Past research has indicated that the dominant arm produces more efficient interactive torque control during multi-joint movements. In addition, a bimanual arm movement study found that the dominant arm produced more circular trajectories during circular drawing movements, particularly during fast speed conditions. The current study serves to determine whether statistical trajectory analysis of circular drawing patterns can be used as an objective indicator of handedness. The experiment involved subjects performing unimanual circle drawing movements in both arms at two different speeds.
