Moderate evidence was observed for : ( 1 ) no effect of workstation adjustment , ( 2 ) no effect of rest breaks and exercise and ( 3 ) positive effect of alternative pointing devices .
For all other interventions mixed or insufficient evidence of effect was observed .
Conclusion : Few high quality studies were found that examined the effects of interventions in the office on musculoskeletal or visual health
Background : The literature examining the effects of workstation , eyewear and behavioral interventions on  musculoskeletal and visual symptoms among computer users is large and heterogeneous .
Methods : A systematic review of the literature used a best evidence synthesis approach to address the general question “ Do office interventions among computer users have an effect on musculoskeletal or visual health ? ”
Group Training with Healthy Computing Practices to Prevent Repetitive Strain Injury (RSI): A Preliminary Study
This pilot study investigated whether group training , in which participants become role models and coaches , would reduce discomfort as compared to a nontreatment Control Group . Sixteen experimental participants participated in 6 weekly 2-hr group sessions of a Healthy Computing program whereas 12 control participants received no training .  None of the participants reported symptoms to their supervisors nor were they receiving medical treatment for repetitive strain injury prior to the program . The program included training in ergonomic principles , psychophysiological awareness and control , sEMG practice at the workstation , and coaching coworkers . Using two-tailed t tests to analyze the data , the Experimental Group reported ( 1 ) a significant overall reduction in most body symptoms as compared to the Control Group and ( 2 ) a significant increase in positive work-style habits , such as taking breaks at the computer , as compared to the Control Group . This study suggests that employees could possibly improve health and work style patterns based on a holistic training program delivered in a group format followed by individual practice
