As a therapeutic modality, ultrasound is a type of heat treatment for soft tissue trauma to minimize swelling and pain, reduce muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound penetrates deep into an injured area, creating heat that draws blood into the area in order to boost the healing process.
Ultrasound is applied softly with a handheld soundhead, using 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 time and reduce your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
