Background |
Enhancing cognitive load while performing a bimanual surgical task affects performance. Whether repeated training under this condition could benefit performance in an operating room was tested using a virtual reality simulator with cognitive load applied through two-digit math multiplication questions.
Method |
11 subjects were randomized to Control, VR and VR + CL groups. After a pre-test, VR and VR + CL groups repeated the peg transfer task 150 times over 15 sessions with cognitive load applied only for the last 100 trials. After training, all groups took a post-test and two weeks later the retention test with and without cognitive load and the transfer task on a pig intestine of 150 cm long under cognitive load.
Results and conclusion |
Mixed ANOVA analysis showed significant differences between the control and VR and VR + CL groups (p = 0.013, p = 0.009) but no differences between the VR + CL and the VR groups (p = 1.0). GOALS bimanual dexterity score on transfer test show that VR + CL group outperformed both Control and VR groups (p = 0.016, p = 0.03).
Training under cognitive load benefitted performance on an actual surgical task under similar conditions.

• | Tested whether training in a laparoscopic task under cognitive load can improve the performance on an actual surgical task under similar conditions. |
• | Both VR and VR + CL groups improved their task performance with training with a significant difference in the learning curve between them. |
• | Pre, post and retention tests showed both VR and VR + CL groups performed better than the control group who had no training. |
• | When tested on a transfer task, VR + CL group outperformed on the bimanual dexterity measure when compared to VR and Control groups under CL. |
• | There is a benefit in training under CL condition as shown by the performance on a surgical relevant transfer task. |
