title: Identification of myofascial trigger point syndromes: a case of atypical facial neuralgia.
abstract: Myofascial trigger points (TPs) in a muscle are usually activated by acute or chronic overload of the muscle. They are identified by objective and subjective findings. Objective signs include a palpably firm, tense band in the muscle, production of a local twitch response, restricted stretch range-of-motion, weakness without atrophy, and no neurologic deficit. Subjectively, the patient reports stiffness and easy fatigability, spontaneous pain in a distribution predictable for that TP, an exquisite deep tenderness specifically at the TP. Sustained pressure on the TP induces referred pain in the predicted pattern. Some muscles are likely to produce additional objective and subjective autonomic concomitants. Laboratory and radiographic findings are negative. The affected muscle is treated by passive stretch while a jet stream of vapocoolant spray is applied over it, or by injection of the TP with a local anesthetic. A case report describes in detail the treatment of a patient who, for 13 years, had suffered from a medically enigmatic, intense right facial pain with severe dysfunction and who is now pain-free, with a full schedule of unrestricted activities 23 years later.
