Ultrasound stimulation is a therapeutic technique that uses sound waves to promote healing and tissue repair. It involves applying high-frequency sound waves to the body, which can penetrate deep into tissues. This process can help reduce pain, improve circulation, and enhance the healing of injuries. The treatment is commonly used in physical therapy and rehabilitation settings. Ultrasound machines generate the sound waves, which are delivered through a handheld device that moves over the skin. The procedure is generally painless and can be beneficial for conditions like muscle strains, joint pain, and soft tissue injuries.
