Filter by:1. The first objective of this research is to investigate the immediate effects of three semi-occluded vocal tract (SOVT) exercises (straw phonation in air, straw phonation in 2cm water, and straw phonation in 5cm water) on (supra)glottic activity of vocally healthy participants and patients with voice disorders (dysphonia) visualized with laryngovideostroboscopy. Participants will receive a flexible laryngovideostroboscopy, both during normal phonation and during the specific SOVT exercise. These videos will be randomly and blindly evaluated by two experts using the Voice-Vibratory Assessment with Laryngeal Imaging (VALI) rating form (Poburka et al., 2017). Researchers will compare the effects of these SOVT exercises on the (supra)glottic activity with the effects found in a control group producing /u/ phonation, using a randomized controlled trial. 2. The second objective of this research is to investigate the short- and long-term effects of the three SOVT therapy approaches on the (supra)glottic activity, voice quality and self-report of patients with voice disorders (dysphonia). Participants will receive a short-term intensive therapy with the specific SOVT exercise across four weeks. Immediately after the therapy program and at 1 and 3 months follow-up, the voice of the participants will be re-evaluated.
The aim is to gain information about vocal hygiene knowledge level, phonotrauma behavior frequency, voice-related quality of life, and voice handicap index scores in children diagnosed with ADHD aged 8 to 11, through inter-group comparisons of scale and questionnaire data between children diagnosed with ADHD and control group participants aged 8 to 11.
The aim of the study is to translate and culturally adapt the Turkish version of the EASE (EASE-TR) scale and investigate its validity and reliability.
The goal of this clinical trial is to determine and compare the effects of different voice therapy programs in children with vocal fold nodules. Vocal fold nodules are non-cancerous growths on the vocal folds which cause hoarseness. The main questions this trial aims to answer are: - What are the short-term effects of the new voice therapy program 'straw phonation' and a more traditional 'resonant voice therapy' program on (a) the vocal quality, (b) the size of the growths on the vocal folds, and (c) the overall functioning in children with vocal fold nodules? During straw phonation exercises, you make sound through a drinking straw. During resonant voice therapy exercises or 'humming', you make an 'm' sound as you breathe out. - What are the long-term effects of these voice therapy programs? Participants will receive a short-term intensive voice therapy program of four days. The researchers will compare the straw phonation group, resonant voice therapy group and control group to see if voice therapy works well in treating children with vocal fold nodules. The researchers hypothesize that straw phonation will have better results than resonant voice therapy. Straw phonation exercises are easier for children because they use an external tool (the straw) and less self-correction is needed.
The goal of this clinical trial is to learn about voice function before and 3 hours after administration of first generation over-the-counter antihistamine in individuals who have been medically diagnosed with allergies and routinely take over-the-counter (OTC) antihistamines for allergy symptoms. The main questions are: 1. Do first generation OTC antihistamines make voice function worse as measured via voice acoustic and aerodynamic measures? It is hypothesized that all objectives measures will reflect a negative change in voice function. 2. Do first generation OTC antihistamines make voice function worse as measured via participant and researcher perceptual measures? It is hypothesized that participants will rate their vocal function as more effortful after taking the antihistamine and researchers will rate voice quality as worse. Participants ages 18-35 who have been diagnosed with allergies, are free of laryngeal pathology, and meet inclusion criteria will be consented. Participation in the study involves a pretrial visit and one day of data collection. The initial visit will obtain informed consent and train the trial measures. The 2nd day involves determination of systemic hydration (<1.02 g/ml), administration of the OTC antihistamine (Chlor-Trimeton), and measures taken at baseline and 3 hours after antihistamine administration. This antihistamine was selected for its lower sedation and anticholinergic effects than its other first-generation options. Each participant will take one, 12mg tablet. Onset action time for this antihistamine is 3 hours. Participants will be given water to consume during the 3 hour wait for the 2nd data time point to maintain hydration. Measures include routine clinical perceptual, acoustic, aerodynamic, and laryngeal imaging measures.
Severe acute respiratory syndrome coronavirus-2 transmits through droplets; thus, oral, nasal, and conjunctival mucosas are related to contamination, and wearing personal protective equipment (PPE) is strongly suggested. Several communication problems between the patient and healthcare workers related to PPE use are reported. In this study, investigators aimed to investigate changes in the acoustic parameters of speech sounds when different PPE are used.
This study will investigate if the performance on the Montreal Cognitive Assessment (MoCA) is associated or predictive of the outcomes in voice, swallowing or upper airway therapy in the older laryngology treatment seeking patients. The relationship between the scores of MoCA and parameters in therapy will be analyzed. The outcomes of this study could potentially impact how investigators determine candidacy for therapy and develop patient treatment plans to meet their needs. This is a collaborative study with Emory Voice Center and the NYU Voice Center.
Study investigators have completed a study testing laryngopharyngeal sensation at specific laryngopharyngeal subsites using a novel buckling force aesthesiometer in a series of 22 healthy adults at this institution. Investigators would like to use the same device apparatus to evaluate laryngopharyngeal sensation in patients with laryngopharyngeal disorders, such as adductor spasmodic dysphonia. This study will use a tested laryngopharyngeal aesthesiometer to examine laryngeal sensation using calibrated tactile stimuli to determine differences in somatotopic perceptual strength maps of laryngopharyngeal structures between patients with laryngopharyngeal disorders and healthy controls.
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.
Speech and voice disorders are observed in almost 90% of patients with PD during their course of illness. Reduced voice pitch inflections or monotone speech, reduced vocal loudness, prosody disorders, the imprecise articulation of the consonants, hoarseness, and breathy voice is also observed in patients with PD; these symptoms often lead to reduced speech intelligibility. The aim of this study will to investigate the possible changes in the voice and speech features in people with PD after a combined speech and music therapy using Telerehabilitation.
