Limited evidence was also found for a causal relationship between  computer work per se and computer mouse time related to tension neck syndrome , but the evidence for keyboard time was insufficient .
Insufficient evidence was found for an association between other musculoskeletal diagnoses of the neck and upper extremities , including shoulder tendonitis and epicondylitis , and any aspect of computer work .
Conclusions There is limited epidemiological evidence for an association between aspects of computer work and some of the clinical diagnoses studied .
Background This review examines the evidence for an association between  computer work and neck and upper extremity disorders ( except carpal tunnel syndrome ) .
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
