Te use of dry needling in the treatment of cervical and masticatory myofascial pain

ABSTRACT BACKGROUND AND OBJECTIVES: Dry needling is an interventionist, minimally invasive technique, used in the treatment of myofascial pain. The objective of this study was to describe the use of dry needling and to perform a critical literature analysis about the technical aspects of its use by qualified health care professionals. CONTENTS: A search in the literature was carried out for books in English, review articles, randomized controlled or quasi-randomized clinical trials, blind or double-blind and published case studies series in Portuguese or in English. The following databases were used: Cochrane, LILACS, and Pubmed. Articles published from September 1996 to January 2017 were selected according to the following keywords: dry needling versus myofascial pain syndrome versus temporomandibular joint dysfunction syndrome) versus trigger points versus musculoskeletal manipulations versus trapezius muscle, superficial back muscles versus masseter muscle versus secular muscle versus pterygoid muscles versus digastric muscle, neck muscles. Reports of clinical cases, “open-label” studies, studies with animal models and articles not related to DN were excluded. After the matching descriptors and the implementation of inclusion and exclusion criteria, we selected six articles. CONCLUSION: The diagnosis of myofascial pain can be a difficult task since it can simulate different masticatory system pain, from a toothache to a trigeminal neuropathic pain. This can be minimized with proper history taking, clinical examination involving muscle palpation, as well as the own experience and professional training. The deactivation of myofascial trigger points should be a priority in myofascial pain therapy since there is a significant improvement of local and referred pain when we use this approach. Despite the favorable results of studies about the use of dry needling in myofascial pain treatment related to temporomandibular joint dysfunction and the cervical region, the literature still lacks studies with a high level of evidence proving the effectiveness and efficacy of this technique. This is a minimally invasive, low cost, and safe therapy that provides local, segmental, extra segmental and placebo effects. Therefore, its use should be recommended by different health professionals in cases of myofascial pain.
