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. Methods 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. Results 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. Conclusions 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
