ABSTRACT

RESUMO Objetivo Comparar os resultados nas tarefas de nomeação de pacientes afásicos após AVC dos grupos ativo e controle. Método Estudo duplo-cego, randomizado controlado com 14 pacientes. Os indivíduos foram submetidos a cinco sessões de 20 minutos de 2 mA em dias consecutivos. O catodo foi posicionado na área homóloga à Broca e o anodo sobre a região supraorbital do hemisfério esquerdo. Os testes de Boston e Snodgrass foram aplicados e os resultados comparados entre os grupos. Resultados Não houve resultados significativos para as sequências 1 e 2 no teste do Snodgrass. No teste de Boston, os dados indicaram uma diferença significativa para o tempo médio de acertos com estratégia. Conclusão Os resultados sugerem que a ETCC simultânea (anódica e catódica) é um método que pode auxiliar a reabilitação de pacientes com afasia do tipo anômica e de Broca, após AVC, e que as estratégias linguísticas deveriam ser consideradas nas análises das respostas dos testes de nomeação.


ABSTRACT Purpose Compare the results in naming tasks of after-stroke aphasic individuals divided into active and placebo groups pre- and post-transcranial direct current stimulation. Methods A double-blind, randomized, controlled study conducted with 14 individuals. Patients underwent five 20-min sessions with stimulation of 2mA's on consecutive days. The cathode was placed over the Broca's homologous area and the anode was placed over the supraorbital region of the left hemisphere. Boston and Snodgrass naming tasks were assessed before and after the stimulation sessions and the results were compared between the groups. Results No significant results were observed for sequences 1 and 2 in the Snodgrass test. The Boston test results indicated significant difference related to mean time for correct responses with strategy. Conclusion The results suggest that simultaneous transcranial direct current stimulation (anodic and cathodic) is a method that can improve the rehabilitation of patients with anomic and Broca's aphasia after stroke, and that language strategies should be considered in the analysis of naming task responses.
