In a study funded by the NIH and reported in the Journal Spine in September 2009, researchers at West Virginia University showed yoga helped people with chronic low back pain.
90 total patients were split into two groups. One group participated in 24 weeks of biweekly yoga classes designed for CLBP (Chronic low back pain), the other group received standard medical care.
The study concluded "Yoga improves functional disability, pain intensity, and depression in adults with CLBP. There was also a clinically important trend for the yoga group to reduce their pain medication usage compared to the control group."

The reports authors stated ""Despite the fact that significant improvements at 12 weeks were found in the participants adherent to the study, we believe that a 24-week period of yoga practice for [chronic lower back pain] is superior since this time period can better prepare participants to sustain the benefits by improving posture, helping to retrain the musculoskeletal system, and building the skills needed to decrease the rate of relapse,""
