As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to decrease swelling and pain, minimize muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that draws blood into the area in order to improve the healing process.
Ultrasound is administered gently 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 speed up your healing time and relieve your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
