Which statement best describes the overall effect of ultrasound on inflammation and healing according to the material?

• A. Ultrasound can accelerate healing by promoting proliferation and collagen synthesis
• B. Ultrasound always worsens inflammation
• C. Ultrasound has no effect on healing
• D. Ultrasound only affects pain perception

Answer: (A)

Therapeutic ultrasound speeds up the healing process by stimulating the cellular activities that drive tissue repair. The mechanical and thermal effects of ultrasound can boost fibroblast activity and collagen synthesis, which strengthens and remodels the injured tissue. Even when used in pulsed (non-thermal) modes, ultrasound can promote cell signaling, protein synthesis, and microvascular changes that support regeneration. This is why the overall effect on inflammation and healing is to accelerate repair rather than simply reduce symptoms. The other statements don’t fit because ultrasound does not always worsen inflammation, and it has notable effects beyond pain modulation. It also influences healing processes, not just pain perception.
