Physical and organisational risk factors associated to work-related musculoskeletal disorders in textile industry

Abstract

Work-related musculoskeletal disorders (WRMD) affect workers in several occupations and are one of the major health problems in many countries. This study was developed in two sectors of a textile industry, one of them being technologically more advanced. The objectives were to identify physical and organizational risk factors associated to WRMD in the two sectors and estimate prevalence of pain among these workers. The workplace and working activity of 12 individuals were observed on ergonomic grounds, and 50 workers answered a questionnaire. The following physical risk factors were identified: awkward shoulder postures, standing work position, repetitive movements, and unfavourable environmental features. Main organizational risk factors identified were: intense work pace, uneven and repetitive tasks, absence of pauses and impossibility of communication with peers. Pain symptoms prevalence of 60% and 76% was found in the two sectors. Conclusion shows that investments in technology that do not follow changes in work condition and organization may result in maintenance or aggravation of risk situations associated to WRMD.
