The aim of this study was to assess the effectiveness of a multidimensional exercise intervention on improving fall risk deterrent factors, such as overall strength and flexibility in nursing home residents.
A multi-centre, randomized controlled trial was finally utilized in 40 older adults (>65 years) who were randomly allocated to the intervention or the control group (20 subjects in each). The intervention group attended an exercise program twice a week for eight weeks, to improve functional mobility. The control group did not receive any intervention. Measurements before and after intervention included the Hand Grip Strength (HGS) testing, the Sit-to-Stand test (SST), the Back Scratch Test (BST), and the Sit-and-Reach test (SRT).
MANOVA revealed significant time effects, V = 0.336, (6, 33) = 2.78, = 0.027, partial η = 0.336; group effects, V = 0.599, (6, 33) = 8.22, < 0.001, partial η = 0.599; and grouptime interaction, V = 0.908, (6, 33) = 54.52, < 0.001, partial η = 0.908. A subsequent univariate analysis did not reveal a significant time effect for any variable ( > 0.05). Significant group effects were observed only for SRT ( < 0.05). Significant grouptime interactions were observed for all the examined variables ( < 0.05). Dependent t-tests showed that the older adults in the exercise group were significantly improved in all the examined parameters ( < 0.05). Except for SRT ( > 0.05), all the other parameters significantly deteriorated in the control group ( < 0.05).
Significant improvements were demonstrated in strength and flexibility among nursing home residents following an eight-week group exercise training program.
本研究旨在评估多维运动干预对改善养老院居民跌倒风险威慑因素（如整体力量和灵活性）的有效性。
最终对40名65岁以上的老年人进行了一项多中心随机对照试验，他们被随机分配到干预组或对照组（每组20名受试者）。干预组每周参加两次运动计划，为期八周，以改善功能活动能力。对照组未接受任何干预。干预前后的测量包括握力测试（HGS）、坐立测试（SST）、背部抓挠测试（BST）和坐位体前屈测试（SRT）。
多变量方差分析显示出显著的时间效应，V = 0.336，（6, 33） = 2.78，p = 0.027，偏 η = 0.336；组效应，V = 0.599，（6, 33） = 8.22，p < 0.001，偏 η = 0.599；以及组时间交互作用，V = 0.908，（6, 33） = 54.52，p < 0.001，偏 η = 0.908。随后的单变量分析未发现任何变量有显著的时间效应（p > 0.05）。仅在SRT上观察到显著的组效应（p < 0.05）。在所有检查变量上均观察到显著的组时间交互作用（p < 0.05）。相关样本t检验表明，运动组的老年人在所有检查参数上均有显著改善（p < 0.05）。除SRT外（p > 0.05），对照组的所有其他参数均显著恶化（p < 0.05）。
经过为期八周的团体运动训练计划，养老院居民的力量和灵活性有显著改善。
