感觉障碍是阻碍中风后运动瘫痪恢复的一个因素。虽然已经提出了几个机器人辅助中风患者偏瘫上肢的练习，很少有研究探讨了改善功能的中风患者感觉障碍，使用机器人辅助训练。在这项研究中，机器人训练的效果进行了比较的偏瘫上肢3例完全感觉丧失和19例非完全感觉丧失的患者。机器人训练，以协助达到运动进行了为期2周的时间内，每周5天，每天1小时，在10个会议。在训练前和训练后，评估Fugl-Meyer评估总分（不包括协调和腱反射）（FMA-总）和FMA肩肘评分（不包括腱反射）（FMA-S/E）。手臂训练机器人在达到运动过程中的到达和路径误差（RE和PE）也进行了评估。在大多数情况下，FMA-total和FMA-S/E评分均有所改善。感觉完全丧失的病例RE和PE评分更差。我们的研究结果表明，运动麻痹是改善机器人训练。然而，改善可以根据躯体感觉反馈的存在或不存在而变化。
Sensory disorder is a factor preventing recovery from motor paralysis after stroke. Although several robot-assisted exercises for the hemiplegic upper limb of stroke patients have been proposed, few studies have examined improvement in function in stroke patients with sensory disorder using robot-assisted training. In this study, the efficacies of robot training for the hemiplegic upper limb of three stroke patients with complete sensory loss were compared with those of 19 patients without complete sensory loss. Robot training to assist reach motion was performed in 10 sessions over a 2-week period for 5 days per week at 1 h per day. Before and after the training, the total Fugl-Meyer Assessment score excluding coordination and tendon reflex (FMA-total) and the FMA shoulder and elbow score excluding tendon reflex (FMA-S/E) were evaluated. Reach and path errors (RE and PE) during the reach motion were also evaluated by the arm-training robot. In most cases, both the FMA-total and the FMA-S/E scores improved. Cases with complete sensory loss showed worse RE and PE scores. Our results suggest that motor paralysis is improved by robot training. However, improvement may be varied according to the presence or absence of somatic sensory feedback.
