Shoulder muscle tension induced by two VDU-based tasks of different complexity / M. Waersted, R.A. Bjorklund and R.H. Westgaard

Sumario: This paper evaluates task complexity as a task-related factor causing the development of psychologically mediated ("psychogenic") shoulder muscle tension. Eighteen subjects performed an experimental work session, responding to simple and complex reaction time tasks which were presented on a VDU (Visual display unit) screen
