About
A 12-week randomized controlled trial (RCT) for chronic low back pain in predominantly minority populations comparing yoga classes once/week vs. twice/week. Primary outcomes are pain intensity and measure of disability; secondary outcomes are pain medication use, treatment adherence, and health-related quality of life.
Full description
Chronic low back pain (CLBP) affects 5-10% of U.S. adults annually and costs over $50 billion per year in direct health care expenditures. Individuals from low-income minority backgrounds are disproportionately impacted by CLBP due to disparities in access and treatment. Several recent studies suggest yoga is effective for CLBP. Yoga may also have other relevant benefits for CLBP patients, such as improved mood, stress reduction, and lower cost. However, there are no studies which directly compare different doses of yoga for CLBP. It is unknown if there is a meaningful dose- response effect of yoga for CLBP. If there is a dose/response effect, the magnitude of the effect is unknown. The total dose of a yoga intervention depends upon the duration of total intervention, frequency of yoga classes, duration of each yoga class, and home practice (amount, duration and frequency).
To assess the impact of yoga dose, we propose conducting a Pilot Yoga Dosing Study for 96 adults from Boston Medical Center. The Dosing Study will be a 12-week randomized controlled trial where participants are assigned to either once per week 75-minute yoga classes or twice per week 75 minute yoga classes.
During this 12-week study, there will be three points of data collection (baseline, 6 weeks, 12 weeks). In addition, little is known about the reliability of different forms of survey administration in low back pain trials. For example, it is unknown if telephone administered questionnaires or web-based data collection are reliable compared to the traditional paper- administered questionnaire.Therefore we will compare different methods of survey administration at each time point. The results of this Pilot will inform the design of a larger future comparative effectiveness RCT of yoga, physical therapy, and education for chronic low back pain.
