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 .
Effects of a Worksite Supervised Adapted Physical Activity Program on Trunk Muscle Endurance, Flexibility, and Pain Sensitivity Among Vineyard Workers
ABSTRACT Objectives : In viticulture , the prevalence of low back pain is particularly high among vineyard workers exposed to sustained and awkward postures . One promising setting for low back pain prevention resides in the implementation of workplace physical activity . Methods : This nonr and omized pilot study aims at evaluating the effects of a worksite supervised adapted physical activity program among 17 vineyard workers volunteered to enter either an intervention group ( n = 10 ) or a control group ( n = 7).The intervention group followed a physical activity program for 8 weeks involving ( 1 ) 15 minutes of warm-up every working day and ( 2 ) two weekly 1-hour adapted physical activity sessions targeting trunk muscle endurance and flexibility . The control group was advised to continue normal physical activity . Evaluations were carried out at weeks 0 , 4 , 8 , and 12 . Physical capacity was assessed using flexibility tests for the trunk , along with trunk muscle flexor and extensor endurance tests . Finally , pain sensitivity was evaluated by assessing pressure pain thresholds over 14 anatomical locations in the low back region . Results : For the intervention group , the endurance of the trunk extensor and flexor significantly increased from baseline to week 8 as well as the pressure pain thresholds . No change was observed for the control group over the same period . Conclusions : These encouraging results in combination with the high adherence rate set interesting foundations for the promotion of worksite supervised adapted physical activity and , most likely , offer a new promising approach to prevent low back pain among vineyard workers
