There was strong evidence for one intervention category , resistance training , leading to the recommendation : Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms .
The synthesis also revealed moderate evidence for stretching programmes , mouse use feedback and forearm supports in preventing UEMSD or symptoms .
There was also moderate evidence for no benefit for EMG biofeedback , job stress management training , and office workstation adjustment for UEMSD and symptoms .
The burden of disabling musculoskeletal pain and injuries ( musculoskeletal disorders , MSDs ) arising from work-related causes in many workplaces remains substantial .
There is little consensus on the most appropriate interventions for MSDs .
Our objective was to up date a systematic review of workplace-based interventions for preventing and managing  upper extremity MSD ( UEMSD ) .
A new bricklayers' method for use in the construction industry.
OBJECTIVES The aim of this study was to investigate the effect of raised bricklaying on physical workload , reported musculoskeletal disorders , sickness absence , and job satisfaction . METHODS A controlled intervention study with a follow-up period of 10 months was performed among 202 bricklayers from 25 construction companies . RESULTS The introduction of devices for raised bricklaying decreased the physical load on the lower back and , to a less extent , on the shoulders and upper extremities . Although raised bricklaying had no effect on the number of lifts , decreases in trunk bending lowered the biomechanical moment . The results showed no decrease in reported musculoskeletal symptoms as a result of the adoption of raised bricklaying . Irrespective of the reason(s ) , the percentage of bricklayers in the intervention group reporting sickness absence was significantly lower than the same percentage in the control group . The results also showed that , in general , the bricklayers in this study were very satisfied with the use of devices for raised bricklaying . CONCLUSIONS Controlled intervention studies on ergonomic improvements are rare . This study shows that the introduction of an ergonomic improvement in the construction industry may reduce physical load and the incidence of sickness absence
