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, 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.

Primary Outcome Measures:
  • Static Balance [ Time Frame: Week 0 and Week 8. ] [ Designated as safety issue: No ]
    Measures will be assessed at baseline (Week 0) and immediately after the 8-week intervention at Week 8.

Secondary Outcome Measures:
  • Perceived Stress Scale [ Time Frame: Week 0 and Week 8 ] [ Designated as safety issue: No ]
    Measures will be assessed at baseline (Week 0) and immediately after the 8-week intervention at Week 8.

  • Profile of Mood States - Short Form [ Time Frame: Week 0 and Week 8 ] [ Designated as safety issue: No ]
    Measures will be assessed at baseline (Week 0) and immediately after the 8-week intervention at Week 8.

  • Exit Survey [ Time Frame: Week 8 ] [ Designated as safety issue: Yes ]
    The exist survey is administered immediately after the intervention during Week 8.

  • Fear of Falling Questionnaire [ Time Frame: Week 0 and Week 8 ] [ Designated as safety issue: No ]
    Measures will be assessed at baseline (Week 0) and immediately after the 8-week intervention at Week 8.

Other Outcome Measures:
  • Treatment Validation [ Time Frame: Week 0, Week 4 and Week 8 ] [ Designated as safety issue: No ]

    Three measures will be collected to assess the benefits of the AYT, compliance, fidelity of treatment and evaluate the participant's experience.

    1. The Philadelphia Mindfulness Scale (PHLMS).
    2. Practice/Homework Logs.
    3. Treatment Fidelity.

  • Physical Function [ Time Frame: Week 0 and Week 8 ] [ Designated as safety issue: No ]
    Body Mass Index (BMI), systemic blood pressure, and respiratory rate, the International Physical Activity Questionnaire (IPAQ) and flexibility measures.
