Evaluating biomechanical risks in manual material handling: an ergonomic intervention approach.
Manual waste handling, common in many underdeveloped regions, often exposes workers to musculoskeletal disorders (MSDs) during material tasks. A study involving 92 workers highlighted the risks associated with the waste scraping and picking tasks, focusing on lower back, knee and neck joints. The study aimed to create improved equipment through iterative design. Three-enhanced cleaning equipment versions emerged, hypothesised to boost worker well-being. Comparative ergonomic assessments revealed significant improvements: 67% lower postural scores, up to 58% reduced spinal forces and a 4% drop-in average working heart rate (HR). Pain frequency decreased by 16.67%, severity by 14.29% and productivity doubled, supported by strong Likert chart acceptability. This study underscores ergonomic interventions' potential in reducing risks linked to traditional cleaning practices.
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
