A client is 6 weeks past a hamstring strain and her physician has cleared her for massage. The massage therapist applies cross-fiber friction followed by gentle, progressive stretching to the healed area. Which BEST explains the purpose of this approach at this stage?
Show answer & explanation
Answer: B
- Six weeks after a strain places the tissue in the remodeling (maturation) phase.
- Collagen laid down in the repair phase is disorganized; loading at this stage guides fibers to align with the lines of tension.
- So friction plus gentle stretch aims to organize the scar, not to remove or reverse it.
Replaces the scar collagen with new muscle fiber: Muscle heals largely by scar formation; massage cannot convert collagen scar back into contractile muscle fiber.
Helps new collagen align with lines of stress: Correct. At about 6 weeks the tissue is in the remodeling (maturation) phase; collagen laid down in a disorganized pattern during repair is reorganized, and gentle mechanical loading guides the fibers to align with the lines of tension, improving pliability and function.
Stops further collagen production: Collagen production and turnover continue through remodeling; the aim is to organize the new collagen, not to stop it.
Increases random collagen cross-linking: Random cross-links are what form restrictive adhesions; friction and stretch aim to reduce them, not add more.
In remodeling, appropriate loading (friction, gentle stretch, movement) helps collagen align with lines of stress.
