Introdução: Os trigger points miofasciais são caracterizados como pontos locais hipersensíveis que normalmente formam uma banda tensa palpável dentro das fibras musculares esqueléticas, podendo ser de 2 tipos: ativos ou latentes. Uma das formas descritas de tratamento é a técnica de dry needling. Objetivo: Analisar os efeitos de duas técnicas de dry needling (com e sem manipulação) no padrão de ativação eletromiográfico e na dor do trigger point latente do músculo trapézio superior, comparativamente a uma técnica de impostura ou placebo. Metodologia: Participaram no estudo 26 indivíduos, tendo sido distribuídos de forma aleatória em 3 grupos de tratamento: placebo, puntura simples e técnica de dry needling com manipulação. Todos os grupos foram submetidos a avaliação da dor e do padrão de activação electromiográfico antes e após a técnica de puntura, assim como 24 horas após dor. Resultados: Não se obteve diferenças significativas em termos de dor e padrão eletromiográfico (sEMG) antes e após cada uma das técnicas de dry needling e 24h após. Conclusão: A aplicação da técnica de dry needling, com manipulação ou sem manipulação, em trigger points latentes não induziu alterações no limiar de dor e no padrão electromiográfico da amostra em estudo.
Introduction: The myofascial trigger points are characterized as hypersensitive local spots that are usually formed within a palpable taut band of skeletal muscle fibers, and they may be described as active or latent. One of the described forms of treatment is the dry needling technique. Objective: To analyze the effect of two dry needling techniques (with and without manipulation) on upper trapezius muscle latent trigger points with comparison to a sham technique. Methods: 26 subjects took part in the study, who was randomly assigned to 3 different groups: sham or placebo, dry needling technique with and without manipulation. All the groups have been assessed for pain and electromyographic pattern before and after treatment and 24 hours later. Results: The present study did not find statistical differences in terms of pain and electromyographic pattern (sEMG) before and after each technique of dry needling and 24h later (pain). Conclusion: The dry needling application, with and without manipulation, did not induce changes on electromyographic pattern and pain threshold, on latent trigger points, in the sample under study.
