As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to decrease swelling and pain, minimize muscle spasms, and expand the range of motion. Making high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that pulls blood into the area in order to enhance the repairing 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 expedite your healing process and reduce your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
