400+ Validation Studies
Evidence-based Simulation Training
Find here a selection of validation studies, the culmination of extensive research and rigorous validation processes providing evidence of the validity and reliability of our simulation technology, which helped pave the way for revolutionizing surgical education and training. Based on some of the studies we have established proficiency-based curricula which are integrated into our simulators.

Background: Very few studies have addressed the transferability of skills from virtual reality (VR) to real life. The aim of this study was to assess the feasibility and effectiveness of teaching intracorporeal knot tying (ICKT) by VR simulation only.
Methods: Twenty novices underwent structured training of basic skills training on the Minimally Invasive Surgical Trainer simulator (Mentice AB, Gothenburg, Sweden) followed by knot tying training on the LapSim simulator (Surgical Science, Gothenburg, Sweden). They were assessed pre- and post-training on a video trainer. Assessment of performance included motion tracking and video-based checklist. Nonparametric statistical analysis was used, and P < .05 was deemed significant.
Results: All participants completed a correct knot as compared with only 25% before VR training. Time to completion was 66% faster and knot quality 45% better after VR training. Significant reduction in number of movements (P = .006) and distance traveled (P < .000) by both hands after VR training.
Conclusions: Teaching ICKT by VR simulators only is feasible and effective. Furthermore, this study highlights the complementary use of different VR simulators within a structured curriculum.
