As a therapeutic modality, ultrasound is a type of heat therapy for soft tissue damage to reduce swelling and pain, reduce muscle spasms, and expand the range of motion. Creating 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 administered gently with a handheld soundhead, using strokes or circles over the affected area. An ultrasound gel might be applied during the ultrasound therapy session. The role of an ultrasound is to speed up your healing time and reduce 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)
