Spatial navigation is a prodromal dementia marker. Exercise used alongside virtual reality improves many cognitive functions, but effects on spatial navigation are still unclear. To investigate the effect of virtual reality-based physical exercise with 2D exergames on spatial navigation in institutionalized non-robust older persons. A total of 14 older persons (aged ≧ 60) were randomly allocated to the exergame (EG) and active control (ACG) groups. EG performed exercises with 2D exergames, while the ACG used the same movements as the EG, but without the use of virtual reality. Spatial navigation was assessed through the Floor Maze Test, where the immediate maze time (IMT) and delayed maze time (DMT) were recorded. Spatial navigation was enhanced in EG participants compared to ACG individuals. A significant ( = 0.01) IMT reduction between groups was observed, while DMT time without prior planning was significantly different at the significance threshold ( = 0.07). Virtual reality-based exercise improves the spatial navigation of institutionalized non-robust older persons. This study should be replicated to confirm the findings reported herein. This study was registered in the Brazilian Registry of Clinical Trials (Protocol RBR-8dv3kg - https://ensaiosclinicos.gov.br/rg/RBR-8dv3kg).
空间导航是前驱性痴呆的一个标志物。与虚拟现实一起使用的运动可改善多种认知功能，但对空间导航的影响仍不清楚。为了研究基于虚拟现实的体育锻炼与二维健身游戏对机构化体弱老年人空间导航的影响。共有14名老年人（年龄≧60岁）被随机分配到健身游戏（EG）组和主动对照组（ACG）。EG组使用二维健身游戏进行锻炼，而ACG组进行与EG组相同的动作，但不使用虚拟现实。通过地板迷宫测试评估空间导航能力，记录即时迷宫时间（IMT）和延迟迷宫时间（DMT）。与ACG组个体相比，EG组参与者的空间导航能力得到增强。观察到两组之间IMT有显著降低（=0.01），而无预先规划的DMT时间在显著性阈值（=0.07）时有显著差异。基于虚拟现实的锻炼可改善机构化体弱老年人的空间导航能力。本研究应重复进行以证实本文报告的结果。本研究已在巴西临床试验注册中心注册（方案RBR-8dv3kg - https://ensaiosclinicos.gov.br/rg/RBR-8dv3kg）。
