Description

Poor operative ergonomics can lead to muscle fatigue and injury. However, formal ergonomics education is uncommon in surgical residencies. Our study examines the prevalence of musculoskeletal (MSK) symptoms, baseline ergonomics knowledge, and the impact of an ergonomics workshop in general surgery residents. Musculoskeletal disorders (MSDs), often caused by working in non-ergonomic circumstances, are the most important category of work-related diseases. Different methods exist for examining ergonomics through a variety of postural evaluation techniques (e.g. Rapid Entire Body Assessment (REBA)), which are mostly performed through manual survey-based observations. Consequently, measuring ergonomics of operators is time-consuming and happens only sporadically, often after problems occur. Furthermore, as an ergonomist must assign a score to the performed activity, the ergonomics evaluation is subjective.

These problems can be resolved by continuous and automated ergonomic load monitoring methods that directly provide feedback to operators. In order to monitor the operator without interfering the task at hand, a vision-based ergonomics monitoring system is developed. Here, ergonomic features (e.g. joint angles) are estimated based on multiple video streams, which are used to calculate an objective ergonomic score using a standard ergonomics evaluation technique. Although cognitive operator support systems (i.e. digital work instructions) for manual assembly environments are widely used, they do typically not include ergonomics information. Organizational Design and Management (ODAM) elements of Ergonomics and Human Factors (E/HF) apply to congress organization. Exemplary delegate and organizer E/HF experience is constrained by shifting requirements, time pressures and financial constraints. E/HF application while organizing the International Ergonomics Association's Triennial Congress in 2021 (IEA2021) is described focusing on delivery platforms considering typical and exceptional (pandemic) constraints, emphasizing ODAM E/HF principles and generalizable lessons.
