We examined the effectiveness of technical training (TT) and quiet eye training (QE) on the performance of one-handed square knot tying in surgical residents.
Twenty surgical residents were randomly assigned to the 2 groups and completed pretest, training, retention, and transfer tests. Participants wore a mobile eye tracker that simultaneously recorded their gaze and hand movements. Dependent variables were knot tying performance (%), QE duration (%), number of fixations, total movement time (s), and hand movement phase time (s).
The QE training group had significantly higher performance scores, a longer QE duration, fewer fixations, faster total knot tying times, and faster movement phase times compared with the TT group. The QE group maintained performance in the transfer test, whereas the TT group significantly decreased performance from retention to transfer.
QE training significantly improved learning, retention, and transfer of surgical knot tying compared with a traditional technical approach. Both performance effectiveness (performance outcome) and movement efficiency (hand movement times) were improved using QE modeling, instruction, and feedback.
我们研究了技术培训(TT)和静视训练(QE)对外科住院医师单手打方结操作表现的有效性。
20名外科住院医师被随机分为两组,完成前测、培训、保持和迁移测试。参与者佩戴可移动眼动追踪仪,同时记录他们的注视和手部动作。因变量包括打结表现(%)、静视持续时间(%)、注视次数、总移动时间(秒)和手部移动阶段时间(秒)。
与TT组相比,QE训练组的表现得分显著更高,静视持续时间更长,注视次数更少,总打结时间更快,移动阶段时间更快。QE组在迁移测试中保持了表现,而TT组从保持测试到迁移测试表现显著下降。
与传统技术方法相比,QE训练显著提高了外科打结的学习、保持和迁移能力。使用QE建模、指导和反馈,表现有效性(表现结果)和动作效率(手部移动时间)均得到了提高。
