To gain first insight into the effectiveness of a home-based exercise programme for pre-frail older adults with independent use of novel ICT technology. A pilot study. Forty pre-frail older adults joined a six-month home-based exercise programme using a tablet PC for exercise administration and feedback, and a necklace-worn motion sensor for daily physical activity registration. Participants received weekly telephone supervision during the first 3 months and exercised independently without supervision from a coach during the last 3 months. Functional performance and daily physical activity were assessed at baseline, after three and 6 months. Twenty-one participants completed the programme. Overall, functional performance showed positive results varying from (very) small to large effects (Cohen’s d 0.04–0.81), mainly during the supervised part of the intervention. Regarding daily physical activity, a slight improvement with (very) small effects (Cohen’s d 0.07–0.38), was observed for both self-reported and objectively measured physical activity during the supervised period. However, during the unsupervised period this pattern only continued for self-reported physical activity. This pilot study showed positive results varying from (very) small to large effects in levels and maintenance of functional performance and daily physical activity, especially during the supervised first 3 months. Remote supervision seems to importantly affect effectiveness of a home-based exercise programme. Effectiveness of the programme and the exact contribution of its components should be further quantified in a randomized controlled trial. Home-based exercising using novel technology may be promising for functional performance and physical activity improvement in (pre-frail) older adults.

在平板电脑应用程序和移动监测的推动下，针对体弱前老年人量身定制的家庭锻炼计划的有效性：一项试点研究

通过独立使用新型 ICT 技术，初步了解针对体弱前老年人的家庭锻炼计划的有效性。一项试点研究。四十名体弱的老年人参加了为期六个月的家庭锻炼计划，使用平板电脑进行锻炼管理和反馈，并使用佩戴项链的运动传感器进行日常身体活动登记。参与者在前 3 个月内每周接受电话监督，并在过去 3 个月内在没有教练监督的情况下独立锻炼。在基线、3 个月和 6 个月后评估功能表现和日常体力活动。21 名参与者完成了该计划。总体而言，功能表现显示出积极的结果，从（非常）小到大的影响（Cohen's d 0.04-0.81），主要是在干预的监督部分。关于日常体力活动，在监督期间自我报告和客观测量的体力活动都观察到了轻微的改善和（非常）小的影响（Cohen's d 0.07-0.38）。然而，在无人监督期间，这种模式仅在自我报告的身体活动中继续存在。这项试点研究显示了积极的结果，在功能表现和日常体育活动的水平和维持方面，从（非常）小到大不等，尤其是在受监督的前 3 个月内。远程监督似乎对家庭锻炼计划的有效性有重要影响。该计划的有效性及其组成部分的确切贡献应在随机对照试验中进一步量化。使用新技术的家庭锻炼可能有望改善（体弱前）老年人的功能表现和身体活动。荷兰试验注册（NTR）；试用号 NL4049。该研究是前瞻性注册的（注册日期为 14/11/2013）。
