Effects of transcranial direct-current stimulation on laparoscopic surgical skill acquisition

Abstract: BackgroundChanges in medical education may limit opportunities for trainees to gain proficiency in surgical skills. Transcranial direct‐current stimulation (tDCS) can augment motor skill learning and may enhance surgical procedural skill acquisition. The aim of this study was to determine the effects of tDCS on simulation‐based laparoscopic surgical skill acquisition.MethodsIn this double‐blind, sham‐controlled randomized trial, participants were randomized to receive 20 min of anodal tDCS or sham stimulation … Show more

“…Simulation-based task training had the advantage of being low risk and effective in helping trainees attain surgical skills [8]. However, there are still several disadvantages in acquiring complex surgical motor skills through a simple simulation-based task training program, including rapid skill decay, and the program is time-consuming and only modestly effective [9][10][11]. Therefore, it is important to identify an alternative to enhance the efficacy of simulation-based task training.…”

“…We found no effect of stimulation, online or offline, and thus were unable to replicate the results of the study by Cox et al (M. L. Cox et al, 2020). This could be because we only gave stimulation in a single training session compared to other studies, which provided stimulation across multiple training sessions and possibly minimized learning over time (P. Ciechanski et al, 2018; Patrick Ciechanski et al, 2019; M. L. Cox et al, 2020). We also found no interaction effect of stimulation-type and sessions, which means that there was no post-stimulation difference in scores between active and sham stimulations.…”

“…Despite no significant improvement in the peg-transfer task, an appropriately powered study could detect a medium effect size. Moreover, the commonly used peg-transfer task is bimanual; thus, it is expected that the application of anodal tDCS on the dominant side alone may not improve the performance of a bimanual task (P. Ciechanski et al, 2018; Vancleef et al, 2016). Similar results for the effects of tDCS on bimanual performance improvement of peg-transfer task were found by two recent studies (Patrick Ciechanski et al, 2019; M. L. Cox et al, 2020).…”

“…Second, the motor tasks studied in the multimodality studies have largely been basic motor skill tasks, such as simple finger movement or tapping tasks. Complex motor functions have been shown to be enhanced by tES, for example, bimanual coordination tasks ( Pixa and Pollok, 2018 ) or fine motor tasks such as laparoscopic surgical performance ( Ciechanski et al, 2017 , 2018 ). However, neuroimaging was not coupled with those complex tasks to understand how they are affected by tES.…”
