There was strong evidence for one intervention category , resistance training , leading to the recommendation : Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms .
The synthesis also revealed moderate evidence for stretching programmes , mouse use feedback and forearm supports in preventing UEMSD or symptoms .
There was also moderate evidence for no benefit for EMG biofeedback , job stress management training , and office workstation adjustment for UEMSD and symptoms .
The burden of disabling musculoskeletal pain and injuries ( musculoskeletal disorders , MSDs ) arising from work-related causes in many workplaces remains substantial .
There is little consensus on the most appropriate interventions for MSDs .
Our objective was to up date a systematic review of workplace-based interventions for preventing and managing  upper extremity MSD ( UEMSD ) .
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
