This study evaluated the validity and reliability of the TecnoBody D-Wall system in assessing joint range of motion (ROM) during overhead squat movements in healthy individuals, using Kinovea as a reference tool for data comparison. A total of 29 participants (16 males, 13 females) with a mean age of 28.41 ± 6.66 years were included. Measurements were conducted for hip and knee joint angles in the sagittal plane, with three repetitions per participant analyzed using both systems. The D-Wall system employed a 3D Kinect V2 camera and force platform, while Kinovea used 2D video-based motion analysis. The results demonstrated excellent agreement between the two systems, with intra-class correlation coefficients (ICC) ranging from 0.79 to 0.99. For the knee joint, the test-retest ICC values were 0.99 (95% CI: 0.97-0.99) for Kinovea and 0.98 (95% CI: 0.95-0.99) for the D-Wall on the right side, and 0.98 (95% CI: 0.97-0.99) for Kinovea and 0.88 (95% CI: 0.79-0.94) for the D-Wall on the left side. For the hip joint, test-retest ICC values were 0.99 (95% CI: 0.97-0.99) for Kinovea and 0.94 (95% CI: 0.88-0.97) for the D-Wall on the right side, and 0.98 (95% CI: 0.97-0.99) for Kinovea and 0.93 (95% CI: 0.87-0.97) for the D-Wall on the left side. Bland-Altman plots confirmed good agreement, with no significant systematic bias observed. Both systems showed statistically insignificant differences ( > 0.05) between measurements, and correlation values ranged from 0.83 to 0.99, indicating strong associations. These findings highlight the high validity and reliability of both TecnoBody D-Wall and Kinovea systems in measuring joint angles during dynamic movements. The comparable accuracy between systems suggests that either system can be effectively utilized in clinical or research settings, depending on specific needs and resource availability.
本研究评估了TecnoBody D-Wall系统在评估健康个体头顶深蹲动作期间关节活动范围（ROM）时的有效性和可靠性，使用Kinovea作为数据比较的参考工具。共纳入29名参与者（16名男性，13名女性），平均年龄为28.41±6.66岁。对矢状面的髋关节和膝关节角度进行测量，每位参与者的三次重复测量均使用这两种系统进行分析。D-Wall系统采用3D Kinect V2摄像头和测力平台，而Kinovea使用基于2D视频的运动分析。结果表明，两种系统之间具有极佳的一致性，组内相关系数（ICC）范围为0.79至0.99。对于膝关节，右侧Kinovea的重测ICC值为0.99（95%CI：0.97 - 0.99），D-Wall为0.98（95%CI：0.95 - 0.99）；左侧Kinovea的重测ICC值为0.98（95%CI：0.97 - 0.99），D-Wall为0.88（95%CI：0.79 - 0.94）。对于髋关节，右侧Kinovea的重测ICC值为0.99（95%CI：0.97 - 0.99），D-Wall为0.94（95%CI：0.88 - 0.97）；左侧Kinovea的重测ICC值为0.98（95%CI：0.97 - 0.99），D-Wall为0.93（95%CI：0.87 - 0.97）。Bland-Altman图证实了良好的一致性，未观察到显著的系统偏差。两种系统在测量之间均显示出无统计学意义的差异（>0.05），相关值范围为0.83至0.99，表明相关性很强。这些发现突出了TecnoBody D-Wall和Kinovea系统在动态运动期间测量关节角度方面的高有效性和可靠性。系统之间可比的准确性表明，根据具体需求和资源可用性，任一系统均可在临床或研究环境中有效使用。
