There was low- to very low- quality evidence that other interventions were not effective in reducing work-related upper limb and neck MSDs in adults .
We found moderate- quality evidence to suggest that the use of arm support with alternative mouse may reduce the incidence of neck/shoulder MSDs , but not right upper limb MSDs .
Moreover , we found moderate- quality evidence to suggest that the incidence of neck/shoulder and right upper limb MSDs is not reduced when comparing alternative and conventional mouse with and without arm support .
However , given there were multiple comparisons made involving a number of interventions and outcomes , high- quality evidence is needed to determine the effectiveness of these interventions clearly .
While we found very-low- to low- quality evidence to suggest that other ergonomic interventions do not prevent work-related MSDs of the upper limb and neck , this was limited by the paucity and heterogeneity of available studies .
BACKGROUND Work-related upper limb and neck musculoskeletal disorders ( MSDs ) are one of the most common occupational disorders around the world .
Although ergonomic design and training are likely to reduce the risk of workers developing work-related upper limb and neck MSDs , the evidence is unclear .
OBJECTIVES To assess the effects of workplace ergonomic design or training interventions , or both , for the prevention of work-related upper limb and neck MSDs in adults .
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
