Development Of Lumbar Support Device Using Malaysian Anthropometry Database And Its Physical And Physiological Effects
description Nowadays, competitions between industries benefit the global economically. However, the workers were working repetitively in awkward posture and heavy lifting could potentially increase the cause of lower back pain (LBP) and musculoskeletal disorder (MSD). Intervention using the lumbar support system is among the methods that could solve this issue and improve the safety and comfort of the workers. Therefore, this research aims to focus on the development of the lumbar support device for industrial workers using the Malaysian anthropometric data. Currently, lumbar support is one of the tool examples which have been used to reduce the LBP issue in the industry, but how far this support device can effective to reduce this issue. Thus, the functionality of surface electromyography (sEMG) is used to detect muscle function or muscles activity through electrical stimulation. Consequently, the analysis of muscle of workers through sEMG was proposed to detect the functionality of an application of current lumbar support. The data were collected through surveys among 45 layup workers in the aerospace composite manufacturing industry. The qualitative and quantitative data were collected. From the data that were sorted, the respondents were validated using sEMG and heart rate monitor to detect the biomechanical factors that contribute to fatigue during working. Beforehand, the anthropometric data was developed in the early designing stage. The design of new lumbar support was followed process of anthropometry data collection, design, material selection and validation. The manipulated variables are the workers that without, with current and new lumbar support device. The sEMG data can measure and validate the muscles activity values during work based on these three variables. From this study, the level of pain faced by workers in moderate and very pain at lower back muscle was 59% and 17% of workers. In biomechanical factors of sEMG and heart rate (HR) have a significant effect on HR3 and HR4 at the end of the working day. The parameter that used in designing new lumbar support device were biacromial breath, neck height, chest height, waist height, trochanterion height, chest circumference, waist circumference, buttock circumference, and scye circumference. The result of this work is producing the comparison data to design the new lumbar support device, the reducing of amplitude value was 60.57% compared to workers that not wearing this device while 56.33% compared to workers that wearing current lumbar support device. This device resulted to reduce the LBP problem in industries and methods of this study contributed to society which are anthropometric database and muscle activities .
