Novel Objective Tool to Assess Tremor Reveals Unilateral Focused Ultrasound Improves Tremor Bilaterally.

ABSTRACT:

Background

Tremor in essential tremor and in tremor-dominant Parkinson's disease is assessed by subjective observations in patients undergoing focused ultrasound thalamotomy, a minimally invasive procedure intended to alleviate tremor in these patients.

Objective

To develop an objective tool for tremor analysis to be used before and after focused ultrasound thalamotomy treatment in the treated hand (contralateral to ablation) and non-treated (ipsilateral to ablation).

Methods

Using image processing and signal processing that utilized images of a Archimedes spiral drawing, we created a tool to analyze tremor. First, we showed that the proposed tool reproduces known clinical dynamics on the treated hand, and then we used it to evaluate the clinical dynamics on the non-t
