Levels of evidence for interventions associated with positive effects were : Moderate evidence for arm supports ; and Limited evidence for ergonomics training plus workstation adjustments , new chair and rest breaks .
Levels of evidence for interventions associated with “ no effect ” were : Strong evidence for workstation adjustment alone ; Moderate evidence for biofeedback training and job stress management training ; and Limited evidence for cognitive behavioral training .
No interventions were associated with “ negative effects ” .
Conclusion It is difficult to make strong evidence d-based recommendations about what practitioners should do to prevent or manage upper extremity MSDs .
There is a paucity of high quality OHS interventions evaluating upper extremity MSDs and none focused on traumatic injury outcomes or workplace m and ated pre-placement screening exams .
Background Little is known about the most effective occupational health and safety ( OHS ) interventions to reduce  upper extremity musculoskeletal disorders ( MSDs ) and injuries .
Methods A systematic review used a best evidence synthesis approach to address the question : “ do occupational health and safety interventions have an effect on upper extremity musculoskeletal symptoms , signs , disorders , injuries , cl aims and lost time ? ”
Group Training with Healthy Computing Practices to Prevent Repetitive Strain Injury (RSI): A Preliminary Study
This pilot study investigated whether group training , in which participants become role models and coaches , would reduce discomfort as compared to a nontreatment Control Group . Sixteen experimental participants participated in 6 weekly 2-hr group sessions of a Healthy Computing program whereas 12 control participants received no training .  None of the participants reported symptoms to their supervisors nor were they receiving medical treatment for repetitive strain injury prior to the program . The program included training in ergonomic principles , psychophysiological awareness and control , sEMG practice at the workstation , and coaching coworkers . Using two-tailed t tests to analyze the data , the Experimental Group reported ( 1 ) a significant overall reduction in most body symptoms as compared to the Control Group and ( 2 ) a significant increase in positive work-style habits , such as taking breaks at the computer , as compared to the Control Group . This study suggests that employees could possibly improve health and work style patterns based on a holistic training program delivered in a group format followed by individual practice
