Computer and Furniture Affecting Musculoskeletal Problems and Work Performance in Work From Home During COVID-19 Pandemic.

Objectives: We surveyed how home-working conditions, specifically furniture and computer use, affected self-reported musculoskeletal problems and work performance.

Methods: Questionnaires from 4112 homeworkers were analyzed. The relationship between subjective musculoskeletal problems or work performance and working conditions were determined by logistic regression analyses.

Results: More than half the homeworkers used a work desk, work chair, and laptop computer. However, approximately 20% of homeworkers used a low table, floor chair/floor cushion, or other furniture that was different from the office setup. Using a table of disproportionate size and height, sofa, floor cushion, and floor chair were associated with neck/shoulder pain or low back pain. Disproportionate table and chair, floor cushion, and tablet computer were associated with poor work performance.

Conclusions: Disproportionate desk and chair, floor cushion/chair, and computer with small screen may affect musculoskeletal problems and home-working performance.
