Chronic pain syndromes and their treatment II. trigger points

  • Gordon M. Wyant


Trigger points are distinct areas of focal hyperirritability which give rise to areas of referred pain in well-defined areas of the musculoskeletal system, sometimes remote from the point itself and not related to it by anatomically definable pathways. While the vast majority of pain manifestations from trigger points are related to the musculo-skeletal system, this need not be invariably so, as has been demonstrated in two of the cases cited, where injection of trigger points in the neck relieved chronic tinnitus. In all manifestations of chronic pain it is recommended that a diligent search be made for such trigger points.


Les zones gachettes sont dans le muscle des points ďhyperirritabilitRé focale qui donnent lieu Rà des projections douloureuses dans des rRégions bien dRéfinies du systRème musculo-squelettique souvent RéloignRées de la zone gachette elle-mRême et sans relation anatomique dRémontrable. Bien que la plupart du temps, Rľirradiation douloureuse Rà partir des zones gachettes intRéresse le systRème musculo-squelettique, il nR’en est pas toujours ainsi comme le dRémontrent deux observations au cours desquelles Rľinfiltration de zones gachettes dans le cou a fait disparaRître un bourdonnement ďoreille chronique. Dans toutes les manifestations de douleurs chroniques, Rľauteur recommande de rechercher avec application les zones gachettes.
