Therapeutic ultrasound is a form of deep heat therapy created by sound waves. When applied to soft tissues and joints, the sound waves are a form of micro-massage that help reduce swelling, increase blood flow, and decrease pain, stiffness, and spasms. Ultrasound therapy is the use of high frequency sound waves to penetrate the skin to stimulate the cells and tissues where external treatments can not reach. Therapists have been using ultrasound for many years to treat conditions and injuries such as tendon and muscle injuries, arthritis, joint pain, muscle aches, strains, and more.
Medical sonography (ultrasonography) is an ultrasound-based diagnostic medical imaging technique used to visualize muscles, tendons, and many internal organs, to capture their size, structure and any pathological lesions with real time tomographic images. Ultrasound can be used to determine soft-tissue injury such as nerve damage, ganglions (tumors growing on a tendon) or other superficial injuries. Sports medicine has also benefited from ultrasound, such as the examination of sports-related injuries like stressed ligaments in the knee or an injured rotator cuff (shoulder).
