Purpose : The aim of this study was to objectively compare medical augmented reality glasses (ARG) and conventional monitors in video-assisted surgery and to systematically analyze its ergonomic benefits
Methods : Three surgeons (thoracic, laparoscopic, and thyroid surgeons) participated in the study. Six thoracoscopic metastasectomies, six subtotal laparoscopic gastrectomies, and six thyroidectomies were performed with and without ARG. The subjective experience was evaluated using a questionnaire-based NASA-Task Load Index (NASA-TLX). Postures during surgeries were recorded. The risk of musculoskeletal disorders associated with video-assisted surgery was assessed using Rapid Entire Body Assessment (REBA). Surface electromyography (EMG) was recorded and muscle fatigue was objectively measured.
Results : NASA-TLX scores of three surgeons were lower when ARG was used compared to those with conventional monitor (66.44 vs. 82.67). Less workload during surgery was reported with ARG. The laparoscopic surgeon and thyroid surgeon exhibited a substantial decrease in physical demand (78.1 and -100%). Total REBA scores decreased with ARG (8 to 3.6). The risk of musculoskeletal disorders was improved in regions of the neck and shoulders. Root mean square (RMS) of the EMG signal decreased from 0.347 ± 0.150 to 0.286 ± 0.130 (p < 0.05) with usage of ARG; a decrease was observed in all surgeons. The most RMS decrease was observed in the trapezius and sternocleidomastoid muscles. The decrease in brachioradialis muscle was not significant.
Conclusion : ARG may play a role in the correction of a surgeon’s bad posture during video-assisted surgery and it may be beneficial to reduce muscular fatigue of the upper body.
