The document discusses using the Lumbar Motion Monitor to assess risk of occupational low back disorders. It notes that low back disorders affect most people during their working careers, are a primary cause of activity limitation for those under 45, and cost society up to $100 billion annually. The Lumbar Motion Monitor measures biomechanical factors like lift rate, twisting velocity, moments, and ranges of motion that, along with psychosocial factors like job dissatisfaction and support, can help identify risks of low back disorders for specific jobs and employees.
