Assessing Bimanual Performance in Brain Tumor Resection With NeuroTouch, a Virtual Reality Simulator

摘要: Background Validated procedures to objectively measure neurosurgical bimanual psychomotor skills are unavailable. The NeuroTouch simulator provides metrics determine performance, but validation is essential before implementation of this platform into training, assessment, and curriculum development. Objective To develop, evaluate, validate performance for resection simulated brain tumors with NeuroTouch. Methods Bimanual 8 differing color, stiffness, border complexity was evaluated. Metrics assessed included blood loss, tumor percentage resected, total normal volume removed, tip path lengths, maximum sum forces used by instruments, efficiency index, ultrasonic aspirator length coordination ratio. Six neurosurgeons 12 residents (6 senior 6 junior) were Results Increasing impaired resident significantly more than neurosurgeons. Operating on black vs glioma-colored resulted in higher loss lower percentage, whereas altering tactile cues from hard soft decreased resection. Regardless complexity, significant differences found between neurosurgeons, residents, junior index index. Ultrasonic force ratio outlined demonstrated Conclusion incorporating the scenarios differentiates novice expert demonstrating face, content, construct validity possibility developing proficiency benchmarks.
