As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to reduce swelling and pain, reduce muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that pulls blood into the area in order to enhance the healing process.
Ultrasound is applied gently with a handheld soundhead, using strokes or circles over the injured area. An ultrasound gel might be administered during the ultrasound therapy session. The role of an ultrasound is to speed up your healing time and alleviate your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
