About
Temporomandibular disorders (TMD) are a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints, the masticatory muscles, and all associated tissues. These disorders are characterized by regional pain and limitation of mandibular range of motion. Pain-related TMD affects approximately 5% to 12% of the population and can affect individual's quality of life. The incidence is about 4 percent. Therapeutic ultrasound is a type of physical therapy that delivers energy via propagation of ultrasonic waves. One gap in knowledge is whether 1 megahertz (MHz) treating frequency has the same efficacy as treating with 3 MHz. This research proposes to test that.
