As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue damage 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 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 administered during the ultrasound therapy session. The role of an ultrasound is to speed up your healing time 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)
