ABSTRACT

This study evaluated whether real-time applied load feedback and a predefined applied load limit improved inter-session reliability and measurement error of passive glenohumeral rotation range-of-motion measurements. Twenty-one male recreational overhead athletes completed two data collection sessions, approximately 1-week apart. Measurements of internal and external rotation range-of-motion and clinician-applied loads were obtained and side-to-side differences were calculated. A load limit of 4 Nm was used for feedback trials. Perception of a capsular end-feel was used for no-feedback trials. Intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs) and minimal detectable changes (MDCs) were derived. ICCs from single trials with and without feedback ranged from 0.72–0.93 and 0.63–0.89, respectively. SEMs ranged from 2.6°-6.1° with feedback and 3.3°-6.0° without feedback. MDCs from single trials with and without feedback ranged from 7.2°-16.8° and 9.1°-16.7°, respectively. Applied load feedback did not improve, already moderate to excellent, inter-session reliability and SEM for passive glenohumeral rotation range-of-motion measurements.

摘要

这项研究评估了实时施加的负荷反馈和预定义的施加负荷极限是否可以改善会话间的可靠性以及被动盂肱旋转运动范围测量的测量误差。21名男性休闲高架运动员完成了两次数据收集会议，大约相隔1周。测量了内部和外部旋转运动范围以及临床医生施加的载荷，并计算了左右差异。反馈试验使用4 Nm的负载极限。无反馈试验使用了对囊终感的感知。得出了类内相关系数（ICC），测量标准误差（SEM）和最小可检测变化（MDC）。来自有和没有反馈的单项试验的ICC范围分别为0.72-0.93和0.63-0.89。扫描电镜的范围为2.6°-6。1°有反馈，而3.3°-6.0°无反馈。来自有和没有反馈的单项试验的MDC范围分别为7.2°-16.8°和9.1°-16.7°。应用的负载反馈并没有提高，已经达到中等到出色的会话间可靠性和SEM，可以进行被动肱骨头旋转运动范围测量。
