The Role of Ultrasound Therapy in the Management of Musculoskeletal Soft Tissue Pain.

Papadopoulos, Emmanuel S; Mani, Raj

Ultrasound is an invaluable physical modality widely used for diagnosis and therapy in humans and animals. It is noninvasive, atraumatic, and may be used repeatedly. As a therapeutic tool, ultrasound has been in use for some 6 decades. Therapeutic ultrasound (TUS) is used for the treatment of musculoskeletal disorders, including acute soft tissue injuries, overuse syndromes, as well as chronic orthopedic and rheumatologic conditions. The aim of this review was to investigate the clinical effectiveness of TUS in musculoskeletal acute and chronic pain, mainly through the control of inflammation and the promotion of soft tissue injury healing. Based on the evidence presented, TUS is clinically effective in some musculoskeletal soft tissue pain conditions, but due to conflicting results in some studies, no specific positive recommendations can be made, nor does it permit exclusion of TUS from clinical practice. In phonophoresis, TUS plays a significant role, without reported adverse effects. There is scope for improving the evidence base with better designed studies.
