As a therapeutic modality, ultrasound is a type of heat treatment for soft tissue injuries to minimize swelling and pain, minimize muscle spasms, and increase the range of motion. Creating high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that draws blood into the area in order to boost the repairing process.
Ultrasound is administered softly with a handheld soundhead, using strokes or circles over the pain stricken area. An ultrasound gel may be administered 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 adding of ultrasound to exercise therapy for lumbar spinal stenosis relief decreased the amount of analgesic usage by the patients. (1)
