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 .
Participatory organizational intervention for improved use of assistive devices in patient transfer: a single-blinded cluster randomized controlled trial.
Objectives This r and omized controlled trial ( RCT ) evaluated the effect of a participatory organizational intervention for improved use of assistive devices ( AD ) in patient transfer . Methods We r and omly allocated 27 departments from five hospitals in Denmark to a participatory intervention ( 14 clusters , 316 healthcare workers ) or a control group ( 13 clusters , 309 healthcare workers ) . The intervention consisted of 2 × 2 hour workshops with managers , the hospital 's health and safety staff , and 2 - 5 healthcare workers from each department . Based on an assessment of barriers and solutions conducted prior to r and omization , participants developed an action plan for implementing department-specific solutions for improving the use of AD . Use of necessary AD ( using digital counters as primary outcome ) , and general use of AD ( using accelerometers as secondary outcome ) , pain intensity in the low-back , work-related back injuries during patient transfer , and communication and guidance in the use of AD were measured at baseline , 6 and 12 months . Results Use of necessary AD ( primary outcome ) , low-back pain , and back injuries did not change in the intervention compared with control group at 12-month follow-up . However , general use of AD measured with accelerometers as well as communication and guidance improved significantly in the intervention versus control group . Conclusion The intervention did not result in more frequent use of the necessary AD but led to more general use of AD , as well as increased communication and guidance
