Individualized feedback-based virtual reality (IFVR) exercise is gaining attention as a cost-effective self-management strategy, however little is known about whether older adults themselves perceive IFVR exercise effective in improving their health. Therefore, we studied the effect of IFVR exercise on health-related quality of life (HRQoL) in older women.
Fifty-four older women aged ≥65 years were randomized to either IFVR exercise group (IFVRG, n=26) or group-based exercise group (GG, n=28). Both groups received a 60-min intervention three times a week for eight weeks. The Short-Form Health Survey (SF-36) was administered. To identify the possible placebo effect, 30-Second Chair Stand Test (30SCST), 8-Foot Up-and-Go Test (8FUGT), and 2-Minute Step Test (2MST) were also administered.
intention-to-treat analysis with adjustment for baseline levels revealed that IFVRG showed greater improvement in mental health (p=0.029) and lower body strength (p=0.042), compared to GG. Within-group analysis for HRQoL revealed that IFVRG showed an increase in role-physical (p=0.015), bodily pain (p=0.017), general health (p=0.004), vitality (p=0.010), role-emotional (p=0.007), and mental health (p<0.001), whereas GG showed an increase in role-physical (p=0.022), general health (p=0.023), and social functioning (p = 0.023). Both groups showed an increase in 30SCST, 2MST and 8FUGT (all p<0.001).
IFVR exercise improved HRQoL in older women, in addition to improving physical fitness. Therefore, it might be recommended to older women as an effective self-management strategy.
基于个性化反馈的虚拟现实（IFVR）运动作为一种具有成本效益的自我管理策略正受到关注，然而，对于老年人自身是否认为IFVR运动对改善健康有效，人们知之甚少。因此，我们研究了IFVR运动对老年女性健康相关生活质量（HRQoL）的影响。
54名年龄≥65岁的老年女性被随机分为IFVR运动组（IFVRG，n = 26）或团体运动组（GG，n = 28）。两组均每周接受3次60分钟的干预，共8周。进行了简短健康调查问卷（SF - 36）。为了确定可能的安慰剂效应，还进行了30秒坐立测试（30SCST）、8英尺起走测试（8FUGT）和2分钟踏步测试（2MST）。
对基线水平进行调整的意向性分析显示，与GG组相比，IFVRG组在心理健康（p = 0.029）和下肢力量（p = 0.042）方面有更大改善。HRQoL的组内分析显示，IFVRG组在角色 - 身体（p = 0.015）、身体疼痛（p = 0.017）、总体健康（p = 0.004）、活力（p = 0.010）、角色 - 情感（p = 0.007）和心理健康（p < 0.001）方面有所提高，而GG组在角色 - 身体（p = 0.022）、总体健康（p = 0.023）和社会功能（p = 0.023）方面有所提高。两组在30SCST、2MST和8FUGT方面均有所增加（所有p < 0.001）。
IFVR运动除了改善身体素质外，还改善了老年女性的HRQoL。因此，它可能作为一种有效的自我管理策略推荐给老年女性。
