Resumo
Introdução: Eletroestimulação é um recurso utilizado em diversos tipos de tratamento dentro da fisioterapia, sendo a dor, o sintoma mais comum a ser tratado; incluindo a dor cervical, um problema de saúde pública de alta incidência na sociedade. Correntes de baixa frequência, como a estimulação elétrica transcutânea (TENS), são as mais utilizadas clinicamente; entretanto, quando comparadas às de média frequência, possuem maior desconforto durante a aplicação; além de menor impedância à passagem pela pele, atingindo assim, camadas mais profundas. Objetivo: Analisar o efeito das correntes de baixa e média frequência sobre a dor cervical e a atividade eletromiográfica dos músculos trapézio e esternocleidomastóideo. Métodos: Projeto aprovado pelo Comitê de Ética em Pesquisa em Seres Humanos FFC-UNESP pelo parecer n° 2.670.186 e realizada de acordo com a Resolução 466/12 do Conselho Nacional de Saúde. A 30 mulheres participaram deste estudo. Foi realizada uma avaliação inicial composta por Escala Visual Analógica de dor, Algometria e Eletromiografia em trapézio e esternocleidomastóideo. Em seguida, foi realizada aleatorização das voluntárias em três grupos: grupos Controle, Tens e Aussie. Após a aplicação da corrente, foi realizada uma reavaliação. Resultado: Não foi observada significância estatística para o fator grupo, avaliações (pré e pós) e nem para interação grupo x avaliações. Conclusão: Conclui-se que não foi observada diferença ao analisar o efeito das correntes de baixa e média frequência sobre a dor cervical e a atividade eletromiográfica dos músculos trapézio e esternocleidomastóideo.
Introduction: Electrostimulation is a resource used in different types of treatment within physiotherapy, with pain being the most common symptom to be treated; including cervical pain, a public health problem with high incidence in society. Low frequency currents, such as transcutaneous electrical stimulation (TENS), are the most used clinically; however, when compared to those of medium frequency, they have greater discomfort during application; in addition to lower impedance passing through the skin, thus reaching deeper layers. Objective: Analyze the effect of low and medium frequency currents on neck pain and the electromyographic activity of the trapezius and sternocleidomastoid muscles. Methods: Project approved by the Ethics Committee for Research in Human Beings FFC-UNESP under Opinion No. 2,670.186 and carried out in accordance with Resolution 466/12 of the National Health Council. 30 women participated in this study. An initial assessment was performed, consisting of a Visual Pain Scale, Algometry and Electromyography of trapezius and sternocleidomastoid. Then, the volunteers were randomized into three groups: Control group, TENS and Aussie group. After the treatment (one session), a reassessment was performed. Results: There was no statistical significance between the group factor, assessments (pre and post) neither to the group x assessments interaction. Conclusion: It is concluded that was no difference between low and medium frequency currents on neck pain and the electromyographic activity of the trapezius and sternocleidomastoid muscles.
