背景。运动分析是客观评估运动的有力方法，越来越多地被用作中风后的结果测量。关于运动学测量的实际运动性能与常见的传统评估量表之间的关系，我们知之甚少。本研究的目的是确定饮酒后的运动运动学与中风后的损伤或活动限制水平之间的关系。方法。采用运动学分析方法对30例脑卒中患者的运动时间、运动平滑度、肘部和躯干位移（TD）角速度进行了测量。用Fugl-Meyer评估（FMA）评估感觉运动障碍，用行动研究臂测试（ARAT）评估活动能力限制，用ABILHAND问卷评估自我感知活动困难。结果。反向多元回归显示，运动平滑度（类似于运动时间）和TD共同解释了ARAT总方差的67%。这两个变量分别贡献了37%和11%。在FMA中，仅TD就解释了20%的方差，在ABILHAND中，运动平滑解释了6%的方差。结论。在饮酒任务中获得的运动学运动表现测量与活动能力的关系比与损伤的关系更强。运动的平稳性和时间，可能连同躯干的代偿性运动，是衡量活动能力的有效指标，可以被认为是评估中风后上肢功能的关键变量。这些增加的知识对于在临床研究中更好地解释和应用运动学数据具有重要价值。
Background. Kinematic analysis is a powerful method for an objective assessment of movements and is increasingly used as an outcome measure after stroke. Little is known about how the actual movement performance measured with kinematics is related to the common traditional assessment scales. The aim of this study was to determine the relationships between movement kinematics from a drinking task and the impairment or activity limitation level after stroke. Methods. Kinematic analysis of movement performance in a drinking task was used to measure movement time, smoothness, and angular velocity of elbow and trunk displacement (TD) in 30 individuals with stroke. Sensorimotor impairment was assessed with the Fugl-Meyer Assessment (FMA), activity capacity limitation with the Action Research Arm Test (ARAT), and self-perceived activity difficulties with the ABILHAND questionnaire. Results. Backward multiple regression revealed that the movement smoothness (similarly to movement time) and TD together explain 67% of the total variance in ARAT. Both variables uniquely contributed 37% and 11%, respectively. The TD alone explained 20% of the variance in the FMA, and movement smoothness explained 6% of the variance in the ABILHAND. Conclusions. The kinematic movement performance measures obtained during a drinking task are more strongly associated with activity capacity than with impairment. The movement smoothness and time, possibly together with compensatory movement of the trunk, are valid measures of activity capacity and can be considered as key variables in the evaluation of upper-extremity function after stroke. This increased knowledge is of great value for better interpretation and application of kinematic data in clinical studies.
