Yoga has become a familiar part of the health and fitness scene. Nearly 32 million people currently practice yoga. Another 18 million say they plan to try it within the year. Although many people turn to yoga to ease stress and improve overall health, a growing number have specific medical aims and are following the recommendations of their doctors.
According to a study, yoga therapy can reduce pain and improve function in people with chronic low back pain. Chronic low back pain, which usually lasts more than three months, is notoriously difficult to treat. Not surprisingly, it drives many sufferers to turn to alternative and complementary therapies in search of relief. The study is the second of two randomized trials to test a specific form of yoga called Iyengar (pronounced eye-en-gar) yoga, which is based on the teachings of B.K.S. Iyengar, one of the world’s most well-known living yoga teachers.
Most yoga taught and practiced is hatha yoga, which combines classic poses (asanas), controlled breathing, and deep relaxation or meditation. Iyengar is a type of hatha yoga that uses props such as blankets, blocks, benches, and belts to help people perform the poses to the fullest extent possible even if they lack experience or have physical limitations. The emphasis is on precise physical alignment, with trained teachers adjusting everything from the position of the shoulders to the angle of the toes.
Overall, the researchers found that the yoga group showed not only greater improvements in pain and mobility, but also a larger reduction in depression symptoms. In addition, the benefits were seen immediately after the six-month yoga regimen ended, as well as six months later.
The findings do not mean, though, that every style of yoga is right for back-pain sufferers.
People have to remember that this was a therapeutic Iyengar class. It is recommended that people with lower back pain who are interested in trying Iyengar yoga find a certified teacher with the experience to help them adjust the poses to their needs. That means talking with the teacher before starting a class, and keeping him or her posted on how the back problem is faring.
The subjects who participated in the study had been suffering from lower back pain for more than three months. About half took twice-weekly yoga classes for 24 weeks, while the rest were put on a 6-month waiting list while staying with usual care, such as pain medications.
After 24 weeks, the yoga group reported greater improvements in pain and disability, on average, than the comparison group. And while none of the study participants had major depression, the yoga group’s scores on a standard measure of depression symptoms improved to a greater degree than the comparison group’s.
When the researchers evaluated the patients six months later, they found that the yoga group was still faring better, on average.
