The purpose of this study is to determine if yoga is an effective intervention in treating individuals with chronic low back pain (LBP).

Chronic LBP is a major public health problem associated with functional and psychological disability. Conservative interventions are often prescribed to people suffering from chronic LBP, but alternative interventions like yoga are not well researched. The regulator practice of yoga may improve pain, disability or quality of life in people with chronic LBP.
