大多数中风幸存者不得不应对手臂功能的缺陷，这通常是用主观的临床评分来衡量的。本研究的目的是检验画圆度量法是否适用于测量中风幸存者的上肢功能。中风幸存者(n=16)和健康受试者(n=20)在桌面上画了尽可能大和尽可能圆的圆圈。测量关节角度和关节位置。计算圆周面积和圆度，并根据仰角和肘角的同时变化识别协同运动模式。与健康受试者相比，中风幸存者的圆周面积、圆度和关节偏移量的值在统计学上有显著降低。与健康受试者相比，中风幸存者在协同运动模式下的活动明显更多。Fugl-Meyer评分的上肢近端部分与圆周面积、圆度、关节偏移和协同运动模式的使用有很强的相关性。目前的研究表明，在健康受试者和中风幸存者之间，圆圈面积、圆度和协同运动模式的使用在统计学上存在显著差异。这些圆形指标与中风的严重程度密切相关，如FM评分的上肢近端部分所示。在临床实践中，圆形面积和圆度可以为中风存活者的手臂功能提供有用的客观信息。在研究环境中，针对协同运动模式发生的结果测量有助于增加对中风后上肢功能恢复机制的理解。
The majority of stroke survivors have to cope with deficits in arm function, which is often measured with subjective clinical scales. The objective of this study is to examine whether circle drawing metrics are suitable objective outcome measures for measuring upper extremity function of stroke survivors. 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 were measured. Circle area and roundness were calculated, and synergistic movement patterns were identified based on simultaneous changes of the elevation angle and elbow angle. Stroke survivors had statistically significant lower values for circle area, roundness and joint excursions, compared to healthy subjects. 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 scale and circle area, roundness, joint excursions and the use of synergistic movement patterns were found. The present study showed statistically significant differences in circle area, roundness and the use of synergistic movement patterns between healthy subjects and stroke survivors. These circle metrics are strongly correlated to stroke severity, as indicated by the proximal upper extremity part of the FM score. In clinical practice, circle area and roundness can give useful objective information regarding arm function of stroke survivors. In a research setting, outcome measures addressing the occurrence of synergistic movement patterns can help to increase understanding of mechanisms involved in restoration of post stroke upper extremity function.
