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 hamstring stretch with pelvic control on pain and work ability in standing workers.
BACKGROUND Hamstring tightness induces posterior pelvic tilt and decreased lumbar lordosis , which can result in low back pain OBJECTIVE : We investigated effects of hamstring stretch with pelvic control on pain and work ability in st and ing workers . METHODS One hundred adult volunteers from a st and ing workers were r and omly assigned to pelvic control hamstring stretching ( PCHS ) ( n = 34 ) , general hamstring stretching ( GHS ) ( n = 34 ) , control ( n = 32 ) groups . The control group was performed self-home exercise . All interventions were conducted 3 days per week for 6 weeks , and included in the hamstring stretching and lumbopelvic muscle strengthening . Outcomes were evaluated through the visual analog scale ( VAS ) , straight leg raise test ( SLR ) , sit and reach test ( SRT ) , Oswestry disability index ( ODI ) , and work ability index ( WAI ) . RESULTS Significant difference in VAS , SLR , SRT , ODI , and WAI were found in the PCHS and GHS groups . The control group was a significant difference only in ODI . The PCHS group showed a greater difference than the GHS group and control group in VAS , SLR , SRT , and ODI . CONCLUSIONS The pelvic control hamstring stretch exercise would be more helpful in back pain reduction and improvement of work ability in an industrial setting
