To determine the clinical feasibility of a system based on augmented reality for upper-limb (UL) motor rehabilitation of stroke participants.
A physiotherapist instructed the participants to accomplish tasks in augmented reality environment, where they could see themselves and their surroundings, as in a mirror. Two case studies were conducted. Participants were evaluated pre- and post-intervention. The first study evaluated the UL motor function using Fugl-Meyer scale. Data were compared using non-parametric sign tests and effect size. The second study used the gain of motion range of shoulder flexion and abduction assessed by computerized biophotogrammetry.
At a significance level of 5%, Fugl-Meyer scores suggested a trend for greater UL motor improvement in the augmented reality group than in the other. Moreover, effect size value 0.86 suggested high practical significance for UL motor rehabilitation using the augmented reality system.
System provided promising results for UL motor rehabilitation, since enhancements have been observed in the shoulder range of motion and speed. Implications for Rehabilitation Gain of range of motion of flexion and abduction of the shoulder of post-stroke patients can be achieved through an augmented reality system containing exercises to promote the mental practice. NeuroR system provides a mental practice method combined with visual feedback for motor rehabilitation of chronic stroke patients, giving the illusion of injured upper-limb (UL) movements while the affected UL is resting. Its application is feasible and safe. This system can be used to improve UL rehabilitation, an additional treatment past the traditional period of the stroke patient hospitalization and rehabilitation.
确定基于增强现实技术的系统用于中风患者上肢运动康复的临床可行性。
一名物理治疗师指导参与者在增强现实环境中完成任务，在该环境中他们能像在镜子中一样看到自己和周围环境。进行了两项案例研究。在干预前后对参与者进行评估。第一项研究使用Fugl-Meyer量表评估上肢运动功能。使用非参数符号检验和效应量对数据进行比较。第二项研究使用计算机生物摄影测量法评估肩部前屈和外展的运动范围增益。
在5%的显著性水平下，Fugl-Meyer评分表明增强现实组上肢运动改善的趋势大于另一组。此外，效应量值0.86表明使用增强现实系统进行上肢运动康复具有较高的实际意义。
该系统在上肢运动康复方面取得了有前景的结果，因为在肩部运动范围和速度方面都有改善。康复意义 通过包含促进心理练习的练习的增强现实系统，可以实现中风后患者肩部屈伸和外展运动范围的增加。NeuroR系统为慢性中风患者的运动康复提供了一种结合视觉反馈的心理练习方法，在患侧上肢休息时给人一种患侧上肢运动的错觉。其应用是可行且安全的。该系统可用于改善上肢康复，作为中风患者传统住院和康复期之后的一种额外治疗方法。
