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 ) .
Musculoskeletal symptoms and job satisfaction among office-workers: a cross-sectional study from Iran.
OBJECTIVE Office-work poses a high-risk for musculoskeletal disorders ( MSDs ) , with consequences for workers , employers and society . The aims of this study were to determine the prevalence of musculoskeletal symptoms in a sample of Iranian office workers , to investigate the association between pain severity and job satisfaction and to investigate the association between MSDs and job satisfaction . MATERIAL S AND METHODS Iranian office workers from a university setting ( n=91 ) were r and omly selected and included in this cross-sectional study . The  Nordic musculoskeletal question naire plus visual analogue scale of pain  , and the Brayfield-Rothe Job Satisfaction Index  were used to study the prevalence of MSDs , pain intensity and job satisfaction , respectively . Descriptive analysis , Pearson 's correlation , and multiple regression analysis were performed for statistical assessment . RESULTS Eighty-nine percent of participants reported musculoskeletal symptoms during the past 12 months , most commonly in the neck ( 69.2 % ) , low back ( 58.2 % ) , knees ( 41.8 % ) , shoulders ( 35.2 % ) , and upper back ( 34.1 % ) . There was a significant negative correlation between pain intensity and job satisfaction . Pain intensity , low-back pain in the last week , wrist pain in the past 12 months and shoulder pain were significantly associated with job satisfaction ( p<0.05 ) . CONCLUSION This study provides evidence that musculoskeletal symptoms are common in Iranian office workers , associated with low job satisfaction . These findings indicate the need for more attention to MSDs among office workers and design ing effective preventive interventions
