New research discovers the practice of mindfulness meditation can provide individuals with chronic low back pain a non-drug alternative to managing their discomfort.
The finding is significant as chronic low back pain is on the rise in the United States and is the second most common cause of disability in US adults.
Low back pain is common with more than 80 percent of the population experiencing back pain at some time in their life. For some the pain becomes chronic — a condition that surgery usually does not improve — leaving pharmaceutical intervention and perhaps physical therapy as the main source for pain relief.
Meditation long has been practiced as a way to calm the mind, and possibly achieve enlightenment. Now, the new study shows that quieting the mind may be a non-drug alternative to help decrease chronic low back pain. Investigators from the Group Health Research Institute explored alternatives to pain medication in treating chronic low back pain.
Researchers compared a specific kind of meditation called mindfulness-based stress reduction (MBSR) along with cognitive behavioral therapy, a kind of talk therapy, to see if these interventions might alleviate pain.
The results were encouraging, said study leader Daniel Cherkin, Ph.D., a senior investigator at Group Health Research Institute.
“We’re constantly looking for new and innovative ways to help our patients,” Cherkin said.
“The research suggests that training the brain to respond differently to pain signals may be more effective — and last longer — than traditional physical therapy and medication.”
Results from the study have been published in The Journal of the American Medical Association (JAMA).
MBSR is becoming increasingly popular and available in the United States, say the authors. It involves training in observing, acknowledging, and accepting thoughts and feelings including pain. The training also includes some easy yoga poses to help participants become more aware of their bodies.
“We are excited about these results, because chronic low back pain is such a common problem and can be disabling and difficult to treat,” Dr. Cherkin said.
The trial enrolled 342 Group Health patients aged 20 to 70. Their low back pain had lasted at least three months and could not be attributed to a specific cause.
The trial participants were randomly assigned to one of three groups. The first two groups received training in eight weekly two-hour group sessions in addition to whatever care they chose to seek independent of the study.
One of these groups received training in MBSR and the other in cognitive behavioral therapy (CBT). The third group received only their usual care.
Compared to the group receiving usual care, participants in both the MBSR and CBT groups were significantly more likely to experience clinically meaningful (at least 30 percent) improvements from baseline in functional limitations and in self-reports of how much back pain bothered them.
The proportion of participants with these improvements was similar, with no significant differences, between the mindfulness and CBT groups at each time point: one, two, and six months — and at one year — after enrolling in the study.
Usual care is whatever patients would be doing for their back pain if they weren’t in the study, including medications and physical therapy — but not mindfulness meditation or cognitive behavioral therapy.
Before this trial, other research had shown mindfulness helped back pain in older adults — but it had never been tested in young or middle-aged adults.
CBT, which was developed to treat depression, also had been previously proven effective for back pain in a variety of age groups. CBT is training to help people reframe how they think about pain so that they can manage it more successfully and change their behaviors, such as lack of exercise, that contribute to continued pain.
“We are not saying ‘It’s all in your mind,'” Dr. Cherkin said.
“Rather, as recent brain research has shown, the mind and the body are intimately intertwined, including in how they sense and respond to pain. Both mindfulness and CBT involve the brain as well as the body. We found that these approaches were as helpful for people with chronic back pain as are other effective treatments for back pain.”
They also had longer-lasting benefits and were safer than many other treatment options.
“Our findings are important because they add to the growing evidence that pain and other forms of suffering involve the mind as well as the body,” he added.
“Greater understanding and acceptance of the mind-body connection will provide patients and clinicians with new opportunities for improving the lives of persons with chronic back pain and other challenging conditions that are not always effectively managed with physical treatments alone.”
Going forward, researchers want to see if the pain relief is maintained.
“We want to see whether the effects of mindfulness and CBT persist for more than a year,” Dr. Cherkin said. “And we want to learn whether mindfulness and CBT affect people through the same or different processes.”
That is, do the benefits of mindfulness training result from increased mindfulness and acceptance of pain? Whereas, do the benefits of CBT result from changes in pain beliefs and more effective use of pain coping strategies? Or, do the techniques work by the same process?
