The Definition of Ergonomics
Ergonomics is the scientific discipline concerned with designing tasks, tools, and work environments to fit the physical capabilities and limitations of the worker.

Ergonomics is the scientific discipline concerned with designing tasks, tools, and work environments to fit the physical capabilities and limitations of the worker, rather than requiring the worker to adapt to poorly designed conditions. In a workplace safety context, ergonomics focuses on reducing risk factors such as repetitive motion, awkward postures, excessive force, and prolonged static positions that can contribute to musculoskeletal disorders over time. Effective ergonomic design can involve adjusting workstation heights, providing supportive seating, redesigning tools to reduce grip strain, or reorganizing tasks to minimize repetitive strain, all aimed at reducing cumulative stress on the body during work activities.
Warehouse employees who repeatedly bend and twist to lift boxes from low shelving begin reporting lower back pain; after an ergonomic assessment, the facility raises shelving heights and introduces adjustable-height lift tables, significantly reducing awkward postures and reported discomfort among the affected workers.
Signs often include workers reporting recurring discomfort or pain in the back, shoulders, wrists, or neck, frequent adjustment of body position to complete a task, and a higher-than-expected rate of musculoskeletal complaints associated with a specific job or workstation.
Poor ergonomics is commonly linked to musculoskeletal disorders such as carpal tunnel syndrome, tendinitis, lower back strain, and chronic joint pain, which typically develop gradually from repeated strain rather than a single traumatic event.
Employers can improve ergonomics by conducting workstation assessments, providing adjustable furniture and equipment, rotating employees through varied tasks to reduce repetitive strain, and training workers on proper lifting and posture techniques.
