effect of 12 weeks of Yoga training on the somatization psychological symptoms and stress related biomarkers of healthy women
Biopsychosocial Medicine, 2014Co-Authors: Kazufumi Yoshihara, Takakazu Oka, Tetsuya Hiramoto, Chiharu Kubo, Nobuyuki SudoAbstract:Background: Previous studies have shown that the practice of Yoga reduces perceived stress and negative feelings and that it improves psychological symptoms. Our previous study also suggested that long-term Yoga training improves stress-related psychological symptoms such as anxiety and anger. However, little is known about the beneficial effects of Yoga practice on somatization, the most common stress-related physical symptoms, and stress-related biomarkers. We performed a prospective, single arm study to examine the beneficial effects of 12 weeks of Yoga training on somatization, psychological symptoms, and stress-related biomarkers. Methods: We recruited healthy women who had no experience with Yoga. The data of 24 participants who were followed during 12 weeks of Yoga training were analyzed. Somatization and psychological symptoms were assessed before and after 12 weeks of Yoga training using the Profile of Mood State (POMS) and the Symptom Checklist-90-Revised (SCL-90-R) questionnaires. Urinary 8-hydroxydeoxyguanosine (8-OHdG), biopyrrin, and cortisol levels were measured as stress-related biomarkers. The Wilcoxon signed-rank test was used to compare the stress-related biomarkers and the scores of questionnaires before and after 12 weeks of Yoga training. Results: After 12 weeks of Yoga training, all negative subscale scores (tension-anxiety, depression, anger-hostility, fatigue, and confusion) from the POMS and somatization, anxiety, depression, and hostility from the SCL-90-R were significantly decreased compared with those before starting Yoga training. Contrary to our expectation, the urinary 8-OHdG concentration after 12 weeks of Yoga training showed a significant increase compared with that before starting Yoga training. No significant changes were observed in the levels of urinary biopyrrin and cortisol after the 12 weeks of Yoga training. Conclusions: Yoga training has the potential to reduce the somatization score and the scores related to mental health indicators, such as anxiety, depression, anger, and fatigue. The present findings suggest that Yoga can improve somatization and mental health status and has implications for the prevention of psychosomatic symptoms in healthy women.

Development of a recumbent isometric Yoga program for patients with severe chronic fatigue syndrome/myalgic encephalomyelitis: A pilot study to assess feasibility and efficacy
BioPsychoSocial Medicine, 2017Co-Authors: Takakazu Oka, Hisako Wakita, Keishin KimuraAbstract:Background Our previous randomized controlled trial demonstrated that isometric Yoga in a sitting position reduces fatigue in patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). However, some patients experience difficulties sitting or practicing isometric Yoga in a sitting position for long periods. To date, therapeutic interventions for patients with severe symptoms have not been established. Therefore, we developed a recumbent isometric Yoga program, which takes approximately 20 min to complete, designed to reduce fatigue in patients with severe CFS/ME. The aim of this pilot study was to assess the feasibility, safety, and usefulness of this program. Methods This pilot study included 12 adult patients with CFS/ME. Six patients were reluctant to practice isometric Yoga in a sitting position because of the severity of their fatigue (group 1). The remaining six patients had previously practiced isometric Yoga in a sitting position (group 2). For 3 months, the patients of both groups practiced recumbent isometric Yoga every 2 to 4 weeks with a Yoga instructor and at home on other days if they could. The short-term effects of isometric Yoga on fatigue were assessed using the Profile of Mood Status (POMS) questionnaire immediately before and after their final session with the Yoga instructor. The long-term effects of isometric Yoga on fatigue were assessed using the Chalder Fatigue Scale (FS) questionnaire before and after the intervention period. Adverse events, satisfaction with the program, and preference of Yoga position (sitting or recumbent) were also recorded. Results All subjects completed the intervention. In both groups, the POMS fatigue score was significantly decreased after practicing the 20-min Yoga program and the Chalder FS score was decreased significantly after the 3-month intervention period. There were no serious adverse events. All subjects in group 2 preferred the recumbent isometric Yoga program over a sitting Yoga program. Conclusions This study suggests that recumbent isometric Yoga is a feasible and acceptable treatment for patients with CFS/ME, even for patients who experience difficulty practicing isometric Yoga in the sitting position.

A large-scale survey of adverse events experienced in Yoga classes
BioPsychoSocial Medicine, 2015Co-Authors: Tomoko Matsushita, Takakazu OkaAbstract:Background Yoga is a representative mind-body therapy of complementary and alternative medicine. In Japan, Yoga is practiced widely to promote health, but Yoga-associated adverse events have also been reported. To date, the frequencies and characteristics of Yoga-related adverse events have not been elucidated. This study was conducted to elucidate the frequencies and characteristics of adverse events of Yoga performed in classes and the risk factors of such events. Methods The subjects were 2508 people taking Yoga classes and 271 Yoga therapists conducting the classes. A survey for Yoga class attendees was performed on adverse events that occurred during a Yoga class on the survey day. A survey for Yoga therapists was performed on adverse events that the therapists had observed in their students to date. Adverse events were defined as “undesirable symptoms or responses that occurred during a Yoga class”. Results Among 2508 Yoga class attendees, 1343 (53.5%) had chronic diseases and 1063 (42.3%) were receiving medication at hospitals. There were 687 class attendees (27.8%) who reported some type of undesirable symptoms after taking a Yoga class. Musculoskeletal symptoms such as myalgia were the most common symptoms, involving 297 cases, followed by neurological symptoms and respiratory symptoms. Most adverse events (63.8%) were mild and did not interfere with class participation. The risk factors for adverse events were examined, and the odds ratios for adverse events were significantly higher in attendees with chronic disease, poor physical condition on the survey day, or a feeling that the class was physically and mentally stressful. In particular, the occurrence of severe adverse events that interfered with subsequent Yoga practice was high among elderly participants (70 years or older) and those with chronic musculoskeletal diseases. Conclusions The results of this large-scale survey demonstrated that approximately 30% of Yoga class attendees had experienced some type of adverse event. Although the majority had mild symptoms, the survey results indicated that attendees with chronic diseases were more likely to experience adverse events associated with their disease. Therefore, special attention is necessary when Yoga is introduced to patients with stress-related, chronic diseases.
