RESUMO
BACKGROUND: Practicing incorrect postures in online and virtual education during the COVID-19 pandemic can cause significant study-related musculoskeletal problems among students. OBJECTIVE: This study evaluated the knowledge, attitude, and practice of sitting posture and computer ergonomics and study-related musculoskeletal problems in undergraduates who followed online education during the pandemic. METHODS: A cross-sectional online survey among a cohort of Sri Lankan medical undergraduates was conducted using a structured questionnaire with 56 multiple-choice or Yes/No type questions. RESULTS: Of the 410 participants, over 85% (nâ=â362) knew the correct posture to sit on the chair type that they frequently used for studies. However, the majority (nâ=â378,92.20%) practised incorrect sitting postures in which leaning forward (nâ=â319,77.80%) was the most common suboptimal posture. Knowledge (nâ=â161,40%) and practice (nâ=â167,40.73%) on taking frequent breaks were poor among the majority. Their knowledge on computer ergonomics was good (>80%, nâ=â304) except for the recommended eye-to-screen distance (nâ=â129,31.46%). Importantly, â¼50% (nâ=â206) did not practise the recommended eye-to-screen distance. Use of non-adjustable chairs with no armrests (nâ=â346,84.39%) and smartphones (nâ=â354,86.34%) were identified as the main factors which hindered correct practices. Study-related pain/discomfort reported by the majority (nâ=â241,58.78%) is potentially due to suboptimal ergonomics. Their attitude toward learning and practicing correct ergonomics in home workstations was good (nâ=â383,93.41%). CONCLUSION: Poor practice of posture and computer ergonomics, despite the good knowledge and attitude is possibly due to the suboptimal work environments. Introducing simple practical measures to facilitate ergonomically appropriate work environments is mandatory in virtual education to prevent study-related musculoskeletal problems.
