Evaluation of the effects of deep brain stimulation of the subthalamic nucleus and levodopa treatment on Parkinsonian voice using perturbation nonlinear dynamic and perceptual analysis

摘要

Background/AimsTo quantify aperiodic phonation, nonlinear dynamic methods of acoustic voice analysis, such as correlation dimension, have been shown to be useful. The purpose of this study is to evaluate the validity of nonlinear dynamic analysis as a voice analysis tool for the Parkinson’s disease (PD) treatment effects of deep brain stimulation (DBS) and levodopa.
