Low back Pain

About 80% adults experience low back pain at some point in their lifetimes. It is the most common cause of job-related disability and a leading contributor to missed work days. In a large survey, more than 25% adults reported experiencing low back pain during the past 3 months.

Most low back pain is acute, or short term, and lasts a few days to a few weeks.

Subacute low back pain is defined as pain that lasts between 4 and 12 weeks.

Chronic back pain is defined as pain that persists for 12 weeks or longer, even after an initial injury or underlying cause of acute low back pain has been treated. About 20 percent of people affected by acute low back pain develop chronic low back pain with persistent symptoms at one year.
