Few established measures allow effective quantification of physical performance in severely injured service members. We sought to establish preliminary normative data in 180 healthy, active-duty service members for physical performance measures that can be readily implemented in a clinical setting. Interrater and test-retest reliability and minimal detectable change (MDC) values were also determined. Physical performance testing included self-selected walking velocity on level and uneven terrain, timed stair ascent, the sit-to-stand five times test, the four-square step test, and the 6-minute walk test. Data analysis included descriptive statistics, intraclass correlation coefficients, and MDC. Interrater and test-retest reliability were excellent for all measures (intraclass correlation coefficients >0.75). MDC values for timed measures were <0.3 seconds for interrater comparisons and <1.5 seconds for between-day comparisons. Physical performance measures had a narrow range of normal performance and were reliable and stable between days.
在严重受伤的军人中，很少有既定的方法可以有效量化身体机能。我们试图为 180 名健康、现役的军人建立身体机能测量的初步规范数据，这些测量方法可以在临床环境中轻易实施。同时，我们还确定了组内相关系数和最小可检测变化值（MDC）。身体机能测试包括在水平和不平坦地形上的自选步行速度、计时楼梯上升、五次坐站测试、四方步测试和 6 分钟步行测试。数据分析包括描述性统计、组内相关系数和 MDC。所有测量方法的组内相关系数均很高（>0.75），表明了极好的组内和组间可靠性。计时测量的 MDC 值在组内比较时<0.3 秒，在两天间比较时<1.5 秒。身体机能测量具有较窄的正常表现范围，在两天之间具有可靠性和稳定性。
