The office work and specifically the workwith computer are develop in long periods ofstatic work, which is associated with the developmentof muscle skeletal disorders. In consequence,the authors made a transverse studywith office workers (n=377) of a companydedicated to service activities (managementof information and attention to costumers)in order to explore the relationship betweenthe work structure, the nature of the tasks and thepresence of muscle skeletal disorders, and toidentify a strategy to stimulate the posturaltransition.The information was collected in a questionpaper that went into variables related to the typeof task that the worker develops, the time that hededicates to office and computer activities, disabilities,medical precedents and current symptomatology.The main medical precedents founded inthe evaluated population was: arterial hypertension(HTA), 8%; lipidomics, 23%; diabetes, 3%,and hypoglycemia, 4%. In the evaluated populationwas found that 80% suffer pain, specificallyrelative to upper limbs: hands, 26%; elbows, 3%,and shoulders 4%. In cervical column, 32%; lumbarcolumn, 16%; and dorsal column, 6%. Finally,it was proved that 80% of the worker’s time isdedicated to static work, specifically to typinginformation.The results of this study are applied to thedevelopment of principles to design tasks andto develop a strategy to promote the posturetransitions at work.
