Role of physical therapy modalities in the treatment of myofascial pain
Most studies documenting the efficacy of physical therapy modalities are anecdotal and include relatively small subject numbers. They suggest the efficacy of transcutaneous electrical nerve stimulation (TENS), balneotherapy, ice, massage, ischemic compression (acupressure), and biofeedback in the treatment of myofascial pain. Low-power laser has been studied for its effect on myofascial pain associated with fibromyalgia. This modality seems to significantly reduce pain, muscle spasm, stiffness, and number of tender points.
