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 wearable type lumbosacral support for low back pain among hospital workers: A randomized controlled trial
Objective : To examine the effects of a new wearable type of lumbosacral support on low back pain . Methods : A total of 121 healthcare workers participated in this study . They were r and omly allocated into the experimental and control groups and the former wore the support with signals of compression on the back by poor posture for the first 3 months . The control group remained on a waiting list for the first 3 months . Medical history , musculoskeletal symptoms , feeling in good posture , sleep habits , psychological distress , Rol and -Morris Disability Question naire , and Somatosensory Amplification Scale ( SSAS ) were evaluated . The range of motion ( ROM ) in the shoulder and hip joints as well as spinal alignment were evaluated . Our primary concern was the difference in the change of low back pain measured by visual analog scale ( VAS ) between the two groups . Results : A total of 54 participants in the experimental and 53 participants in the control groups were analyzed . VAS and SSAS scores as well as lumbar spinal ROM in the experimental group significantly decreased . Low back pain ( OR=0.401 , 95 % CI=0.168 - 0.954 ) and neck pain in the experimental group ( OR=0.198 , 95 % CI=0.052 - 0.748 ) significantly decreased . Conclusions : The new lumbar support reduced VAS and SSAS scores , lumbar spinal ROM , low back pain , and neck pain . This new type of lumbar support reduced low back pain among healthcare workers
