• It is estimated that from 80% to 90% of people in the United States will experience at least one episode of lower back pain in their lifetime.
• Most cases of acute back pain are self-limiting, and when treated in accordance with evidence-based guidelines, more than 70% of acute patients become pain free.
• Between 70% and 90% of those who have one episode will have at least one recurrence, and of those, about 33% have lower back pain more than half the days of the year.
• The lifetime U.S. prevalence of chronic lower back pain (>3 months duration) is 10%-20%.
• Approximately 5% of patients with chronic lower back pain have severe, disabling pain that incurs significant expense and can take a serious psychosocial toll on patients and their families.
