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 penetrates deep into a damaged area, creating heat that pulls blood into the area in order to boost 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 speed up 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)
