Manual meat cutters in India are at high risk of work-related musculoskeletal disorders (WMSDs) for a variety of reasons including holding awkward postures, repetitive forceful exertions, and inadequate rest. This is the first study of its kind to investigate the nature and magnitude of WMSDs among manual meat cutters in India.
The aim of this study was to measure the ergonomic risk factors for WMSDs among adult male manual meat cutters working in Jabalpur, India.
We used direct observation, activity analysis, questionnaires, interviews, photography, and video to measure the quantitative ergonomic risk factors.
Ovako working posture analysis indicated high scores (four for the back in peeling, six for the arms in cutting, and six for the arms during mincing tasks). Rapid entire body assessment method (REBA) scores were also high at 10/10 for deboning and mincing tasks, all associated with repetitive movements of the arms and awkward posture of the upper part of the body.
The study indicates that most tasks for meat cutters fall in the high-risk category for occupational injury. Results suggest that ergonomic interventions that address retooling and workstation and process redesign would be useful in reducing the number of injuries.
印度的手工切肉工人因各种原因面临与工作相关的肌肉骨骼疾病（WMSDs）的高风险，这些原因包括保持 awkward 姿势、重复性用力以及休息不足。这是同类研究中首次调查印度手工切肉工人中 WMSDs 的性质和程度。
本研究的目的是测量在印度贾巴尔普尔工作的成年男性手工切肉工人中 WMSDs 的人体工程学风险因素。
我们使用直接观察、活动分析、问卷调查、访谈、摄影和视频来测量定量人体工程学风险因素。
奥瓦科工作姿势分析显示高分（剥皮时背部为 4 分，切割时手臂为 6 分，切碎任务时手臂为 6 分）。快速全身评估方法（REBA）在去骨和切碎任务中的得分也很高，为 10/10，所有这些都与手臂的重复运动和身体上部的 awkward 姿势有关。
该研究表明，切肉工人的大多数任务属于职业伤害的高风险类别。结果表明，解决重新装备以及工作站和流程重新设计问题的人体工程学干预措施将有助于减少伤害数量。
