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 .

The Effectiveness of a Web-Based Computer-Tailored Intervention on Workplace Sitting: A Randomized Controlled Trial
Background Effective interventions to influence workplace sitting are needed , as office-based workers demonstrate high levels of continued sitting , and sitting too much is associated with adverse health effects . Therefore , we developed a theory-driven , Web-based , interactive , computer-tailored intervention aim ed at reducing and interrupting sitting at work . Objective The objective of our study was to investigate the effects of this intervention on objective ly measured sitting time , st and ing time , and breaks from sitting , as well as self-reported context -specific sitting among Flemish employees in a field-based approach . Methods Employees ( n=213 ) participated in a 3-group r and omized controlled trial that assessed outcomes at baseline , 1-month follow-up , and 3-month follow-up through self-reports . A sub sample ( n=122 ) were willing to wear an activity monitor ( activPAL ) from Monday to Friday . The tailored group received an automated Web-based , computer-tailored intervention including personalized feedback and tips on how to reduce or interrupt workplace sitting . The generic group received an automated Web-based generic advice with tips . The control group was a wait-list control condition , initially receiving no intervention . Intervention effects were tested with repeated- measures multivariate analysis of variance . Results The tailored intervention was successful in decreasing self-reported total workday sitting ( time × group : P<.001 ) , sitting at work ( time × group : P<.001 ) , and leisure time sitting ( time × group : P=.03 ) , and in increasing objective ly measured breaks at work ( time × group : P=.07 ) ; this was not the case in the other conditions . The changes in self-reported total nonworkday sitting , sitting during transport , television viewing , and personal computer use , objective ly measured total sitting time , and sitting and st and ing time at work did not differ between conditions . Conclusions Our results point out the significance of computer tailoring for sedentary behavior and its potential use in public health promotion , as the effects of the tailored condition were superior to the generic and control conditions .
