Title: Development of a Yoga Intervention for Symptoms Related to Severe Visual Impairment
Brief Summary: This study aims to provide novel information on the feasibility of yoga interventions for secondary symptoms related to severe vision loss, such as sleep disturbances, negative mood states, fall risk and balance. This information will be important for determining safe, cost-effective and reliable practices for the benefits of yoga as an alternative means for improved health and well-being. A yoga intervention that is integrative and evidence-based will benefit the blind population through effective treatments and prevention of secondary symptoms as well as serve to inform rehabilitation specialists, educators, and clinicians in the future.
