การพัฒนาแบบประเมินความเสี่ยงทางการยศาสตร์สำหรับคนกรีดยางพารา

Abstract

Risk assessment for the Musculoskeletal disorder (MSDs) by observation is popular and widely used. However, appropriate tool that can assess for all working factors and working environments is limited. Therefore, this research focuses on applying ergonomic principles to rubber tapping with two main objectives: (1) to analyze the factors affecting the fatigue of rubber tappers and (2) to develop a tool to assess the risk of rubber tappers. The results of the analysis revealed that the factors affecting the fatigue of rubber tapping were cutting height, inclination of plantation area and stroke of rubber tapping. The Ergonomic Risk Assessment tool in Rubber Tappers (EART) was developed accurately isolate without the need for cumbersome tools. The reliability analysis of the EART revealed that the Inter-rater reliability and Intra-rater reliability fall in very good level. The EART assessment tool is fullprove and able to identify the rubber tapping person with back pain and without back pain (p-value < 0.001).
