The Efficacy and Safety of Transcutaneous Auricular Vagus Nerve Stimulation for Depression in PD
Sponsor: The First Affiliated Hospital with Nanjing Medical University
Summary
This study is a double blind comparative study examining the effectiveness of the transcutaneous auricular vagus nerve stimulation treatment on Parkinson's disease patients with depression. The investigators hypothesize that taVNS will improve depression and cortical activity in Parkinson's disease patients with depression.

Active Transcutaneous auricular vagus nerve stimulation
Active Transcutaneous auricular vagus nerve stimulation:Two modified dot-like electrodes delivered the stimulation to the cymba conchae of left ear in the vicinity of the auricular branch vagus nerve.Stimulation parameters: frequency = 20/4 Hz; pulse width = 200 μs; 20 Hz lasting 7 seconds, alternated with 4 Hz lasting 3 seconds#repeat until 30 min.Every PD patient received stimulation twice daily ,30 minutes each time, for 14 consecutive days. The stimulation intensity was set as the maximum value the patient could tolerate without causing pain.Sham Transcutaneous auricular vagus nerve stimulation:Two modified dot-like electrodes delivered the stimulation to the cymba conchae of left ear in the vicinity of the auricular branch vagus nerve. The stimulation paradigm was identical to that of the real stimulation group. The stimulation intensity was set as the maximum value the patient could tolerate without causing pain.
