As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to minimize swelling and pain, reduce muscle spasms, and increase 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 enhance the repairing process.
Ultrasound is applied gently with a handheld soundhead, using strokes or circles over the pain stricken area. An ultrasound gel might be administered during the ultrasound therapy session. The role of an ultrasound is to speed up your healing process and relieve your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
