Resumo
A doença de Parkinson é caracterizada por sintomas motores como a bradicinesia, rigidez, tremor e instabilidade postural; e sintomas não motores como depressão, ansiedade e demência. Estes sintomas prejudicam a marcha, o equilíbrio, a cognição; acarretando prejuízos que afetam o funcionamento diário dos pacientes nas tarefas duplas, uma habilidade crucial para uma vida normal. O objetivo deste estudo foi realizar uma Revisão Sistemática sobre os efeitos das tarefas duplas sobre a marcha, o equilíbrio e a cognição destes pacientes. Os estudos foram selecionados das bases MEDLINE /PubMed e SciELO. Foi adotada a estratégia PICOS para determinar os critérios de elegibiliadade. A estratégia de busca foi realizada utilizando uma pesquisa avançada MEDLINE /PubMed e SciELO com os seguintes termos “Doença de Parkinson”, “Dupla Tarefa”, “Tarefas Concorrentes”, “Marcha”, “Caminhada”, “Equilíbrio”, “Treinamento”, “ Motor”, “ Intervenção”. Operadores boleanos AND e OR foram utilizados para a combinação dos termos. Foram identificados um total de 400 artigos: 377 artigos no PubMed/ MEDLINE, 21 artigos no SciELO e 2 artigos em buscas manuais. Após uma seleção inicial, 34 estudos foram analisados pelos critérios de elegibilidade e os critérios de exclusão, sendo que um total 11 estudos foram incluídos nesta revisão sistemática. De acordo com os estudos analisados nesta revisão, os diferentes tipos de intervenções incluídos permitem melhorias em vários indicadores da marcha, equilíbrio e cognição quando comparados a controles Parkinsonianos, porém como era esperado não surtiu efeito positivo quando comparados a controles sem a doença. Assim sendo, a utilização de estímulos externos parece desempenhar um papel positivo do treinamento em condições de dupla tarefa para estes pacientes.
Parkinson's disease is characterized by motor symptoms such as bradykinesia, rigidity, tremor and postural instability; and non-motor symptoms such as depression, anxiety and dementia. These symptoms impair gait, balance, cognition; causing losses that affect the daily functioning of patients in the dual tasks, a crucial skill for a normal life. The aim of this study was to perform a systematic review on the effects of dual tasks of the movement, balance and cognition in these patients. Studies were selected from MEDLINE / PubMed and SciELO. It was adopted PICOS strategy to determine the elegibility criteria. The search strategy was performed using an advanced search MEDLINE / PubMed and SciELO to the following terms "Parkinson's Disease", "Double Task", "Concurrent Tasks", "Gait", "Walk", "Balance", "Training" "Motor", "Intervention". Boolean operators AND and OR are used in the combination of terms. A total of 400 articles were identified: 377 articles in PubMed / MEDLINE, 21 articles in SciELO and 2 in manual searches. After an initial selection, 34 studies were analyzed by the eligibility criteria and exclusion criteria, and a total 11 studies were included in this systematic review. According to the studies analyzed in this review, the different types of interventions included allow improvements in several gait indicators, balance and cognition compared to Parkinsonian controls, but as expected not had a positive effect compared to controls without the disease. Thus, the use of external stimuli appear to play a positive role in the dual task of training conditions for these patients.
