The present investigation was aimed to assess the postural stress and the prevalence of musculoskeletal disorders (MSDs) of the "Jari" (golden thread) workers.
This cross-sectional study was carried out on 156 female workers in different areas of the Purba Medinipur, Paschim Medinipur, and Howrah districts of West Bengal, India.
The MSDs of the workers were evaluated by modified Nordic questionnaire method. The postural pattern during work was assessed by direct observation method. The posture of Jari workers has been analyzed by OWAS, REBA, and RULA methods. The joint angle in normal and working posture was observed.
The prevalence of MSDs was very high among the workers. The major locations of body pains in Jari workers were lower back, upper back, neck, wrist, thigh, and shoulder. The occurrence of MSDs was higher in lower and higher age group than that of the middle age group. The total work shift of the workers was approximately 13 h including rest pause. The dominant postures adopted by the workers were sitting on the floor with stretched legs, sitting on the floor with folded knees, and kneeling posture. From the results of the postural analysis, the postures of the Jari workers had been categorized as stressful. There were a significant deviation between normal standing angles and working angles. From the overall study, it may be concluded that adoption of stressful postures for longer duration might be the cause of MSDs in different body parts of the Jari workers.
本调查旨在评估“扎里”（金线）工人的姿势压力和肌肉骨骼疾病（MSD）的患病率。
本横断面研究针对印度西孟加拉邦普尔巴梅迪尼布尔、西梅迪尼布尔和豪拉地区不同区域的156名女工开展。
采用改良的北欧问卷法评估工人的肌肉骨骼疾病。通过直接观察法评估工作期间的姿势模式。采用OWAS、REBA和RULA方法分析扎里工人的姿势。观察正常姿势和工作姿势下的关节角度。
工人中肌肉骨骼疾病的患病率非常高。扎里工人身体疼痛的主要部位是下背部、上背部、颈部、手腕、大腿和肩部。低年龄组和高年龄组肌肉骨骼疾病的发生率高于中年组。工人的总工作班次约为13小时，包括休息时间。工人采用的主要姿势是伸直腿坐在地板上、屈膝坐在地板上和跪姿。从姿势分析结果来看，扎里工人的姿势被归类为有压力的姿势。正常站立角度和工作角度之间存在显著偏差。从总体研究来看，可以得出结论，长时间采用有压力的姿势可能是扎里工人身体不同部位肌肉骨骼疾病的原因。
