Summary: | Introduction: Virtual reality (VR) is used nowadays as an assessment and intervention tool in rehabilitation. One of the capabilities that can be assessed through VR is coincident timing, a perceptual-motor ability to execute a motor response in synchrony with an external stimulus. Visually impaired (VI) people need this synchronization of movements with external objects in their daily and leisure activities. Objective: To investigate the performance of VI individuals in a VR coincident timing task. Methods: Quantitative cross-sectional study with an interventional, quasi-experimental, descriptive, and explanatory nature. Sixty individuals participated in this study: 20 VI, 20 blindfolded and 20 non-VI, over 18 years of age. A semi-structured interview and a virtual coincident timing task were used. Results: VI individuals started the task with the worst performance (Absolute error = group VI 945ms x blindfolded group 591ms x control group 557ms), but they improved throughout the task, as well as all groups, reducing the number of errors (mean absolute error= 698ms to 408ms). Furthermore, all groups increased task speed (mean variable error= last acquisition block 408ms x immediate transfer 227ms x late transfer 247ms). Conclusion: It is concluded that VI individuals can develop motor learning from tasks in VR, showing the importance of taking advantage of these technological advances in this area, not only as a facilitator of task execution, but also as an instrument that enable rehabilitation programs to ensure functional improvements for real everyday tasks.
Introdução: A realidade virtual (RV) é usada atualmente como ferramenta de avaliação e intervenção na reabilitação. Uma das capacidades possivelmente verificadas por meio da RV é o tempo coincidente: habilidade perceptivo-motora de executar uma resposta motora em sincronia com um estímulo externo. Essa sincronização de movimentos com estímulos externos é importante para pessoas com deficiência visual (DV) nas tarefas diárias e de lazer. Objetivo: Investigar o desempenho de indivíduos com DV em uma tarefa de tempo coincidente de RV. Método: Estudo transversal quantitativo e intervencionista, quase experimental, descritivo e explicativo. Participaram 60 indivíduos: 20 DV, 20 vendados e 20 não-DV, maiores de 18 anos. Foi utilizada entrevista semiestruturada e uma tarefa de tempo coincidente. Resultados: O grupo DV iniciou a tarefa com o pior desempenho (erro absoluto = grupo DV 945ms x grupo vendado 59 |
