The rubber processing workers experience various types of musculoskeletal disorders (MSDs) due to awkward postures, repetitive movements, and manual loads etc. Research on MSDs and ergonomic interventions in this area is limited. Therefore, the present systematic review aims to (i) identify various operations done by rubber processing workers and their associated MSDs, (ii) explore the ergonomic intervention and post-intervention study and its impact among the workers, (iii) identify the research gaps in MSDs and ergonomic interventions through bibliometric analysis.
Comprehensive electronic searches were conducted in Web of Science, ScienceDirect and PubMed for the search term "Ergonomics" or "Musculoskeletal disorder" and "Rubber" for the article published before 2020. Eleven papers were identified for the review of MSDs and ergonomic interventions; data were extracted to summarize sample size, data collection methods, analyzing tools, various operations, MSDs, and ergonomic interventions.
The reviewed article is classified according to various operations such as rubber tapping, latex collection, rubber sheeting and sheet pressing. The review reveals that most of the workers experience lower back pain, which involved a traditional way of operating. Every author is trying to recommend some interventions, but post-intervention studies are limited.
Due to the limited post-intervention study, there is a scope of ergonomic interventions in every operation. So, the implementation of a proper ergonomic tool with adequate awareness improves the MSDs among the rubber processing workers. The review will help to identify the various intervention gaps in different operations associated with rubber farming.
由于姿势不当、重复动作和手动负荷等原因,橡胶加工工人会经历各种类型的肌肉骨骼疾病(MSD)。针对该领域的 MSD 和人体工程学干预措施的研究有限。因此,本系统评价旨在:(i)确定橡胶加工工人所进行的各种操作及其相关的 MSD;(ii)探索人体工程学干预措施及其对工人的影响;(iii)通过文献计量分析确定 MSD 和人体工程学干预措施方面的研究空白。
在 Web of Science、ScienceDirect 和 PubMed 中全面检索“人体工程学”或“肌肉骨骼疾病”和“橡胶”的检索词,以获取 2020 年前发表的文章。确定了 11 篇有关 MSD 和人体工程学干预措施的综述文章,提取数据以总结样本量、数据收集方法、分析工具、各种操作、MSD 和人体工程学干预措施。
综述文章根据橡胶开炼、胶乳采集、橡胶片材和片材压制等不同操作进行分类。综述结果表明,大多数工人都经历过腰痛,这涉及传统的操作方式。每位作者都试图推荐一些干预措施,但干预后研究有限。
由于干预后研究有限,每种操作都有进行人体工程学干预的空间。因此,实施适当的人体工程学工具并提高工人的认识,可以改善橡胶加工工人的 MSD。该综述将有助于确定与橡胶种植相关的不同操作中各种干预措施的差距。
