Ultrasound therapy is a non-invasive therapeutic modality widely used in physical therapy and rehabilitation to treat musculoskeletal injuries, reduce pain, and enhance the healing process. By utilizing sound waves at high frequencies, ultrasound therapy delivers mechanical energy to tissues, promoting cellular activity and improving circulation. This technique has become a cornerstone in modern physiotherapy due to its versatility, safety, and effectiveness. Ultrasound therapy employs sound waves generated by a handheld device called a transducer. This device produces high-frequency sound waves (typically between 1 and 3 MHz) that penetrate the skin and underlying tissues.
