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 ) .
The Effect of Worksite Physical Activity Intervention on Physical Capacity, Health, and Productivity: A 1-Year Randomized Controlled Trial
Objective : To investigate the effect of two contrasting physical activity worksite interventions versus a reference intervention ( REF ) on various health outcomes . Methods : A 1-year r and omized controlled trial was conducted with specific resistance training ( SRT ) , all-round physical exercise ( APE ) , and REF . Results : SRT and APE compared with REF showed significant reductions in systolic blood pressure ( ∼6 mm Hg ) , body fat percentage ( ∼2.2 body fat% ) , as well as shoulder and back pain ( ∼30 % reduction in duration ) . Muscle strength ( APE and SRT ) and maximal oxygen uptake ( APE ) increased approximately 10 % . Conclusions : Worksite intervention with both SRT as well as APE is recommended , since these activities compared with REF result ed in clinical ly relevant reductions of cardiovascular and metabolic syndrome-related risk factors as well as musculoskeletal pain symptoms , in combination with minor increases in physical capacity
