Abstract The objective of this study was to evaluate the impact of two types of office layouts on workers' upper limb muscle solicitation and posture, and to document the effects of the layouts on comfort and perceived pain. One workstation was organized according to the ergonomic criteria of the Canadian Standards Association. Another, with a single surface, promoted direct forearm support on the work surface. The activity of the trapezius, anterior deltoid and finger extensor muscles, as well as head, trunk, and dominant arm and wrist postures were measured to determine the impacts of the two layouts. Tasks, psychosocial aspects, comfort and perceived pain, as well as the functional limitation associated with this pain, were documented. Measurements of the different workstation components were used to determine the extent of the modifications carried out for each of these two layouts. Findings are discussed.
