Abstract The paper aims primarily to study the sensitivity of Rapid entire body assessment (REBA) and identification of insensitive and sensitive posture zones. The investigative study, and sensitivity analysis of REBA offer deeper insights into the methodology used for the assessment of posture. Full factorial design is divided into parts using a forward approach to access the sensitivity. One parameter is varied keeping other parameters constant to understand its effect on the output score. Combinations of posture where no change was observed were identified. Posture scores were also noted involving sudden jumps. Regression analysis was performed to identify relative importance or weightage of the body and other variables in estimating the final REBA score. The justification of the REBA methodology available in the existing literature is very limited. This paper also demonstrates the need for understanding of REBA method among the researchers. With this paper, ergonomic practitioners can be made aware of insensitive and sensitive zones in posture assessment. Originality This is the first paper that primarily aims to establish the sensitivity of REBA and identifying insensitive postures or problems in REBA assessment. Few research gaps are identified.

快速全身评估 (REBA) 的调查研究和敏感性分析

摘要 本文主要研究快速全身评估（REBA）的敏感性以及不敏感和敏感姿势区的识别。REBA 的调查研究和敏感性分析为用于评估姿势的方法提供了更深入的见解。使用前向方法将全因子设计分为多个部分以获取灵敏度。改变一个参数，保持其他参数不变，以了解其对输出分数的影响。确定没有观察到变化的姿势组合。还记录了涉及突然跳跃的姿势分数。进行回归分析以确定在估计最终 REBA 分数时身体和其他变量的相对重要性或权重。现有文献中可用的 REBA 方法的理由非常有限。这篇论文也证明了研究人员理解 REBA 方法的必要性。通过本文，人体工程学从业者可以了解姿势评估中的不敏感和敏感区域。原创性 这是第一篇主要旨在建立 REBA 的敏感性和识别 REBA 评估中不敏感的姿势或问题的论文。发现的研究空白很少。原创性 这是第一篇主要旨在建立 REBA 的敏感性和识别 REBA 评估中不敏感的姿势或问题的论文。发现的研究空白很少。原创性 这是第一篇主要旨在建立 REBA 的敏感性和识别 REBA 评估中不敏感的姿势或问题的论文。发现的研究空白很少。
