Since the NeuroTouch simulator platform is being utilized throughout the word by multiple centres to foster neurosurgical technical skill acquisition, it is critical to study the validity of this system. In this work, we assessed the psychomotor skills of board certified neurosurgeons (experts), senior and junior neurosurgical residents, and medical students while performing a variety of simulated brain tumor resections. Motor skills of operators are measured objectively using a set of novel performance metrics derived from the simulator. The authors provide a statistical analysis of each...
