Abstract

The purpose of ergonomics is to take advantage of human ability limits in order to implement an efficient and comfortable interface to use. When the worker is performing an improper posture, it may cause the worker to feel discomfort when doing the work and may lead to getting musculoskeletal disorders (MSDs). According to past research, there is a relationship between improper working posture and MSDs. The objective of this study was to determine the relationship between improper working posture at maintenance workers using different assessment methods. CMDQ, RULA, REBA and ENBORA were conducted among 34 maintenance workers around Parit Raja, Johor. The selected maintenance workers were interviewed via CMDQ and RULA, REBA and ENBORA were conducted based on their working posture at the time of the interview. The data were analysed and compared based on similar observed body parts. Among the respondents, lower back discomfort was most prevalent (70.59%), followed by right and left shoulders (58.82% and 55.88%, respectively) as well as right wrist (29.47%) and left wrist (55.88%). The mean RULA Score for the respondents was 4.76 (SD=1.37), which indicates a medium risk level. The mean REBA Score for the respondents was 7.41 (SD=2.26), which indicates the average REBA risk level was high. The mean value for the ENBORA Final Score was 33.56 (SD=11.98), indicating that the respondents overall have a negligible risk of getting MSD based on their working posture. The body parts compared in CMDQ, RULA, REBA and ENBORA were neck, upper arm, lower arm, wrist and trunk. Based on findings, ENBORA has the highest Pearson Correlation to CMDQ followed by RULA and REBA. In conclusion, the maintenance workers were found to be exposed to ergonomic risk factors (ERFs) and ergonomics improvement were needed in future.
