INTRODUCTION
This study examined the validity of tensiometry as an objective method of assessing the improvements in the quality of knots and technical performance due to practice on suturing and knot-tying skills.
METHODS
We evaluated the quality of 1,830 knots produced by undergraduate medical students before training (pre-test), after (post-test), and after a week retention (retention-test) using tensiometry. These results were compared to expert-based assessments of products and performance.
RESULTS
Tensiometry, as well as expert-based assessments can detect changes in the quality of knots and technical performance from pre to post and retention-test ( p<0.05). However, these three methods may assess different dimensions of the same products and actions.
CONCLUSIONS
The development of trainee evaluation criteria for the acquisition of surgical skills is a crucial element in surgical education. Based on our patterns of results it is hypothesized that tensiometry can serve as an economic first approximation of the quality of knots and suturing performance.
引言
本研究检验了张力测定法作为一种客观方法评估由于缝合和打结技能练习而导致的结的质量和技术性能改善的有效性。
方法
我们使用张力测定法评估了本科医学生在训练前（预测试）、训练后（后测试）以及一周后（保留测试）所打的1830个结的质量。这些结果与基于专家的产品和性能评估进行了比较。
结果
张力测定法以及基于专家的评估能够检测出从预测试到后测试以及保留测试期间结的质量和技术性能的变化（p<0.05）。然而，这三种方法可能评估的是同一产品和操作的不同维度。
结论
制定外科手术技能获取的学员评估标准是外科教育中的关键要素。基于我们的结果模式，推测张力测定法可作为结的质量和缝合性能的一种经济的初步近似评估方法。
