[Arthromuscular interrelations in TMJ functional pathology]. / Interrelazioni artromuscolari nella patologia disfunzionale dell'ATM.

TMJ disorders includes: TMJ and masticatory muscles, pain, joint sounds, deviation and limitation of mandibular movements. A critical analysis of the literature dealing with the relationship between joint and muscle disorders in other joints (knee), leads to evaluate the reliability of the hypothesis of the existence of an arthro-myogenous relation in the aetiopathogenesis of craniomandibular disorders. As a preliminary conclusion we can say that the joint derangement seems the primary factor in the pathogenesis of TMJ disorders and cannot to differentiate muscle from joint involvement seems a difficult task.
