The impact of increased computer screen time during the COVID-19 pandemic on the occurrence of upper part of musculoskeletal diseases among health personnel.

Health personnel who played a key role in the fight against the pandemic stayed during it burdened with increased working time using a computer. We analyzed the impact of increased computer working time during the COVID-19 pandemic on the occurrence of the upper part of musculoskeletal diseases among health personnel. The study group consisted of 418 health personnel, divided according to the time they worked at the computer during the pandemic: up to 2 h a day, from 3 to 5 h a day, and more than 6 h a day. The ICF profile analyzed symptoms of dysfunction of structures of the upper part of the musculoskeletal system (head and cervical spine, shoulder girdle, elbow joint, wrist joint). Employees working more than 6 h daily had a higher risk of developing restrictions in tone of isolated muscles and muscle groups p < 0.001), range of motion of the shoulder girdle (p < 0.001), increased tension of paraspinal muscles (p < 0.001), weakened shoulder girdle muscle strength (p < 0.001), elbow joint pain (p = 0.016), wrist joint pain (p < 0.001), coordination disorders (p = 0.004), difficulties in arm and hand use (p < 0.001), lifting and carrying objects (p = 0.008) and paraesthesia (p < 0.001) compared to those working less than 2 h daily. Additionally, working for 3-5 h and above 6 h compared to health personnel working up to 2 h was associated with a greater risk of headaches and cervical spine pain (p < 0.001), shoulder girdle pain (p < 0.001), limited mobility in the wrist joint (p = 0.003), and tremors (p < 0.001), that working below 2 h. Prolonged computer working time among health personnel during the COVID-19 pandemic is significantly associated with an increased risk of dysfunction and pain in structures of the upper part of the musculoskeletal system. Effective preventive measures are necessary to improve the functioning of the musculoskeletal system during extended periods of computer use.
