May 25, 2026 updated by: First Affiliated Hospital of Zhejiang University
This study intends to investigate the intervention efficacy of temporal interference stimulation (TI) on mood symptoms in depressed patients, as well as to explore the neuroimaging mechanisms of TI improvement in depressed patients using pre- and post-treatment magnetic resonance.

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.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Accepts Healthy Volunteers

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Temporal Interference Stimulation
Specific electrode sites are customized for the subject through magnetic resonance scanning, the deep nucleus cluster to be stimulated-nucleus accumbens is calibrated through electric field simulation before treatment, and the stimulation target can be accurately positioned by stimulating the specific electrode sites of the subject during treatment.
Device: Temporal Interference Stimulation
During the treatment period, all subjects were treated with a fixed time interference stimulation (TI) device at a frequency of 30 minutes twice a day, 5 days a week, for a total of 10 treatments. The output current intensity during treatment is 3.64 mA+4.36 mA.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Hamilton Depression Scale（HAMD-17)
Time Frame: 0-5 days
The Hamilton Depression Scale（HAMD-17) was used to assess the extent of the patient's depressive episodes, with higher scores representing more severe depression, and this scale was used to monitor the patient's improvement in depression before and after treatment.
0-5 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Montgomery-Asberg Depression Rating Scale（MADRS）
Time Frame: 0-5 days
The Montgomery-Asberg Depression Rating Scale (MADRS) is used to reflect the effectiveness of antidepressant treatment and to monitor changes in a patient's condition. The scale is a stand-alone scale whose ratings are based on a clinical interview with questioning about symptoms that leads to a rating of depression severity.
0-5 days
Beck Scale for Suicide Ideation (BSS)
Time Frame: 0-5 days
The Beck Suicidal Ideation Scale was used to assess the patients' suicidal ideation.
0-5 days
