摘要

背景和目的:人到中年,行动能力可能会下降,越来越多的证据表明,在人生的这一阶段对行动能力进行评估非常重要。坐立过程中的智能手机加速度测量已被证明可识别行动障碍,但其在检测中年期细微行动能力衰退方面的效用尚未得到测试。本研究旨在探讨在普通椅子和软垫沙发上进行坐立测试时测量的智能手机加速度数据是否有助于检测中年人行动能力的细微变化:23 名年轻人(25.0 ± 2.5 岁)、25 名中年人(52.0 ± 5.2 岁)和 17 名老年人(70.0 ± 4.1 岁)分别在标准椅子和沙发上进行了 5 次坐立测试。使用安装在参与者下背部的智能手机测量下肢肌肉力量、起立时的最大垂直速度(MVV)、整个任务和从坐到站的过渡阶段(SiToSt)的持续时间,以及使用动态时间扭曲法测量重复变异性:结果:与年轻人相比,中年人的下肢肌肉力量有所下降(5.25 ± 1.08 vs 6.19 ± 1.38 W/kg,p = .034),在沙发上更为明显(6.23 ± 1.61 vs 8.08 ± 2.17 W/kg,p = .004)。只有在沙发上才能发现中年人和年轻人在 MVV(p = .011)和 SiToSt 持续时间(p = .038)方面的差异,与老年人相比,中年人在椅子上的变异性更小(p = .018)。在这两种情况下,中年人组与年轻人或老年人组在总任务持续时间上没有差异:由于天花板效应的影响,大多数普通测试在检测中年早期行动能力衰退方面能力有限。我们的研究结果表明,基于智能手机的 "坐立 "评估在检测中年期细微行动能力下降方面具有潜力,可作为这方面的筛查工具。

Smartphone-Based Sit-to-Stand Analysis for Mobility Assessment in Middle Age.

Background and objectives: Mobility can decline in middle age and growing evidence highlights the importance of assessing mobility at this stage of life. Smartphone-based accelerometry during sit-to-stand has been shown to identify mobility impairments, but its utility in detecting subtle mobility deterioration in middle age has not been tested. This study aimed to examine whether smartphone-based accelerometry data measured during sit-to-stand tests performed on a regular chair and a cushioned sofa could be useful for detecting subtle changes in mobility in middle age.

Research design and methods: Twenty-three young (25.0 ± 2.5 years), 25 middle-aged (52.0 ± 5.2 years), and 17 older adults (70.0 ± 4.1 years) performed the 5-times sit-to-stand test on both a standard chair and a sofa. A smartphone attached to the participants' lower back was used to measure lower-limb muscle power, maximal vertical velocity (MVV) during rising, the duration of the total task and the subphase of transition from sitting to standing (SiToSt), and repetition variability using the dynamic time warping method.

Results: Middle-aged adults had reduced lower-limb muscle power compared to young adults (5.25 ± 1.08 vs 6.19 ± 1.38 W/kg, p = .034), being more pronounced on the sofa (6.23 ± 1.61 vs 8.08 ± 2.17 W/kg, p = .004). Differences between middle-aged and young adults in terms of MVV (p = .011) and SiToSt duration (p = .038) were only detected on the sofa, and the middle-aged adults showed less variability compared to the older adults on the chair (p = .018). There was no difference in total task duration between the middle-aged group and the young or older adults in either condition.

Discussion and implications: Most common tests are limited in their ability to detect early mobility deterioration in midlife due to a ceiling effect. Our results, which show the potential of smartphone-based sit-to-stand assessment in detecting subtle mobility decline in midlife, could serve as a screening tool for this purpose.

期刊介绍: Innovation in Aging, an interdisciplinary Open Access journal of the Gerontological Society of America (GSA), is dedicated to publishing innovative, conceptually robust, and methodologically rigorous research focused on aging and the life course. The journal aims to present studies with the potential to significantly enhance the health, functionality, and overall well-being of older adults by translating scientific insights into practical applications. Research published in the journal spans a variety of settings, including community, clinical, and laboratory contexts, with a clear emphasis on issues that are directly pertinent to aging and the dynamics of life over time. The content of the journal mirrors the diverse research interests of GSA members and encompasses a range of study types. These include the validation of new conceptual or theoretical models, assessments of factors impacting the health and well-being of older adults, evaluations of interventions and policies, the implementation of groundbreaking research methodologies, interdisciplinary research that adapts concepts and methods from other fields to aging studies, and the use of modeling and simulations to understand factors and processes influencing aging outcomes. The journal welcomes contributions from scholars across various disciplines, such as technology, engineering, architecture, economics, business, law, political science, public policy, education, public health, social and psychological sciences, biomedical and health sciences, and the humanities and arts, reflecting a holistic approach to advancing knowledge in gerontology.
