As a therapeutic modality, ultrasound is a type of heat treatment for soft tissue injuries to reduce swelling and pain, minimize 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 gently with a handheld soundhead, that uses strokes or circles over the affected area. An ultrasound gel might be applied during the ultrasound therapy session. The role of an ultrasound is to expedite your healing time and reduce your pain.
In one study, the addition of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
