Low-back pain
Low-back pain is a common disorder involving the muscles, nerves and bones of the back. Pain can vary from a dull constant ache to a sudden sharp feeling. Low-back pain is usually classified by duration as acute (pain lasting less than six weeks), sub-chronic (six to 12 weeks) or chronic (more than 12 weeks). IWH research looks at the occupational risk factors for back pain, how to treat and manage it, and prognostic factors related to recovery and return to work.

Persistent pain: its role in work absence, health, and employment after a disabling work-related injury
Among working-aged adults, one of every six injuries that need medical attention are caused by work exposures, with over a third of these injuries leading to periods of work absence or disability. Chronic or persistent pain may occur after an injury. It is currently unclear how many workers experience persistent pain and how it impacts worker health and function, return to work and disability benefit expenditures. In this presentation, Dr. Kathleen Dobson shares findings from a study of Ontario workers experiencing a work-related injury or illness focusing on the prevalence of persistent pain, and its association with return-to-work outcomes.
