As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue injuries to decrease swelling and pain, minimize muscle spasms, and increase 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 enhance the healing process.
Ultrasound is applied softly with a handheld soundhead, that uses strokes or circles over the pain stricken area. An ultrasound gel might be applied during the ultrasound therapy session. The role of an ultrasound is to expedite your healing process and reduce your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
