超聲波是常用的物理療法，治療用途的超聲可以産生深入身體組織的高溫，以幫助結締組織愈合、緩解肌肉痙攣、改善關節攣縮和腫脹。超聲還能夠增加局部血流，可以幫助身體減少局部腫脹和慢性炎症。研究表明，超聲對于骨折愈合也具有積極的治療作用。  超聲治療常見的适應症包括軟組織損傷，如肌腱炎，非急性關節腫脹和肌肉痙攣。大多數肌肉和韌帶損傷可以從超聲波治療中受益。

Therapeutic   ultrasound produces a deep heat to aid in the healing of connective tissues   and the reduction of muscle spasms, joint contractures and swelling. The   increase in local blood flow helps reduce local swelling and chronic   inflammation, and  promote bone   fracture healing and scar tissue breakdown. The common conditions   treated with ultrasound include soft tissue injuries such as tendonitis,   joint pain, ligament sprains and muscle spasm.
