Transcranial Temporal Interference Stimulation (tTIS) To Modulate Essential Tremor

Starting soon · Not applicable

Conditions studied: Essential Tremor

In brief

The goal of this proof-of-concept study is to examine the effects of a relatively new, non-invasive electrical current-based technique, transcranial temporal interference stimulation (tTIS), in patients with Essential Tremor (ET). TTIS is delivered via a Digitimer Ltd. stimulator, the "DS5 Isolated Bipolar Constant Current Stimulator." The method enables targeting deep cerebral structures to selectively modulate neurons. The structure of interest in the present study is the ventralis intermedius (VIM) of the thalamus, which plays a key role in tremor generation in people with essential tremor. Therefore, techniques targeting the VIM nucleus can potentially improve the tremor and the quality of life in the long term, as is the case with MRI-guided high-intensity focused ultrasound (MRgHIFU). Despite its efficiency, MRgHIFU can lead to side effects that could benefit from improved predictive modeling. In our proof-of-concept study, the investigators aim to examine whether tTIS of the VIM nucleus can alter tremor characteristics and, therefore, mimic the effects of MRgHIFU. This work would pave the way for future clinical trials to design prediction tools for MRgHIFU if the investigators can demonstrate the positive impact of tTIS.
