Perceptual analysis is widely used in clinical practice to assess motor speech disorders such as dysarthria. Unfortunately, there is no standardised tool available in French. The purpose of this study was first to develop a perceptual rating system modelled after systems currently used in the English literature and second to determine its reliability. We evaluated 33 dimensions using a 5-point scale. The production of 10 dysarthric patients were rated by 9 clinicians during both spontaneous speech and a reading task. Intra judge reliability (at 1-point) was about 90 percent, while inter judge reliability was about 80 percent. Ratings were comparable for the spontaneous speech and the reading task. Perceptual analysis of dysarthria is an easy and reproducible approach that can be used for the initial evaluation and for the follow up of dysarthric patients.

Autoimmune cerebellar ataxia (ACA) is a cerebellar syndrome induced by autoimmune reactions and its onset is induced by malignant tumors, prodromic infection, and gluten allergy. Its clinical symptoms include gait disorder, limb ataxia, dysarthria, and dysphagia. According to , the diagnosis of ACA is based on the following points: 1.

: This study aimed to determine the positive predictive value of our NMD Suspicion Criteria in the diagnosis of NMDs. Other clinical factors routinely examined in our voice and swallowing examinations were also investigated to see if they had a significant association with the diagnosis of NMDs. : This study retrospectively investigated the medical charts of patients who visited our Voice and Swallowing outpatient clinic between 2013 and 2022.

Objectives: The purpose of this study was to analyze cepstral changes following intensive voice-focused treatment in Spanish speakers with Parkinson's disease (PD). A secondary aim of the study was to explore the relationship between cepstral values across time and perceptual data across speech subsystems.
Study Design/methods: This study followed a one-group pretest-post test design.
Intensive Speech Therapy for Hypokinetic Dysarthria in Parkinson's Disease: Targeting the Five Subsystems of Speech Production with Clinical and Instrumental Evaluation.

: Hypokinetic dysarthria is a speech disorder observed in almost 90% of PD patients that can appear at any stage of the disease, usually worsening as the disease progresses. Today, speech therapy intervention in PD is seen as a possible therapeutic option to alleviate and slow down the progression of symptoms. This study aims to investigate the validity of traditional speech therapy in dysarthria with the aim of improving the quality of life of PD patients, by comparing subjective clinical assessment with objective instrumental measures (IOPI and voice analysis).

Introduction: Dysarthria is a motor speech disorder frequently associated with subcortical damage. However, the precise roles of the subcortical nuclei, particularly the basal ganglia and thalamus, in the speech production process remain poorly understood.
Methods: The present study aimed to better understand their roles by mapping neuroimaging, behavioral, and speech data obtained from subacute stroke patients with subcortical lesions.
