Abstract

BACKGROUND

Exercise has been one of the key strategies for preventing frailty. While training programs for preventing frailty have been mainly developed in person, which have now become difficult to perform due to the coronavirus disease pandemic. It would be worthwhile to explore a feasibility of methods for a remote-based training with information and communications technology (ICT) in the pre-frail/robust older adults living at home.

METHODS

We assessed the feasibility of a remote-based training with ICT device in terms of 1) a measurement accuracy and 2) whether it could be used for remote-based training of different intensities. To evaluate a measurement accuracy of the ICT device, we evaluated an inter-rater reliability between a true score and scores obtaining from the ICT device in 20 participants aged 65 years and older. Intraclass correlation was calculated. To evaluate a feasibility of remote-based training interventions of different intensities, we did a parallel, randomized, active controlled trial. Participants aged 65 years or older were randomly allocated to the two 3-month intervention programs with different intensity of exercise with the ICT (i.e., an Exercise-Intensive program and a Light-load exercise program). The primary outcome was 3-month scores of the 30-s chair-stand test (CS-30), which was compared between two groups using mixed models for repeated measures to account for within-person correlations.

RESULTS

The ICT device showed a high intraclass correlation of over 0.99 for all outcomes including CS-30. Between Aug and Oct 2020, 70 participants (36 and 34 in the Exercise-Intensive and Light-load exercise programs, respectively) were randomized. After 3 months of intervention, CS-30 scores and other physical function improved in both groups. Difference in the 3-month CS-30 scores between two programs was found to be 0.08 (95% confidence interval: - 2.64, 2.79; p = 0.955), which was not statistically significant. No harmful incidents, such as falls, occurred in either group.

CONCLUSION

We showed a remote-based training with ICT device in the older adults living at home was feasible. Further studies are warranted to determine what kind of remote exercise intervention programs is more effective for maintaining a physical performance and, beyond that, preventing frailty.

摘要

背景

运动一直是预防虚弱的关键策略之一。虽然预防虚弱的训练计划主要是在个人层面上进行的，但由于冠状病毒病大流行，现在很难进行。因此，值得探索一种使用信息和通信技术（ICT）在家中进行远程训练的可行性，针对的是处于虚弱前期/健壮的老年人。

方法

我们评估了一种使用 ICT 设备进行远程训练的可行性，具体包括：1）测量准确性，以及 2）它是否可用于不同强度的远程训练。为了评估 ICT 设备的测量准确性，我们在 20 名年龄在 65 岁及以上的参与者中评估了真实分数和 ICT 设备获得的分数之间的评分者间信度。计算了组内相关系数。为了评估不同强度的远程训练干预措施的可行性，我们进行了一项平行、随机、主动对照试验。参与者按年龄分为 65 岁或以上，随机分配到两个为期 3 个月的 ICT 运动干预计划中，运动强度不同（即强化运动计划和轻负荷运动计划）。主要结局指标是 30 秒椅站测试（CS-30）的 3 个月评分，采用混合模型重复测量来比较两组之间的结果，以考虑个体内相关性。

结果

ICT 设备对包括 CS-30 在内的所有结果的组内相关系数均超过 0.99。2020 年 8 月至 10 月期间，70 名参与者（强化运动组和轻负荷运动组各 36 名和 34 名）被随机分配。干预 3 个月后，两组的 CS-30 评分和其他身体功能均有所改善。两个方案的 3 个月 CS-30 评分差值为 0.08（95%置信区间：-2.64，2.79；p=0.955），无统计学意义。两组均未发生跌倒等不良事件。
