As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue injuries to minimize swelling and pain, reduce 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 repairing process.
Ultrasound is applied gently with a handheld soundhead, using strokes or circles over the pain stricken 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 reduce your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
