As a therapeutic modality, ultrasound is a type of heat treatment for soft tissue trauma to minimize swelling and pain, reduce muscle spasms, and expand 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 applied softly with a handheld soundhead, that uses strokes or circles over the injured area. An ultrasound gel might be applied during the ultrasound therapy session. The role of an ultrasound is to expedite your healing time and reduce your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
