Low-Cost Joystick for Pediatric Respiratory Exercises.

The use of body signals for health care applications has become ubiquitous in the last decade. One utilization of such measurements is the monitoring of respiratory flow for physiotherapy assistance. This application is based on relative flow measures which can rely on inexpensive sensors.

Vocal Tract Discomfort Scale: Validation of the Argentine Version.

Objective: The objective of this study was to validate the Vocal Tract Discomfort Scale (VTD) Argentine version.

Study Design: Nonrandomized, cross-sectional prospective study with control group.

Material And Methods: The VTD Scale was culturally and linguistically adapted to Argentinian Spanish according to the recommended requirements of translation, closely observing the methodology that was suggested (translation, summary, review and back-translation).

High-speed Videolaryngoscopy: Quantitative Parameters of Glottal Area Waveforms and High-speed Kymography in Healthy Individuals.

Objectives: We conducted a study to obtain quantitative parameters of the vocal dynamic using high-speed videolaryngoscopy and to characterize the vocal fold vibration pattern of healthy individuals by analyzing glottal area waveforms and high-speed kymography.

Methods: Laryngeal images of 45 healthy individuals were captured using high-speed videolaryngoscopy. The open and speed quotients of the glottal area waveforms and high-speed kymography were obtained and statistically analyzed according to the gender of each individual.

Improvement of vocal pathologies diagnosis using high-speed videolaryngoscopy.

Introduction The study of the dynamic properties of vocal fold vibration is important for understanding the vocal production mechanism and the impact of organic and functional changes. The advent of high-speed videolaryngoscopy (HSV) has provided the possibility of seeing the real cycle of vocal fold vibration in detail through high sampling rate of successive frames and adequate spatial resolution. Objective To describe the technique, advantages, and limitations of using HSV and digital videokymography in the diagnosis of vocal pathologies.

Cognitive Vocal Program applied to individuals with signals presbylarynx: preliminary results.

Purpose: To propose and verify the feasibility of a vocal program intervention in patients with presbylarynx signs with or without vocal complaints.

Method: Among 20 elder participants of the current research, 3 female patients with median age of 67 years were chosen for the pilot study. Laryngological examination, vocal recording with CAPE-V (Consensus Auditory-Perceptual Evaluation of Voice) protocol, and Screening Protocol of Risk of Dysphonia (SPRD) were conducted before and after the program intervention.

Graphical evaluation of vocal fold vibratory patterns by high-speed videolaryngoscopy.

Objective: To characterize the voice and vocal fold function of an individual, it is essential to evaluate vocal fold vibration. The most widely used method for this purpose has been videolaryngoscopy.

Methods: This article proposes a digital image processing algorithm to estimate the glottal area (ie, the space between the vocal folds) and produce graphs of the opening and closing phases of the glottal cycle.

High-speed kymography identifies the immediate effects of voiced vibration in healthy vocal folds.

Introduction:  The effects of voiced vibration technique can be assessed by laryngeal imaging. Kymographic images derived from high-speed videoendoscopy allow actual visualization of vocal folds vibration.

Purpose:  The aim of this study is to identify the immediate effects of the voiced vibration technique in healthy vocal folds using high-speed digital laryngeal imaging.

Parameters acoustic and high-speed kymography identified effects of voiced vibration and vocal fry exercises.

Purpose: To identify the immediate effects of voiced vibration and vocal fry exercises on healthy subjects by means of acoustic parameters and high-speed kymography.

Methods: Thirty healthy subjects (18 women and 12 men, aged from 19 to 45 years old) participated in this study. The voices were recorded at the range of 44.
