What is the reported effect of continuous ultrasound on the injury response process?

• A. Excelleration of inflammatory response
• B. Suppression of inflammation
• C. No effect
• D. Immediate scar formation

Answer: (A)

Continuous ultrasound delivers steady acoustic energy that heats the tissue. This heating increases blood flow and metabolic activity in the treated area, which can accelerate the activities of the inflammatory phase—more inflammatory mediators and immune cells reach the injury site. In the short term, this can heighten swelling and inflammation, but it reflects the thermally driven response that ultrasound can induce. So the reported effect is an acceleration of the inflammatory response. The other options don’t fit with the thermal action of continuous ultrasound: it’s not typically used to suppress inflammation, it does have an effect rather than none, and it doesn’t cause immediate scar formation.
