The medical manufacturing industry is currently one of the sectors with great potential growth in Malaysia, which offers numerous job opportunities to local and foreign workers. The growing proportion of workers in this industry means that a large number of workers are potentially exposed to ergonomic risk factors at the workplace, which may consequently affect their health. Thus, this study was carried out is to investigate the ergonomic risk factors and the prevalence of musculoskeletal disorders among male workers in a medical manufacturing company in northern Malaysia. Eight industrial workers (n = 8) were recruited from two Plastic Technology (PT) departments to participate in this study. Observations were made by recording the participants performing two tasks (manual lifting of containers and bags of chemicals) using a video camera at the PT1 and PT3 departments. The participants’ personal information and their job-related characteristics were first collected using a demographic questionnaire. Next, the Cornell Musculoskeletal and Hand Discomfort Questionnaire (CMDQ) was used to evaluate the prevalence of musculoskeletal disorders among workers while Manual Handling Assessment Charts (MAC) were used to assess the most common risk factors during the lifting operations. The results showed that the highest prevalence of musculoskeletal disorders among the male workers at the medical manufacturing company was at the lower back (83.17%), upper back (4.38%), right shoulder (3.49%), and left shoulder (3.49%). Based on the results of the MAC, 100% of the participants were at high risk of injury from postures in the vertical lift zones, torso twisting, and sideways bending. In addition, 87.5 and 62.5% of the participants were at high risk of injury based on their hand distance from the lower back and grip on the load, respectively. The results of this study can serve as a guideline to implement interventional ergonomics programmes at the workplace and improve the musculoskeletal health of workers in the medical manufacturing industry in Malaysia.

BACKGROUND: Work-related musculoskeletal disorders are the most common occupational health hazards. In the flour production industry, the fast pace of work, high frequency of repetitive movements, manual handling of loads, and awkward postures put a lot of pressure on the worker’s body. OBJECTIVE: Given the high exposure of the workers of the flour production industry to ergonomic risk factors, this study aimed to reduce the rate of musculoskeletal disorders among a group of flour factory workers through ergonomic interventions. MATERIALS AND METHODS: This interventional study was performed using the census method on the eligible workers of a flour factory. An ergonomic intervention program was planned and implemented with the goal of reducing musculoskeletal disorders. The effectiveness of the program was evaluated by measuring the prevalence of musculoskeletal disorders before and six months after the interventions. RESULTS: Before the intervention, musculoskeletal disorders were most prevalent in the lower back, arms, shoulders, legs, thighs, knees, neck and wrists, respectively. Evaluation of the prevalence of musculoskeletal disorders after the intervention showed the positive effect of the ergonomic intervention program on musculoskeletal disorders in the neck, shoulders, lower back, thighs, knees, and legs (P < 0.05). CONCLUSION: Engineering and management interventions implemented in this study led to a significant reduction in the level of ergonomic risk factors and a reduced rate of musculoskeletal disorders among workers of different units in the flour factory.

Introduction: The condition of work in handloom weaving industries cause musculoskeletal (MSDS) disorders which are the most prevailing professional problem among weavers. The aim of this research was to determine ergonomic risk factors in the occurrence of musculoskeletal disorders. Method: The present study was done through descriptive cross-section method to assess the risk factors of work-related musculoskeletal disorders of the weavers. Our data collection tools were: demographic questionnaire, job Nordic questionnaire and body map prevalence of musculoskeletal disorders to decide the rate of symptoms. Then, we took film from handloom weavers while wearing to know the condition of their bodies. After reviewing the films, the posture marks was assigned to each duty using the Ergo Intelligence software. At the end, data were analyzed via one-way ANOVA and T-test using SPSS ver.20. Results: The results showed that the most frequent incidence of pain in different organs of the body during last year belonged to neck and shoulder. The average OCRA was 3.65.This indicated that most of the handloom weavers (64.4%) are at high risk. Conclusion: According to the re According to the results of OCRA indices, weavers are at high risk for musculoskeletal injuries, indicating their poor working environment and working conditions, indicating the need for corrective actions.

The objective of the study is to identify the symptoms ofmusculoskeletal disorder (MSD) and ergonomic risks on manual handling task at a metal stamping company. Data were collected using Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and the Rapid Upper Limb Assessment (RULA). The results revealed that there were significant relationships between self-reported pain and RULA posture scores on the trunk and neck regions with reference to MSD symptoms. Further, the results of RULA score also indicated high risk posture level on the task being investigated.
