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 ) .
Participatory ergonomics to reduce exposure to psychosocial and physical risk factors for low back pain and neck pain: results of a cluster randomised controlled trial
Objectives This study investigated the effectiveness of the Stay@Work participatory ergonomics programme to reduce workers′ exposure to psychosocial and physical risk factors . Methods 37 departments ( n=3047 workers ) from four Dutch companies participated in this cluster r and omised controlled trial ; 19 ( n=1472 workers ) were r and omised to an intervention group ( participatory ergonomics ) and 18 ( n=1575 workers ) to a  control group ( no participatory ergonomics ) . During a 6 h meeting guided by an ergonomist , working groups devised ergonomic measures to reduce psychosocial and physical workload and implemented them within 3 months in their departments . Data on psychosocial and physical risk factors for low back pain and neck pain were collected at baseline and after 6 months . Psychosocial risk factors were measured using the Job Content Question naire and physical risk factors using the Dutch Musculoskeletal Question naire . Intervention effects were studied using multilevel analysis . Results Intervention group workers significantly increased on decision latitude ( 0.29 points ; 95 % CI 0.07 to 0.52 ) and decision authority ( 0.16 points ; 95 % CI 0.04 to 0.28 ) compared to control workers . However , exposure to awkward trunk working postures significantly increased in the intervention group ( OR 1.86 ; 95 % CI 1.15 to 3.01 ) compared to the control group . No significant differences between the intervention and control group were found for the remaining risk factors . After 6 months , loss to follow-up was 35 % in the intervention group and 29 % in the control group . Conclusion Participatory ergonomics was not effective in reducing exposure to psychosocial and physical risk factors for low back pain and neck pain among a large group of workers .
