What ultrasound parameter is associated with increasing the breaking strength of a healing incision when used continuously?

• A. Frequency of 1-1.5 MHz for 5 minutes daily
• B. Duration of 15 minutes daily at 3 MHz
• C. Frequency of 0.5-0.75 MHz for 2 minutes
• D. Frequency of 2-3 MHz for 7 minutes

Answer: (A)

Continuous ultrasound heats tissue, and this thermal effect can accelerate the healing process by boosting collagen production and cross-linking, which strengthens the scar. For a healing incision, you want a depth that reaches the wound area without overheating deeper structures, plus a duration that delivers a safe, effective heating dose. A frequency of about 1–1.5 MHz penetrates to the superficial-to-mid tissue where an incision lies, providing the right balance of heating without excessive surface concentration. Five minutes of treatment daily gives enough energy to raise tissue temperature to a therapeutic range and support ongoing remodeling, making the incision stronger over time. Higher frequencies heat only very superficially or require longer exposure, and lower frequencies with short durations may not heat the wound area adequately.
