Which condition has strong evidence for continuous US treatment?

Which condition has strong evidence for continuous US treatment?

• A. Myofascial pain and trigger points
• B. Low back pain
• C. Carpal tunnel syndrome
• D. Pain from arthritis

Answer: (A)

Continuous ultrasound provides a thermal effect that helps relax muscle tissue and reduce tightness, making it particularly helpful for soft tissue problems where muscle hypertonicity is a key driver of pain. In myofascial pain and trigger points, heating the affected muscle bands can soften the taut bands, decrease local tenderness, improve blood flow, and lessen irritability of the trigger points. This combination of physiological effects aligns with observed clinical improvements in pain and range of motion, which is why the evidence supporting continuous US is strongest for myofascial pain and trigger points. For low back pain, carpal tunnel syndrome, or arthritis, the body of evidence is more inconsistent or shows only small or unclear benefits from continuous ultrasound, so they don’t have as robust support.
