The majority of stroke survivors have to cope with deficits in arm function, which is often monitored with subjective clinical scales during stroke rehabilitation. The aim of this study is to examine whether robotic outcome measures obtained during circle drawing are suitable to objectively measure upper extremity function of stroke survivors, especially regarding synergistic movement patterns. Stroke survivors (n = 16) and healthy subjects (n = 20) drew circles, as big and as round as possible, above a table top. Joint angles and positions of the shoulder and elbow were measured. Synergistic movement patterns were identified based on simultaneous changes of the shoulder elevation angle and elbow angle. Stroke survivors moved significantly more within synergistic movement patterns, compared to healthy subjects. Strong correlations between the proximal upper extremity part of the Fugl-Meyer (FM) scale and the use of synergistic movement patterns were found. The proposed outcome measures seem to be suitable measures to objectively quantify the occurrence of synergistic movement patterns of the upper extremity following stroke.
大多数中风幸存者必须应对手臂功能缺陷，在中风康复期间，通常使用主观临床量表对其进行监测。本研究的目的是检验在画圈过程中获得的机器人测量结果是否适合客观测量中风幸存者的上肢功能，尤其是关于协同运动模式。中风幸存者（n = 16）和健康受试者（n = 20）在桌面上方尽可能大地画尽可能圆的圈。测量了肩部和肘部的关节角度和位置。基于肩部抬高角度和肘部角度的同时变化识别协同运动模式。与健康受试者相比，中风幸存者在协同运动模式内的动作明显更多。发现Fugl-Meyer（FM）量表上肢近端部分与协同运动模式的使用之间存在强相关性。所提出的测量结果似乎是客观量化中风后上肢协同运动模式发生情况的合适测量方法。
