人体工效学中的性别平等：腹腔镜手术中男性和女性的肌肉活动特性是否不同？

背景

女性外科医生在进行手术时可能会遇到更多来自人体工效学的挑战。我们旨在评估男女外科医生之间人体工效学特性的差异。

方法学

所有研究数据来自同一机构内的腹腔镜外科医生。使用Delsys的TrignoTM无线表面肌电设备对所有受试者的斜方肌上群 (UT)、三角肌前群、桡侧腕屈肌 (FCR) 和指伸肌 (ED)的肌电数据在手术中的活动情况进行统计分析。对男性和女性进行手术操作时的大自主收缩 (MVC) 和中值频率 (MDF)等指标进行比较。同时采用Piper 疲劳量表 12 (PFS-12) 以评估自我疲劳程度。使用 SPSS v26.0软件进行统计分析，α= 0.05。

研究结果

共采集了 18 次手术数据（女性：8，男性：10）。结果表明：手术中，女性在斜方肌上群 UT（32% vs 23%，p< 0.001）、桡侧腕屈肌FCR（33% vs 16%，p< 0.001）和指伸肌ED（13% vs 10%，p< 0.001）中的活动度较男性更高，并且指伸肌ED 承担工作量更多（90.4 ± 18.13 vs 99.1 ± 17.82Hz）。

结论

在加权了身高和手术持续时间等因素后，研究结果表明女性腹腔镜外科医生的肌肉激活程度在进行手术操作时有明显的增加。考虑到不良的工效学设计可能是导致职业病的主要原因，因此必须明确男性和女性在人体工效学上的差异，并评估影响这些差异的因素。

Background

Women surgeons may experience more ergonomic challenges while performing surgery. We aimed to assess ergonomics between men and women surgeons.

Methods

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.

Results

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.

Conclusions

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.
