Influence Of Video Display Terminal User's Qualification On The Level Of Musculoskeletal Disorder Prevalence

摘要

The use of Video Display Terminal (VDT) is widespread and beneficial for improvement of work quality and productivity. Musculoskeletal symptoms or disorders in the upper extremities and neck among employees working at video display terminal workstations has been a topic in occupational health research for many years. This study has developed a MSD prevalence model suitable for computer workplaces in India. A total of about 600 questionnaires were distributed to the VDT users of production, software and service industries. Out of total 600 questionnaires distributed, 427 were collected with the response rate of 71.16% of the respondents. Out of 427, only 410 samples were found to contain complete information and so were valid for analysis. To check whether qualification of computer users play a significant role on the perception level of the Musculoskeletal Disorder (MSD) causing risk variables, MSD prevalence level and Job Prevention, a hypothesis H_1 was framed and tested. One way ANOVA has been conducted and the result shows that the Equipment Setup and the Assumed Posture are found significant for VDT users with different qualifications and Diploma qualified VDT users are satisfied with the existing Equipment Setup and alter the body posture in better manner than the remaining qualification groups.
