Effect of transcranial direct current stimulation in the initial weeks post-stroke: a pilot randomized study.

OBJECTIVE: This study aimed at assessing the alterations in upper limb motor impairment and connectivity between motor areas following the post-stroke delivery of cathodal transcranial direct current stimulation sessions. METHODS: Modifications in the Fugl-Meyer Assessment scores, connectivity between the primary motor cortex of the unaffected and affected hemispheres, and between the primary motor and premotor cortices of the unaffected hemisphere were compared prior to and following six sessions of cathodal transcranial direct current stimulation application in 13 patients (active = 6; sham = 7); this modality targets the primary motor cortex of the unaffected hemisphere early after a stroke. RESULTS: Clinically relevant distinctions in Fugl-Meyer Assessment scores (≥9 points) were observed more frequently in the Sham Group than in the Active Group. Between-group differences in the alterations in Fugl-Meyer Assessment scores were not statistically significant (Mann-Whitney test, p=0.133). ROI-to-ROI correlations between the primary motor cortices of the affected and unaffected hemispheres post-therapeutically increased in 5/6 and 2/7 participants in the Active and Sham Groups, respectively. Between-group differences in modifications in connectivity between the aforementioned areas were not statistically significant. Motor performance enhancements were more frequent in the Sham Group compared to the Active Group. CONCLUSION: The results of this hypothesis-generating investigation suggest that heightened connectivity may not translate into early clinical benefits following a stroke and will be crucial in designing larger cohort studies to explore mechanisms underlying the impacts of this intervention.

Success of promotion strategies for a stroke rehabilitation protocol.

OBJECTIVE: To prospectively evaluate the success of promotion strategies for a protocol of motor rehabilitation strategies for patients with stroke at Albert Einstein Hospital. METHODS: In a clinical trial of neuromodulation and rehabilitation for patients with stroke, conventional methods of dissemination and publications about the research protocol in social networks or on the hospital's website were performed. Frequencies of types of advertisements that reached potentially eligible subjects were calculated. RESULTS: Data from 80 potentially eligible patients were analyzed. The types of ads that motivated contacts more frequently were social media (38.8%) and information provided to physicians from other hospitals (23.8%) (p=0,288). The frequencies of contacts motivated by publications on the internet (53%) and conventional strategies (47%) were similar. Facebook was the digital strategy associated with the higher number of contacts, followed by the hospital's website. CONCLUSION: Social networks and websites can be as effective as traditional methods of advertisement, in order to reach patients for stroke rehabilitation protocols. These results may have an impact on the planning of clinical trials, including studies that evaluate effects of rehabilitation interventions in patients with stroke.

RESUMO OBJETIVO Avaliar prospectivamente o sucesso de estratégias de divulgação de um protocolo de reabilitação motora para indivíduos com doenças cerebrovasculares no Hospital Israelita Albert Einstein (HIAE). MÉTODOS Um ensaio clínico de neuromodulação e reabilitação para indivíduos com acidente vascular cerebral (AVC) e paresia do membro superior utilizou meios de divulgação digitais e meios tradicionais, não digitais. Foram calculadas frequências das modalidades de divulgação que alcançaram indivíduos potencialmente elegíveis para o protocolo. RESULTADOS Foram analisados dados de 80 indivíduos que manifestaram interesse em participar da pesquisa. As formas de divulgação mais frequentes que motivaram o contato foram redes sociais (38,8%) e informações fornecidas a médicos externos ao HIAE (23,8%). As frequências de contatos motivados por publicações na internet (53%) foram semelhantes às de contatos motivados por divulgações convencionais (47%) (p=0,288). Em relação às publicações sobre a pesquisa na internet, a divulgação pelo Facebook foi a mais eficiente, seguida pelo site do HIAE. CONCLUSÃO A divulgação de um protocolo de pesquisa em reabilitação por meio de publicações em redes sociais e sites pode ser tão eficaz quanto estratégias convencionais de comunicação. Estes resultados podem ter impacto no planejamento de ensaios clínicos, incluindo os que têm por objetivo avaliar efeitos de intervenções de reabilitação em indivíduos com AVC.
