Progression of glaucoma associated with the Sirsasana (Headstand) yoga posture
ABSTRACT This article reports a case of progressive glaucomatous optic neuropathy and visual field loss that occurred in a patient who practiced the Sirsasana (headstand) yoga posture on a daily basis for many years. Visual field analysis was performed through standard automated perimetry. Intraocular pressure (IOP) was measured through pneumotonometry in the sitting position and in the head-down position. Stereo-optic disc photographs were obtained. IOP increased significantly in the head-down position. Optic disc evaluation revealed a new disc hemorrhage in the left eye. Visual field analysis over a period of 2 y showed progression of a superior arcuate defect in the left eye. Transient increases in IOP associated with the yoga headstand posture may lead to progressive glaucomatous optic nerve damage and visual field loss.

ABSTRACT: 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. 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". 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. 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.BioPsychoSocial Medicine 12/2015; 9(1). DOI:10.1186/s13030-015-0037-1

ABSTRACT: The objective of this study was to assess the effect of a yoga intervention on psychological health in older adults. A randomized controlled trial study, conducted at two North Florida facilities for older adults. Subjects were 98 older adults, ages 65 - 92. Participants were randomly assigned to chair yoga, chair exercise, and control groups and assessed pre-intervention, post-intervention, and one-month follow-up on the State Anger Expression Inventory, State Anxiety Inventory, Geriatric Depression Scale, Lawton's PGC Morale Scale, General Self-Efficacy Scale, Chronic Disease Self-Efficacy Scales, and Self-Control Schedule. Yoga participants improved more than both exercise and control participants in anger (Cohen's d = 0.89 for yoga versus exercise, and 0.90 for yoga versus control, pretest to posttest; and d = 0.90 and 0.72, pretest to follow-up), anxiety (d = 0.27, 0.39 and 0.62, 0.63), depression (d = 0.47, 0.49 and 0.53, 0.51), well-being (d = 0.14, 0.49 and 0.25, 0.61), general self-efficacy (d = 0.63, 1.10 and 0.30, 0.85), and self-efficacy for daily living (d = 0.52, 0.81 and 0.27, 0.42). Changes in self-control moderated changes in psychological health. Over a six-week period, our findings indicate yoga's potential for improving psychological health in older adults.Journal of Physical Activity and Health 12/2013; 11(7).
