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 ? ”
A comprehensive work injury prevention program with clerical and office workers: phase I.
The risk for the development of musculoskeletal disorders and associated conditions in clerical and office workers is well documented . The majority of work injury prevention programs for this population were single-faceted ( education , workstation re design , or task modification ) and yielded both positive and negative findings . This pilot study was conducted with 16 full-time clerical and office workers at a small private college . In a r and omized control trial , the intervention group received four hours of individualized training through a multi-faceted injury prevention program . Between group differences in musculoskeletal symptom frequency and intensity and perceived stress and energy levels existed , although were statistically insignificant . There was a statistically significant decrease in Lower Back ache/pain from pre to post measures for the intervention group
