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 .

Health-related effects of worksite interventions involving physical exercise and reduced workhours.
OBJECTIVES This study examined the health-related effects of two worksite interventions , physical exercise and reduced workhours , on women employed in dentistry . METHODS Six workplaces were r and omized to one of the following three conditions : ( i ) 2.5 hours of weekly , m and atory physical exercise of middle-to-high intensity to be performed during workhours ( N=62 ) , ( ii ) a reduction of full-time weekly workhours from 40 to 37.5 hours ( N=50 ) , and ( iii ) reference . In all , 177 women participated . Biomarkers and self-ratings in question naires were obtained before the intervention ( T ( 1 ) ) , and six ( T ( 2 ) ) and 12 months ( T ( 3 ) ) after the intervention . RESULTS The results showed increased levels of physical activity and exercise in all of the groups , the level of physical exercise being significantly greater in the physical exercise group . Repeated- measures analyses of variance using data from T ( 1 ) and T (3)for biological measures and all three time points for self-ratings produced significant interaction effects for glucose , waist-to-hip ratio , and work ability and clear trends for general symptoms and upper-extremity disorders . Posthoc analyses showed that the results of the health-related measures differed between the interventions , decreased glucose and upper-extremity disorders in the exercise group , and increased high-density lipoprotein and waist-to-hip ratio among those working reduced hours . CONCLUSIONS These results show that the two interventions had small and varied effects on biomarkers and self-reports of different aspects of health among women . It is suggested that interventions involving a modest reduction in workhours seem to be more effective if these hours are used for physical exercise
