O acidente vascular encefálico (AVE) causa alta taxa de morte e incapacidade funcional, afetando a autonomia dos pacientes. A estimulação do nervo vago (VNS) é promissora na recuperação, mas exige cirurgia invasiva com possíveis efeitos adversos. Como alternativa, explora-se a estimulação transcutânea do nervo vago (taVNS), uma opção menos invasiva para a reabilitação pós-AVE. Este estudo, seguindo o protocolo PRISMA, identificou 350 artigos, dos quais 3 artigos foram selecionados para a revisão por se alinharem à temática e aos objetivos do trabalho. Os efeitos dos protocolos de VNS são avaliados com base em desfechos clínicos, como a pontuação na avaliação Fugl-Meyer do membro superior, o teste de função motora de Wolf, a Medida de Independência Funcional e a avaliação de Brunnstrom. Embora a taVNS tenha mostrado resultados positivos, são necessários mais estudos para determinar o protocolo ideal devido a limitações como amostras pequenas e falta de acompanhamento a longo prazo. A estimulação do nervo vago auricular ativada por motor também se mostrou eficaz na reabilitação motora pós-AVE, com menos custos e riscos que o VNS implantado. Além disso, mais pesquisas são necessárias para otimizar os tratamentos e avaliar a taVNS em diferentes fases do AVE.
