Women surgeons may experience more ergonomic challenges while performing surgery. We aimed to assess ergonomics between men and women surgeons.
Laparoscopic surgeons from a single institution were enrolled. Demographics and intraoperative data were collected. Muscle groups were evaluated objectively using surface electromyography (EMG; TrignoTM, Delsys, Inc., Natick, MA), and comprised upper trapezius (UT), anterior deltoid, flexor carpi radialis (FCR), and extensor digitorum (ED). Comparisons were made between women (W) and men (M) for each muscle group, assessing maximal voluntary contraction (MVC) and median frequency (MDF). The Piper Fatigue Scale-12 (PFS-12) was used to assess self-perceived fatigue. Statistical analyses were performed using SPSS v26.0, α = 0.05.
18 surgeries were recorded (W:8, M:10). Women had higher activation of UT (32% vs 23%, p < 0.001), FCR (33% vs 16%, p < 0.001), and ED (13% vs 10%, p < 0.001), and increased effort of ED (90.4 ± 18.13 Hz vs 99.1 ± 17.82 Hz). Comparisons were made between W and M for each muscle group, assessing MVC and MDF.
After controlling for surgeon's height and duration of surgery, an increase in muscle activation was seen for women laparoscopic surgeons. Since poor ergonomics could be a major cause of work-related injuries, we must understand differences in ergonomics between men and women and evaluate which factors impact these variations.
女性外科医生在手术过程中可能会遇到更多的人体工程学挑战。我们旨在评估男女外科医生之间的人体工程学差异。
招募了来自一家机构的腹腔镜外科医生。收集了人口统计学和术中数据。使用表面肌电图（EMG；TrignoTM，Delsys，Inc.，Natick，MA）客观评估肌肉群，包括上斜方肌（UT）、三角肌前束、桡侧腕屈肌（FCR）和伸指肌（ED）。比较了女性（W）和男性（M）的每组肌肉，评估最大自主收缩（MVC）和中位频率（MDF）。使用 Piper 疲劳量表-12（PFS-12）评估自我感知疲劳。使用 SPSS v26.0 进行统计分析，α=0.05。
记录了 18 例手术（W：8，M：10）。女性的 UT（32%对 23%，p<0.001）、FCR（33%对 16%，p<0.001）和 ED（13%对 10%，p<0.001）的激活更高，ED 的努力程度更高（90.4±18.13 Hz 对 99.1±17.82 Hz）。比较了 W 和 M 的每组肌肉，评估 MVC 和 MDF。
在控制外科医生身高和手术持续时间后，女性腹腔镜外科医生的肌肉激活增加。由于不良的人体工程学可能是导致与工作相关的伤害的主要原因，我们必须了解男女之间的人体工程学差异，并评估哪些因素会影响这些差异。
