Transcutaneous Auricular Vagus Nerve Stimulation in Patients With Narcolepsy Type 1

January 26, 2024 updated by: Liu Yonghong

Safety and Efficacy of Transcutaneous Auricular Vagus Nerve Stimulation in Patients With Narcolepsy Type 1: A Double-blind, Randomized, Sham-controlled Trial

The study aimed to examine the efficacy and safety of tVNS as a complementary approach for NT1 by conducting a double-blind, randomized, sham-controlled trial. The specific objectives of the study were as follows: To evaluate the effects of complementary tVNS on the ability to maintain wakefulness, severity of narcolepsy, mood and quality of life in patients with NT1

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Transcutaneous auricular vagus nerve stimulation
The tVNS protocol consisted of a 500-µs pulse width and 25-Hz frequency, with a 30-second on/off cycle. The stimulation was applied for a total of 2 hours per day, divided into four 30-minute periods. At least one of these periods occurred within 2 hours before bedtime.The stimulation point was only limited to the left auricular concha.
Device: transcutaneous auricular vagus nerve stimulation
Transcutaneous auricular vagus nerve stimulation (tVNS) is a newly developed treatment for neuromodulation. It offers advantages such as being non-invasive, cost-effective, and not requiring battery changes, unlike invasive vagus nerve stimulation (iVNS). The auricular branch of the vagus nerve, which is the only afferent branch distributed on the surface of the human body, can be directly stimulated to produce effects similar to classic vagus nerve stimulation (VNS)
Sham Comparator: sham Transcutaneous auricular vagus nerve stimulation
The same stimulation parameters were used for stVNS, but the stimulation point was the left earlobe.
