ObjectivesComputer workstations are considered a potential workplace hazard. This study sought to evaluate computer workstation ergonomics in a university office environment, and to determine its relationship with musculoskeletal (MS) and visual symptoms reported by employees.Material and MethodsThis was a cross-sectional observational study. A total of 231 university employees were recruited using a stratified random sampling technique. By means of direct observation, computer workstations were evaluated using the Occupational Safety and Health Administration (OSHA) Ergonomic Computer Workstation Evaluation Checklist. In addition, the participants reported MS and visual symptoms during the past week and 12 months by completing questionnaires.ResultsSeveral ergonomic deficiencies in computer workstations were identified. Seating, working area, and keyboard and input devices had the most documented deficits. A significant proportion of employees reported various MS symptoms during the past 12 months. The most affected body parts were the shoulders (37%), the lower back (34%), and the neck (29%). The most prevalent visual symptom was tired eyes (68%). Logistic regression analysis indicated that MS symptoms, such as ache, pain and discomfort, were significantly associated with the total scores on the OSHA components. Deficits in monitor ergonomics and its placement, particularly the presence of glare reflected on the screen, were also associated with reported visual symptoms. Independent variables, such as gender, age, employment duration, job type, daily computer work hours, and work pattern, reliably predicted the participants’ reported experience of various MS and visual symptoms.ConclusionsBoth MS and visual symptoms are associated with deficits in computer workstation ergonomics. Appropriate strategies, work practices, and preventive measures are needed to eliminate occupational hazards associated with computer workstations.

Background The COVID-19 pandemic has led to a fundamental change in the lifestyle and the ways of learning and working patterns which in turn might lead to health consequences including musculoskeletal disorders. The aim of this study was to evaluate the conditions of e-learning and remote working and the impact of the learning/working modality on the occurrence of musculoskeletal symptoms among university students and workers in Poland. Material and Methods This study covered 914 students and 451 employees who filled in an anonymous online questionnaire. The questions covered 2 periods: before the COVID-19 pandemic and during the period from October 2020 to June 2021 and were aimed at obtaining information about lifestyle (including physical activity, perceived stress and sleep pattern), ergonomic of computer workstations, the incidence and severity of musculoskeletal symptoms and headaches. Results During the outbreak, the severity of musculoskeletal complaints increased significantly in the teaching staff group (3.2±2.5 vs. 4.1±3.0 VAS pts), in the administrative staff group (3.1±2.5 vs. 4.0±3.1 VAS pts), and in the student group (2.8±2.4 vs. 3.5±2.8 VAS pts). The average level of burden and risk of musculoskeletal complaints was revealed by the assessment using the ROSA method, in all 3 study groups. Conclusions In light of current results, it is very important to educate people on the rational use of new technology devices, including the appropriate design of computer workstations, planning breaks and time for recovery and physical activity.

Wstęp Epidemia COVID-19 przyczyniła się do zasadniczej zmiany stylu życia oraz sposobu nauki i pracy, co potencjalnie może prowadzić do poważnych konsekwencji zdrowotnych, zwłaszcza w kontekście dolegliwości mięśniowo-szkieletowych. Celem badania była ocena wpływu nauki i pracy zdalnej na niektóre aspekty stylu życia i sposób wykonywania nauki/pracy oraz występowanie dolegliwości mięśniowo-szkieletowych u studentów i pracowników uczelni wyższych w Łodzi. Materiał i metody Badaniem objętych zostało 914 studentów i 451 pracowników, którzy wypełnili anonimowy kwestionariusz online. Pytania dotyczyły 2 okresów: przed epidemią COVID-19 oraz w jej trakcie od października 2020 r. do czerwca 2021 r. i miały na celu uzyskanie informacji o stylu życia (w tym aktywności fizycznej, snu i odczuwanego stresu), ergonomii stanowisk pracy przy komputerze, występowania i nasilenia objawów mięśniowo-szkieletowych oraz bólu głowy. Wyniki W czasie epidemii istotnie wzrosło nasilenie dolegliwości mięśniowo-szkieletowych w grupie pracowników dydaktycznych (3,2±2,5 vs 4,1±3,0 pkt VAS), w grupie pracowników administracyjnych (3,1±2,5 vs 4,0±3,1 pkt VAS) oraz w grupie studentów (2,8±2,4 vs 3,5±2,8 pkt VAS). Na podstawie oceny stanowisk pracy metodą ROSA stwierdzono, że poziom obciążenia i ryzyka wystąpienia dolegliwości mięśniowo-szkieletowych był średni we wszystkich 3 grupach badanych. Wnioski W świetle uzyskanych wyników bardzo ważna jest edukacja w zakresie racjonalnego korzystania z urządzeń nowych technologii, w tym odpowiedniego zaprojektowania komputerowych stanowisk pracy/nauki, planowania przerw i czasu przeznaczonego na regenerację oraz aktywność fizyczną.
