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 .
Effect of a multidisciplinary program for the prevention of low back pain in hospital employees: a randomized controlled trial.
BACKGROUND Hospital workers with physically dem and ing jobs are at risk for developing recurrent LBP . There is a lack of studies evaluating multidisciplinary prevention of  low back pain ( LBP ) in hospital workers . OBJECTIVE This r and omized controlled trial evaluates the effect of a multidisciplinary prevention program , focusing on a client-centred approach , on hospital workers at risk for developing LBP . METHODS Caregiving hospital workers were allocated to an experimental ( 12-week lasting multidisciplinary prevention program ) or control group ( no intervention ) . They were evaluated prior to the intervention and after a 6 months follow-up period . Primary outcome measures included incidence of LBP , work absenteeism and general health . Secondary outcomes included daily physical activity , job satisfaction and coping strategies . RESULTS A significant improvement was seen for passive coping after 6 months follow-up , but no significant differences were observed between groups in primary or other secondary outcome measures ( p > 0.05 ) . CONCLUSIONS A multidisciplinary prevention program fitting into a bio-psychosocial context may not have been intensive enough to promote a change in daily habitudes , and had no effect on work absenteeism , incidence of LBP or general health . Further research should determine whether prevention of LBP is possible in caregiving personnel
