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 .
Effects of ergonomic intervention in work with video display units.
OBJECTIVES This study evaluated the effect of an intensive ergonomic approach and education on workstation changes and  musculoskeletal disorders among workers who used a video display unit ( VDU ) . METHODS A r and omized controlled design was used . The subjects ( N=124 ) were allocated into three groups ( intensive ergonomics , ergonomic education , reference ) using stratified r and om sampling . The evaluation involved question naires , a diary of discomfort , measurements of workload , and an ergonomic rating of the workstations . The assessment s were made 2 weeks before the intervention and after 2 and 10 months of follow-up . RESULTS The intensive and training groups showed less musculoskeletal discomfort than the reference group after 2 months of follow-up . Positive effects on discomfort were seen primarily for the shoulder , neck , and upper back areas . No significant differences were found for the strain levels or prevalence of pain . After the intervention the ergonomic level was distinctly higher in the intensive ergonomic group than in the education or reference group . CONCLUSIONS Both the intensive ergonomics approach and education in ergonomics help reduce discomfort in VDU work . In attempts to improve the physical ergonomics of VDU workstations , the best result will be achieved with cooperative planning in which both workers and practitioners are actively involved
