Using taVNS to Modulate Cardiovascular Function in Individuals With Neurologic Disease

Using taVNS to Modulate Cardiovascular Function in Individuals With Neurologic Disease

The purpose of this study is to find out whether a type of gentle nerve stimulation, called transcutaneous auricular Vagus Nerve Stimulation (taVNS), can help improve how the body regulates heart rate and blood pressure in people with Parkinson's Disease (PD). Problems with heart rate and blood pressure control are common and can make it harder for people to exercise or do daily activities. By using this non-invasive form of nerve stimulation and testing how it affects the body's natural responses, this study hopes to learn if taVNS could be a helpful tool to support physical therapy and improve overall function.
