As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to reduce 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 improve the repairing process.
Ultrasound is administered 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 speed up your healing process and relieve your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
