As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue injuries to decrease 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 draws blood into the area in order to improve the repairing process.
Ultrasound is administered gently 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 process and reduce your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
