Continuous ultrasound on injury response process tends to do what?

Continuous ultrasound on injury response process tends to do what?

• A. Accelerate the inflammatory response
• B. Slow the healing process
• C. Cause immediate necrosis
• D. Do not affect inflammation

Answer: (A)

Continuous ultrasound delivers energy continuously, heating the tissue. That heating increases metabolic activity and promotes vasodilation, which boosts blood flow and brings more immune cells and inflammatory mediators to the injured area. Because of this, the inflammatory response is amplified, or accelerated, compared with not using the modality or using non-thermal options. In practice, this means continuous ultrasound can enhance the inflammatory process by increasing tissue temperature and perfusion, which is why the best answer is that it tends to accelerate the inflammatory response. It’s worth noting that this heating effect is why clinicians often avoid continuous ultrasound in very acute injuries where excessive inflammation is undesirable, and may prefer pulsed or non-thermal ultrasound in those cases.
