Ultrasound therapy is electrotherapy which has been used in physiotherapy practices for many years. It is mainly used for its non-thermal effect where high-frequency sound waves cause vibrations and movement of cellular fluids. Proposed benefits of ultrasound therapy include improving the healing rate of certain soft tissues. It is hypothesized to Increase blood flow to an area in order to accelerate the resolution time of the inflammatory process. Stimulate the production of collagen (the main protein in tendons and ligaments) during tissue healing.
