As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue damage to decrease 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 pulls blood into the area in order to enhance the repairing process.
Ultrasound is applied gently with a handheld soundhead, that uses strokes or circles over the pain stricken area. An ultrasound gel might be applied 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 therapy for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
