Physical therapy treatments are geared toward reducing inflammation and discomfort; this can be done with electric muscle stimulation, therapeutic ultrasound and manual treatments such as deep tissue massage and passive joint immobilization. Thermal modalities like ice and heat are also utilized depending on the severity and acuteness of the injury. Once pain has been reduced and inflammation has subsided the in treatment focus shifts to restoring function. This induces strength and flexibility training, gait training, appropriate balance training and other specialized therapies. Education in ergonomics, injury prevention and home exercises are a crucial component to a thorough care plan.
