BackgroundThrough一个太极干预数据集的重新分析，研究的目的是确定，如果有的话，研究样本的亚组证明从intervention. Method-reanalysis的差异效益太极干预研究，随机对照试验在尤金和斯普林菲尔德，俄勒冈州。年龄≥65岁的非体力活动参与者被随机分配到两组之一：太极（n=49）和等待列表对照（n=45）。主要结果指标是自我报告的身体功能。结果初步潜在曲线分析表明太极拳训练效果显着：与对照组相比，太极拳组的参与者报告感知身体功能显着改善。然而，有显着的个体间的变异性在响应太极拳。通过确定两个亚组进一步描述了总体干预效果。这种划分表明，在基线时身体功能水平较低的太极参与者比身体功能评分较高的人从太极训练计划中受益更多。列入额外的措施，在基线的个人特征，运动的信心，和上课出勤率的变化进一步解释了治疗respons.ConclusionsFindings的差异，从这项研究表明，虽然干预可能会显示出整体效果（或没有整体效果），它可能是不同的有效亚组的参与者，在他们的干预前的特点不同。检查结果指标的变异性可以为改进和调整针对特定亚组的适当干预措施提供重要信息。
BackgroundThrough a re-analysis of a Tai Chi intervention data set, the study objective was to determine which, if any, subgroups of the study sample evidenced differential benefits from the intervention.MethodRe-analysis of a Tai Chi intervention study, a randomized controlled trial in Eugene and Springfield, Oregon. Physically inactive participants aged ≥65 years were randomly assigned to one of two groups: Tai Chi (n=49) and a wait-list control (n=45). The main outcome measure was self-reported physical function.ResultsInitial latent curve analyses indicated significant Tai Chi training effects: Participants in the Tai Chi group reported significant improvements in perceived physical function compared to those in the control group. However, there was significant interindividual variability in response to Tai Chi. The overall intervention effect was further delineated by identifying two subgroups. This delineation showed that Tai Chi participants with lower levels of physical function at baseline benefited more from the Tai Chi training program than those with higher physical function scores. Inclusion of additional measures of individual characteristics at baseline, change in movement confidence, and class attendance further explained differences in treatment responses.ConclusionsFindings from this study suggest that although an intervention may show an overall effect (or no overall effect), it may be differentially effective for subgroups of participants that differ in their pre-intervention characteristics. Examination of variability in outcome measures can provide important information for refining and tailoring appropriate interventions targeted to specific subgroups.
