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 .

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 .

Alternating bouts of sitting and standing attenuate postprandial glucose responses.
PURPOSE This study aim ed to examine whether reductions in sitting time through alternating 30-min bouts of sitting and st and ing can reduce postpr and ial glucose , insulin , and triglyceride responses . METHODS Twenty-three overweight/obese sedentary office workers ( 17 males and six females ; mean ± SD : age , 48.2 ± 7.9 yr ; body mass index , 29.6 ± 4.0 kg · m(-2 ) ) undertook two short-term ( 5 d ) experimental conditions in an equal , r and omized ( 1:1 ) order . In a simulated office environment , participants performed typical occupational tasks for 8 h · d(-1 ) while in a 1 ) seated work posture ( control condition ) or 2 ) interchanging between a seated and st and ing work posture every 30 min using an electric , height-adjustable workstation ( intervention condition ) . Fasting and postpr and ial blood sample s after a mixed test drink were collected hourly for 4 h on days 1 and 5 of each condition to assess serum insulin , plasma glucose , and triglycerides . Dietary intake  ( kJ · d(-1 ) ) and physical activity  were st and ardized during each condition . The trial was registered with the Australian New Zeal and Clinical Trials Registry ( ACTRN12611000632998 ) . RESULTS After adjustment for time ( days 1 and 5 ) , incremental area under the analyte time curve differed significantly between conditions for plasma glucose ( P = 0.007 ) but not for serum insulin or plasma triglycerides . Adjusted mean glucose incremental area under the analyte time curve was lowered by 11.1 % after the intervention condition ( 6.38 mM · h(-1 ) ( confidence interval , 5.04 - 7.71 ) ) relative to the control condition ( 7.18 mM · h(-1 ) ( confidence interval , 5.85 - 8.52 ) ) . No temporal changes ( days 1 vs 5 ) between conditions were observed . CONCLUSIONS Alternating st and ing and sitting in 30-min bouts results in modest beneficial effects on postpr and ial glucose responses in overweight/obese office workers
