Home-based exercise programs can improve physical functioning and health status of elderly people. Successful implementation of exercise interventions for older people presents major challenges and supporting elderly people properly while doing their home-based exercises is essential for training success. We developed a tablet-based system-ActiveLifestyle-that offers older adults a home-based strength-balance training program with incorporated motivation strategies and support features.
The goal was to compare 3 different home-based training programs with respect to their effect on measures of gait quality and physical performance through planned comparisons between (1) tablet-based and brochure-based interventions, (2) individual and social motivation strategies, and (3) active and inactive participants.
A total of 44 autonomous-living elderly people (mean 75, SD 6 years) were assigned to 3 training groups: social (tablet guided, n=14), individual (tablet guided, n=13), and brochure (brochure guided, n=17). All groups joined a 12-week progressive home-based strength-balance training program. Outcome measures were gait performance under single and dual task conditions, dual task costs of walking, falls efficacy, and physical performance as measured by the Short Physical Performance Battery (SPPB). Furthermore, active (≥75% program compliance) and inactive (<75% program compliance) individuals were compared based on their characteristics and outcome measures.
The tablet groups showed significant improvements in single and dual task walking, whereas there were no significant changes observable in the brochure group. Between-groups comparisons revealed significant differences for gait velocity (U=138.5; P=.03, r=.33) and cadence (U=138.5, P=.03 r=.34) during dual task walking at preferred speed in favor of the tablet groups. The brochure group had more inactive participants, but this did not reach statistical significance (U=167, P=.06, r=.29). The active participants outperformed the inactive participants in single and dual task walking, dual task costs of walking, and SPPB scores. Significant between-groups differences were seen between the tablet groups and the brochure group, in favor of the tablet groups.
A tablet-based strength-balance training program that allows monitoring and assisting autonomous-living older adults while training at home was more effective in improving gait and physical performance when compared to a brochure-based program. Social or individual motivation strategies were equally effective. The most prominent differences were observed between active and inactive participants. These findings suggest that in older adults a tablet-based intervention enhances training compliance; hence, it is an effective way to improve gait.
居家锻炼计划可以改善老年人的身体机能和健康状况。成功实施针对老年人的锻炼干预面临重大挑战,在老年人进行居家锻炼时给予适当支持对于训练成功至关重要。我们开发了一个基于平板电脑的系统——积极生活方式系统(ActiveLifestyle),为老年人提供一个包含激励策略和支持功能的居家力量平衡训练计划。
目标是通过对以下三组进行计划比较,比较三种不同的居家训练计划对步态质量和身体机能指标的影响:(1)基于平板电脑的干预和基于宣传册的干预;(2)个体激励策略和社交激励策略;(3)积极参与者和不积极参与者。
总共44名独立生活的老年人(平均年龄75岁,标准差6岁)被分配到3个训练组:社交组(平板电脑指导,n = 14)、个体组(平板电脑指导,n = 13)和宣传册组(宣传册指导,n = 17)。所有组都参加了一个为期12周的渐进式居家力量平衡训练计划。结果指标包括单任务和双任务条件下的步态表现、步行的双任务成本、跌倒效能以及通过简短身体机能测试电池(SPPB)测量的身体机能。此外,根据积极(≥75%计划依从性)和不积极(<75%计划依从性)个体的特征和结果指标进行比较。
平板电脑组在单任务和双任务步行方面有显著改善,而宣传册组未观察到显著变化。组间比较显示,在以偏好速度进行双任务步行时,步态速度(U = 138.5;P = 0.03,r = 0.33)和步频(U = 138.5,P = 0.03,r = 0.34)存在显著差异,有利于平板电脑组。宣传册组有更多不积极参与者,但未达到统计学意义(U = 167,P = 0.06,r = 0.29)。积极参与者在单任务和双任务步行、步行的双任务成本以及SPPB评分方面优于不积极参与者。平板电脑组和宣传册组之间存在显著的组间差异,有利于平板电脑组。
与基于宣传册的计划相比,一个基于平板电脑的力量平衡训练计划,在老年人居家训练时能够进行监测并提供协助,在改善步态和身体机能方面更有效。社交或个体激励策略同样有效。在积极参与者和不积极参与者之间观察到最显著的差异。这些发现表明,对于老年人来说,基于平板电脑的干预可提高训练依从性;因此,这是改善步态的有效方法。
