric exercise?

Answer: 24–72 hours

DOMS characteristically peaks 24–72 hours post-exercise due to inflammatory mediator accumulation and mechanical micro-damage resolution.

For a swimmer with shoulder impingement, which scapular stabilization exercise is preferred in early rehabilitation?

Answer: Serratus anterior wall slide

The serratus anterior wall slide promotes upward scapular rotation and reduces subacromial space compression, making it ideal early in impingement rehab.

The Functional Movement Screen (FMS) score threshold below which injury risk is considered elevated is:

Answer: 14

An FMS composite score ≤14 is associated with a significantly increased risk of musculoskeletal injury in active populations.
