Intrapatient Comparison of STN and GPi tTIS in PD

China100 participantsStarted 2025-04-23

Plain-language summary

The goal of this clinical trial is to investigate the therapeutic efficacy of tTIS in patients with Parkinson's disease and to evaluate the immediate effects and conduct intrapatient comparisons of individualized 130 Hz Subthalamic Nucleus-transcranial Temporal Interference Stimulation (STN-tTIS) and Globus Pallidus Internus-transcranial Temporal Interference Stimulation (GPi-tTIS) on motor symptoms in patients with early to mid-stage Parkinson's Disease (PD) during "off" medication states. The main questions this study aims to answer are: 1. Can tTIS significantly improve the motor symptoms of patients with Parkinson's disease? 2. Is the therapeutic effect of STN-tTIS superior to that of GPi-tTIS?
