RESUMO
Los puntos gatillo miofaciales (Pgs) son puntos hiperirritables en un músculo esquelético asociado a un nódulo palpable causado por una banda muscular tensa. Los Pgs miofaciales presentan dentro de sus signos y síntomas alteraciones motoras, sensoriales y autonómicas. En este artículo reportamos un caso en el que se presenta un fenómeno autónomo referido a partir de un punto gatillo miofacial y se plantean las vías neuroanatómicas involucradas en esta respuesta, analizando la hipótesis que las respuestas autónomas referidas asociadas al dolor pueden considerarse eventos neuropáticos del sistema nervioso autónomo.
Myofascial trigger points (MTP) are hyperirritable points in skeletal muscle associated with a palpable lump caused by a strained muscle band. MTP presented within signs and symptoms of motor, sensory and autonomic impairment. In this article we report a case in which an autonomous referred phenomena from a myofascial trigger point and raises the neuroanatomical pathways involved in this response, considering the hypothesis that self-related responses associated with neuropathic pain can be regarded as events of the autonomic nervous system. Clinical and experimental evidence discussed in this article indicates that myofascial trigger point pain is an autonomic phenomena associated, that can be systemic and localized, and must be considered in evaluating patients with these diagnosis.
