Обзор
This study aims to evaluate the efficacy and safety of Temporal Interference (TI) stimulation in treating patients with post-traumatic stress disorder (PTSD) and to explore its potential neural mechanisms using magnetic resonance imaging (MRI) ,magnetoencephalography(MEG),electroencephalography (EEG).
Подробное описание
This open-label, single-arm clinical trial aims to evaluate the efficacy and safety of Temporal Interference (TI) stimulation targeting the bilateral amygdala in patients with post-traumatic stress disorder (PTSD).
All enrolled patients receive active TI stimulation delivered twice daily for 20 minutes per session over 7 consecutive days, followed by follow-up assessments for up to 3 months. Comprehensive clinical assessments, self-reported symptom scales, magnetic resonance imaging(MRI), magnetoencephalography(MEG),electroencephalography (EEG), and cognitive function tests are conducted before and after the treatment to ensure data consistency.
Вмешательства
- Устройство TI stimulation device (nerviox-1000)
The TI stimulation device delivers temporally interfering electrical fields with a 160 Hz envelope frequency, generated by high-frequency carrier waves (2000 Hz and 2160 Hz). Stimulation is applied for 20 minutes per session, with a peak current of 3-4 mA per channel, adjusted based on individual tolerance. The stimulation target is the bilateral amygdala. Stimulation is administered twice daily, with the treatment phase lasting 7 consecutive days.
Первичные конечные точки
- post-traumatic stress disorder symptoms improvement [Срок оценки: Baseline, immediately post-treatment (Day 7), and at follow-up visits (Week 1, Week 4, Month 3 post-treatment)]
