As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue injuries to decrease swelling and pain, reduce 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 enhance the repairing process.
Ultrasound is administered softly with a handheld soundhead, using strokes or circles over the affected area. An ultrasound gel may be administered during the ultrasound therapy session. The role of an ultrasound is to expedite your healing process and alleviate your pain.
In one study, the adding of ultrasound to exercise therapy for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
