Objective: To develop a modeling-based human body and a series of training dataset of somatosensory evoked potential(SSEP). Methods: In this study, 30 scoliosis patients underwent correction surgery were recruited to collect intraoperative SSEP signals. Based on those SSEP dataset, various noises and failures simulation were generated by a contaminated interference or signal reduction. Results: We developed a virtual training system to perform an online assessment of intraoperative SSEP monitoring operation. Using this system, the connection of the electrodes will be evaluated, so that the outcomes of SSEP monitoring will be simulated with various kinds of signals. After identifying the different kinds of output, the trainee can be trained by own practice, while the monitoring skill can be evaluated by the system. Conclusion: This virtual training system can be used as a training tool in medical school, as well as clinical training centre, which improve the skill of electrophysiological test and intraoperative SSEP monitoring.
