Background: Based on stakeholder conversations, speech and language therapists have anecdotally observed cases of dysphagia with suspected laryngeal hypersensitivity. These presentations have been coined as 'muscle tension dysphagia' often with concurrent laryngeal sensitivity symptoms. However, the role of laryngeal hypersensitivity in dysphagia…

Purpose: This study examined the discriminative ability of acoustic indices of vocal hyperfunction combining smoothed cepstral peak prominence (CPPS) and relative fundamental frequency (RFF). Method: Demographic, CPPS, and RFF parameters were entered into logistic regression models trained on two 1:1 case-control groups: individuals with and…

Objective: Currently, no clinically feasible objective measures exist that are specific to the signs of adductor laryngeal dystonia (LD), deterring effective diagnosis and treatment. This project sought to establish concurrent validity of a new automated acoustic outcome measure, designed to be specific to adductor laryngeal dystonia (AdLD): the…

Purpose: This study examined the relationship between voice quality and glottal geometry dynamics in patients with adductor spasmodic dysphonia (ADSD). Method: An objective computer vision and machine learning system was developed to extract glottal geometry dynamics from nasolaryngoscopic video recordings for 78 patients with ADSD. General…

Purpose: High-speed videoendoscopy (HSV) is an emerging, but barely used, endoscopy technique in the clinic to assess and diagnose voice disorders because of the lack of dedicated software to analyze the data. HSV allows to quantify the vocal fold oscillations by segmenting the glottal area. This challenging task has been tackled by various…

Background: Published best-practice guidelines and standardized protocols for voice assessment recommend multidisciplinary evaluation utilizing a comprehensive range of clinical measures. Previous studies report variations in assessment practices when compared with these guidelines. Aims: To provide an up-to-date evaluation of current global…

Purpose: The purpose of this study was to investigate the characteristics of diplophonia using an auditory perception and multimodal simultaneous examination, which included sound waveform analysis, electroglottography (EGG), digital kymography (DKG), and 2-dimensional scanning digital kymography (2D DKG). Additionally, we compared the diagnostic…

Purpose: The purpose of this study was to use objective measures of glottal gap, bowing, and supraglottic compression from selected images of laryngoscopic examinations from adults over 60 years of age with voice complaints and signs of aging to test current hypotheses on whether degree of severity impacts treatment recommendations and potential…

Purpose: Vocal fold nodules (VNs) are bilateral, symmetrical, callous-like lesions secondary to phonotrauma and possibly related to specific personality traits. This case-control study examined the relation between personality and VNs in children within the context of the Trait Theory of VNs. Method: Parents of children with VNs (N = 39, M = 7.43,…
