Continuous ultrasound effect on wound healing includes which outcome?

• A. Increase rate of collagen synthesis and tissue strength of tendons
• B. Decrease rate of collagen synthesis
• C. Delay wound closure
• D. Inhibit capillary growth

Answer: (A)

Continuous ultrasound accelerates wound healing by boosting cellular activity in the repair tissue, especially increasing fibroblast metabolism and collagen production. As fibroblasts lay down new collagen and the collagen fibers mature and cross-link, the repaired tissue becomes stronger. This leads to an increased rate of collagen synthesis and greater tissue strength, which is especially relevant in connective tissues like tendons. The other possibilities—decreasing collagen production, delaying wound closure, or inhibiting capillary growth—do not align with how therapeutic ultrasound supports healing; in fact, ultrasound can enhance blood flow and capillary formation to supply nutrients for repair.
