Objetivos: O presente estudo tem como objetivo comparar o efeito da estimulação transcraniana de corrente contínua aplicada no córtex dorsolateral esquerdo e no córtex motor bilateral no tempo de reação, mobilidade funcional e equilíbrio em tarefa simples e dual-task de indivíduos com doença de Parkinson.
Métodos: Este estudo segue um desenho longitudinal quantitativo experimental crossover, tratando-se de um ensaio clínico randomizado duplo-cego. A amostra foi composta por 7 participantes com doença de Parkinson com idade média de 62 anos. Foi realizada uma avaliação inicial, na qual foi aplicado o questionário sociodemográfico, MoCA, Escala de Hoehn & Yahr e domínios II e III da UPDRS. Pré e pós intervenção foi feita uma avaliação da velocidade de reação, da mobilidade funcional, do sentar-levantar e do equilíbrio em tarefa simples e dupla. Todos os participantes foram sujeitos a três intervenções, uma sessão na qual a estimulação foi aplicada no córtex motor bilateral (CMB), uma com aplicação no córtex dorsolateral esquerdo (CDE) e uma Sham, seguindo uma ordem aleatória.
Resultados: Os resultados estatísticos obtidos não permitiram concluir qual o tipo de estimulação que apresenta melhores resultados nas variáveis em estudo. No entanto, na comparação das médias dos resultados obtidos nas avaliações pré e pós intervenção verificou-se uma melhoria nos resultados da mobilidade funcional, do sentar-levantar e no equilíbrio de olhos abertos e fechados na estimulação do CMB. Na intervenção no CDE observaram-se melhorias na mobilidade funcional em tarefa simples e dupla, e no equilíbrio de olhos abertos na direção ântero-posterior e com os olhos fechados.
Conclusão: Na estimulação do CMB foram observadas melhorias na velocidade de reação, mobilidade funcional não associada ao desempenho de tarefas cognitivas em simultâneo, e no equilíbrio, principalmente de olhos fechados, onde estão ausentes mecanismos de biofeedback. Por sua vez, a estimulação do CDE apresentou melhorias na mobilidade funcional quando associada ao desempenho simultâneo de uma tarefa cognitiva (dual-task), e no equilíbrio quer nas recolhas realizadas de olhos abertos, como nas recolhas executadas de olhos fechados.
Objective: The aim of the present study was to compare the effect of Transcranial Direct Current Stimulation on the left dorsolateral cortex and the bilateral motor cortex on the reaction time, functional mobility, and single task and dual-task balance of individuals with Parkinson's disease. Methods: This study follows a longitudinal quantitative experimental cross-over design, in a randomized double-blind clinical trial. The sample consisted of 7 participants with Parkinson's disease, with mean age of 62 years. An initial evaluation was carried out, in which the sociodemographic questionnaire, MoCA, Hoehn & Yahr Scale and UPDRS domains II and III were applied. The pre and post-intervention evaluation consisted in an evaluation of reaction speed, functional mobility, sit-up and balance was performed in a single and dual task. All participants were submmited to three interventions, one session in which stimulation was applied in the bilateral motor cortex (CMB), one in the left dorsolateral cortex (CDE) and one Sham stimulation, following a random order. Results: The statistical results obtained did not allow to conclude the type of stimulation that presents better results in the variables under study. However, in the comparison of the means of the results obtained in the pre and post-intervention evaluations, was observed an improvement in the results of functional mobility, sit-up evaluation and balance with the eyes open and closed in the stimulation of CMB. In the CDE intervention, improvements were observed in functional mobility in single and dual task, and in the balance with the eyes open and closed. Conclusion: In the stimulation of CMB, there were improvements in the reaction speed; functional mobility not associated to the performance of cognitive tasks simultaneously; and in balance, especially with closed eyes, where biofeedback mechanisms are absent. CDE stimulation, on the other hand, presented improvements in functional mobility when associated with dual-task, and in the balance between open-eye collections and closed-eye collections.
