As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue trauma to reduce swelling and pain, reduce muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that pulls blood into the area in order to enhance the repairing process.
Ultrasound is administered softly with a handheld soundhead, that uses strokes or circles over the affected area. An ultrasound gel might be administered during the ultrasound therapy session. The role of an ultrasound is to expedite your healing process and reduce your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief decreased the amount of analgesic consumption by the patients. (1)
