An assessment of protocol reliability is an essential step prior to human subject testing for injury prevention. The purpose of this study was to examine the inter-rater and intra-rater reliability of a portable cervical range of motion and isometric strength protocol designed for special forces combat soldiers who are at risk for cervical spine pain and injury due to exposure to head-supported mass. Eight individuals were tested three times to assess reliability, the standard error of the measurement (SEM), and the minimal detectable change across six range of motion measures and six strength measures of the cervical spine. One tester tested all participants twice for intra-rater reliability, and a second tester assessed the participants to examine inter-tester reliability. All reliability measures demonstrated good to excellent reliability (ICC = 0.70-0.96 (isometric strength); ICC = 0.85-0.94 (range of motion)). All SEM scores were 12% or lower for all reliability measures. The findings of this study demonstrate that the protocol developed for a longitudinal multi-site study is reliable and appropriate to implement for injury prevention in military personnel.
在针对预防损伤进行人体受试者测试之前，评估方案的可靠性是必不可少的一步。本研究的目的是检验一种为特种部队战斗士兵设计的便携式颈椎活动范围和等长肌力方案的评分者间信度和评分者内信度，这些士兵因头部承受重量而有颈椎疼痛和损伤的风险。对8名个体进行了三次测试，以评估六种颈椎活动范围测量指标和六种肌力测量指标的可靠性、测量标准误差（SEM）以及最小可检测变化。一名测试者对所有参与者进行了两次测试以评估评分者内信度，另一名测试者对参与者进行评估以检验测试者间信度。所有可靠性指标均显示出良好到优秀的信度（组内相关系数ICC = 0.70 - 0.96（等长肌力）；ICC = 0.85 - 0.94（活动范围））。所有可靠性指标的SEM分数均为12%或更低。本研究结果表明，为纵向多地点研究制定的方案可靠且适用于军事人员的损伤预防。
