When should ultrasound treatment ideally begin after injury?

• A. Immediately after injury
• B. Two weeks after injury during the proliferative phase
• C. Six weeks after injury
• D. Only after surgical repair

Answer: (B)

Ultrasound helps healing by stimulating fibroblast activity, collagen synthesis, and new blood vessel growth, which are most active during the proliferative (repair) phase. Beginning ultrasound around two weeks after injury targets this phase, when new tissue is being laid down and tissue remodeling is starting, so the therapy can accelerate repair and improve tissue quality without overly disturbing the initial inflammatory response. Starting right after injury can keep you in the inflammatory stage where edema and inflammation are high, and ultrasound—especially continuous modes—can potentially worsen those processes. Waiting until six weeks moves you into the later remodeling phase when the immediate gains from ultrasound are diminished, so you miss the optimal window for accelerating repair. Using ultrasound only after surgical repair is context-specific and not the standard timing unless surgery dictates it.
