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 ) .
A randomised controlled trial on whether a participatory ergonomics intervention could prevent musculoskeletal disorders
Objectives : To examine the efficacy of a participatory ergonomics intervention in preventing musculoskeletal disorders among kitchen workers .  Participatory ergonomics is commonly recommended to reduce musculoskeletal disorders , but evidence for its effectiveness is sparse . Methods : A cluster r and omised controlled trial among the 504 workers of 119 kitchens in Finl and was conducted during 2002–2005 . Kitchens were r and omised to an intervention ( n = 59 ) and control ( n = 60 ) group . The duration of the intervention that guided the workers to identify strenuous work tasks and to seek solutions for decreasing physical and mental workload , was 11 to 14 months . In total , 402 ergonomic changes were implemented . The main outcome measures were the occurrence of and trouble caused by musculoskeletal pain in seven anatomical sites , local fatigue after work , and sick leave due to musculoskeletal disorders . Individual level data were collected by a question naire at baseline and every 3 months during the intervention and 1-year follow-up period . All response rates exceeded 92 % . Results : No systematic differences in any outcome variable were found between the intervention and control groups during the intervention or during the 1-year follow-up . Conclusions : The intervention did not reduce perceived physical work load and no evidence was found for the efficacy of the intervention in preventing musculoskeletal disorders among kitchen workers . It may be that a more comprehensive re design of work organisation and processes is needed , taking more account of workers ’ physical and mental re sources
