Resumo
Objetivo: investigar os efeitos da estimulação transcraniana por corrente contínua (tDCS) anódica sobre o córtex pré-frontal dorsolateral esquerdo, combinada a intervenções fonoaudiológicas com Comunicação Aumentativa e Alternativa (CAA), no nível de comunicação de crianças com paralisia cerebral (PC) classificadas entre os níveis III e V do Sistema de Classificação da Função de Comunicação (CFCS).
Métodos: seis crianças (6-12 anos) realizaram dez sessões de tDCS (1 mA; 20 min) associadas ao treino de vocabulário essencial via TD Snap®. O nível de comunicação foi avaliado antes e após a intervenção pela Matriz de Comunicação. A segurança foi monitorada por relatos de eventos adversos.
Resultados: todos os participantes concluíram o protocolo, com boa tolerabilidade e ausência de eventos adversos graves. Observou-se tendência de melhora no nível de comunicação, com progressão de pelo menos um nível na Matriz de Comunicação em todos os casos. Sensação de formigamento foi tolerável e a vermelhidão local apresentou-se transitória.
Conclusão: a combinação tDCS + CAA mostrou-se viável, segura e potencialmente eficaz para aprimorar a comunicação em crianças com PC moderada à grave. São necessários estudos controlados, com amostras maiores e seguimento prolongado, para confirmar a efetividade e otimizar os parâmetros de intervenção.
