ABSTRACT Fibromyalgia (FM) is a chronic condition characterized by widespread musculoskeletal pain, fatigue, depression, and hypocortisolism. To date, published studies have not investigated the effects of yoga on cortisol in FM. This pilot study used a time series design to evaluate pain, psychological variables, mindfulness, and cortisol in women with FM before and after a yoga intervention.
Participants (n = 22) were recruited from the community to participate in a 75 minute yoga class twice weekly for 8 weeks. Questionnaires concerning pain (intensity, unpleasantness, quality, sum of local areas of pain, catastrophizing, acceptance, disability), anxiety, depression, and mindfulness were administered pre-, mid- and post-intervention. Salivary cortisol samples were collected three times a day for each of two days, pre- and post-intervention.
Repeated measures analysis of variance (ANOVA) revealed that mean ± standard deviation (SD) scores improved significantly (p < 0.05) from pre- to post-intervention for continuous pain (pre: 5.18 ± 1.72; post: 4.44 ± 2.03), pain catastrophizing (pre: 25.33 ± 14.77; post: 20.40 ± 17.01), pain acceptance (pre: 60.47 ± 23.43; post: 65.50 ± 22.93), and mindfulness (pre: 120.21 ± 21.80; post: 130.63 ± 20.82). Intention-to-treat analysis showed that median AUC for post-intervention cortisol (263.69) was significantly higher (p < 0.05) than median AUC for pre-intervention levels (189.46). Mediation analysis revealed that mid-intervention mindfulness scores significantly (p < 0.05) mediated the relationship between pre- and post-intervention pain catastrophizing scores.
The results suggest that a yoga intervention may reduce pain and catastrophizing, increase acceptance and mindfulness, and alter total cortisol levels in women with FM. The changes in mindfulness and cortisol levels may provide preliminary evidence for mechanisms of a yoga program for women with FM. Future studies should use an RCT design with a larger sample size.

    ABSTRACT: Tai Chi and yoga are complementary therapies which have, during the last few decades, emerged as popular treatments for rheumatologic and musculoskeletal diseases. This review covers the evidence of Tai Chi and yoga in the management of rheumatologic diseases, especially osteoarthritis of the knee, hip and hand, and rheumatoid arthritis. There is evidence that Tai Chi and yoga are safe, and some evidence that they have benefit, leading to reduction of pain and improvement of physical function and quality of life in patients. Recommendations for Tai Chi in knee osteoarthritis have recently been issued by the American College of Rheumatology. To allow broader recommendations for the use of Tai Chi and yoga in rheumatic diseases, there is a need to collect more evidence researched with larger randomised controlled trials.

    ABSTRACT: Osteoarthritis (OA) is a leading cause of pain and disability worldwide. Current treatment guidelines recommend nonpharmacological approaches such as yoga for firstline treatment of OA. Yoga is a promising mind-body practice that includes physical postures, breathing practices, and meditative mental focus. This article presents the current evidence, as well as a proposed conceptual model for future research. Current research on yoga for OA is scant but promising, showing some evidence of reduced pain, sleep disturbance, and disability. The conceptual model described here proposes musculoskeletal effects (strengthening, flexibility, relaxation), reduction of autonomic arousal, and therapeutic cognitive patterns (distraction, mindfulness) as potentially important mechanisms of yoga. This article also describes considerations for patients and health care providers when evaluating the potential usefulness and safety of yoga programs: yoga style, instructor qualifications, and amount of time spent in yoga practice.

    ABSTRACT: Objectives. Yoga is used for a variety of immunological, neuromuscular, psychological, and pain conditions. Recent studies indicate that it may be effective in improving pregnancy, labour, and birth outcomes. The purpose of this paper is to evaluate the existing literature on yoga for pregnancy. Methods. Six databases were searched using the terms "yoga AND pregnancy" and "yoga AND [post-natal OR post-partum]". Trials were considered if they were controlled and evaluated a yoga intervention. All studies were evaluated for methodological quality according to the Jadad scale and the Delphi List. Results. Six trials were identified: three were randomized controlled trials (RCTs) and three were controlled trials (CTs). The methodological quality and reporting ranged from 0-5 on the Jadad scale and from 3-6 on the Delphi List. Findings from the RCT studies indicate that yoga may produce improvements in stress levels, quality of life, aspects of interpersonal relating, autonomic nervous system functioning, and labour parameters such as comfort, pain, and duration. Conclusions. The findings suggest that yoga is well indicated for pregnant women and leads to improvements on a variety of pregnancy, labour, and birth outcomes. However, RCTs are needed to provide more information regarding the utility of yoga interventions for pregnancy.
