Pulsed ultrasound on wound healing is described as having which action on open wounds?

• A. Excelled action of open wound healing
• B. Delayed closure
• C. No effect
• D. Increased infection risk

Answer: (A)

Pulsed ultrasound delivers low-energy, non-thermal mechanical energy that stimulates the cellular processes responsible for tissue repair. In open wounds, this energy enhances fibroblast activity and collagen synthesis, promotes angiogenesis, and supports epithelialization, while improving local blood flow. The pulsed (not continuous) approach minimizes heating and uses mechanisms like acoustic streaming to boost cell signaling and fluid movement, helping wound edges migrate and granulation tissue form. Together, these effects speed up wound closure and healing compared with no treatment, which is described as accelerated/open wound healing. It isn’t about delaying closure, having no effect, or increasing infection risk when used correctly.
