ABSTRACT
In the article, the authors present the part of findings of research on changes in loads brought to bear on the musculoskeletal system during the operation of various cameras models. The study programme includes measurements of the positions of musculoskeletal system segments during the operation of cameras (taken with electronic goniometers and torsiometers) as well as static and dynamic posturographic measurements taken to identify shifts in camera operator foot pressure against the ground and ascertain the centre of gravity of camera operator bodies. To maintain balance, the operators compensate the asymmetrical positioning of cameras (on their right shoulders) by, inter alia, laterally bending their trunks. Other postural adjustments include changes in the pressure exerted by the feet. The asymmetry of both the loads and camera operator postures may become habitual, increasing the risk of musculoskeletal system degeneration (Gnat et al. 2006).
