The aim of this work was to study the prevalence of neck- upper extremity musculoskeletal disorders (MSD), mainly carpal tunnel syndrome (CTS), among video display terminal(VDT) users and to determine the association between CTS and occupational physical and psychosocial risk factors. A comparative cross- sectional study was conducted
upon (60) VDT users (at risk group) and a matched control group composed of (35) non-VDT users. The population studied was subjected to a structured questionnaire, clinical examination, and investigation in the form of electrophysiological studies and of neck X- ray. There was no statistically significant difference in the prevalence
of neck -upper extremity MSD during the past year between the two groups. The prevalence of CTS among the VDT users was 3.3% which was similar to that found in other studies. The mean age of CTS cases (58±1.4years) was statistically significantly higher than the symptom- free VDT users (45.8±4.6years). The physical work stressors
and psychosocial factors were more common among CTS cases compared to non-cases, however, the difference was not statistically significant.
