Abstract

Bulletin of Faculty of Physical Therapy 2017, 22:23–26 Background Assessment of the level of exposure to work-related musculoskeletal disorders (WMSDs) risk factors can be an appropriate basis for planning and implementing an interventional ergonomics program in the workplace. This study was conducted among workers of Nag Hammadi sugar factory to investigate the relation between prevalence of WRSDs and years of job experience among factory workers. Materials and methods A total of 109 workers were selected from Nag Hammadi sugar factory and included in the study. The Nordic musculoskeletal questionnaire was used to study the prevalence of WMSDs. Results The statistical analysis has shown that there was no statistically significant difference of WMSDs prevalence in participants and years of job experience in all body regions except for upper back. Workers who have worked for 6–10 years showed a significant prevalence of upper back pain than those who worked less than 5 years (P<0.05). Conclusion Ergonomic interventions and education programmes that might improve the working conditions may be necessary to decrease upper back trouble in those worker population.
