As a therapeutic modality, ultrasound is a type of heat treatment for soft tissue trauma to minimize swelling and pain, minimize muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that pulls blood into the area in order to enhance the healing process.
Ultrasound is administered softly with a handheld soundhead, using 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 adding of ultrasound to exercise therapy for lumbar spinal stenosis relief decreased the amount of analgesic consumption by the patients. (1)
