Therapeutic ultrasound is a treatment modality commonly used in physical therapy to provide deep heating to soft tissues in the body. These include muscles, tendons, joints, and ligaments. Non-thermal, pulsed ultrasound can be used to facilitate tissue healing, modify inflammation, and enhance transdermal drug delivery.
Therapeutic ultrasound works by using heated sound waves and applying the energy to joints and soft tissues. The waves then massage soft tissues, in most cases, painlessly to encourage stimulation and thus, healing the affected areas.
