The anatomy of the pelvis may obscure differences in pelvic tilt, potentially underestimating its correlation with clinical measures. Measuring the total sagittal range of pelvic movement can serve as a reliable indicator of pelvic function. This study assessed the inter- and intra-examiner reliability of the Kinovea version 0.9.5 and its agreement with the Qualisys System (3D motion capture) for measuring the total pelvic range of movement (ROM) in the sagittal plane, establishing Kinovea's validity in standing and sitting positions with 45° of hip flexion. A cross-sectional study was conducted with 13 asymptomatic participants. Pelvic kinematics were recorded using both systems. Pelvic posture, anterior and posterior tilt, and total pelvic ROM in the sagittal plane were analyzed. The Intraclass Correlation Coefficient (ICC) was used to evaluate reliability and validity. Additionally, the technical error of measurement (TEM), relative TEM, standard error of measurement, and minimal detectable change (MDC) were calculated to establish Kinovea's accuracy. Kinovea demonstrated excellent inter- and intra-examiner reliability for total pelvic ROM in standing and sitting measurements (ICC > 0.90), with relative TEM values below 10% and MDC values between 1.60°and 11.20°. Validity showed good-to-excellent ICC values when comparing Kinovea and the Qualisys System. This finding suggests that Kinovea is a valid tool for obtaining reproducible measurements of total pelvic ROM in the sagittal plane in standing and sitting positions, demonstrating excellent-to-good inter- and intra-examiner reliability for pelvic kinematics.
骨盆的解剖结构可能会掩盖骨盆倾斜度的差异，从而有可能低估其与临床指标的相关性。测量骨盆运动的矢状面总范围可作为骨盆功能的可靠指标。本研究评估了Kinovea 0.9.5版本在测量骨盆矢状面运动总范围（ROM）时，检查者间和检查者内的可靠性，以及它与Qualisys系统（三维运动捕捉）的一致性，确立了Kinovea在髋关节屈曲45°的站立位和坐位时的有效性。对13名无症状参与者进行了一项横断面研究。使用这两种系统记录骨盆运动学数据。分析骨盆姿势、前后倾斜度以及矢状面的骨盆ROM。采用组内相关系数（ICC）评估可靠性和有效性。此外，还计算了测量技术误差（TEM）、相对TEM、测量标准误差和最小可检测变化（MDC），以确定Kinovea的准确性。Kinovea在站立位和坐位测量骨盆ROM时，显示出检查者间和检查者内的出色可靠性（ICC>0.90），相对TEM值低于10%，MDC值在1.60°至11.20°之间。在比较Kinovea和Qualisys系统时，有效性显示出良好至出色的ICC值。这一发现表明，Kinovea是一种有效的工具，可用于在站立位和坐位获取骨盆矢状面运动总范围的可重复测量结果，在骨盆运动学方面显示出出色至良好的检查者间和检查者内可靠性。
