Effect of transcranial direct current stimulation on psychomotor skill acquisition during laparoscopic training: a randomized controlled trial
To investigate the effect of anodal–cathodal tDCS on the acquisition of basic psychomotor skills during laparoscopic training.
Approach:
Study Design: A prospective, randomized controlled trial (RCT) with a parallel-group design conducted at the Lower Silesian Oncology, Pulmonology, and Hematology Center in Wrocław, Poland.
Participants: Thirty-three medical students without prior laparoscopic experience were recruited and randomly assigned to either the experimental group (tDCS) or control group (sham stimulation).
Intervention: tDCS was applied over bilateral motor cortices during training, using a Halo Sport neuromodulation headset.
Assessment: Laparoscopic psychomotor skills were assessed using the Laparoscopic Skills Testing and Training (LASTT) model.
Key Findings:
tDCS may enhance the acquisition of laparoscopic psychomotor skills.
Baseline psychomotor abilities were evaluated using standardized Vienna Test System (VTS) tasks.
Interpretation:
Limitations:
Small sample size of 33 participants.
Short duration of stimulation and training.
Conclusion:
The study explores the potential of tDCS in enhancing laparoscopic skill acquisition among medical students.
Single-nucleus sequencing of menstrual fluid identified epithelial gene signatures and prioritized five candidate biomarkers that warrant validation in larger studies.
