Stretching and Yoga Effectively Treat Chronic Lower Back Pain :

Chronic low back pain is a common problem lacking highly effective treatment options. Small trials suggest that yoga may have benefits for this condition. The trial was designed to determine whether yoga is more effective than conventional stretching exercises or a self-care book for primary care patients with chronic low back pain.

Chronic lower back pain sufferers observed nearly the same improvement after taking yoga classes taught by highly trained teachers as they did from stretching classes.The findings of this clinical trial have been published in the October 24 issue of the Archives on Internal Medicine, a journal of the American Medical Association.

We found yoga classes more effective than a self-care book – but no more effective than stretching classes,” said lead study author Karen Sherman, a senior investigator at Group Health Research Institute in Seattle. “We expected back pain to ease more with yoga than with stretching, so our findings surprised us,” she said.

A total of 228 adults with chronic low back pain were randomized to 12 weekly classes of yoga (92 patients) or conventional stretching
exercises (91 patients) or a self-care book (45 patients). Back-related functional status (modified Roland Disability Questionnaire, a 23-point scale) and bothersomeness of pain (an 11-point numerical scale) at 12 weeks were the primary outcomes. Outcomes were assessed at baseline, 6, 12, and 26 weeks by interviewers unaware of treatment group.

After adjustment for baseline values, 12-week outcomes for the yoga group were superior to those for the self-care group (mean difference for function, –2.5 [95% CI, –3.7 to –1.3]; P < .001; mean difference for symptoms, –1.1 [95% CI, –1.7 to –0.4]; P < .001). At 26 weeks, function for the yoga group remained superior (mean difference, –1.8 [95% CI, –3.1 to –0.5]; P < .001). Yoga was not superior to conventional stretching exercises at any time point.

In the year 2005 these researchers conducted a smaller trial in 2005 based on a randomized sample of 101 adults. That study suggested yoga was the best remedy for back pain because those who practiced it used fewer pain relievers and had better back function.

The yoga was a type known as viniyoga, which features poses adapted for the individual condition of those in the class, breathing exercises and a deep relaxation period. Classes were taught by instructors with more than 500 hours of training. The stretch classes were taught by licensed physical therapists with teaching experience and two hours of training in techniques that focused on the trunk, legs, hamstrings and hips. Some strengthening exercises were also included.The third group was given a self-care book called “The Back Pain Helpbook” to read for tips on alleviating pain.

The stretching group reported superior function at six, 12 and 26 weeks. At no point in the follow-up analysis was there a statistically meaningful difference between the stretching and yoga groups.

Yoga classes were more effective than a self-care book, but not more effective than stretching classes, in improving function and reducing symptoms due to chronic low back pain, with benefits lasting at least several months.”The most straightforward interpretation of our findings would be that yoga’s benefits on back function and symptoms were largely physical, due to the stretching and strengthening of muscles,” Sherman said.

“Our results suggest that both yoga and stretching can be good, safe options for people who are willing to try physical activity to relieve their moderate low back pain,” she said. “But it’s important for the classes to be therapeutically oriented, geared for beginners, and taught by instructors who can modify postures for participants’ individual physical limitations.
