Subthalamic Nucleus-Targeted Transcranial Temporal Interference Stimulation for Motor and Non-Motor Symptoms in Parkinson's Disease

Официальное название

Study on the Efficacy and Safety of Subthalamic Nucleus (STN)-Targeted Transcranial Temporal Interference Stimulation (tTIS) for Motor and Non-Motor Symptoms in Parkinson's Disease (PD): A Randomized, Double-Blind, Controlled Exploratory Trial

Обзор

Transcranial temporal interference stimulation (tTIS) is a non-invasive deep brain stimulation method. This study aims to comprehensively explore the efficacy and safety of bilateral subthalamic nucleus (STN) tTIS on motor and non-motor symptoms in patients with Parkinson's disease (PD).

Подробное описание

This is a single-center, randomized, double-blind, sham-controlled trial for Parkinson's disease (PD). The transcranial temporal interference stimulation (tTIS) intervention period is 5 days, with follow-up assessments conducted immediately after the intervention, 10 days post-intervention, and 30 days post-intervention. The real stimulation group receives bilateral subthalamic nucleus (STN) -targeted tTIS once daily for 5 days. Stimulation parameters: carrier frequencies of 2000/2130 Hz (Δf = 130 Hz), with stimulation lasting 20 minutes on each side. Before the intervention, T1-weighted structural images are acquired for each subject, and computational modeling based on an individual head model is performed to optimize electrode placement, individually focusing on the target side STN region. The sham group follows the same procedure but does not receive effective stimulation. The sham stimulation group receives only 30 seconds of fade-in/fade-out current at the beginning and end of the stimulation period to ensure blinding.

Вмешательства

• Устройство real transcranial temporal interference stimulation
  tTIS was targeted at the bilateral STN, with stimulation delivered once daily for 20 minutes per session, for a total of five consecutive days.
• Устройство sham transcranial temporal interference stimulation
  The sham stimulation is administered using the same procedure as the real tTIS.
