In 30 seconds
This randomized controlled trial investigated the effect of transcranial direct current stimulation (tDCS) on laparoscopic skill acquisition in 33 medical students. Active tDCS significantly improved final bimanual coordination performance compared to sham stimulation (F (1,13) = 14.92, p = 0.002), while no effects were observed for camera navigation or hand-eye coordination.
Key findings
- Active tDCS improved final bimanual coordination performance compared to sham stimulation (F (1,13) = 14.92, p = 0.002).
- Both groups showed significant improvement in laparoscopic tasks over time (all p < 0.001).
- Baseline visuospatial ability was an independent predictor of performance in camera navigation and hand-eye coordination (both p < 0.01).
Why it matters
The study highlights the potential of neuromodulation techniques like tDCS to enhance specific psychomotor skills in surgical training, which could lead to more effective training programs and improved surgical outcomes.
