BACKGROUND
With the number of older adults in society rising, frailty becomes an increasingly prevalent health condition. Regular physical activity can prevent functional decline and reduce frailty symptoms. In particular, home-based exercise programs can be beneficial in reducing frailty of older adults and fall risk, and in improving associated physiological parameters. However, adherence to home-based exercise programs is generally low among older adults. Current developments in technology can assist in enlarging adherence to home-based exercise programs. This paper presents the rationale and design of a study evaluating the adherence to and effectiveness of an individually tailored, home-based physical activity program for frail older adults driven by mobility monitoring through a necklace-worn physical activity sensor and remote feedback using a tablet PC.
METHODS/DESIGN: Fifty transitionally frail community-dwelling older adults will join a 6-month home-based physical activity program in which exercises are provided in the form of exercise videos on a tablet PC and daily activity is monitored by means of a necklace-worn motion sensor. Participants exercise 5 times a week. Exercises are built up in levels and are individually tailored in consultation with a coach through weekly telephone contact.
DISCUSSION
The physical activity program driven by mobility monitoring through a necklace-worn sensor and remote feedback using a tablet PC is an innovative method for physical activity stimulation in frail older adults. We hypothesize that, if participants are sufficiently adherent, the program will result in higher daily physical activity and higher strength and balance assessed by physical tests compared to baseline. If adherence to and effectiveness of the program is considered sufficient, the next step would be to evaluate the effectiveness with a randomised controlled trial. The knowledge gained in this study can be used to develop and fine-tune the application of innovative technology in home-based exercise programs.

背景
随着社会中老年人数量的增加，衰弱成为一种日益普遍的健康状况。定期进行体育活动可以预防功能衰退并减轻衰弱症状。特别是，居家锻炼计划有助于降低老年人的衰弱程度和跌倒风险，并改善相关生理参数。然而，老年人对居家锻炼计划的依从性普遍较低。当前的技术发展有助于提高对居家锻炼计划的依从性。本文介绍了一项研究的基本原理和设计，该研究通过佩戴在项链上的身体活动传感器进行移动性监测，并使用平板电脑进行远程反馈，评估针对体弱老年人量身定制的居家体育活动计划的依从性和有效性。
方法/设计：50名处于过渡性衰弱状态的社区居家老年人将参加一项为期6个月的居家体育活动计划，其中锻炼以平板电脑上的锻炼视频形式提供，日常活动通过佩戴在项链上的运动传感器进行监测。参与者每周锻炼5次。锻炼分阶段进行，并通过每周电话联系与教练协商进行个性化定制。
讨论
通过佩戴在项链上的传感器进行移动性监测并使用平板电脑进行远程反馈的体育活动计划，是刺激体弱老年人进行体育活动的一种创新方法。我们假设，如果参与者有足够的依从性，与基线相比，该计划将导致更高的日常身体活动水平，以及通过体能测试评估的更高的力量和平衡能力。如果该计划的依从性和有效性被认为足够，下一步将是通过随机对照试验评估其有效性。本研究中获得的知识可用于开发和微调创新技术在居家锻炼计划中的应用。
