Os pontos-gatilho musculares hipersensíveis da dor miofascial no Distúrbio Temporomandibular (DTM) afetam a qualidade de vida. O objetivo deste estudo foi avaliar a eficácia da acupuntura e da terapia com laser de baixa intensidade no alívio da dor relacionada à DTM. Foi realizado um ensaio clínico randomizado com 14 participantes (10 mulheres, 4 homens; média de 29,5 anos) divididos em dois grupos (n=7). O Grupo 1 recebeu dez sessões de acupuntura de 20 minutos a cada 48 horas, enquanto o Grupo 2 foi submetido à terapia com laser infravermelho de baixa potência (790 nm, 120 mW) na mesma frequência. A dor foi avaliada por meio da Escala Visual Analógica (EVA) de 0 a 10, e a atividade neuromuscular por eletromiografia (EMG) bilateral dos músculos temporal e masseter. A análise estatística foi realizada com o software SPSS 22.0, utilizando os testes de Wilcoxon e t pareado (p<0,05). Ambos os tratamentos reduziram significativamente a percepção subjetiva da dor (EVA: Acupuntura de 6,57 para 0,14; Laser de 6,00 para 1,20), sem diferença significativa entre os grupos. No entanto, nenhuma das terapias reduziu significativamente a atividade neuromuscular dos músculos temporal e masseter, embora a acupuntura tenha mostrado uma tendência à redução da atividade do músculo temporal durante o apertamento. A acupuntura e a terapia com laser de baixa intensidade foram eficazes na redução da dor em pacientes com DTM. Apesar das diferenças nos padrões neuromusculares, nenhum dos tratamentos alterou significativamente a atividade muscular, indicando a necessidade de mais pesquisas para explorar seus mecanismos subjacentes.
