Yoga May Help Ease Chronic Low-Back Pain, but Benefits Are Modest, Study Finds

Article excerpt

Yoga may benefit some people with chronic low-back pain, although any improvement in either function or pain relief is likely to be modest, according to a new Cochrane review.

The authors of the review also say they were unable to determine whether yoga is more effective than other forms of exercise at relieving low-back pain, due to a lack of research comparing the two approaches.

Yes, these findings are rather underwhelming. But any treatment that offers even modest help in relieving low-back pain and is generally inexpensive and without negative side effects is welcome news, particularly given how many millions of people suffer bouts of low-back pain each year.

As the Cochrane reviewers point out, their findings will help low- back pain sufferers "make more informed choices about their future treatment options."

The review was published online earlier this month in the Cochrane Database of Systematic Reviews.

A common complaint

Low-back pain is an exceedingly common medical complaint and a leading reason people visit their doctor or call in sick to work. Up to 80 percent of Americans experience significant low-back pain at some point in their lives, and during any three-month period, almost a third of U.S. adults report having at least one day of such pain, according to the Centers for Disease Control and Prevention (CDC).

Although low-back pain is sometimes linked to a specific disease or medical condition, most cases have unknown causes. Treatments for low-back pain typically include over-the-counter medications, physical therapy and, in rare cases, surgery. Research has also shown that cognitive behavioral therapy and mindfulness-based stress reduction can be helpful. A major study published last year concluded that prescription pain medications (opioids) were generally not effective at treating low-back pain.

Many people recover from low-back pain within a few days or weeks, no matter what treatment is used. But often the pain lasts much longer, leading to a diagnosis of non-specific chronic low- back pain (pain that lasts more than three months and for which there is no obvious cause). Such pain can be debilitating.

A meta-analysis

The new Cochrane review is a meta-analysis. Its authors pooled data collected from 12 randomized controlled trials (considered the "gold standard" for measuring the effects of treatments on humans) that had compared the effectiveness of yoga with other interventions for easing low-back pain. These studies, which were conducted in the United States, India and the United Kingdom, involved 1,080 participants who were mostly between the ages of 34 and 48.

The comparison interventions included non-yoga forms of back- focused exercise, no exercise, and educational programs (such as booklets and/or lectures) that taught self-care. Some of the studies involved more than one non-yoga approach.

The type of yoga used in the studies varied, but the most common was a form of Hatha yoga known as Iyengar. …
