Therapeutic ultrasound uses high-frequency sound waves to deliver energy beneath the skin and into targeted soft tissues. Unlike the ultrasound used to produce diagnostic images, this form of ultrasound is used as a treatment for certain muscle, tendon, ligament, and soft tissue problems.

Chiropractors may use therapeutic ultrasound alongside adjustments, stretching, and rehabilitation when treating an injury or area of discomfort. The treatment is non-invasive and can be focused directly on the affected area. Depending on the condition, ultrasound may be one part of a larger treatment plan aimed at supporting recovery and restoring comfortable movement.
