BACKGROUND/OBJECTIVES: Physical activity (PA) has significant benefits for older adults. However, the recommended PA is rarely achieved in nursing homes. In this proof of concept study, we assessed whether virtual reality (VR) could help to increase spontaneous PA during a stationary cycling session.
DESIGN
Prospective crossover proof of concept study.
SETTING
Nursinghome.
PARTICIPANTS
Twelve participants (10 men) aged 63-88, able-bodied but with moderate cognitive impairment.
INTERVENTION
TWO stationary cycling sessions with and withoutVR.
MEASUREMENTS
Cycling distance, pedalling duration, average speed, mean pedalling cadence and the modified Borg rating of perceived exertion scale.
RESULTS
Cycling distance and duration were significantly higher in the VR condition. Most participants would rather repeat cycling sessions with VR than without.
CONCLUSION
The use of VR seems feasible to help achieve PA recommendations for able-bodied people living in nursing homes, even with moderate cognitive impairments.
背景/目的：身体活动（PA）对老年人有显著的益处。然而，在养老院中，很少有人能达到推荐的 PA 水平。在这项概念验证研究中，我们评估了虚拟现实（VR）是否有助于在固定自行车运动期间增加自发性身体活动。
设计
前瞻性交叉概念验证研究。
地点
养老院。
参与者
12 名参与者（10 名男性），年龄 63-88 岁，身体健康，但认知功能中度受损。
干预措施
两次固定自行车运动，一次有 VR，一次没有 VR。
测量
骑行距离、踩踏时长、平均速度、平均踩踏频率和改良的 Borg 感知用力量表。
结果
VR 条件下的骑行距离和时长显著更高。大多数参与者更愿意重复有 VR 的自行车运动，而不是没有 VR 的运动。
结论
即使对于认知功能中度受损的居住在养老院中的身体健全的人，使用 VR 似乎是一种可行的方法，可以帮助他们达到 PA 建议。
