As a therapeutic modality, ultrasound is a type of heat therapy for soft tissue trauma to minimize swelling and pain, minimize muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that draws blood into the area in order to improve the healing process.
Ultrasound is applied gently with a handheld soundhead, using strokes or circles over the pain stricken area. An ultrasound gel may 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 decreased the amount of analgesic consumption by the patients. (1)
