As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue trauma to reduce swelling and pain, reduce muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that draws blood into the area in order to boost the mending process.
Ultrasound is applied gently 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 speed up your healing time and relieve 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)
