The sand core making process is performed manually in West Bengal involving a large number of workers of lowest economic strata. The core making workers most often work for a prolonged period of time and they are forced to handle various amounts of heavy load during the entire period of work. In this study an attempt was made to identify the work related musculoskeletal disorders among the sand core-making workers. Fifty male workers engaged in carbon dioxide and chemical core making work at an unorganized sector at Baruipur, Calcutta were randomly selected for this study. A detailed modified Nordic questionnaire study on discomfort feeling was performed among the core making workers. REBA method was applied to analyze the working posture. Finally, discomfort level and risk level of the individual working postures were calculated by the use of risk level and discomfort level scale. From the questionnaire study it was revealed that most of the core making workers grind often in awkward postures. The workers were affected by musculoskeletal disorders like pain at low back (100%), hand (40%), shoulder (30%), wrist (20%) and neck (20%). It has been also found that there is a significant (p < 0.05) correlation between discomfort level and risk level of the individual working postures of the workers. It was concluded from the study that health of the core-making workers was highly affected by different awkward postures and that they suffer from posture-related musculoskeletal disorders primarily affecting the low back region.
在西孟加拉邦，砂芯制作过程是手工进行的，涉及大量经济阶层最低的工人。砂芯制作工人通常长时间工作，并且在整个工作期间被迫搬运各种重物。在本研究中，试图识别砂芯制作工人中与工作相关的肌肉骨骼疾病。随机选择了加尔各答巴鲁伊布尔一个无组织部门中从事二氧化碳和化学芯制作工作的50名男性工人进行这项研究。对砂芯制作工人进行了一项关于不适感的详细改良北欧问卷研究。应用REBA方法分析工作姿势。最后，通过使用风险水平和不适水平量表计算个体工作姿势的不适水平和风险水平。从问卷研究中发现，大多数砂芯制作工人经常以 awkward姿势研磨。工人受到肌肉骨骼疾病的影响，如腰痛（100%）、手部疼痛（40%）、肩部疼痛（30%）、手腕疼痛（20%）和颈部疼痛（20%）。还发现，工人个体工作姿势的不适水平和风险水平之间存在显著（p < 0.05）相关性。从研究中得出结论，砂芯制作工人的健康受到不同 awkward姿势的高度影响，并且他们患有主要影响下背部区域的与姿势相关的肌肉骨骼疾病。
