Objective This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third the population at some point in its applies to all age groups evaluated a setting where dysphonia would be identified managed. It intended for clinicians are likely diagnose and treat dysphonia. Purpose The primary...
Abstract Today, competencies are used in many facets of human resource management, ranging from individual selection, development, and performance management to organizational strategic planning. By incorporating into job analysis methodologies, the Office Personnel Management (OPM) has developed robust competency models that can form foundation for each these initiatives. OPM placed automated systems ensure access employees, resources professionals, managers. Shared data creates a shared...
Objectives: High-speed digital imaging (HSDI), unlike stroboscopy, is a frequency-independent visualization technique that provides detailed biomechanical assessment of vocal physiology due to increased temporal resolution. The purpose this study was investigate the clinical value HSDI compared stroboscopy across 3 disorder groups classified as epithelial, subepithelial, and neurologic disorders. Methods: Judgments vibratory features fold edge, glottal closure, phase vertical level,...
Purpose High-speed videoendoscopy (HSV) is an emerging, but barely used, endoscopy technique in the clinic to assess and diagnose voice disorders because of lack dedicated software analyze data. HSV allows quantify vocal fold oscillations by segmenting glottal area. This challenging task has been tackled various studies; however, proposed approaches are mostly limited not suitable for daily clinical routine. Method We developed a user-friendly C# that editing, motion correction,...
Standard laryngoscopic imaging techniques provide only limited two-dimensional insights into the vocal fold vibrations not taking vertical component account. However, previous experiments have shown a significant in vibration of folds. We present 3D reconstruction entire superior surface from 2D high-speed videoendoscopy via stereo triangulation. In typical camera-laser set-up structured laser light pattern is projected on folds and captured at 4000 fps. The measuring device suitable for...
Objective To examine changes in lateral and vertical vibratory motion along the anterior, middle, posterior sections of vocal folds, as a function frequency variations. Methods Absolute measurements fold surface dynamics from high‐speed videoendoscopy with custom laser endoscope were made on 23 vocally healthy adults during sustained /i:/ production at 10%, 20%, 80% pitch range. The 3D parameters amplitude (mm), maximum velocity opening/closing (mm/s), mean (mm/s) computed for folds. Linear...
Objectives: The purpose of this study was to quantify disorder-specific signature kinematic disturbances vibratory motion in adductor spasmodic dysphonia (AdSD) and muscle tension (MTD), voice a severe nature, with the use high-speed digital imaging (HSDI). A secondary hypothesis investigate sensitivity specificity features obtained from HSDI, differentiating between AdSD MTD. Methods: We used automated extraction vocal fold waveforms glottal cycle montage analysis HSDI for differential...
Purpose The aim of this study is to quantify and identify characteristic vibratory motion in typically developing prepubertal children young adults using high-speed digital imaging. Method vibrations the vocal folds were recorded from 27 (ages 5–9 years) 35 21–45 years), with high speed at 4,000 frames per second for sustained phonation. Kinematic features amplitude periodicity, time phase asymmetry, spatial symmetry, glottal gap index analyzed area waveform across mean standard deviation...

The increasing need for precise dietary monitoring across various health scenarios has led to innovations in wearable sensing technologies. However, continuously tracking food and fluid intake during daily activities can be complex. In this study, we present a machine-learning-powered smart neckband that features wireless connectivity comfortable, foldable design. Initially considered beneficial managing conditions such as diabetes obesity by facilitating control, the device's utility...
This article presents a quantitative method for assessing instantaneous and average lateral vocal-fold motion from high-speed digital imaging, with focus on developmental changes in kinematics during childhood.Vocal-fold vibrations were analyzed 28 children (aged 5-11 years) adults 21-45 without voice disorders. The following kinematic features the displacement waveforms: relative velocity-based (normalized peak opening closing velocities), acceleration-based accelerations), speed quotient,...

Motivation Human voice is generated in the larynx by two oscillating vocal folds. Owing to limited space and accessibility of larynx, endoscopic investigation actual phonatory process detail challenging. Hence biomechanics human are still not yet fully understood. Therefore, we adapt a mathematical model folds towards fold oscillations quantify gender age related differences expressed computed biomechanical parameters. Methods The dynamics visualized laryngeal high-speed videoendoscopy (4000...
