Accurate Telemonitoring of Parkinson's Disease Progression by Noninvasive Speech Tests

Nonlinear speech analysis algorithms mapped to a standard metric achieve clinically useful quantification of average Parkinson's disease symptom severity.

The standard reference clinical score quantifying average Parkinson's disease (PD) symptom severity is the Unified Parkinson's Disease Rating Scale (UPDRS). At present, UPDRS is determined by the subjective clinical evaluation of the patient's ability to adequately cope with a range of tasks. In this study, we extend recent findings that UPDRS can be objectively assessed to clinically useful ac...

A Multiple-Classifier Framework for Parkinson's Disease Detection Based on Various Vocal Tests

Recently, speech pattern analysis applications in building predictive telediagnosis and telemonitoring models for diagnosing Parkinson's disease (PD) have attracted many researchers. For this purpose, several datasets of voice samples exist; the UCI dataset named "Parkinson Speech Dataset with Multiple Types of Sound Recordings" has a variety of vocal tests, which include sustained vowels, word...

Accurate telemonitoring of Parkinson’s disease symptom severity using nonlinear speech signal processing and statistical machine learning

Repetitive speech phenomena in Parkinson's disease.

OBJECTIVES Repetitive speech phenomena are morphologically heterogeneous iterations of speech which have been described in several neurological disorders such as vascular dementia, progressive supranuclear palsy, Wilson's disease, and Parkinson's disease, and which are presently only poorly understood. The present, prospective study investigated repetitive speech phenomena in Parkinson's diseas...

Oral and Laryngeal Diadochokinetic Rate in Multiple Sclerosis: Relationship to Disease Progression

Background: The first purpose of this study was to investigate the rate of oral and laryngeal Diadochokinesis (DDK) in Multiple Sclerosis (MS) patients in comparison with healthy people. The second goal was to determine if DDK rate has any relationship with the disease progression. Methods: In this cross-sectional study, two groups were enroll...
