Home-Based Wearable rTMS Therapy for Moderate to Severe Depression
Multicenter Randomized Controlled Trial Assessing Wearable Repetitive Transcranial Magnetic Stimulation for Home-Based Treatment of Depression
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 .

安慰剂比较：rTMS-Tiny Sham Stimulation Group
The key difference lies in the use of a sham stimulation coil instead of the rTMS-Tiny active treatment coil.
