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 .
Efficacy of 'Tailored Physical Activity' on reducing sickness absence among health care workers: A 3-months randomised controlled trial.
AIM The aim was to evaluate efficacy of " Tailored Physical Activity " ( TPA ) versus a reference group ( REF ) in reducing the number of self-reported days of sickness absence for health care workers in the Sonderborg Municipality . METHODS In this r and omised controlled trial , all participants ( n = 54 ) received health guidance for 1.5 h  and were r and omised to TPA or REF . The primary aim was to make a comparison of participants ' self-reported sickness absence due to musculoskeletal troubles measured three months after baseline . Secondary outcomes included anthropometric , health-related and physical capacity measures . RESULTS A TPA intervention was not significantly more effective than REF in reducing sickness absence caused by musculoskeletal troubles . However , there were significant improvements for TPA participants compared to REF in reducing pain intensity from 47.9 mm to 21.8 mm ( p < .01 ) , increasing work ability from 7.3 to 8.1 ( p = .04 ) and decreasing kinesiophobia from 26.7 to 22.5 ( p < .01 ) . A trend towards a significant improvement was seen for aerobic capacity while no effect of the intervention was found on productivity , BMI or grip strength . CONCLUSION This physical activity intervention is a promising initiative for health care workers since participants achieved a substantial effect on their experience of pain , on their work ability and on their fear of physical movement relating to pain . Moreover , a difference in aerobic capacity was apparent between the sample groups . TPA however , had no significant effect in reducing sickness absence days
