Efeitos da Estimulação Transcraniana por Corrente Contínua nas alterações de Fala e Voz para a Doença de Parkinson: uma Revisão Sistemática com Metanálise

RESUMO Objetivo Esta metanálise tem o objetivo de avaliar a evidência existente dos efeitos da tDCS nas alterações de fala e de voz de pacientes com DP. Estratégias de Pesquisa PubMed, LILACS, EMBASE, Cochrane Central Register of Controlled Trials, Science Direct, Web of Science, Scopus e de literatura cinzenta Google Scholar e Open Grey. A busca incluiu os descritores: “Parkinson Disease, Transcranial Direct Current Stimulation, Voice, Speech” combinados com AND e OR. Critérios de Seleção Pacientes com a Doença de Parkinson, ambos os sexos. Uso da Estimulação Transcraniana por Corrente Contínua (tDCS) para tratar os parâmetros de voz e fala nos pacientes acometidos pela Doença de Parkinson. Análise de dados Um total de 1.345 artigos, 14 artigos incluídos na revisão sistemática e 6 artigos na metanálise. O risco de viés e o nível de evidência foram avaliados pelo software REVIEW MANAGER 5.4.1. e GRADE. Resultados Os resultados mostraram um tamanho de efeito geral da tDCS de Z= 0.89 (P=0.37). Estudos com área alvo no córtex pré-frontal (PFC) apresentaram maior tamanho de efeito 1.38(P=0.17), portanto com maior impacto para desfecho de fala e voz com uso de tDCS para DP. Três estudos apresentaram baixo risco de viés e três estudos apresentaram risco pouco claro. Conclusão Apesar do baixo número de estudos, os achados desta metanálise sugerem a potencial aplicabilidade da tDCS como ferramenta adjuvante no tratamento das alterações de voz e fala em pacientes com DP.
