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 ) .
The cost-effectiveness of a lifestyle physical activity intervention in addition to a work style intervention on recovery from neck and upper limb symptoms and pain reduction in computer workers
Objectives To evaluate the cost-effectiveness of a work style ( WS ) intervention and a work style plus physical activity ( WSPA ) intervention in computer workers with neck and upper limb symptoms compared with usual care . Methods An economic evaluation was conducted from an employer 's perspective and alongside a r and omised controlled trial in which 466 computer workers with neck and upper limb symptoms were r and omised to a WS group ( N=152 ) , a WSPA group ( N=156 ) or a usual care group ( N=158 )  . Total costs were compared to the effects on recovery and pain intensity . In the primary analyses , missing effect data were imputed using multiple imputation techniques . Results Total costs during the 12-month intervention and follow-up period were € 1907 ( WS ) , € 2811 ( WSPA ) and € 2310 ( usual care ) . Differences between groups were not statistically significant . Neither intervention was more effective than usual care in improving overall recovery .  The WS intervention was more effective than usual care in reducing current pain , average pain and worst pain in the past 4 weeks , but the WSPA intervention was not . The acceptability curve showed that when a company is willing to pay approximately € 900 for a 1-point reduction in average pain ( scale from 0 to 10 ) , the probability of cost-effectiveness compared to usual care is 95 % . Similar results were observed for current and worst pain . Conclusions This study shows that the WS intervention was not cost-effective for improving recovery but was cost-effective for reducing pain intensity , although this reduction was not clinical ly significant . The WSPA intervention was not cost-effective compared with usual care . Trial registration number IS RCT N87019406
