The Xbox/Kinect use in poststroke rehabilitation settings: a systematic review.

BACKGROUND: Active games based on virtual reality have been widely used in the rehabilitation of many clinical conditions. However, studies on the use of Xbox/Kinect are rare, and technology application in stroke treatment is not clear yet. OBJECTIVE: To verify the outcomes (O) analyzed in randomized controlled trials (C; S) that investigated the use of Xbox/Kinect (I) in patients with stroke (P). METHODS: This is a systematic literature review that meets PRISMA standards and the eligibility criteria according to the PICOS strategy. The search procedure was performed by two researchers. The research strategy was repeated in case of divergence. Effect size was calculated by Cohen's formula and Hopkins rank. The risk of individual bias was assessed using PEDro Score and Higgins Classification. RESULTS: The main outcomes were postural balance and activities of daily living, with four studies addressing these variables. However, only one study showed the effect of Xbox/Kinect intervention on balance as large, as in two other studies evaluating manual dexterity and depression, respectively. CONCLUSION: The greater use of Xbox/Kinect in treating patients after stroke is in recovery of balance and motor function, and the evidence support its application. These findings enable the use of virtual reality technology through Xbox/Kinect in rehabilitation programs, focusing on postural balance and motor skills. However, conclusive results are still not possible. Therefore, caution in the use of this technology is required.

RESUMO Introdução: Jogos ativos baseados em realidade virtual têm sido amplamente utilizados na reabilitação de muitas condições clínicas. No entanto, estudos sobre a utilização do Xbox/Kinect são raros, e não está clara a aplicabilidade da tecnologia no tratamento de pacientes que tiveram acidente vascular cerebral. Objetivo: Verificar os desfechos (O) analisados em ensaios clínicos randomizados e controlados (C; S), que investigaram a utilização do Xbox/Kinect (I) em pacientes que tiveram acidente vascular cerebral (P). Métodos: Trata-se de uma revisão sistemática da literatura que atende aos padrões do PRISMA e aos critérios de elegibilidade, de acordo com a estratégia PICOS. O procedimento de busca foi realizado por dois pesquisadores e, em caso de divergência, a estratégia de busca foi repetida. O tamanho do efeito foi calculado por meio da fórmula de Cohen e da escala de Hopkins. O risco de viés individual foi analisado utilizando o escore PEDro e a classificação de Higgins. Resultados: Os principais desfechos foram o equilíbrio postural e as atividades de vida diária, com quatro estudos abordando essas variáveis. No entanto, apenas um estudo mostrou o efeito da intervenção com Xbox/Kinect sobre o equilíbrio como sendo grande, assim como em dois outros artigos que avaliaram destreza manual e depressão, respectivamente. Conclusão: A utilização mais comum do Xbox/Kinect no tratamento de pacientes que tiveram acidente vascular cerebral acontece na recuperação do equilíbrio e da função motora, e as evidências apoiam o seu uso. Esses achados permitem o uso da tecnologia de realidade virtual por meio do Xbox/Kinect em programas de reabilitação, com foco no equilíbrio postural e nas habilidades motoras. Porém, resultados conclusivos ainda não são possíveis, o que exige cautela no uso dessa tecnologia.
