To determine the intersession reliability of the Readiness Evaluation during Simulated Dismounted Operations (REDOp), a novel ecologically-based assessment for injured Service Members, provide minimal detectable change values, and normative reference range values. To evaluate the ability to differentiate performance limitations between able-bodied and injured individuals using the REDOp.
Repeated measures design and between group comparison.
Outpatient rehabilitative care setting.
Service Members who were able-bodied (n = 32) or sustained a traumatic lower extremity injury (n = 22).
During the REDOp, individuals walked over variable terrain as speed and incline progressively increased; they engaged targets; and carried military gear.
Endurance measured using total distance traveled; walking stability measured using range of full-body angular momentum; and shooting accuracy, precision, reaction time and acquisition time.
Intersession reliability analyses were conducted on a sub-group of 18 able-bodied Service Members. Interclass correlation coefficient values were calculated for distance traveled (0.91), range of angular momentum about three axes (0.78-0.93), shooting accuracy (0.61), precision (0.47), reaction time (0.21), and acquisition time (0.77). Service Members with lower extremity injury demonstrated significantly less distance traveled with a median distance of 0.89 km compared to 2.73 km for the able-bodied group (p < 0.001). Service Members with lower extremity injury demonstrated significantly less stability in the frontal and sagittal planes than the able-bodied group (p < 0.001). The primary performance limiter was endurance followed by pain for both groups. There was no evidence of ceiling effects.
The REDOp is a highly reliable, military-relevant assessment that can be used to measure performance and identify deficits across the domains of activity tolerance, gait stability, and shooting performance.
确定模拟下车操作准备评估（REDOp）的会话间可靠性，这是一种新的基于生态学的对受伤军人的评估方法，提供最小可检测变化值和规范参考范围值。评估使用 REDOp 区分健全者和受伤者之间表现局限性的能力。
重复测量设计和组间比较。
门诊康复治疗环境。
健全者（n = 32）或下肢创伤性损伤者（n = 22）。
在 REDOp 中，个体在速度和坡度逐渐增加的情况下在不同地形上行走；他们接触目标；并携带军用装备。
使用总行驶距离测量耐力；使用全身角动量范围测量行走稳定性；以及射击准确性、精度、反应时间和获取时间。
对 18 名健全者进行了会话间可靠性分析。计算了距离行驶（0.91）、三个轴的角动量范围（0.78-0.93）、射击准确性（0.61）、精度（0.47）、反应时间（0.21）和获取时间（0.77）的组内相关系数值。下肢损伤的军人行驶距离明显较少，中位数为 0.89 公里，而健全组为 2.73 公里（p < 0.001）。下肢损伤的军人在额状面和矢状面的稳定性明显低于健全组（p < 0.001）。主要的表现限制因素是耐力，其次是疼痛，两组均如此。没有证据表明存在天花板效应。
REDOp 是一种高度可靠的、与军事相关的评估方法，可用于测量表现并识别活动耐量、步态稳定性和射击表现等领域的缺陷。
