ABSTRACT
"nBackground and Aim: Application of modern technologies and changes in industries and work practices, particularly in assembly lines, have resulted in increased work-related musculoskeletal disorders (MSDs). This has led to reduced occupational competence in both industrialized and developed countries. This study was conducted to determine the prevalence of MSDs in the upper limbs, postural loading on the upper limbs (using the LUBA technoque), and ergonomic risk factors among assembly workers of an Iranian Telecommunications Manufacturing Company (ITMC) in Shiraz, Iran. "nMaterials and Methods: In this cross-sectional survey data were collected, using the Nordic Musculoskeletal Disorders Questionnaire (NMQ) and LUBA Checklist, on 193 randomly selected registered assembly workers from 8 units of the assembly line of ITMC, Shiraz, Iran. The statistical tests used were as follws: 1.The qui-square test, to determine factors causing MSDs; 2. One-way analysis of variance and Kruskal-Wallis to determine postural loading index; 3. Logistic multiple regression analysis, to determine risk factors. "nResults: Lower-back symptoms were found to be the most prevalent problem (67.9%.) among the workers. The findings also showed that the upper limb disorders were significantly associated with age, sex, job, daily working time, work evironment conditions, and twisting (P
