Objective: To assess the effect of ergonomics improvements on carpet weavers's upper trapezius fatigue. Design: The carpet weavers with the following criteria will be included in the study: age of 20-40 years old; not having musculoskeletal disorders, acute disease, surgery records. Intervention: carpet weavers will evaluate into traditional and interventional stages with crossover assignment. That former situation defined as work in common workstation and the later one is working in ergonomics workstation. Main outcome measures: effect of each workstation on upper trapezius fatigue, using BPDR self-reporting and EMG parameters.
