Wound healing is enhanced with which ultrasound modality?

Wound healing is enhanced with which ultrasound modality?

• A. High-intensity, continuous ultrasound.
• B. Low-intensity, pulsed ultrasound.
• C. Ultrasound has no effect on wound healing.
• D. Ultrasound is contraindicated for wounds.

Answer: (B)

Low-intensity pulsed ultrasound enhances wound healing because its mechanical, non-thermal energy stimulates cellular activities essential for repair. The pulsed, low-energy delivery avoids heating the tissue, reducing the risk of damaging new tissue, while promoting fibroblast activity, collagen synthesis, angiogenesis, and improved edema resolution. This combination speeds up the wound healing process and supports tissue regeneration. High-intensity continuous ultrasound relies on heating tissue to produce effects, which can cause thermal damage or delay healing, so it’s not used to promote wound repair. Saying ultrasound has no effect ignores the evidence that appropriate low-intensity pulsed ultrasound can aid healing. Claiming ultrasound is contraindicated for wounds is too absolute; with proper parameters and precautions, it can be beneficial for certain wounds.
