Individualized Temporally Interfering Electrical Stimulation in Major Depressive Disorder
Closed-Loop Bio-Machine Interaction System and Applications in Psychiatric Diagnosis and Treatment
Temporally interfering (TI) electrical stimulation is a novel noninvasive neuromodulation technique with high spatial resolution. Although its effects on human brain function and behavior have been increasingly investigated, its clinical utility in major depressive disorder (MDD) has not been established. This trial aims to evaluate the efficacy and safety of TI electrical stimulation in MDD patients.

Detailní popis
This is a multicenter, double-blind, randomized, sham-controlled trial including three parallel arms: (1)single-target active stimulation targeting the right primary auditory cortex (A1); (2) dual-target active stimulation targeting the right A1 and the right dorsolateral prefrontal cortex (DLPFC); (3)sham stimulation. All interventions will be delivered over two consecutive weeks, comprising ten treatment visits, with 20 minutes of stimulation applied to each target.

Experimentální: single-target active TI electrical stimulation group
|
Single-target active stimulation targeting the right primary auditory cortex (A1), each target stimulation phase will last 20 minutes, including a 30-second ramp-up at onset and a 30-second ramp-down at termination. Alternating currents with frequencies of f1 = 2000 Hz and f2 = 2040 Hz will be delivered through the two electrode pairs, and the total current intensity across the two electrode pairs will be fixed at 4 mA (AC, peak-to-base). The intervention will be administered over two consecutive weeks, with participants receiving stimulation on five days per week. |
|
Experimentální: dual-target active TI electrical stimulation group
|
Dual-target active stimulation targeting the right A1 and the right dorsolateral prefrontal cortex (DLPFC), each target stimulation phase will last 20 minutes, including a 30-second ramp-up at onset and a 30-second ramp-down at termination. For each target, two pairs of electrodes will be used; the alternating current frequency and total stimulation intensity will be the same as those in the single-target active TI electrical stimulation group.The intervention will be administered over two consecutive weeks, with participants receiving stimulation on five days per week. |
|
Falešný srovnávač: sham TI electrical stimulation group
|
Sham TI electrical stimulation group will follow the same session duration, treatment frequency, and procedural setup as the active stimulation groups. However, electrical stimulation will be limited to an initial 30-second ramp-up followed immediately by a 30-second ramp-down, after which no current will be delivered for the remainder of the session. |
