Enigma of myofascial pain-dysfunction syndrome - A revisit of review of literature
Keywords:Myalgia, myofascial pain-dysfunction syndrome, referred pain, trigger points
Myofascial pain-dysfunction syndrome (MPDS) is a form of myalgia that is characterized by local regions of muscle hardness
that are tender and cause pain to be felt at a distance, i.e., referred pain. The central component of the syndrome is the trigger
point (TrP) that is composed of a tender, taut band. Stimulation of the band, either mechanically or with activity, can produce
pain. Masticatory muscle fatigue and spasm are responsible for the cardinal symptoms of pain, tenderness, clicking, and limited
function that characterize the MPDS. Since MPDS covers a wide range of symptoms, it might be difficult to diagnose and provide
definitive treatment. A better understanding and working knowledge of TrPs and MPDS offers an effective approach to relieve
pain, restore function, and contribute significantly to patient’s quality of life.
