About this trial

Background and Rationale

With rapid economic development and increasing societal pressures, the incidence of neuropsychiatric disorders has risen annually, ranking as the leading cause of disability worldwide and imposing a severe societal burden. Among these, depressive disorders represent a primary contributor. However, the efficacy and accessibility of transcranial magnetic stimulation (TMS) for depression face significant challenges. Key limitations include:

Low targeting accuracy with traditional localization methods. Limited clinical penetration of individualized precision paradigms .

In this context, wearable repetitive TMS (wrTMS) technology offers a transformative solution. The rTMS-Tiny device, developed by the Institute of Automation, Chinese Academy of Sciences, exemplifies this innovation with the following features:

Battery-powered with a pulse capacity exceeding 8,000 pulses per charge. Ultra-lightweight design: Total system weight \<3 kg, coil helmet \<2 kg (10% of conventional devices).

Performance parity: Comparable efficacy to standard rTMS systems while enabling protocols like Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT) .

Advantages of rTMS-Tiny Portable Design and Wearable Application Ergonomically optimized helmet allows near-unrestricted daily activities during treatment .

Streamlined Operational Workflow Simplified protocols significantly reduce clinician workload . Enhanced Treatment Tolerability Improved comfort increases treatment completion rates and long-term adherence, directly enhancing therapeutic outcomes .

These advantages enable high-dose, intensive regimens (e.g., SAINT-like protocols) in routine clinical practice .

Scientific Imperative for a Multicenter RCT

A multicenter randomized controlled trial (RCT) of rTMS-Tiny is clinically and scientifically warranted to:

Test two core hypotheses:

Hypothesis 1: Efficacy of rTMS-Tiny in reducing depressive symptoms. Hypothesis 2: Safety of home-based rTMS-Tiny administration . Generate high-level evidence to advance neuromodulation into an era of precision, personalization, and artificial intelligence-driven therapy .

Eligibility criteria

Qualifiers

Diagnostic and Severity Requirements Meet DSM-5 criteria for Major Depressive Disorder (MDD). Current moderate-to-severe depressive episode, defined by Hamilton Depression Rating Scale 17-item (HAMD-17) score ≥18 .

Pharmacological Stability Stable antidepressant regimen for ≥4 weeks prior to enrollment, restricted to SSRIs (Selective Serotonin Reuptake Inhibitors).

Technical Feasibility Medically eligible for both structural MRI and resting-state functional MRI (fMRI) examinations.

Disqualifiers

Psychiatric Comorbidities Any concurrent psychiatric diagnosis (e.g., autism spectrum disorder, severe cognitive impairment, epilepsy, mania, psychosis) .

Neurological Structural Abnormalities Structural brain lesions increasing seizure risk or disrupting neural connectivity (e.g., brain tumors, history of stroke).

Systemic Medical Conditions Unstable cardiovascular, respiratory, hepatic, renal diseases, or active malignancies.

Contraindications to Procedures TMS contraindications: Metallic implants, pacemakers, history of epilepsy. MRI contraindications: Ferromagnetic implants, claustrophobia requiring sedation.
