From: Dominant hand, non-dominant hand, or both? The effect of pre-training in hand-eye coordination upon the learning curve of laparoscopic intra-corporeal knot tying

Hand-eye coordination (HEC). Group learning curves. Participants performed 69 consecutive repetitions (R0–R68) of the task (G1, with both the dominant hand and the non-dominant hand; G2 with the dominant hand only; G3, none) during phase 1 (P1): R0–R2, phase 2 (P2): R3–R62, phase 3 (P3): R63–R65, phase 4 (P4): none, and phase 5 (P5): R66–R68. The scores were plotted and group learning curves were calculated. In all groups, the two-phase exponential decay model was the best fitting model
