Results Level of evidence from 54 high and medium quality studies showed moderate evidence of a positive effect of physical exercise .
Within this domain , there was strong evidence of a positive effect of workplace strength training .
There was limited evidence for ergonomics and strong evidence for no benefit of participatory ergonomics , multifaceted interventions , and stress management .
No intervention domains were associated with “ negative effects ” .
Conclusions The evidence synthesis recommends that implementing strength training at the workplace can reduce MSD  among workers with physically dem and ing work .
In regard to workplace ergonomics , there was not enough evidence from the scientific literature to guide current practice s. Based on the scientific literature , participatory ergonomics and multifaceted workplace interventions seem to have no beneficial effect on reducing MSD among this group of workers .
Purpose This systematic review investigates the effectiveness of workplace interventions to rehabilitate musculoskeletal disorders ( MSDs ) among employees with physically dem and ing work .
Improving subjective health at the worksite: a randomized controlled trial of stress management training, physical exercise and an integrated health programme.
Our objective was to evaluate the effect of 12 weeks of stress management training ( SMT ) , physical exercise ( PE ) and an integrated health programme ( IHP ) in a worksite setting on subjective health complaints . To do this , we r and omly split 860 employees into the following groups : control ( n = 344 ) , PE ( n = 189 ) , IHP ( comprising physical exercise and health information ) ( n = 165 ) and SMT ( n = 162 ) . There were no significant effects on subjective health complaints , sick leave or job stress . However , strong and specific positive effects were experienced for the particular goal areas defined for each intervention . The PE group showed improved general health , physical fitness and muscle pain , while the SMT group showed improved stress management . The IHP group showed the strongest effects , affecting most goals set for treatment
