As a therapeutic modality, ultrasound is a type of heat therapy for soft tissue damage to decrease swelling and pain, minimize muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that draws blood into the area in order to boost the repairing process.
Ultrasound is administered softly with a handheld soundhead, that uses strokes or circles over the injured area. An ultrasound gel may be administered during the ultrasound therapy session. The role of an ultrasound is to speed up your healing time and reduce your pain.
In one study, the addition of ultrasound to exercise treatment for lumbar spinal stenosis relief decreased the amount of analgesic consumption by the patients. (1)
