Active clinical trials for "Voice Disorders"

In this prospective study we extracted acoustic parameters using PRAAT from patient's attempt to phonate during the clinical evaluation using a digital smart device. From these parameters we attempted (1) to define which of the PRAAT acoustic features best help to discriminate patients with dysphagia (2) to develop algorithms using sophisticated ML techniques that best classify those i) with dysphagia and those ii ) at high risk of respiratory complications due to poor cough force.

This study investigates in patients whose primary complaint is either neck pain and/or a voice disorder , if there are any correlations between subjective neck and voice symptoms according to Neck Disability Index (NDI) and Voice Handicap Index (VHI). NDI and VHI questionnaire results for voice disordered patients will be retrieved from the data base of the Department of Phoniatrics and Speech Pathology, University Hospital Zurich. Neck pain patient questionnaire data will be retrieved from an ongoing study. The agreement between subjective neck handicap (NDI) and voice handicap (VHI) will be statistically analysed.

Evaluation of the effect of chronic rhinosinusitis on the laryngeal mucosa and voice quality in children. This is important to know factors affecting voice disorders

Singers are over-represented in phoniatric consultation; they present increased risk of developing voice disorders. They represent a specific population among phoniatric patients (specific singing-voice complaints, increased sensitivity to voice). Singing-voice disorder is called dysodia in the same way as dysphonia, which refers to speaking-voice disorders. The diagnosis of dysodia is made after a laryngeal examination and a voice assessment to identify patient's speech and singing difficulties. Most studies on prevalence of voice disorders in singers come from the American continent. Very few descriptions of this population have been made in France. Voice assessment of dysodic singers includes aerodynamic voice measurements. The use of aerodynamic measurements for the diagnosis of voice pathologies is now widely demonstrated. These parameters include measurements of estimated subglottal pressure (ESGP), phonation threshold pressure (PTP) (minimum pressure to initiate a sound) and oral airflow (OAF). They depend on the level of training of singers and the type of vocal dysfunction. Aerodynamic behaviours of dysodic singers have not yet been described, although they can help to better identify the singer's vocal difficulties and could be essential parameters for targeting more precisely rehabilitation exercises proposed in voice therapy. This study aims to describe the characteristics of a French population of singers consulting in phoniatrics and their aerodynamic behaviours. Do the singers' aerodynamic parameters (pressure, flow) reflect the dysfunctions in singing voice? Based on results of the literature on speaking and singing non-pathological voice, the investigators hypothesize that during voice assessment, ESGP values will be increased and OAF ones will be decreased over the entire vocal range of the singer in case of voice pathology.

This study examines the presence, severity and natural history of dysphagia and dysphonia in the post-extubation and severely unwell COVID-19 patient.
