Abstract

The purpose of this study was to determine whether the introduction of a modular work system -reputed to reduce injuries caused by repetitive movements- in the garment sector actually results in significant changes to tasks and movements. Observations were made of operators producing garments in two companies using both conventional and modular production systems, and data collected on the real distribution of tasks, upper limb activity and work organization under both systems. Operators working under the modular system were more multi-skilled than expected. The modular system was also associated with a total reorganization of operations. This study was one of the first to examine the real effect of modular work on the upper limbs. Its results provide decision-makers with tools with which to evaluate the effectiveness of modular work systems in preventing musculoskeletal disorders.
