Yoga Interventions for the Prevention, Treatment, and Rehabilitation of Medical Conditions
This guide provides a brief overview of this topic and a curated list of the most important relevant resources and those frequently cited, referenced, or recommended by current scholars and experts in the field.
Overview
Yoga refers to a system of physical postures, breath control, and often meditation practices originally derived from a Hindu spiritual and philosophical tradition. More and more people are reporting health benefits from practicing yoga, and in recent years the use of yoga as an intervention for cardiovascular, respiratory, organ, immune, and autoimmune health in general and women’s and elderly health in particular and for the prevention, treatment, and rehabilitation of particular medical conditions has greatly increased. According to surveys, 14.3% of U.S. adults reported practicing yoga in 2017, up from 9.5% in 2012, a year in which 94% of U.S. yoga practitioners reported engaging in the practice for wellness-related reasons and 18% reported doing so to treat specific health conditions with back pain, stress, and arthritis being the most common conditions cited.[1]
More people are practicing yoga, more people are reporting health benefits, and research is rapidly expanding to explore popular claims. A marked increase in yoga intervention studies began in 2000, with steady growth since 2007, and over 200 new research articles published annually since 2011.[2] Significant findings from these studies suggest that practicing yoga correlates with decreases in stress and unhealthy inflammation; increases in strength, flexibility, and body awareness; and more balanced hormone and cortisol levels and that yoga is a safe, accessible, and valuable complementary health treatment.
The diversity in yoga styles, research methods, and treatment plans, however, makes it difficult to draw strong conclusions about the efficacy of yoga interventions. Many studies have a low number of participants and no control group, and many do not compare yoga to similar interventions, such as exercise or meditation. For example, the first ever randomized trial on yoga, published in 1975, found that yoga was more effective than relaxation in reducing high blood pressure, but the trial included a mere 34 participants, all with high blood pressure.[3] Many subsequent studies have had similar limitations in sample size, participant selection, and length.
Of the studies that have included control or comparison groups, few have protected against bias by blinding participants to the intervention. Other problems with yoga intervention research historically include: a lack of long-term studies; few studies on the adverse effects of practicing yoga; a predominant focus on adults (white women comprise the majority of study participants); and a limited focus on common medical concerns, including back pain, breast cancer, and multiple sclerosis.
Yoga is complex and may include many components, such as poses, breathing exercises, meditation, relaxation techniques, chanting, visualization, and more. Yet many studies still fail to report on or adequately account for these variables, making them impossible to duplicate. For studies to be relevant and reliable, researchers must precisely explain the type of yoga used, the dose and delivery, the class sequences and modifications, the selection of instructors, the setting, the assessments, the measurement of intervention fidelity, etc.
In the United States, yoga research falls under the purview of the National Center for Complementary and Integrative Health—the U.S. government’s lead agency for scientific research outside of conventional medicine (founded in 1991 as the Office of Alternative Medicine). This agency receives frequent criticism for funding studies with little supporting scientific evidence and for insufficient discovery of new medical research or treatment.
Despite these various issues, yoga research has continued to grow and become more robust over time. For example, in 2005, the seminal study on yoga for low back pain was published. This well-regarded randomized, controlled trial with thorough reporting included 101 adults with chronic low back pain divided into a yoga group, an exercise group, and a self-care book group. The experience lasted for 12 weeks, with a follow-up assessment at 26 weeks.[4] Positive results for the yoga intervention group spurred many more studies on yoga for low back pain.
Researchers have begun to consider the effects of yoga interventions on other populations, such as on children practicing yoga in schools, and with respect to other concerns, such as joint disorders, organ cancers, and nervous system conditions. They’re also beginning to examine the precise physiological mechanisms underlying yoga’s effects on health, such as the impact practicing yoga has on inflammation and the autonomic nervous system.
Much of the research on yoga interventions continues to come from the United States and India. Increasingly, however, yoga research is being done around the world. For example, in Germany, the Department of Internal and Integrative Medicine at the University of Duisburg-Essen was established in 2004; currently under the supervision of Gustav Dobos, M.D., Jost Langhorst M.D., and Holger Cramer, the department is known for its scholarly productivity. In Australia, the Australian Research Centre in Complementary and Integrative Medicine, established in 2012, has quickly become a leading critical public health and health services research center focusing on traditional, complementary, and integrative health care.
In the future, research on yoga interventions is likely to continue to expand and improve in coverage, methodology, and reporting. For example, some yoga intervention researchers are now advocating for the Consolidated Standards of Reporting Trials (CONSORT) guidelines (first developed in 1996 to improve research quality and since refined and adopted by established journals) to be expanded to make them more relevant to complementary and alternative medicine and to add guidelines on developing and reporting study protocols. More open communication and collaboration among individuals, doctors, and yoga instructors will also assist in improving the design and effectiveness of yoga interventions.

Journal of Psychiatric Practice, 16(1), 22-23. https://doi.org/10.1097/01.pra.0000367775.88388.96
This article reviews evidence and mechanisms for the impact of yoga on depression from eight clinical trials, and outlines future research directions. Results from these trials are positive, but findings are preliminary. Yoga has “active ingredients” of other successful treatments for depression and may also have biological, psychological, and behavioral mechanisms that explain its effect.

In a randomized study of 90 participants with chronic low back pain, half of the participants practiced a special biweekly Iyengar yoga class for 24 weeks, for significantly greater reductions in functional disability, pain intensity, and depression than the participants in the standard care control group, at the 12 week and 24 week assessments.
