Various authors have described pre and post testing improvements in upper limb coordination as a result of intensive upper limb interventions. While the ability to alter coordination patterns as a result of repetitive hand-arm movement is established, patterns of change in the relationship between proximal and distal effectors of the UE over the course of multiple sessions of training have not been described in the rehabilitation literature. In this study eight subjects (5 male, 3 female) with a mean age of 56.4 years (SD=14.2) and a mean time since CVA of 54.7 months post-stroke (SD=51.7) were trained for eight, 2-3 hour sessions on four robotically facilitated virtual rehabilitation activities. This paper will present 1) Functional performance and pre and post testing kinematic analysis for the eight subjects 2) More extensive analysis of the change in hand and arm coordination over the course of the eight session intervention demonstrated by one of the subjects from this sample 3) Kinematic analysis of another subject from this sample performing an un-trained reaching and grasping activity, before and after training.
多位作者描述了由于强化上肢干预，上肢协调性在测试前后得到改善。虽然重复性手臂运动能够改变协调模式这一点已得到证实，但在康复文献中，尚未描述在多节训练课程过程中上肢近端和远端效应器之间关系的变化模式。在本研究中，对8名受试者（5名男性，3名女性）进行了训练，他们的平均年龄为56.4岁（标准差=14.2），卒中后平均时间为54.7个月（标准差=51.7），在四个机器人辅助的虚拟康复活动上进行了八节、每次2 - 3小时的训练。本文将呈现：1）这8名受试者的功能表现以及测试前后的运动学分析；2）对该样本中的一名受试者在八节干预课程过程中手部和手臂协调性变化的更广泛分析；3）对该样本中的另一名受试者在训练前后进行未训练的伸手抓握活动的运动学分析。
