Официальное название

Efficacy and Safety Assessment of Temporal Interference Stimulation to Improve Bipolar Depression: a Randomized Controlled Study

Обзор

The aim of this study was to explore the efficacy and safety of temporal interference stimulation to improve bipolar depression, as well as to explore the corresponding neuroimaging mechanisms using magnetic resonance and electroencephalogram to provide novel intervention protocols and objective indicators of efficacy prediction for depressive episodes in bipolar disorder.

Вмешательства

• Устройство Temporal Interference Stimulation
  A non-invasive, non-invasive method of deep brain electrical stimulation utilizing high-frequency electric field interactions to produce a low-frequency envelope to modulate neural activity.
• Устройство Sham Temporal Interference Stimulation
  The same machine was used as the temporal Interferenc real stimulus, with current creep only 20 seconds before stimulus onset to simulate the real stimulus sensation.
