Ultrasound therapy is a medical treatment that uses sound waves to promote healing in tissues. It works by sending high-frequency sound waves into the body, which can help reduce pain, improve circulation, and accelerate tissue repair. This non-invasive technique is often used in physical therapy for conditions like muscle strains, joint pain, and inflammation. During a typical session, a therapist applies a gel to the skin and moves a handheld device over the affected area. The sound waves penetrate the skin, creating a gentle heat that can enhance blood flow and stimulate cell activity, aiding in recovery and rehabilitation.
