As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue damage to minimize swelling and pain, minimize muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound reaches deep into a damaged area, creating heat that draws blood into the area in order to improve the mending process.
Ultrasound is applied softly with a handheld soundhead, using strokes or circles over the injured area. An ultrasound gel may 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 therapy for lumbar spinal stenosis relief decreased the amount of analgesic consumption by the patients. (1)
