Ergonomic Assessment of Manual Handling Techniques
Summary
Ergonomic assessment of manual handling techniques evaluates the physical demands and health risks associated with lifting, carrying, pushing and pulling tasks. Traditional methods relied on static strength predictions and observational checklists, but contemporary practice integrates wearable sensors, digital human modelling and biomechanical simulation to capture dynamic postures, joint loads and muscle activity. Subjective measures of perceived exertion and fatigue complement objective data, offering a holistic view of worker effort. This research underpins design of handling aids, workspace layouts and training interventions, and informs regulatory guidance on safe load limits. Its global significance spans manufacturing, healthcare and logistics, where optimising manual tasks reduces incidence of musculoskeletal disorders, enhances productivity and supports inclusive design for workers of varying anthropometry.
