Assessment of learning in simulator‐based arthroscopy training with the diagnostic arthroscopy skill score (DASS) and neurophysiological measures

Abstract

AbstractPurposeVirtual arthroscopic training has become increasingly popular. However, there is a lack of efficiency‐based tracking of the trainee, which may be critical for determining the specifics of training programs and adapting them for the needs of each trainee. This study aims to evaluate and compare the measures obtained with a non‐invasive neurophysiological method with The Diagnostic Arthroscopy Skill Score (DASS), a commonly used assessment tool for evaluating arthroscopic skills.MethodsThe study collected simulator performance scores, consisting of “Triangulation Right Hand”, “Triangulation Left Hand”, “Catch the Stars” and “Three Rings” and DASS scores from 22 participants (11 novices, 11 experts). These scores were obtained while participants underwent a structured program of exercises for the fundamentals of arthroscopic surgery training (FAST) and knee module using a simulator‐based arthroscopy device. During the evaluation, data on oxy‐hemoglobin and deoxy‐hemoglobin levels in the prefrontal cortex were collected using the Functional Near‐Infrared Spectroscopy (fNIRS) imaging system. Performance scores, DASS scores, and fNIRS data were subsequently analyzed to determine any correlation between performance and cortex activity.ResultsThe simulator performance scores and the DASSPart2 scores were significantly higher in the expert group compared to the novice group (200.1 ± 28.5 vs 172.5 ± 48.9, p = 0.04 and 9.4 ± 5.6 vs. 5.4 ± 5.6 p = 0.02). In the expert group, fNIRS data showed a significantly lower prefrontal cortex activation during fundamental tasks in the FAST module, indicating significantly more efficient mental resource use.ConclusionThe analysis of cognitive workload changes during simulation‐based arthroscopy training revealed a significant correlation between the trainees’ DASS scores and fNIRS data. This correlation suggests the potential use of fNIRS data and DASS scores as additional metrics to create adaptive training protocols for each participant. By incorporating these metrics, the training process can be optimized, leading to more efficient arthroscopic training and better preparedness for clinical operations.Level of evidenceIII.
