Abstract

BACKGROUND

This study aimed to assess the transferability of basic laparoscopic skills between a virtual reality simulator (MIST-VR) and a video trainer box (D-Box).

METHODS

Forty-six medical students were randomized into 2 groups, training on MIST-VR or D-Box. After training with one modality, a crossover assessment on the other was performed.

RESULTS

When tested on MIST-VR, the MIST-VR group showed significantly shorter time (90.3 seconds vs 188.6 seconds, P <.001), better economy of movements (4.40 vs 7.50, P <.001), and lower score (224.7 vs 527.0, P <.001). However, when assessed on the D-Box, there was no difference between the groups for time (402.0 seconds vs 325.6 seconds, P = .152), total hand movements (THC) (289 vs 262, P = .792), or total path length (TPL) (34.9 m vs 34.6 m, P = .388).

CONCLUSION

Both simulators provide significant improvement in performance. Our results indicate that skills learned on the MIST-VR are transferable to the D-Box, but the opposite cannot be demonstrated.

摘要

背景

本研究旨在评估虚拟现实模拟器（MIST-VR）和视频训练箱（D-Box）之间基本腹腔镜技能的可转移性。

方法

46名医学生被随机分为两组，分别在MIST-VR或D-Box上进行训练。在使用一种方式训练后，对另一种方式进行交叉评估。

结果

在MIST-VR上测试时，MIST-VR组的时间显著更短（90.3秒对188.6秒，P<.001），动作经济性更好（4.40对7.50，P<.001），得分更低（224.7对527.0，P<.001）。然而，在D-Box上评估时，两组在时间（402.0秒对325.6秒，P=.152）、总手部动作（THC）（289对262，P=.792）或总路径长度（TPL）（34.9米对34.6米，P=.388）方面没有差异。
