Effect of the dry needling vs manual myofascial therapy at the trigger points in temporomandibular dysfunction

摘要

Introduction: The etiology of Temporomandibular Dysfunction (TMD) is multidimensional, considering biomechanical, neuromuscular and biopsychosocial [1]. TMDs are defined in subgroups as problems involving temporomandibular joint (TMJ), masticatory system muscles, and musculoskeletal structures associated with the head and neck [2]. The most relevant signs of TMD are the presence of joint sounds (clicking and crepitation), reduced mouth opening, and disrupted jaw movements. However, pain is the primary problem of this pathology, and it is typically the reason these patients request medical care [3]. The muscular etiology TMD includes the myofascial pain syndrome, which is characterized by the presence of trigger points (TP). The intervention of physical therapy in TP involves myofascial manual therapy and dry needling [4]. The purpose of this study was to investigate the effect of physiotherapy technique for the treatment of muscular TMD by applying manual myofascial therapy and dry needling.
