Continuous ultrasound effect on tissue healing includes which outcome?

• A. Increase rate of collagen synthesis and tissue strength of tendons
• B. Decrease rate of collagen synthesis
• C. Inhibit fibroblasts
• D. Increase scar tissue only

Answer: (A)

Continuous ultrasound delivers energy steadily, producing thermal effects that raise tissue temperature and boost healing activity. This heating stimulates fibroblasts to synthesize collagen more rapidly and promotes proper collagen remodeling, which strengthens tendon tissue. In healing tendons, that combination—faster collagen production and increased tissue strength—best describes the observed outcome of continuous ultrasound. It does not primarily decrease collagen synthesis, inhibit fibroblasts, or create scar tissue alone, since the heating effect accelerates the normal healing processes rather than suppressing them or restricting them to scar formation.
