摘　　要：目的 采用三维运动学分析方法研究正常人和偏瘫患者在日常生活活动（ADL）中的上肢运动学特点.方法 应用Vcion运动捕捉系统（简称Vicon系统）采集15名正常人（健康组）和10例偏瘫患者（偏瘫组）在执行抬臂、梳头、喝水、摸对侧肩、摸后口袋这5项ADL时的上肢关节三维运动数据.经数据处理得到2组的胸锁关节、肩锁关节、肩关节、肘关节、腕关节的三维运动角度和各动作的运动时间,并进行比较.结果 偏瘫组胸锁关节旋外和外展角度,肩锁关节旋内和后伸角度,肘关节屈曲角度较健康组均显著增大,差异有统计学意义（P〈0.05）,而其肩锁关节内收角度,肩关节内收、外展、前屈、后伸、旋外和旋内角度较健康组则显著减小,差异有统计学意义（P〈0.05）;偏瘫组运动时间较健康组显著延长,差异有统计学意义（P〈0.05）.结论 初步建立了一种基于Vicon系统的上肢三维运动学分析方法,所得结果提示偏瘫患者采用与正常人不同的关节运动模式来完成ADL.Objective To study the kinematic characteristics of normal subjects and hemiplegic patients in activities of daily living （ADL） by three-dimensional （3D） kinematic analysis. Methods A Vicon motion capture system was used to record 3D kinematic data on 15 normal subjects （ the healthy group） and 10 hemiparetic patients （the hemiplegic group） performing 5 ADL tasks： reaching up, combing, drinking, touching the opposite shoulder and touching the back pocket. The movement times and the 3D motion angles of the sternoclavicular joint,the acromioclavicular joint, the shoulder joint, the elbow joint and the wrist joint were recorded. Three-dimensional joint angles and movement times were compared between the normal group and the hemiplegic group. Results Compared with the normal group, the hemiplegic group had significantly more lateral rotation and abduction of the sternoclavicular joint, medial rotation and extension of the acromioclavicular joint and flexion of the elbow joint.The hemiplegics used significantly less medial rotation of the sternoclavicular joint and adduction/abduction, flexion/extension and lateraL/medial rotation of the shoulder joint. Additionally, the hemiplegic group showed significantly longer movement times. Conclusion Hemiplegics use different joint motor patterns from healthy subjects in completing ADL actions.
