According to the National Institute of Neurological Disorders and Stroke, "Americans spend at least $50 billion each year on low back pain, the most common cause of job-related disability and a leading contributor to missed work." It is second only to the most common neurological condition, the headache. In addition, it's the second most popular reason for a doctor visit, led only by upper-respiratory infections.

Many of us have heard about the benefits of yoga for back pain, and a new extensive study, much larger than than those previously conducted, affirms that yoga can aid in alleviating back pain. Read on for the story from Shari Roan at the Los Angeles Times...

"Chronic back pain is difficult to treat and causes loads of misery. But something as simple as twice-weekly yoga appears to relieve pain and improve mood in people with the condition.

"The study, published in this month's issue of the journal Spine, was a three-year, $400,000 research project funded by National Institutes of Health. Researchers assigned 90 people with chronic low back pain to a yoga group or a control group that received standard medical care.

"Those in the yoga group participated in 24 weeks of biweekly yoga classes designed for people with chronic lower-back pain. Six months after the study ended, those in the yoga group reported significantly more improvements in pain and functionality compared with subjects in the other group. In addition, depression was much lower in the yoga subjects. The use of pain medication was reduced, but that reduction was similar in both groups.

"'The yoga group had less pain, less functional disability and less depression compared with the control group,' Kimberly Williams, the lead investigator, from West Virginia University, said in a news release. 'Proponents of yoga have long described its benefits in reducing back pain. But not everyone was convinced. This is a much bigger, much more rigorous evaluation than had been done before.'

"The classes were taught by an instructor certified in Iyengar yoga, a type that emphasizes posture."
