Frailty is a clinical condition among older adults defined as the loss of resources in one or more domains (i.e., physical, psychological and social domains) of individual functioning. In frail subjects emergency situations and mobility levels need to be carefully monitored. This study aimed to: i) evaluate differences in the mobility index (MI) provided by ADAMO system, an innovative remote monitoring device for older adults; ii) compare the association of the MI and a traditional physical measure with frailty.
Twenty-five community-dwelling older adults (71 ± 6 years; 60% women) wore ADAMO continuously for a week. The time percentage spent in Low, Moderate and Vigorous Activities was assessed using ADAMO system. Walking ability and frailty were measured using the 400 m walk test and the Tilburg Frailty Indicator, respectively.
Controlling for age and gender, the ANCOVA showed that frail and robust participants were different for Low (frail = 58.8%, robust = 42.0%, p < 0.001), Moderate (frail = 25.5%, robust = 33.8%, p = 0.008), and Vigorous Activity (frail = 15.7%, robust = 24.2%, p = 0.035). Using cluster analysis, participants were divided into two groups, one with higher and one with lower mobility. Controlling for age and gender, linear regression showed that the MI clusters were associated with total (β = 0.571, p = 0.002), physical (β = 0.381, p = 0.031) and social (β = 0.652, p < 0.001) frailty; and the 400 m walk test was just associated with total (β = 0.404, p = 0.043) and physical frailty (β = 0.668, p = 0.002).
ADAMO system seems to be a suitable time tracking that allows to measure mobility levels in a non-intrusive way providing wider information on individual health status and specifically on frailty. For the frail individuals with an important loss of resources in physical domain, this innovative device may represent a considerable help in preventing physical consequences and in monitoring functional status.
虚弱是老年人的一种临床状况，定义为个体功能的一个或多个领域（即身体、心理和社会领域）资源的丧失。在虚弱的受试者中，需要仔细监测紧急情况和移动水平。本研究旨在：i）评估 ADAMO 系统提供的移动指数（MI）的差异，ADAMO 系统是一种用于老年人的创新远程监测设备；ii）比较 MI 与传统物理测量与虚弱的关联。
25 名社区居住的老年人（71±6 岁；60%女性）连续佩戴 ADAMO 一周。使用 ADAMO 系统评估低、中、高强度活动的时间百分比。使用 400 米步行测试和蒂尔堡虚弱指标分别测量行走能力和虚弱程度。
控制年龄和性别，ANCOVA 显示虚弱和健壮参与者在低强度（虚弱=58.8%，健壮=42.0%，p<0.001）、中强度（虚弱=25.5%，健壮=33.8%，p=0.008）和高强度活动（虚弱=15.7%，健壮=24.2%，p=0.035）方面存在差异。使用聚类分析，参与者被分为两组，一组移动性较高，另一组移动性较低。控制年龄和性别，线性回归显示 MI 聚类与总（β=0.571，p=0.002）、身体（β=0.381，p=0.031）和社会（β=0.652，p<0.001）虚弱有关；400 米步行测试仅与总（β=0.404，p=0.043）和身体虚弱（β=0.668，p=0.002）有关。
ADAMO 系统似乎是一种合适的时间跟踪方法，可以非侵入性地测量移动水平，提供关于个体健康状况的更广泛信息，特别是关于虚弱状况。对于身体资源严重丧失的虚弱个体，这种创新设备可能有助于预防身体后果并监测功能状态。
