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 ? ”
The Effect of an Ergonomie Intervention on Musculoskeletal, Psychosocial and Visual Strain of VDT Data Entry Work: The Norwegian Part of the International Study
The Norwegian MEPS ( musculoskeletal — eyestrain — psychosocial — stress ) study included 3 groups : data entry , data dialogue ( female ) and data dialogue  ( male ) . Before intervention , the data entry group reported significantly more symptoms and signs of musculoskeletal illness and had longer periods in front of the video display terminal ( VDT ) without a break . The ergonomic intervention consisted mainly of ergonomic information and training . After intervention , the data dialogue female group reported a significant reduction in shoulder pain in parallel with a reduction in trapezius load . Increasing the underst and ing in how to adjust the work st and and chair may have been contributing factors to reducing the pain level . There was a significant reduction in eye problems in all groups ; the greatest reduction in eye symptoms was seen in the groups who had new optometric corrections
