As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue damage to decrease swelling and pain, reduce muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that draws blood into the area in order to boost the healing process.
Ultrasound is applied gently with a handheld soundhead, that uses strokes or circles over the injured 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 relieve your pain.
In one study, the adding of ultrasound to exercise therapy for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
