The authors compared the effects of a standard strength and endurance intervention with a standard plus timing and coordination training intervention on community mobility measured using global positioning systems (GPS) among community-dwelling older adults in this secondary analysis of a randomized controlled trial.
Participants were randomized to a standard or a standard plus timing and coordination training program. Community mobility was measured using the Life Space Assessment (LSA) and GPS indicators of community mobility at baseline, as well as at 12 (immediately after the intervention), 24, and 36 weeks. Linear mixed models were used for analysis.
There were 166 participants with GPS data at baseline, including 81 in the standard plus group and 85 in the standard group. The groups did not differ in participant characteristics or GPS measures at baseline. There were no significant within-group changes in GPS indicators of community mobility or LSA score over time, nor between-group differences of the same.
There were no significant changes in community mobility with either intervention or between-intervention differences. These findings suggest that interventions targeting physical function alone may not be sufficient to improve community mobility or participation in older adults. Future research should focus on the development of multifaceted interventions targeted to improve real-world participation.
The studied interventions did not significantly change community mobility measured using GPS-derived community mobility measures or self-report measures in older adults, suggesting that more comprehensive interventions may be needed to target improvements in community mobility.
本研究通过二次分析随机对照试验，比较了标准强度和耐力干预与标准加定时和协调训练干预对社区居住的老年人使用全球定位系统（GPS）测量的社区移动能力的影响。
参与者被随机分配到标准或标准加定时和协调训练计划中。在基线、12 周（干预后立即）、24 周和 36 周时，使用生活空间评估（LSA）和 GPS 指标来测量社区移动能力。采用线性混合模型进行分析。
共有 166 名参与者具有基线 GPS 数据，其中标准加时组 81 人，标准组 85 人。两组在参与者特征或基线 GPS 测量方面没有差异。GPS 指标和 LSA 评分在时间上均无显著的组内变化，组间也无差异。
两种干预措施均未显著改变 GPS 衍生的社区移动能力或自我报告的社区移动能力，这表明仅针对身体功能的干预措施可能不足以改善老年人的社区移动能力或参与度。未来的研究应集中在开发针对提高现实参与度的多方面干预措施上。
本研究中的干预措施并未显著改变使用 GPS 衍生的社区移动能力或自我报告的社区移动能力来衡量的社区移动能力，这表明可能需要更全面的干预措施来提高社区移动能力。
