As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to reduce swelling and pain, minimize muscle spasms, and increase the range of motion. Creating high frequency sound waves, ultrasound reaches deep into a damaged area, creating heat that draws blood into the area in order to boost the mending process.
Ultrasound is administered softly with a handheld soundhead, using strokes or circles over the injured area. An ultrasound gel may 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 treatment for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
