ABSTRACT
Background: During the coronavirus disease (COVID-19) pandemic, people volunteered for sewing hand-made face masks. However, sewing-machine operating might be associated with high ergonomic risk and a negative impact on musculoskeletal health. Objective and Methods: This paper describes an ultrasonographic diagnosis of a foot ganglion - after sewing 300 face masks within two months using a foot-operated sewing machine. Results: The patient significantly improved after an ultrasound-guided aspiration and corticosteroid injection. Conclusion: In short, we highlight the importance of ultrasound examination in the management of work (overuse)- related disorders in occupational medicine practice.
