Introdução: A síndrome dolorosa miofascial designa a dor muscular regional causada por trigger points. Esses são caracterizados como pontos de hiperirritabilidade presentes na musculatura, cuja palpação induz í reprodução de sintomas. Os dispositivos luminosos (LASER"™s e LED"™s) são citados na literatura como uma nova modalidade para o tratamento dessa síndrome. Objetivo: Avaliar os efeitos do laser de baixa intensidade na modulação da dor de indivíduos portadores de síndrome dolorosa miofascial. Métodos: Dois indivíduos foram aleatoriamente alocados em dois grupos – laser de baixa intensidade (LBI) e compressão isquêmica (CI). O sinal eletromiográfico dos músculos trapézio superior e médio e a intensidade da dor foram coletados diariamente antes e após as intervenções. Resultados: A intensidade da dor pré e pós-intervenção apresentaram diferenças significativas, em repouso e em movimento, apenas para o grupo LBI. Diferenças significativas não foram observadas na intensidade da dor ao longo das 8 sessões nos grupos avaliados. Não foram encontradas diferenças entre a atividade muscular de nenhum dos músculos em ambos os grupos, a curto e a longo prazo. Conclusão: Ambas as intervenções acarretaram efeitos benéficos distintos sob a síndrome dolorosa miofascial. A combinação das duas técnicas pode ser uma alternativa interessante para o tratamento desta síndrome.
Palavras-chave: síndrome dor miofascial, terapia a laser de baixa intensidade, eletromiografia.
