As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue trauma to decrease swelling and pain, reduce muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound reaches deep into a damaged area, creating heat that pulls blood into the area in order to boost 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 relieve your pain.
In one study, the addition of ultrasound to exercise treatment for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
