Pulsed ultrasound on wound healing has what effect on open wounds?

• A. Accelerated healing
• B. Slower healing
• C. No effect
• D. Increased scar formation

Answer: (A)

Pulsed ultrasound delivers non-thermal mechanical energy that stimulates the body's repair processes. Using a pulsed (low-duty-cycle) approach minimizes heating and instead enhances cellular activity in the wound bed. In open wounds this mechanical stimulation boosts fibroblast activity and collagen production, promotes granulation tissue formation, and accelerates epithelialization and new blood vessel growth. Together, these effects speed up wound closure, making healing faster rather than slower or unchanged; scar outcomes can vary, but the primary effect described here is accelerated healing.
