To investigate the self-perception of vocal fatigue symptoms and musculoskeletal pain in home office workers before and during the coronavirus disease (COVID-19) pandemic.
A total of 424 individuals participated in this cross-sectional, observational, and descriptive study; they were stratified into the experimental group (EG), consisting of 235 individuals working from home office during the COVID-19 pandemic; and the control group (CG), with 189 individuals who continued to work in person during this period. All participants answered the vocal fatigue index and the musculoskeletal pain investigation questionnaires. The data were analyzed in a descriptive and inferential manner.
Participants in the EG reported more vocal fatigue symptoms and musculoskeletal pain than those in the CG before the pandemic. However, during the pandemic, the EG presented a higher frequency of pain in the posterior of the neck, shoulder, upper back, and temporal and masseter muscles, while the CG presented a higher frequency of pain in the larynx. With regard to vocal fatigue, during the pandemic, EG had an increase in scores to factors such as tiredness and voice impairment, avoidance of voice use, and total scores. No such differences were noted in the CG.
Workers who migrated to home offices during the COVID-19 pandemic are at risk of developing vocal disorders.
调查冠状病毒病（COVID-19）大流行前后在家办公人员对声音疲劳症状和肌肉骨骼疼痛的自我感知。
共有 424 人参与了这项横断面、观察性和描述性研究；他们分为实验组（EG），由 235 名在 COVID-19 大流行期间在家办公的人员组成；和对照组（CG），有 189 人在这段时间继续亲自工作。所有参与者都回答了声音疲劳指数和肌肉骨骼疼痛调查问卷。数据以描述性和推断性方式进行分析。
与大流行前相比，EG 组参与者报告的声音疲劳症状和肌肉骨骼疼痛比 CG 组多。然而，在大流行期间，EG 组后颈部、肩部、上背部和颞肌和咀嚼肌疼痛的频率较高，而 CG 组喉部疼痛的频率较高。关于声音疲劳，在大流行期间，EG 在疲劳和声音障碍、避免使用声音以及总评分等因素的评分增加。CG 组没有注意到这种差异。
在 COVID-19 大流行期间迁移到家庭办公室的工作人员有发生声音障碍的风险。
