EVENTS
Four primary performance metrics were recorded from each of the Baseline, Post and Retention laparoscopic evaluations. The Time to Complete (TTC) each task was determined from the time the instruments were inserted into the laparoscopic box trainer to either the time when they were removed after completing the task or when 10 min had expired. The Distance Travelled metric described the total distance each implement travelled between the time of insertion and either the time of removal or the expiry of the 10-min time limit. The average velocity of each implement was recorded between the start and end of each task as was the number of excessive velocity events, calculated as the number of instances that the instantaneous velocity of an implement exceeded two standard deviations of the average velocity.
