As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue trauma to decrease swelling and pain, reduce muscle spasms, and increase the range of motion. Making 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 applied softly with a handheld soundhead, that uses strokes or circles over the pain stricken area. An ultrasound gel may be administered during the ultrasound therapy session. The role of an ultrasound is to expedite your healing time and alleviate your pain.
In one study, the adding of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
