Ja. Jordan et al., Randomly alternating image presentation during laparoscopic training leadsto faster automation to the "fulcrum effect", ENDOSCOPY, 32(4), 2000, pp. 317-321
Background and Study Aims: The aim of this study was to evaluate four train
ing programmes intended to help laparoscopic surgeons automate to the "fulc
rum effect".
Methods: A total of 32 participants (16 men, 16 women), were randomly assig
ned to one of four different image-viewing conditions: full binocular, y-ax
is inverted, normal laparoscopic and randomly alternating (between axis-inv
erted and normal laparoscopic). The subjects were requested to perform 10 t
rials of a simple laparoscopic cutting task, each lasting 2 minutes. Each t
hen completed a 2-minute test under normal laparoscopic imaging conditions.
Results: In the final test trial, participants who trained under the random
ly alternating imaging conditions (y-axis inverted and normal laparoscopic)
performed significantly better than those from the other groups.
Conclusion: Training under a randomly alternating viewing condition helps l
aparoscopic trainees automate to the "fulcrum effect" faster.
