Question 1

During the inflammatory phase of tissue healing, which cells are primarily responsible for phagocytosis and debris removal?

Accepted Answer

Macrophages

Answer

Macrophages are the primary phagocytic cells during the inflammatory phase. They remove cellular debris, dead tissue, and pathogens while also releasing growth factors that initiate the proliferative phase of healing.

Question 2

When designing a rehabilitation program for a post-operative rotator cuff repair, which exercise would be most appropriate during the first two weeks?

Accepted Answer

Passive range of motion performed by the athletic trainer

Answer

During the initial protective phase after rotator cuff repair (weeks 0-6), only passive range of motion is appropriate to prevent adhesions and maintain joint mobility without stressing the healing surgical repair.

Question 3

What is the primary goal of the proliferative phase of wound healing as it relates to rehabilitation?

Accepted Answer

Collagen deposition and scar tissue formation

Answer

The proliferative phase (days 3-21) is characterized by fibroblast activity producing collagen to fill the wound defect. Scar tissue formation provides initial structural integrity but lacks the organization and strength of the original tissue.

Question 4

An athletic trainer is progressing an athlete's ACL rehabilitation. Which functional test should be used to assess readiness for return to sport?

Accepted Answer

Single-leg hop for distance with limb symmetry index

Answer

The single-leg hop for distance test (with limb symmetry index calculation) is a validated functional test for ACL rehabilitation. An LSI of at least 90% (injured vs. uninvolved limb) is generally required for return to sport.

Question 5

Which principle of rehabilitation states that exercises should progress from simple to complex and from stable to unstable surfaces?

Accepted Answer

Principle of functional progression

Answer

Functional progression dictates that rehabilitation should advance through a systematic sequence of activities that progressively challenge the healing tissue and neuromuscular system, moving from simple to complex tasks.
