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 Ergonomic Intervention on Musculoskeletal, Psychosocial and Visual Strain of VDT Data Entry Work: The Polish Part of the International Study
A group of routine data entry operators ( female ) was included in the Polish MEPS ( musculoskeletal — eyestrain— psychosocial — stress ) study . Before the intervention , ergonomic assessment revealed improper working conditions such as inadequate lighting , uncomfortable chairs , and lack of forearm and wrist support while medical examination revealed that trapezius muscle load along with upper arm , head and back angles were higher than advisable . Subjects complained about neck and shoulder pain , visual problems , and psychosocial conditions . The ergonomic intervention included installation of new luminaires and Venetian blinds , new chairs , repair of ventilators , and optometric corrections . The results after the intervention showed mainly improvement in chair comfort , lighting conditions , visual strain , and sitting posture . However , financial limitations did not allow satisfactory completion of the intervention leading to a mixed interpretation of the results
