Background: The purpose of this study is to describe the kinematic characteristics of manual weaving related to the biomechanical risk factors for musculoskeletal disorders.
Methods: Twelve professional female weavers participated in this study. The video recording of their workstations was performed perpendicularly in the sagittal and transverse
planes in a synchronized manner, at about 2.45 m and for 5 minutes. The videos were then analyzed using the Kinove software. Statistical processing by the statistical SPSS 22 software.
Results: The results identified a succession of cycles, each with two important phases called the “interlacing” phase and the “winding/adjustment” phase. The average cycleBtime is 127.9 ± 11.7 seconds. The “interlacing” phase is the longest and concerns an average 80% of the cycle time or 103.5 ± 35.9 seconds. The segmental movements are
mainly flexion-extension type with angular variations constantly above the acceptable limits. It is the same for the repetitiveness of the movements which solicit the upper
limb and the trunk particularly.
Conclusions: These results recommend one of the actions to prevent musculoskeletal disorders including instructions on postures and frequencies of weaving movements as
well as physical exercises adapted to the physical needs of practitioners.
