目的利用虚拟现实模拟器(LapSim(R))评估视觉空间知觉对新手的腹腔镜操作能力的影响。材料与方法24名新手完成标准化的视觉空间知觉测试(Lameris Toegepaste Natuuretenschappelijk Onderzoek[TNO]Test(R)和Stumpf-Fay Cube Perspections Test(R))，同时在LapSim(R)上进行1h的练习，包括协调、切割和夹子应用任务。结果视觉空间知觉程度与LapSim(R)评分显著相关。空间知觉程度高的受试者(A组)比空间知觉程度低的受试者(B组)完成任务的速度更快(p=0.001)。空间知觉程度高的个体在运动经济性(p=0.021)、组织损伤(p=0.009)和总误差(p=0.007)方面的得分也更高。结论在新手中，视觉空间知觉与在虚拟现实模拟器上执行的手动技能有关。这一结果可能对教育工作者制定适当的、可个别调整的培训计划很重要。
Objects This study evaluates the influence of visual-spatial perception on laparoscopic performance of novices with a virtual reality simulator (LapSim (R)).Materials and methods Twenty-four novices completed standardized tests of visual-spatial perception (Lameris Toegepaste Natuurwetenschappelijk Onderzoek [TNO] Test (R) and Stumpf-Fay Cube Perspectives Test (R)) and laparoscopic skills were assessed objectively, while performing 1-h practice sessions on the LapSim (R), comprising of coordination, cutting, and clip application tasks. Outcome variables included time to complete the tasks, economy of motion as well as total error scores, respectively.Results The degree of visual-spatial perception correlated significantly with laparoscopic performance on the LapSim (R) scores. Participants with a high degree of spatial perception (Group A) performed the tasks faster than those (Group B) who had a low degree of spatial perception (p=0.001). Individuals with a high degree of spatial perception also scored better for economy of motion (p=0.021), tissue damage (p=0.009), and total error (p=0.007).Conclusion Among novices, visual-spatial perception is associated with manual skills performed on a virtual reality simulator. This result may be important for educators to develop adequate training programs that can be individually adapted.
