Surgical Skill Assessment Using Motion Quality and Smoothness

摘要: Objectives This article presents a quantitative technique to assess motion quality and smoothness during the performance of micromanipulation tasks common surgical maneuvers. The objective is investigate effectiveness jerk index, derivative acceleration with respect time, as kinetostatic measure for assessment performance. Design A forceps was instrumented position tracker accelerometer that allowed measurement relative tool motion. Participants were asked perform peg-in-hole on modified O’Connor Dexterity board Tweezer pegboard (placed inside skull). Normalized index calculated each individual task compare group. Setting study conducted at Project neuroArm, Cumming School Medicine, University Calgary. Four groups participants (surgeons, surgery residents, engineers, gamers) participated in tests. Results showed surgeons exhibited better all tasks. Moreover, residents experienced motions closer compared engineers gamers. One-way analysis variance test indicated significant difference between mean values normalized indices among 4 value significantly varied group from one another. Conclusions an independent parameter time amplitude indicator can be used hand dexterity surgeons. Furthermore, method provides quantifiable metrics trainee proficiency, particularly relevant training shifts toward competency-based paradigm.
