RESUMO

INTRODUCTION: Non-fluent aphasia is a frequent complication in post-ischemic stroke patients, with repetitive transcranial magnetic stimulation (rTMS) being one of the possible treatment alternatives. AIM: To assess the efficacy and safety of rTMS in patients with non-fluent after-ischemic stroke aphasia. PATIENTS AND METHODS: Double blind, randomized controlled clinical trial in post-stroke patients who were assigned to receive 10 sessions (one daily) of active treatment or placebo of rTMS, without the addition of language therapy. The baseline characteristics were compared initially and the efficacy between the active group versus the placebo group at day 30 was evaluated through a Mann-Whitney U test. RESULTS: 82 patients were included: active group (n = 41) and placebo group (n = 41). At baseline, statistically significant differences were found between the groups in favor of the placebo in the domains of the Boston test of auditory compression (p = 0.024), denomination (p = 0.014) and praxis (p = 0.026), and also occurred on the 30th day in the naming domains (p = 0.037) and reading (p = 0.001). There were 39 adverse reactions: 23 (26.83%) in the active group vs 16 (21.96%) in the placebo group (p = 0.290); the majority corresponded to episodes of mild headache. CONCLUSION: rTMS is a safe therapy, however, given the conditions of this study, we could not demonstrate the efficacy of rTMS versus placebo in patients with non-fluent aphasia with involvement of Broca's area after an ischemic stroke.


TITLE: Eficacia y seguridad de la estimulacion magnetica transcraneal en pacientes con afasia no fluente, posterior a ictus isquemico. Ensayo clinico controlado, aleatorizado y doble ciego.Introduccion. La afasia no fluente es una complicacion frecuente en pacientes postictus isquemico y la estimulacion magnetica transcraneal repetitiva (EMTr) representa una de las posibles alternativas de tratamiento. Objetivo. Evaluar la eficacia y la seguridad de la EMTr en pacientes con afasia no fluente postictus isquemico. Pacientes y metodos. Ensayo clinico controlado doble ciego, aleatorizado, en pacientes postictus isquemico que fueron asignados a recibir 10 sesiones (una diaria) de tratamiento activo o placebo de EMTr, sin adicion de terapia del lenguaje. Las caracteristicas basales fueron comparadas inicialmente, y la eficacia entre el grupo activo frente al grupo placebo el dia 30 se evaluo a traves de una prueba U de Mann-Whitney. Resultados. Se incluyo a 82 pacientes: grupo activo (n = 41) y grupo placebo (n = 41). Se encontraron diferencias basales estadisticamente significativas entre los grupos a favor del placebo en los dominios del test de Boston de compresion auditiva (p = 0,024), denominacion (p = 0,014) y praxis (p = 0,026), e igualmente ocurrio el dia 30 en los dominios de denominacion (p = 0,037) y lectura (p = 0,001). Se presentaron 39 reacciones adversas, 23 en el grupo activo (26,83%) frente a 16 (21,96%) en el grupo placebo (p = 0,290), y la mayoria correspondia a episodios de cefalea leve. Conclusion. La EMTr es una terapia segura, pero dadas las condiciones de este estudio, no pudo demostrarse la eficacia de la EMTr frente al placebo en pacientes con afasia no fluente con afectacion del area de Broca posterior a un ictus isquemico.
