Yoga Training and Retinal Vasculature With Parkinson's Disease

The Impact of Cued High-speed Interval Yoga (YogaCue) on Retinal Microvasculature, Mitochondrial Function, and Cognition in Persons With Parkinson's Disease.

This study will compare the impact of a novel high-speed, cued yoga program to a standard yoga program on retinal microvasculature, cognition and neuromuscular function in persons with Parkinson's disease.

Inclusion Criteria:

1. Parkinson's disease (H&Y 1, 2, and 3) confirmed by pretest administration of the UPDRS,
2. 55-90 years of age,
3. Montreal Cognitive Assessment > 17.

Exclusion Criteria:

1. Uncontrolled cardiovascular or neuromuscular diseases that prevent participation in a training program;
2. cerebrovascular disease;
3. documented HIV infection or other immunodeficiency syndrome;
4. any systemic inflammatory or autoimmune conditions such as rheumatoid arthritis, systemic lupus erythematosus, or other serious concomitant medical illness;
5. a history of ocular surgeries (except for cataract surgery more than 6 months ago) or other ocular diseases;
6. bilateral moderate or severe cataracts;
7. refractive errors of myopia, hyperopia and/or astigmatism more than 6.0 Diopters.
