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 effectiveness of participatory ergonomics to prevent low-back and neck pain--results of a cluster randomized controlled trial.
OBJECTIVE The aim of this r and omized controlled trial ( RCT ) was to investigate the effectiveness of the Stay@Work participatory ergonomics ( PE ) program to prevent low-back and neck pain . METHODS A total of 37 departments were r and omly allocated to either the  intervention ( PE ) or control group ( no PE ) . During a six-hour meeting , working groups followed the PE steps and composed and prioritized ergonomic measures aim ed at preventing low-back and neck pain . Subsequently , working groups were requested to implement the ergonomic measures in the departments . The primary outcomes were low-back and neck pain prevalence and secondary outcomes were pain intensity and duration . Data were collected by question naires at baseline , and after 3- , 6- , 9- , and 12-months follow-up . Additionally , the course of low-back and neck pain ( transitions from no symptoms to symptoms and from symptoms to no symptoms ) was modeled . RESULTS The r and omization procedure result ed in 19 intervention departments ( N=1472 workers ) and 18 control departments ( N=1575 workers ) . After 12 months , the intervention was not more effective than the control group in reducing the prevalence of low-back and neck pain or reducing pain intensity and duration .  PE did not increase the probability of preventing low-back pain [ odds ratio ( OR ) 1.23 , 95 % confidence interval ( 95 % CI ) 0.97 - 1.57 ) or neck pain ( OR 1.01 , 95 % CI 0.74 - 1.40 ) . However , PE increased the probability of recovering from low-back pain ( OR 1.41 , 95 % CI 1.01 - 1.96 ) , but not from neck pain ( OR 0.95 , 95 % CI 0.72 - 1.26 ) . CONCLUSION PE neither reduced low-back and neck pain prevalence nor pain intensity and duration nor was it effective in the prevention of low-back and neck pain or the recovery from neck pain . However , PE was more effective in the recovery from low-back pain
