A cross sectional investigation of musculoskeletal disorder prevalence level among video display terminal users

Abstract

newlineWork related Musculoskeletal disorders (WRMSDs) are increasingly becoming more prevalent in the Indian workforce. The general aim of this cross-sectional study was to analyze the work related MSDs among VDT users in various work settings. The research objectives analyze the critical factors influencing MSD prevalence among VDT users and to determine that the MSD causing risk factors individually or jointly influences musculoskeletal disorders among VDT users in the Indian working population. The MSD prevalence level and its relationship with the Job prevention are studied. Unidimensionality, Reliability and Discriminant analysis are conducted and questionnaire is validated. The validated survey instrument has been to solicit the respondents like Design Engineers, Systems Engineers, Managers, Data Entry Personnels working in Production, Service and Software industries in order to get the perceptions of the respondents. The study was limited to industries in the state of Tamilnadu in South India. Data collected through the structured questionnaire have been processed using SPSS 15.0 package. Descriptive statistics like mean and standard deviations were computed. Pearson s moment Correlation analysis, Simple linear regression analysis, Multiple Regression analysis, Step-wise Regression analysis, t-test and one way ANOVA were performed on variables under study. This research work has developed a MSD risk factor model to test the prevalence of MSD among VDT users. The study has established the relationship between the ergonomic risk factors and the prevalence of MSD among the VDT users. The study has established the relationship between the prevalence of MSD and Job Prevention. The study has brought out various insights of ergonomic problems leading to the prevalence of MSD, which will help the VDT users to overcome the MSD related issues. Thus, the present research has contributed to the literature on the ergonomic field. newline newline newline
