Ultrasound therapy is one of the best forms of heat treatment for soft tissue injuries such as muscle sprains, bursitis, and tendonitis. It increases blood supply in order to promote healing. It reduces pain by decreasing muscle spasms and encouraging normal function. And it softens fibrous tissues and scar tissue.

Ultrasound is a high-frequency wave that cannot be heard by the human ear. It is applied to the body with an ultrasound machine. A gel is used to help the waves travel into the body rather than reflect off the skin. The waves are transferred in either a “pulse” mode, which prevents tissues from heating, or a “continuous” mode, which transfers the heat to the body tissues.
