Study Summary

This trial will use ultrasound to investigate how different stimulation parameters of VNS devices affect the human vagus nerve. Results will inform the development of neural interfaces for various clinical applications.

Who is the study for?
This trial is for English-speaking adults aged 18-40 with epilepsy who have health insurance and an implanted VNS device. It's not for pregnant individuals, those whose vagus nerve isn't visible on ultrasound, or if the VNS electrodes aren't suitably placed. Smokers must abstain on experiment day, and participants can't have significant carotid artery plaque.Check my eligibility
What is being tested?
The study tests how different stimulation settings of a Vagus Nerve Stimulation (VNS) device affect nerve fibers in the human vagus nerve. Using ultrasound-guided microneurography, researchers record nerve activity to guide future development of neural interfaces for clinical applications.See study design
What are the potential side effects?
While specific side effects are not listed, this type of procedure may cause discomfort at the electrode insertion site, potential temporary voice changes due to vagus nerve stimulation, or mild pain from standing during tilt-table testing.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

To what extent does VNS pose a risk to human health?

"The limited evidence gathered for VNS's safety and efficacy leads to a score of 1 on the Power team's scale."

Answered by AI

Is this research protocol restricted to adults below the age of fourty?

"Those between 18 and 40 are eligible to partake in this trial. However, there are 109 clinical studies for minors under the age of 18 and 163 trials intended for adults aged 65 or older."

Answered by AI

Is there still capacity for participants in this experiment?

"According to the clinicaltrials.gov, this particular study is not currently seeking volunteers. It was originally posted on October 1st 2023 and has since been updated for the last time on September 18th 2023. Although it's no longer recruiting participants, there are 253 other relevant trials actively enrolling patients right now."

Answered by AI

Do I qualify to participate in this medical experiment?

"Candidates of this study must possess diagnosed epilepsy and be between 18 to 40 years old. This experiment is aiming to recruit a total of 60 participants."
