As a therapeutic modality, ultrasound is a form of heat therapy for soft tissue trauma to minimize swelling and pain, minimize muscle spasms, and expand the range of motion. Making high frequency sound waves, ultrasound penetrates deep into an injured area, creating heat that draws blood into the area in order to boost the mending process.
Ultrasound is applied softly with a handheld soundhead, that uses 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 expedite your healing time and relieve your pain.
In one study, the adding of ultrasound to exercise treatment for lumbar spinal stenosis relief reduced the amount of analgesic usage by the patients. (1)
