Objective tremor monitoring using tri-axis accelerometer in MRgFUS thalamotomy for essential tremor: a feasibility study.

ABSTRACT:

Background

Magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy has shown promising results in treating pharmaco-resistant essential tremor (ET). This incisionless, image-guided technique targets the ventralis intermedius nucleus of the thalamus with precision, sparing surrounding eloquent tissue.Objective: This study aims to assess the efficacy of MRgFUS thalamotomy in improving tremor among ET patients, as objectively measured by a tri-axis accelerometer, and to compare these objective measures with the conventional Clinical Rating Scale for Tremor (CRST).Design: Prospective observational study.

Methods

Ten ET patients (aged 68.1 ± 11.8 years) received the MRgFUS treatment. Improvements in tremor severity were assessed using primary (CRST), with additional mea
