As a therapeutic modality, ultrasound is a type of heat therapy for soft tissue trauma to minimize swelling and pain, minimize muscle spasms, and increase the range of motion. Making high frequency sound waves, ultrasound reaches deep into an injured area, creating heat that draws blood into the area in order to enhance the healing 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.
