Yoga Better than Injections for Low Back Pain

by Baxter

A July 18th New York Times blog post entitled Alternatives for Back Pain Relief surprised me when it proclaimed that a modern and widely used treatment method for low back pain is no longer considered effective, especially for chronic or long-standing low back pain. That treatment is the use of injections into the areas of pain. The injections usually contain the inflammation-decreasing drug cortisone, but can also have ingredients like morphine, ibuprofen and vitamin B12 in the mix. Over the years I have had many patients come to me with low back pain, and from their reports, the effectiveness of the injections never seemed particularly strong. For some patients with new acute low back pain, who experienced more serious signs and symptoms, like radiating pain to the leg or actual weakness, the injections more often seemed to provide some temporary pain relief.

However, several new studies have revealed that, when looking back at those patients treated with injections, the injections were not significantly more effective than no treatment at all. And one study indicated that those who did not get injections for a pinched nerve in the lower back fared better down the road than the patients who received an injection course.  In the commentary published in a recent issue of JAMA:

“Based on the available data, the JAMA authors conclude, doctors “should not” recommend injection therapy to their patients with chronic low back pain.” 

That may be a hard pill for some doctors to swallow, as there has been a steady increase in the use of injections for low back pain, mainly because it is relatively inexpensive, can be done as an outpatient in the office, has fewer risks compared to surgery, and makes the docs some bling. The possible one positive use of injections is that is does often provide some temporary relief of low back pain symptoms.

The New York Times post then went on to reference a recent systematic review of yoga for low back pain that we reported on here early this year. This study looked back at all of the best designed studies on the subject and concluded that there was “strong evidence of short term effectiveness of yoga for low back pain and moderate evidence of long-term effectiveness of yoga.”

But although the New York Times post mentions the clear benefit of yoga for short-term back pain, it does not emphasize the second claim that the study discovered: moderate evidence for yoga's help over the long term. I took another look at the study itself, and discovered an important caveat: the authors would only recommend Viniyoga style practice for long-term benefits, as the other yoga methods studied did not demonstrate the same benefits. As they state:

"The American Pain Society's guidelines recommend that clinicians consider offering yoga to patients with chronic LBP (lower back pain). However, this recommendation is limited to Viniyoga-style yoga as the net benefits for other yoga styles could not be estimated."

Now, I love Viniyoga and integrate its methods into my own practice and teachings, along with the wisdom of the Iyengar method and some other modern yoga styles I’ve learned over the years as well. But I suspect that some of the alignment-strong styles, like the Iyengar method, will prove to be helpful in the long run as well, but we will need better studies to bear that out. That said, for those who are not familiar with Viniyoga (a term coined by American yoga teacher Gary Kraftsow for the yoga he learned from T. Krishnamacharya and TKV Desikachar) I would recommend to you two books to learn more:

1. The Heart of Yoga by TKV Desikachar
2. Yoga for Wellness by Gary Kraftsow

For now, this is all good news for those of us dedicated to our practice. As one of my students said to me just this morning after class, it's his regular yoga class that keeps his back in the best shape over time since he first developed low back pain many years ago. I’d love to hear back from our readers about your experiences with yoga for low back pain, so send me your story!

And don’t forget, my live webinar on Yoga for Healthy Digestion starts today, Tuesday July 23, 2013 on Yoga U online! Click here to learn more about it and sign up to join me Tuesday and Thursday from  8:30 EST (5:30 PST).

Unclear on the Concept: Yoga as a Treatment

by Nina

Wet Handle Bars by Melina Meza

“A comprehensive review published in May in The Clinical Journal of Pain finds that there is “strong evidence for short-term effectiveness” of yoga against back pain, although whether the benefits last beyond a year is less certain.” — Gretchen Reynolds, NY Times Sunday Magazine

In this Sunday’s New York Times Magazine, there was a short article called “Spinal Trap,”
about alternatives for treating back pain. The subtitle was “How do you solve back pain? Don’t ask your doctor.” We’ve already heard from Baxter on this topic, when he confessed that he had little to offer his patients when he himself was a family doctor (see For the Young and Old: Back Care). And you’ll be hearing from him soon about the comprehensive review mentioned in the quote above.

For now, I’d just like to rant a bit about the second half of the sentence:

“strong evidence for short-term effectiveness” of yoga against back pain, although whether the benefits last beyond a year is less certain

At first, I was just confused. What does she mean it is less certain whether the benefits last beyond a year or not. If you’re doing yoga for your back pain and it helps your back pain, why wouldn’t it continue to help your back pain for as long as you kept practicing? But Brad pointed out to me the underlying confusion in this statement. He said, “She’s thinking about yoga like physical therapy. In other words, it’s like a “treatment” you get from the doctor, something you’d do for a couple of months to “cure” your back pain, but then when you felt better you’d stop the treatment. And then maybe the pain would come back eventually.”

Ah, so that's what she meant. But how completely unclear on the concept is that? Naturally, if something in your life is causing you back pain, whether it’s your posture at your desk or in your car, standing all day at your job, too much gardening, lifting your children, lack of exercise in general, stiffness in certain areas of your body, lack of strength in certain areas of your body, you can’t just go back to your old way of life and expect the results of a short session of yoga classes to see you through the rest of your life. That would be like thinking you could do a few months of weight training to get stronger, and then expecting that would keep you stronger for years to come.

Brad laughed and said, “Yeah, and it’s not like there’s a “cure” for aging.”

So, yes, we’re afraid that whether you are practicing yoga for back pain or another condition, or just, you know, for healthy aging in general, it’s going to require an ongoing commitment. But it’s free, has no unpleasant side effects, and oh, yeah, it actually works.

Degenerative Disk Disease and Yoga

by Baxter

In my ongoing attempts to stay up on the developing information about yoga, aging and health, I look at other online sources of new information. One such resource is the online site called Yoga U, which sends out a periodic newsletter as well as offering special live interactive webinars on a variety of topics and yoga. (I’ll be doing a webinar for them in May on “Yoga and the Digestive System” so stay tuned!) As I was preparing for my Sunday session at Yoga Journal Conference last week “Yoga for Arthritis,” I came across a piece on Yoga U about a recent study that looked at degenerative disc disease. 

Degenerative disc disease is a process of change to the cushion-like discs found between the vertebrae or spinal bones. It most commonly affects the discs in the neck/cervical region and the lumber/lower back region. There is some ongoing debate on whether the deterioration of the discs is a natural part of the aging process (since it is seen in people without symptoms of back or neck pain in gradually increasing percentages as we age) or whether it is directly related to an abnormal condition of change in the discs. It is really part of the general wear and tear arthritic changes we see in other joints, as the discs represent a unique kind of cushion structure that is similar to the cartilage caps found on the ends of other bones in major joints of movement. But it is different from the regular cartilage in other joints in that it is a larger structure, not adherent to the vertebrae above and below it, as well as having a unique structure that distributes the intense force of gravity that travels down the spine in a specialized way.

Spinal Vertebrae and Discs

Despite our uncertainty as to a direct correlation between the presence of degenerative disc disease and back and neck pain, I have LOTS of patients and students who have both situations present together. So if I knew of something to offer them that could decrease the development of degenerative disc disease, I would be hopeful it would also reduce their chances of pain as well. The study discussed on Yoga U,  which was originally published in the European Health Journal, March 2011, compared the spines of long time yoga teachers, via MRI imaging, to those of a matched group who did not do yoga. Lo and behold, the yoga teachers, who had been teaching for at least 10 years, had significantly less degenerative disc disease.

The study, done in Taiwan, looked at yoga teachers that practiced a gentle and slow form of yoga. I found this quite compelling, since much of the yoga we recommend here at YFHA is somewhat gentle, and we always recommend moving mindfully into and out of poses. Those of our readers who practice similarly could benefit from this style of practice in regards to their spinal health. The researchers matched the yoga teachers and the control group for age, sex, general health and all were non-smokers. (Why non-smokers, you might ask? Smoking is considered a risk factor on its own for increased chance of back pain.) Even though yoga teachers had less degenerative disk disease in all areas of the spine compared to the control group, within the teachers themselves there was less degenerative disk disease in the cervical spine versus the lumbar spine. Finally, the researchers concluded that their results suggest that hatha yoga may have slowed the natural aging process in the discs.

They hypothesized that a combination of factors, such as stretching and positioning of the spine, as well as decreased weight-bearing on the spine while practicing yoga, may allow for more nutrients to diffuse or enter the spinal discs. Whatever the reasons, these are surely encouraging results! However, as always with these initial studies, this early evidence warrants further studies with larger groups of people. In the meantime, I am going to continue with my gentle, slow yoga, with the intention that my discs are benefiting every day. Won’t you join me?
