Analysis of Recommended Weight Limit to Mitigate the Lower Back Pain in Manual Material Handling Task

In this paper Authors have tried to calculate the revised Recommended Weight Limit (RWL) on the basis of revised Load constant (LC), Horizontal Multiplier (HM), Vertical Multiplier (VM) which are calculated according to the collected data from industry. While their average value had been considered in National institute for occupational safety &health (NIOSH) lifting equation. Thought behind this was that person’s age, obesity and height can not be taken constant Authors have applied the new approaches for setting limits of LC, HM, VM for optimizing the value of RWL of workers who work in industry. The approach may probably lead to calculate the safe weight for lifting and lowering in manual material handling task. It is expected that such an approach may be more protective for workers in manual material handling.

Work Related Musculoskeletal Disorders

Background: Mining is an ancient occupation, long recognized as being arduous and liable to injury and disease. The lifecycle of mining consists of exploration, mine development, mine operation, decommissioning and land rehabilitation. Objective: To explore the prevalence characteristics and influence factors related to the development of work related musculoskeletal disorders of underground coalminers in Eastern Coalfield mines. Methods: In a cross-sectional study of 55 coalminers from Saatgram Project, Raniganj, Eastern Coalfields, modified Nordic Questionnaire was performed to assess the musculoskeletal disorders. Logistic regression analysis was performed to analyze the correlation between the occupational factors and their work related musculoskeletal disorders. Results: In this study 36 out of 55 miners (65.45%) complained about the development of musculoskeletal disorders at different body parts. The maximum pain was identified at lower back. The presence of lower back pain was observed among 58.18% of miners. The prevalence of pain in different body sites of the miners increased significantly with their ages. According to the present study, the repetitive operations and awkward postures were the risk factors for the development of work related musculoskeletal disorders in neck, shoulder and upper limbs; moreover, the repetitive operation of moving heavy substances and stooping postures continuously were related significantly – with the development of lower back pain at lower limbs due to the long standing awkward posture. Conclusion: It may be concluded from the above study that Eastern Coalfield miners are suffering from work related musculoskeletal disorders. This condition may be rectified by changing working postures or by implementation of ergonomically designed tools and machineries.DOI: http://dx.doi.org/10.3126/ijosh.v2i2.6596 International Journal of Occupational Safety and Health, Vol 2.

Abstract: Lower Back Pain (NPB) or Low Back Pain (LBP), VAS, Acupuncture Therapy, Healing Effect. Previous studies of acupuncture for low back pain were conducted. In this study, the researcher used a combination of BL 23. BL 40 and BL 23, KI 3. This study is aimed to determine the effectiveness of the combination of BL 23. BL 40 and BL 23, KI 3 for recovery low back pain. This study is done during March until May 2015 at Posyandu Lansia Klodran and Bendo Colomadu Karanganyar. This is a quasy experiment research with pre-test and post-test. Thirty subject studies were divided into two groups were treated combination of BL 23. BL 40 in the first group and BL 23, KI 3 in the second group. This treatment was conducted for 10 times. VAS was done before and after 10th therapy. The data obtained thus were analyzed using the Mann-Whitney test. Twenty-nine out of thirty subjects experienced decrease their VAS only one subject did not show any alteration. The average value of VAS decrease is 3.03. Acupuncture therapy with a combination of BL 23. BL 40 and BL 23, KI 3 has been shown that there are no differences between two groups (p>0.05)

Manual Material Handling (MMH) is a risky activity that causes low back pain and has become a worldwide phenomenon, not only in developed countries, but also occur in developing countries. One effort to reduce the injury caused by MMH is the Reccomended Weight Limit (RWL) equation, published by NIOSH. However, NIOSH equation is more tested and researched in European and America. Therefore, it is necessary adjustment for Indonesia people. In this paper, the author analyze the vertical multiplier factor in NIOSH equation for male workers in Indonesia. Multiplier factor is assessed using three criterias. There are biomechanics, physiology, and psychophysical. The result of this study is form of vertical multiplier equation, i.e VM = 1 - 0.0310083 (68-V) and VM = 1 - 0.00708215 (68-V) for an elevation below the knuckle.
