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 a treatment called transcutaneous vagus nerve stimulation (tVNS), which uses gentle electrical pulses applied to the ear to help manage Parkinson's disease symptoms. Researchers believe this treatment may help improve voice quality, speech, swallowing, balance, and tremor. Half of the participants will receive the active treatment on a specific part of the ear, while the other half will receive a placebo (fake) version to see if the real treatment actually works.
Many people with Parkinson's disease struggle with voice, speech, and swallowing problems, as well as balance and movement difficulties. Current treatments don't fully address all of these symptoms, so researchers are investigating whether this treatment might help improve quality of life for patients.
You would visit the research center three times per week for four weeks to receive 30-minute electrical stimulation sessions applied to your ear, along with one speech therapy session and one physical therapy session per week. The study uses a double-blind design, meaning neither you nor the researchers will know whether you're receiving the active treatment or the placebo version until the study ends. You'll also have initial tests to measure your voice, speech, swallowing, balance, movement, and other Parkinson's symptoms, and these same tests will be repeated at the end to see if there's improvement.
