BU: Yoga as Effective as Physical Therapy to Reduce Back Pain

Yoga is as effective as physical therapy to treat mild to moderate chronic low back pain (cLBP), including among underserved patients with more severe functional disability and pain, according to a study co-authored by a Boston University School of Public Health (BUSPH) researcher.

The study, in the journal The Annals of Internal Medicine, used a randomized trial of 320 predominantly low-income, racially diverse adults ages 18 to 64 with nonspecific cLBP. Participants received 12 yoga classes, 15 physical therapy visits, or an educational book and newsletters about managing back pain, followed by a 40-week maintenance period with yoga drop-in classes or home practice for the yoga group, and physical therapy booster sessions or home practice for the physical therapy group.

About one-half of participants in both the yoga and physical therapy groups reported reduced pain and disability, compared to about one-fifth of participants in the education group. The yoga and physical therapy participants were about 20 percent less likely to use any pain medication at 12 weeks compared to the education group.

Previous research has already shown yoga is effective for cLBP, the authors write, but its effectiveness compared to physical therapy was unknown. Likewise, little is known about yoga’s effectiveness for minority and low socio-economic status (SES) patients with more severe functional disability and pain. “Despite pain’s disproportionate impact on minority and low SES groups, few cLBP studies and even fewer yoga and PT trials have targeted these populations,” the authors write.

“Finding that yoga is as effective as physical therapy for chronic low back pain is important in that yoga can be performed long-term at home or in group settings where there is social support, it has additional mental health benefits, and may be a cost effective alternative,” said Dr. Janice Weinberg, professor of biostatistics at BUSPH, who was a co-author on the study.
