This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing transcutaneous vagus nerve stimulation (tVNS)—a gentle electrical stimulation applied to the ear—to see if it can help improve both movement and non-movement symptoms of Parkinson's disease. Researchers will compare people who receive the real treatment to those who receive a sham (placebo) version, with all participants also receiving speech and physical therapy. The main focus is whether this treatment can improve voice quality, swallowing, and balance while reducing tremor and other symptoms that affect daily life.
Parkinson's disease causes problems with movement, speech, swallowing, and many other body functions that seriously impact quality of life. Current treatments have limitations, so researchers are exploring whether stimulating a major nerve in the body through the ear might help reduce these symptoms and improve how people feel and function.

You would visit the clinic three times per week for 4 weeks to receive 30-minute electrical stimulation sessions applied to your ear. You'll also attend one speech therapy session and one physical therapy session each week during those 4 weeks. Half the participants will receive real stimulation to the part of the ear connected to the vagus nerve, while the other half will receive sham stimulation (you won't know which group you're in). Before, during, and after the study, researchers will measure your voice quality, swallowing ability, tremor, balance, walking, mood, and overall quality of life.
