Relationships Between Working From Home, Sitting Postures, and Low Back Pain During COVID-19: A Survey of Frequent Computer Users.

Objective: The aim of the study is to investigate the effects of working from home on musculoskeletal pain.

Methods: An e-survey of computer workers was conducted. Multinomial logistic regression modeling examined relationships between work location (work or home office desk, dining table, other), sitting posture (diagrams with descriptors), depressive symptoms (Center for Epidemiologic Studies Short Depression Scale), sleep quality (good/average vs poor) and pain (low back pain [LBP]), and other pain without LBP (asymptomatic).
