June 2, 2026 updated by: Xiaoying Zhu, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine

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

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).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Receipt of non-invasive neuromodulation interventions such as transcranial magnetic stimulation or transcranial electrical stimulation within the past six months.
  • Presence of contraindications to MRI or inability to tolerate MRI examination.
