Course Description:

MPS is a regional pain disorder characterized by one or more myofascial trigger points in a taut band of muscle fibers and specific patterns of pain associated with each trigger point. Several mechanisms of injury have been proposed to cause MPS, but a common underlying pathology is a hyperirritable nociceptive neuron within the trigger point. Peripheral sensitization of nociceptors as well as central sensitization might explain the development of the persistent hyperalgesic state of trigger points. Fibromyalgia, a similar but more common and disabling muscle pain condition, should be ruled out. MPS is often chronic and refractory to conventional physical therapy. There is no consensus regarding best practice for treating trigger points. Methods often used to manage patients with MPS include various manual techniques, electrotherapeutic modalities, and acupuncture. Therapeutic exercise and functional training might be indicated to restore strength, flexibility, and normal posture in persons with MPS.
