Introduction of sit-stand tables is a current trend among office workers spending prolonged time sitting in constrained postures. While sit-stand tables have shown promising effects on sedentariness and cardiometabolic parameters, evidence is limited as to their effect on trunk and upper body posturesThe present study compared postures and posture variation of the head, neck, trunk and upper arms among 24 academics office workers while sitting and standing at a sit-stand table after two months of table usage in real work settings. Postures were recorded for two hours on each of three consecutive days. On basis of observations, work tasks were categorized into computer work while standing (CW-stand), computer work while sitting (CW-sit), non-computer work while standing (NCW-stand) and non-computer work while sitting (NCW-sit). During CW and NCW standing, the head and neck were more flexed, the trunk less flexed, and both arms less elevated than when these tasks were performed sitting. Posture variation was consistently larger during sitting CW and NCW than during standing. Neutral postures occurred more during standing. Thus, shifting between sitting and standing will lead to increased posture variation for the trunk and upper body, which may be an additional benefit of introducing sit-stand tables to office workers with extensive desk work.
