目的：运动学评估越来越多地用于上肢机器人辅助训练期间的运动结果测量，除了临床量表。然而，他们的相关性还没有得到评估much.Methods：38例严重亚急性卒中患者（年龄56 +/- 17 [19-87]岁;卒中后时间，55 +/- 22天）进行了16次（平均3次/周，35 +/- 15天）上肢机器人辅助训练结合标准治疗。使用Fugl-Meyer评估量表、运动状态量表（MSS）和运动学测量评估前/后运动表现。结果：训练后，所有患者的临床和运动学结果均得到改善（P < 0.01）。FM评分从17.7 +/- 10.0增加至28.6 +/- 15.4。所有基线运动学测量与临床评分密切相关。临床和运动学变化之间的相关性为中度（FM近端评分变化和准确性测量变化的r = -0.65）。然而，平滑度和准确性指标被证明是响应measures.Conclusion：本研究表明，基线运动学措施和他们的前/后训练的变化显着相关的临床运动结果的措施。然而，即使运动的措施是有效的运动损伤的评价，我们不能建议取代常见的临床措施的运动功能，也评估上肢的功能能力。
Purpose: Kinematic assessments are increasingly used as motor outcome measures during upper limb robot-assisted training, in addition to clinical scales. However, their relevance has not been evaluated much.Methods: Thirty-eight patients with severe sub-acute stroke (age 56 +/- 17 [19-87] years; time since stroke, 55 +/- 22 days) carried out 16 sessions (average 3/week, 35 +/- 15 days) of upper limb robot-assisted training combined with standard therapy. Pre/post motor performance was evaluated using the Fugl-Meyer Assessment scale, Motor Status Scale (MSS) and kinematic measures. Motor outcomes were compared and relationships between clinical and kinematic outcomes were analyzed.Results: All clinical and kinematic outcomes improved after training (p < 0.01). FM score increased from 17.7 +/- 10.0 to 28.6 +/- 15.4. All baseline kinematic measures were strongly correlated with clinical scores. Correlations between clinical and kinematic changes were moderate (r = -0.65 for change in FM Proximal score and change in accuracy measure). However, smoothness and accuracy indicators were shown to be responsive measures.Conclusion: This study demonstrated that baseline kinematic measures and their pre/post training changes were significantly correlated with clinical motor outcome measures. However, even if kinematic measures are valid for the evaluation of motor impairment we cannot propose to substitute common clinical measures of motor function which also evaluate functional abilities of the upper limb.
