三维动作捕捉分析系统COFT-Motion■评估健康受试者上肢主动关节活动度的信效度研究

Reliability and validity of the three-dimensional motion capture analysis system COFTMotion■in evaluating the active range of motion of upper limbs in healthy subjects

目的评价三维动作捕捉分析系统COFT-Motion■评估健康受试者上肢主动关节活动度的信效度,为其临床应用提供客观依据。方法2022年1-3月公开招募健康受试者入组。由评估者对健康受试者应用三维动作捕捉分析系统COFT-Motion■和角度尺评测肩关节(前屈、后伸、内收、外展)和肘关节(屈曲、伸直)的主动关节活动度。采用Pearson相关分析评价效度,采用组内相关系数(intraclass correlation coefficient,ICC)评价信度。结果COFT-Motion■与角度尺评估健康受试者上肢主动关节活动度测量值呈正相关,肩关节(前屈、后伸、内收、外展)和肘关节(屈曲、伸直)主动关节活动度的Pearson相关系数分别为0.913、0.964、0.961、0.941、0.864、0.919(P<0.05)。不同评估者使用COFT-Motion■评估健康受试者肩关节(前屈、后伸、内收、外展)和肘关节(屈曲、伸直)主动关节活动度的结果显示,ICC分别为0.892、0.942、0.961、0.988、0.989、0.928(P<0.05);同一评估者重复评测的结果显示,ICC分别为0.795、0.916、0.900、0.868、0.918、0.911(P<0.05)。结论三维动作捕捉分析系统COFT-Motion■应用于健康受试者中具有较好的效度与信度,但鉴于研究样本量和受试对象有限,该系统的进一步推广应用仍需更深入探讨。

Objective To evaluate the reliability and validity of the three-dimensional motion capture analysis system COFT-Motion■in evaluating the active range of motion of upper limbs in healthy subjects,and provide objective basis for its clinical application.Methods From January to March 2022,healthy subjects were publicly recruited for enrollment.The evaluator applied the three-dimensional motion capture analysis system COFT-Motion■and angle ruler to evaluate the active range of motion of the shoulder joint(flexion,extension,adduction,abduction)and elbow joint(flexion,extension)in healthy subjects.Pearson correlation analysis was used to evaluate validity,and intraclass correlation coefficient(ICC)was used to evaluate reliability.Results There was a positive correlation between the measurements of COFT-Motion■and the angle ruler of the active range of motion of upper limbs in healthy subjects.The Pearson correlation coefficients for active range of motion of the shoulder joint(flexion,extension,adduction,abduction)and elbow joint(flexion,extension)were 0.913,0.964,0.961,0.941,0.864,and 0.919,respectively(P<0.05).The results of using COFT-Motion■by different evaluators to evaluate the active range of motion of healthy subjects’shoulder joints(flexion,extension,adduction,abduction)and elbow joints(flexion,extension)showed that the ICC values were 0.892,0.942,0.961,0.988,0.989,and 0.928,respectively(P<0.05).The results of repeated evaluations by the same evaluator showed that the ICC values were 0.795,0.916,0.900,0.868,0.918,and 0.911,respectively(P<0.05).Conclusion The application of the three-dimensional motion capture analysis system COFT-Motion■in healthy subjects has good validity and reliability.However,due to the limited sample size and subject of the study,further promotion and application of the system still need to be further explored.
