Increased incidence of musculoskeletal pain in medical students during distance learning necessitated by the COVID-19 pandemic

As a consequence of lockdown during the COVID-19 pandemic, the education system has changed globally. Face to face education has been replaced by distance learning. The aim of the present study was to find the prevalence of musculoskeletal pain and syndromes among medical students during distance learning and to investigate the correlations of musculoskeletal pain with different causal factors. A total of 282 students completed an online questionnaire that measured time spent on digital devices, type of physical activity, time spent sitting, number of walking days/week, ergonomics, and postural habits. Some of these measurements were compared between periods before and during the pandemic. Because of distance learning, time spent on digital devices and total time spent sitting increased significantly from before to during the pandemic (p < 0.001); students' daily physical activities and the number of days per week with at least 10 min of walking decreased significantly (p < 0.001). Most of the students (75.9%) experienced at least one type of musculoskeletal pain, predominately shoulder and neck pain (65%). There was a very significant positive correlation between musculoskeletal pain and postural habits (p < 0.0001). This study suggested that postural habits while sitting have a profoundly negative effect on the musculoskeletal system and are factors in the causation of musculoskeletal pain.
