AimsUsing的可靠的变化指数（RCI），我们的目的是检查一个多成分的锻炼计划对个人level.MethodsOverall的效果，270名成年人（平均年龄，78岁）完成了一个多成分的体育锻炼计划（力量，有氧，步态，平衡）为40分钟，每周1-2次，持续到1年在日托中心。使用握力、踝关节、膝关节和髋关节力量、计时起身和行走（TUG）、贝格平衡量表（BBS）、步态速度和6分钟步行距离评估有效性。在基线时和此后每3个月测量一次。我们使用每个参与者两个时间点（基线和3、6、9或12个月）之间的数据计算RCI，然后计算参与者的平均RCI值。配对t检验也被用来评估干预的效果作为一个平均为基础的statistics.ResultsThe最高的平均RCI值是踝关节跖屈强度，其次是步态速度，髋关节外展力量，BBS，膝伸肌力量，6分钟步行距离，握力，最后TUG。配对t检验还显示踝关节跖屈强度（0.504）、步态速度（0.413）、髋关节外展强度（0.374）、BBS（0.334）、膝伸肌强度（0.264）和6分钟步行距离（0.248）的中等效应量显著改善。TUG（0.183）。ConclusionThe RCI是一种比较不同评估之间效果的方便方法，特别是在个体水平上。这个指数可以应用于个人反馈的使用。
AimsUsing the reliable change index (RCI), we aimed to examine the effect of a multicomponent exercise program on the individual level.MethodsOverall, 270 adults (mean age, 78 years) completed a multicomponent physical exercise program (strength, aerobic, gait, and balance) for 40 min, 1–2 times per week, continued up to 1 year at a daycare center. Effectiveness was assessed using grip, ankle, knee, and hip strength; Timed Up & Go (TUG); Berg Balance Scale (BBS); gait speed; and 6-min walking distance. These were measured at baseline and every 3 months thereafter. We calculated the RCI using the data between two-time points (baseline and at 3, 6, 9, or 12 months) in each participant and then calculated the mean RCI value across the participants. A paired t-test was also employed to evaluate the effect of the intervention as an average-based statistics.ResultsThe highest mean RCI values were on ankle plantar-flexion strength, followed by gait speed, hip abduction strength, BBS, knee extensor strength, 6-min walk distance, grip strength, and finally TUG. Paired t-test also revealed significant improvement with moderate effect sizes for ankle plantar-flexion strength (0.504), gait speed (0.413), hip abduction strength (0.374), BBS (0.334), knee extensor strength (0.264), and 6-min walk distance (0.248). Significant but small effect size was seen on TUG (0.183).ConclusionThe RCI is a convenient method of comparing the effect between different assessments, especially at an individual level. This index can be applied to the use of personal feedback.
