Ergonomic intervention to reduce musculoskeletal disorders among flour factory workers

Abstract

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.

Effectiveness of training program in manual material handling

“…Due to the role of fatigue in reducing the quality of work and human error and the subsequent occurrence of MSDs, effective training in this field can eventually improve the health of workers. [ 5 24 ]…”

“…Education is one of the most important factors affecting safety and health and thus health promotion, which has been widely studied by other researchers. [ 24 ] The health education approach actually starts from the ground up and advises people to change their behaviour and move in a specific direction that is beneficial to their health. [ 25 ] Health education for workers is in the field of work fatigue, proportion of work environment components with workers, ergonomic risk factors and the correct way of MMH with the aim of preventing MSDs and safe load carrying, which ultimately leads to improved health among workers.…”

Musculoskeletal Disorders: Industrial Insights and Ergonomic Interventions

“…In the domain of food processing, flour creation holds significance, yet it confronts issues tied to laborer health, notably musculoskeletal disorders (MSDs). Hemati et al (2020) undertook an exploration into these concerns and launched an ergonomically-designed alleviation scheme tailored for the flour creation environment. The scheme didn't limit its focus to just the tactile dimensions; it adeptly amalgamated technical remedies with administrative blueprints for a comprehensive alleviation strategy.…”

Prevalence of Upper Limb Dysfunction in Fashion Designer Students Using Fades Chairs

“…The Fades chair is an ergonomic seating option specifically designed to mitigate the risks associated with prolonged sitting and repetitive hand movements. With its adjustable features and ergonomic design, the Fades chair aims to promote optimal posture, reduce strain on the upper limbs, and enhance overall comfort during extended periods of work (6).…”
