As a therapeutic modality, ultrasound is a type of heat therapy for soft tissue damage to minimize swelling and pain, minimize muscle spasms, and expand the range of motion. Creating high frequency sound waves, ultrasound penetrates deep into a damaged area, creating heat that draws blood into the area in order to improve the healing process.
Ultrasound is applied gently with a handheld soundhead, using strokes or circles over the affected 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 alleviate your pain.
In one study, the addition of ultrasound to exercise therapy for lumbar spinal stenosis relief reduced the amount of analgesic consumption by the patients. (1)
