Work-related musculoskeletal disorders are highly disabling. Therefore, finding preventive solutions is fundamental, in order to reduce the damages to workers and society. Therefore the objective of this study will be to evaluate the effect of passive and active pauses in the control of musculoskeletal complaints of office workers. This is a randomized controlled trial by cluster, which will be performed with 286 office workers (administrative sectors). Employees with physical disabilities will not be included in the study. The workers will be distributed into three groups: active control group, and the two intervention groups massage and workout gymnastics. The active control group and the other groups will be guidelines on ergonomic adjustments of the work station, and performing a 10-minute break every 50 minutes work. The intervention groups (passive and active) will receive different interventions: group massage in the chair and group gymnastics labor. The massage will be performed 2x per week for 10 minutes, and workout 2x per week for 15-20minutes. The primary outcomes assessed will be musculoskeletal complaints of pain intensity. And as a secondary outcome will be the ability to work, perception of ergonomic risk factors, psychosocial factors and fatigue, level of physical activity. Outcomes will be assessed at baseline and after 4 months. It is expected that exercise intervention (active pause) is more effective than passive pause (massage), and that pause and guidance can reduce musculoskeletal complaints, pain intensity, and other outcomes evaluated.

Primary | Change from Musculoskeletal complains at 4,8,12,16 weeks | The occurrence of musculoskeletal symptoms (pain, tingling or numbness) will be evaluated through the Nordic Questionnaire for Musculoskeletal Symptoms (QNSO). The interviewee will answer simple questions (yes or no) regarding the musculoskeletal symptoms he has experienced in the last 12 months and / or the last 7 days, the occurrence of functional incapacity and the demand for help from a health professional in the last 12 months resulting from these symptoms. | At baseline, and after 4, 8, 12, and 16 weeks | |
Primary | Change from Pain Intensity at 4, 8, 12, 16 weeks | The intensity of the pain will be evaluated by the Verbal Numerical Scale of Pain. It is an 11-point scale, in which 0 means "no pain" and 10 means "worst possible pain". | At baseline and after 4, 8, 12, and 16 weeks | |
Secondary | Change from Work Ability Index (WAI) at 16 weeks | The Work Ability Index (WAI) is an instrument that evaluates the worker's perception of how well he or she is or will be at the moment or in the near future and how well he can perform his or her job, depending on the requirements, of their state of health and physical and mental capacities. | At baseline and after 16 weeks |
