CCSP Rehabilitation & Therapeutic Exercise 2 — Questions and Answers
Question 1: Which phase of tissue healing is characterized by collagen remodeling and increased tensile strength?
- Inflammatory phase
- Proliferative phase
- Remodeling phase (Correct answer)
- Hemostasis phase
Correct answer: Remodeling phase
The remodeling phase (weeks 3–12+) involves type III collagen replacement by type I and progressive tensile strength gains.
Question 2: A chiropractic sports physician is prescribing eccentric hamstring exercises for a sprinter. Which protocol is most evidence-based for hamstring injury prevention?
- Nordic curl protocol (Correct answer)
- Leg press protocol
- Seated leg curl protocol
- Standing hip flexion protocol
Correct answer: Nordic curl protocol
The Nordic curl (prone knee flexion eccentric) protocol has the strongest evidence for reducing hamstring strain recurrence in sprinters.
Question 3: In shoulder rehabilitation, the 'empty can' exercise primarily targets which muscle?
- Infraspinatus
- Subscapularis
- Supraspinatus (Correct answer)
- Teres minor
Correct answer: Supraspinatus
The empty can (Jobe) test position — arm at 90° abduction, 30° forward flexion, internally rotated — maximally loads the supraspinatus.
Question 4: Which proprioceptive training progression is most appropriate immediately after acute ankle sprain?
- Single-leg balance on foam pad
- Double-leg balance on stable surface (Correct answer)
- Single-leg plyometric hops
- BOSU ball single-leg squats
Correct 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.
Question 5: Delayed onset muscle soreness (DOMS) typically peaks at what time after unaccustomed eccentric exercise?
- 2–6 hours
- 12–24 hours
- 24–72 hours (Correct answer)
- 96–120 hours
Correct answer: 24–72 hours
DOMS characteristically peaks 24–72 hours post-exercise due to inflammatory mediator accumulation and mechanical micro-damage resolution.
Question 6: For a swimmer with shoulder impingement, which scapular stabilization exercise is preferred in early rehabilitation?
- Overhead press
- Serratus anterior wall slide (Correct answer)
- Lat pulldown
- Upright row
Correct 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.
Question 7: The Functional Movement Screen (FMS) score threshold below which injury risk is considered elevated is:
- 21
- 17
- 14 (Correct answer)
- 10
Correct answer: 14
An FMS composite score ≤14 is associated with a significantly increased risk of musculoskeletal injury in active populations.
