We found inconsistent evidence that the use of an arm support or an alternative mouse may or may not reduce the incidence of neck or shoulder MSDs .
For other physical ergonomic interventions there is no evidence of an effect .
For organisational interventions , in the form of supplementary breaks , there is very low- quality evidence of an effect on upper limb discomfort .
For training and multifaceted interventions there is no evidence of an effect on upper limb pain or discomfort .
BACKGROUND Work-related upper limb and neck musculoskeletal disorders ( MSDs ) are one of the most common occupational disorders worldwide .
Studies have shown that the percentage of office workers that suffer from MSDs ranges from 20 to 60 per cent .
The direct and indirect costs of work-related upper limb MSDs have been reported to be high in Europe , Australia , and the United States .
Although ergonomic interventions are likely to reduce the risk of office workers developing work-related upper limb and neck MSDs , the evidence is unclear .
This is an up date of a Cochrane Review which was last published in 2012 .
OBJECTIVES To assess the effects of physical , cognitive and organisational ergonomic interventions , or combinations of those interventions for the prevention of work-related upper limb and neck MSDs among office workers .
A field intervention examining the impact of an office ergonomics training and a highly adjustable chair on visual symptoms in a public sector organization.
OBJECTIVE Examine the effect of a multi-component office ergonomics intervention on visual symptom reductions . METHODS Office workers were assigned to either a group receiving a  highly adjustable chair with office ergonomics training ( CWT ) , a training-only group ( TO ) or a control group ( C ) . A work environment and health question naire was administered 2 and 1 month(s ) pre-intervention and 3 , 6 , and 12 months post-intervention . Multi-level statistical models tested hypotheses . RESULTS The CWT intervention lowered daily visual symptoms ( p < 0.01 ) post-intervention . The TO group did not significantly differ from the control group . The CWT group differed significantly from the TO group ( p = 0.01 ) post-intervention . CONCLUSION Workers who received a highly adjustable chair and office ergonomics training  had reduced visual symptoms and the effect was maintained through twelve months post-intervention . The lack of a training-only group effect supports implementing training in conjunction with the highly adjustable chair to reduce visual symptoms
