I. Introduction
Working posture and limbs movements of a worker during the workday give important data for assessment of the risk of Musculoskeletal Disorders (MSDs) at the workplace. University employees are in general office workers who spend numbers of hours working at computer workstations. During the last two years, as a consequence of the Covid-19 pandemic, the contact with students was realized mainly through technologies requiring the usage of devices such as desktop computers, laptops, tablets and smartphones. This work represents a complex of physical working environment, various dimensions of the human body and over a long period has a negative impact on workers in the shape of chronic musculoskeletal health problems [1] . The risk of musculoskeletal injury is associated with long workhours in a static, incorrect or awkward posture. The correct posture on the other hand maintains a natural curvature of the spine, minimizing tension and preserving musculoskeletal balance in the human’s body. An ergonomic workplace assessment could be a basis for improving of the occupational health [2 , 3 , 12] . An inappropriate setting of the workplace, a noncorrect posture, nonadjustable furniture lead to extended or shortened muscles, which combined with the duration of the activity impacts negatively the employee in the shape of stiffening, not satisfactory concentration, bad quality of the work and last but not least – errors.
