背景跑步机、举升和携带 (TLC) 电池是一种复合功能性能测试，旨在测量军事人群中功能恢复 (FR) 计划的有效性。目的确定各个测试和复合 TLC 电池的有效性、可靠性和最小临床重要差异 (MCID)。方法我们通过平均差异、效应大小和标准化响应方法评估有效性 后FR；以及 TLC 电池和其他既定措施之间的相关性。我们通过关联 FR 前后的分数来评估可靠性。我们使用主成分分析 (PCA) 来创建复合度量。我们通过分布方法和接受者操作曲线分析确定 MCID。结果FR 前后存在显着的平均变化 (p < .001) 和较大的效应量 (0.6–0.8)。测试前和测试后 Spearman 的相关性范围为 0.5 到 0.6。 TLC 电池评分与其他指标之间的 Spearman 相关性很小 (± 0.3–0.4)，但显着 (p < .001)。 PCA 支持使用单组分复合材料。 MCID 是跑步机时间：3 分钟；任务代谢当量：1.5单位；地板到腰部的提升：15 磅；腰部到肩部的提升：10 磅； 40 英尺承载：10 磅；综合得分：6分。 结论二次数据分析为TLC电池在军事人群中使用的有效性和可靠性提供了初步支持。
BackgroundThe treadmill, lift, and carry (TLC) battery is a composite functional performance test created to measure the effectiveness of a functional restoration (FR) program in a military population.PurposeTo determine the validity, reliability, and minimal clinically important differences (MCIDs) of the individual tests and the composite TLC battery.MethodsWe assessed the validity by mean differences, effect sizes, and standardized response means pre- and post-FR; and by correlations between the TLC battery and other established measures. We assessed reliability by correlating pre- and post-FR scores. We used principal component analysis (PCA) to create a composite measure. We determined MCIDs via distribution methods and receiver operator curve analysis.ResultsThere were significant (p < .001) mean changes and large effect sizes (0.6–0.8) pre- to post-FR. Pre- and posttest Spearman’s correlations ranged from 0.5 to 0.6. Spearman’s correlations between TLC battery scores and other measures were small (± 0.3–0.4) and significant (p < .001). PCA supported use of a single-component composite. MCIDs were treadmill time: 3 minutes; metabolic equivalent of task: 1.5 units; floor-to-waist lift: 15 lbs; waist-to-shoulder lift: 10 lbs; 40-foot carry: 10 lbs; and composite score: 6 units.ConclusionThis secondary data analysis provides preliminary support for the validity and reliability of the TLC battery for use in military populations.
