Simulation technologies have advanced surgical education by enhancing motor skills, hand-eye coordination, and sensory acuity. This study examines correlations between sensory-motor skills and surgical simulator performance.
The cross-sectional and observational study included fifty medical doctors without surgical experience. Assessments included the McKinnon two-point discrimination test, the Semmes-Weinstein monofilament test, and the Nine-Hole Peg test. Performance scores for forceps, anti-tremor, and bimanual training modules were recorded using the Eyesi Surgical Simulator (VRmagic, Mannheim, Germany).
The mean age was 28.6 ± 4.4 years, with 28 females and 22 males. The mean value of McKinnon's two-point static discrimination test was 3.08 ± 0.72 mm, the Semmes-Weinstein Monofilament test was 2.42 ± 0.29 inches, and the Nine-Hole Peg Test mean completion time was 19.04 ± 2.60 seconds. Two-point discrimination test showed a significant negative correlation with bimanual training module scores within the 95% confidence interval (r =-0.41, p = 0.0027) but weak, non-significant correlations with forceps module (r = -0.23, p = 0.101) and anti-tremor modules (r = -0.10; p = 0.505). Monofilament test scores showed no significant correlations with simulator modules. The Nine-Hole Peg test correlated significantly with bimanual performance (r =-0.42, p = 0.002 and weakly with forceps scores (r =-0.24, p = 0.090).
Simulation devices enhance surgical training by identifying sensory-motor deficits and adapting training. Motor skill and sensory acuity are associated with better bimanual performance and emphasize individualized approaches for optimal outcomes.
模拟技术通过提高运动技能、手眼协调能力和感觉敏锐度，推动了外科手术教育的发展。本研究旨在探讨感觉运动技能与手术模拟器性能之间的相关性。
这项横断面观察性研究纳入了50名无手术经验的医生。评估项目包括麦金农两点辨别试验、Semmes-Weinstein单丝试验和九孔插钉试验。使用Eyesi手术模拟器（VRmagic，德国曼海姆）记录镊子、抗震颤和双手训练模块的性能得分。
平均年龄为28.6±4.4岁，其中女性28名，男性22名。麦金农两点静态辨别试验的平均值为3.08±0.72毫米，Semmes-Weinstein单丝试验为2.42±0.29英寸，九孔插钉试验的平均完成时间为19.04±2.60秒。两点辨别试验在95%置信区间内与双手训练模块得分呈显著负相关（r=-0.41，p=0.0027），但与镊子模块（r=-0.23，p=0.101）和抗震颤模块（r=-0.10；p=0.505）的相关性较弱且不显著。单丝试验得分与模拟器模块无显著相关性。九孔插钉试验与双手操作性能显著相关（r=-0.42，p=0.002），与镊子得分的相关性较弱（r=-0.24，p=0.090）。
模拟设备通过识别感觉运动缺陷并调整训练，增强了外科手术训练。运动技能和感觉敏锐度与更好的双手操作性能相关，并强调采用个性化方法以实现最佳效果。
