The book "Investigation of Postures and Prevalence of Musculoskeletal Disorders" by Taiwo Samuel provides a comprehensive analysis of the impact of body postures on the prevalence of musculoskeletal disorders (MSDs) in the context of gari frying methods. It demonstrates that existing manual methods not only hinder productivity but also pose health risks. By examining common working positions and their physical strains, it becomes clear that simple, cost-effective adjustments to work methods can help reduce MSD risks. The book relies on various assessment methods to determine the prevalence of MSDs and offers valuable insights into the specific complaints associated with different body postures. The findings emphasize the need to implement ergonomic practices in the gari frying industry to protect workers' health while also expanding income opportunities in rural and informal sectors.
