Characterization of Surgical Movements Reveals Differences in Efficiency Between Experienced and Novice Surgeons

The study analyzed surgeons’ hand movements to characterize the differences in movement efficiency between experienced and novice surgeons. Hand motions were recorded using an inertial measurement unit (IMU) during a simulated surgical procedure. The results showed that experienced surgeons exhibited more fluid and efficient hand movements compared to novice surgeons. The angle of roll motion, specifically during suturing, differed significantly between the experience groups. The findings suggest that IMU devices can be used to objectively assess and improve surgical skills.
