Simulation is becoming more important in the teaching and assessment of technical skills. The purpose of this study was to refine the use of motion analysis parameters (MAPs) to assess performance of a defined task in low-cost pediatric laparoscopic simulators of differing size.
105 participants performed a defined intracorporeal suturing task in large and small pediatric laparoscopic simulators. Outcomes included MAPs - path length, extreme velocity events, and extreme acceleration events in all available degrees of freedom for novices, intermediates, and experts. ANOVA p <0.05 was judged significant.
In the smaller simulator, all MAPs discriminated between expertise groups in all degrees of freedom. In the larger simulator, all but one MAP discriminated between expertise groups. Experts demonstrated the greatest variability in performance between the larger and smaller simulators.
Analysis of motion in the performance of a defined intracorporeal suturing task allowed discrimination between novices, intermediates, and experts in large and small low-cost pediatric laparoscopic simulators. Further refinement in MAPs will determine their role in surgical education.
Not applicable.
模拟在技术技能的教学与评估中变得愈发重要。本研究的目的是优化运动分析参数(MAPs)的使用,以评估在不同尺寸的低成本小儿腹腔镜模拟器中完成特定任务的表现。
105名参与者在大型和小型小儿腹腔镜模拟器中执行一项特定的体内缝合任务。结果包括MAPs——新手、中级水平者和专家在所有可用自由度下的路径长度、极速事件和极加速度事件。方差分析p<0.05被判定为具有显著性。
在较小的模拟器中,所有MAPs在所有自由度上都能区分不同专业水平的组。在较大的模拟器中,除一个MAP外,其他所有MAPs都能区分不同专业水平的组。专家在较大和较小模拟器之间的表现差异最大。
对特定体内缝合任务表现中的运动进行分析,可以在大型和小型低成本小儿腹腔镜模拟器中区分新手、中级水平者和专家。MAPs的进一步优化将确定它们在外科教育中的作用。
不适用。
