The use of computers as a work tool has had severe and uncomfortable consequences for workers' health. As a result of this demand, occupational physiotherapy has been increasingly required by organizations. However, there is a limited amount of scientific research into physiotherapeutic interventions that allow physiotherapists to guide their work based on scientific evidence.

To describe a study protocol to evaluate the effectiveness of physiotherapeutic intervention on the functionality of workers using computer terminals.

A randomized controlled clinical trial will be carried out with 209 workers over the age of 18 who work in an institution using computers for between 4 and 8 hours a day. The physiotherapy intervention will consist of occupational physiotherapy, which will be carried out daily (Monday to Friday), lasting 15 minutes, at pre-scheduled times, in the workplace itself. Posture school will also be carried out by means of a powerpoint presentation for each participant at their workstation, in which, initially, an explanation will be given about the structures of the body, functionality and posture so that the worker can single-handedly protect their health, reduce discomfort and the risk of injury and increase productivity. Next, possible ergonomic corrections will be made to the workstation, such as adjusting the height of the video monitor and chair, organizing the work table and equipment. Each school will last 30 minutes. There will also be two lectures: the first on ergonomics and the second on self-care. These lectures will be held in an auditorium on a pre-scheduled day and time, and each will last one hour.

It is hoped that after this study, following the biopsychosocial model and the ICF, which interrelate aspects linked to functionality (body structure and function, activity and participation) with contextual factors (personal and environmental), the effects of physiotherapeutic intervention will be observed. Data will be collected according to 5 domains, in which the following instruments have been chosen for each category: Domain 1: body functions and structures (Nordic Musculoskeletal Questionnaire (MNQ)); Domain 2: activities (Work Limitations Questionnaire (WLQ)); Domain 3: participation (Short Form Health Survey (SF-36)); Domain 4: context factors (personal and environmental) (Sociodemographic Questionnaire; International Physical Activity Questionnaire - SHORT VERSION - IPAQ and Couto Checklist for assessing ergonomic conditions in workstations and computerized environments (2014 version)) and Domain 5: World Health Organization Disability Assessment Schedule (WHODAS 2.0). Implications: The existence of a physiotherapeutic intervention protocol allows for the development of scientific knowledge that will provide physiotherapists with efficient choices of conduct, generating opportunities for better action for this population. In addition to promoting the value of physiotherapists in the job market.
