Worker-Centered Ergonomics: A Narrative Review of Human Factors Engineering and Workplace Interventions
Keywords:
Ergonomic Interventions, Human Factors Engineering, Musculoskeletal Disorders, Participatory Ergonomics, Workplace Redesign, Occupational Health, Exoskeleton TechnologyAbstract
Ergonomic interventions and human factors engineering are essential components of occupational health strategies aimed at reducing musculoskeletal disorders and improving worker productivity. This narrative review explores recent advancements and challenges in implementing ergonomic practices, particularly within manufacturing, construction, and healthcare sectors. Literature was systematically sourced from major databases including PubMed, Scopus, and Web of Science, using keyword-based search strategies and strict inclusion criteria focused on real-world applications. Findings reveal that technologies such as glove-based exoskeletons and sit-stand workstations significantly reduce physical strain and enhance user comfort. Active rest programs and workplace redesigns contribute to improved metabolic health, reduced sedentary behavior, and greater psychological well-being. Additionally, participatory ergonomics and behavior-based training were shown to increase intervention acceptance and organizational compliance. However, widespread implementation is limited by systemic barriers such as cultural resistance, financial constraints, and lack of institutional support. The study recommends a multifaceted, evidence-based approach integrating technology, education, and participatory design to optimize ergonomic outcomes. Long-term evaluation and inclusive policy development are also emphasized to ensure sustainability. These findings reinforce the need for collaborative, adaptive strategies that prioritize worker-centered design to build safer, healthier workplaces.
