At-home taVNS for Parkinson's Disease

This trial aims to determine if transcutaneous auricular nerve stimulation (taVNS), a non-invasive method that stimulates nerves in the ear, can alleviate symptoms of Parkinson's Disease. Participants will use the device at home daily for eight weeks to assess its practicality and effectiveness in improving symptoms like walking and balance. The trial also examines how taVNS affects brain connections in individuals with Parkinson's Disease. It suits those diagnosed with Parkinson's Disease who experience walking or balance issues and have been stable on their medication for at least 30 days. As an unphased trial, this study provides a unique opportunity to explore innovative treatments and contribute to advancing Parkinson's Disease research.

The trial requires that you stay on stable doses of your current dopaminergic medications for at least 30 days before joining. However, you cannot participate if you are using certain medications like B-Blockers, dopamine blocking agents (except quetiapine or pimavenserin in stable doses), and some others. It's best to discuss your specific medications with the study doctor.

Research has shown that transcutaneous auricular nerve stimulation (taVNS) is generally safe. Studies have found that people tolerate taVNS well, with no reports of serious side effects. Although some minor side effects have been noted, they are not considered serious. For example, one study found that taVNS was safely used in people with Parkinson's Disease, suggesting it might help manage symptoms without major risks. Overall, while minor side effects can occur, research indicates that taVNS is safe.¹²³⁴⁵

Unlike the standard treatments for Parkinson's Disease, which often include medications like levodopa that address symptoms by boosting dopamine levels in the brain, transcutaneous auricular vagus nerve stimulation (taVNS) offers a unique approach. This treatment is applied through the skin to stimulate the vagus nerve via the ear, which could potentially modify brain activity and improve motor function. Researchers are excited about taVNS because it can be administered at home, making it more convenient for patients and potentially offering a non-invasive alternative to existing therapies.

Research has shown that transcutaneous auricular nerve stimulation (taVNS) may benefit people with Parkinson's Disease. In this trial, participants will undergo one in-person taVNS session followed by 8 weeks of at-home sessions. Studies suggest that taVNS can ease movement problems, as indicated by lower scores on Parkinson's assessments, and improve other issues like quality of life. It appears to enhance brain function, supporting both movement and mental functions, which benefits Parkinson's patients. Some research also found that it can help people walk faster and take longer steps. However, results can vary, and some studies show only modest improvements, particularly with movement problems. Overall, early findings suggest taVNS could be a promising way to manage Parkinson's symptoms.²⁶⁷⁸⁹
