Long-term video game play and its effects on the skills used in surgical simulators have been previously studied, but little information is available about short-term video game warm-ups and subsequent ophthalmic surgical simulation performance. In this study, we hypothesize that a video game warm-up will improve performance on the Eyesi Ophthalmic Surgical Simulator.
Twenty medical students with no prior surgical simulation experience were recruited for the study. Information regarding prior video game experience was gathered, and half of the participants were then randomly assigned to play a video game session prior to Eyesi performance. All subjects completed three sets of Eyesi modules, and the scores and time to completion were recorded. Bivariate analysis including Fisher's Exact test and Wilcoxon rank-sum test were used for statistical analysis.
The warm-up group scored higher in Navigation, Bimanual, and Forceps modules (33.6, 39.7, 7.2, respectively) compared to non-warm-up group (27.3, 27.3, 3.6, respectively). In addition, average times (sec) were lower (310.5, 117.4, 229.2, respectively) compared to non-warm-up group (321.9, 163.3, 235.8, respectively). It was also observed that significantly more participants in the warm-up group had reported a history of spending >15 hours per week playing video games compared to the non-warm-up group (80% vs 20%, p=0.0402).
In our pilot study, there appears to be a positive trend between video game warm-up and Eyesi simulation performance; however, no statistically significant difference was observed due to lower power. This trend can be explained by a greater collective video game experience within the warm-up group, mechanical factors (increased flexibility and grip strength after playing video games) and feeling more relaxed after the video game warm-up. Larger follow-up studies are needed to further investigate the relationship between short-term video game use on ophthalmic surgical simulation performance.
此前已有关于长期玩电子游戏及其对外科手术模拟器中所使用技能的影响的研究，但关于短期电子游戏热身以及随后的眼科手术模拟表现的信息却很少。在本研究中，我们假设进行电子游戏热身将提高在Eyesi眼科手术模拟器上的表现。
招募了20名此前没有外科手术模拟经验的医学生参与该研究。收集了有关先前电子游戏经验的信息，然后将一半参与者随机分配在进行Eyesi操作之前玩一场电子游戏。所有受试者完成三组Eyesi模块，并记录得分和完成时间。使用包括Fisher精确检验和Wilcoxon秩和检验在内的双变量分析进行统计分析。
与未进行热身的组（分别为27.3、27.3、3.6）相比，进行热身的组在导航、双手操作和镊子模块中的得分更高（分别为33.6、39.7、7.2）。此外，与未进行热身的组（分别为321.9、163.3、235.8）相比，平均时间（秒）更低（分别为310.5、117.4、229.2）。还观察到，与未进行热身的组相比，进行热身的组中有更多参与者报告有每周玩电子游戏超过15小时的历史（80%对20%，p = 0.0402）。
在我们的初步研究中，电子游戏热身与Eyesi模拟表现之间似乎存在积极趋势；然而，由于效能较低，未观察到统计学上的显著差异。这种趋势可以通过热身组中更丰富的集体电子游戏经验、机械因素（玩电子游戏后灵活性和握力增加）以及电子游戏热身之后感觉更放松来解释。需要进行更大规模的后续研究，以进一步调查短期使用电子游戏与眼科手术模拟表现之间的关系。
