introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

Working memory deficit in schizophrenia is a core cognitive feature of the disorder and is reliably associated with abnormalities of the prefrontal circuitry. Working memory deficits are also associated with impaired social functioning and present a major obstacle toward successful rehabilitation in schizophrenia. Although the role of prefrontal cortex in working memory has been extensively inv...

Aim of this investigation was to analyse the voice in a group of 20 patients submitted to supracricoid partial laryngectomy (cricohyoidopexy, sparing two arytenoids) by the Multi Dimensional Voice Programme acoustic analysis system. Results revealed the following sound characteristics: high rate of noise, lack of periodic component of the signal, high rate of segments with no sound signal, voca...

To find out the incidence of various types of benign mucosal lesions of the vocal fold causing hoarseness; To review the role of demographic ,etiological and risk factors in relation to the benign mucosal lesions of the vocal fold. It was a Prospective, observational study. Patients with hoarseness, presenting the ENT and Head-Neck surgery department of a tertiary-care hospital from October 201...

After total laryngectomy, the placement of a tracheoesophageal (TE) puncture offers the possibility to gain a new voice. However, the produced TE speech is known to have a lower quality and intelligibility. The goal of this paper is to identify and quantify the acoustic artefacts in TE speech. The advantage of this study is two-fold. First, the proposed measures can be used by speech therapists...

Background: rehabilitation of individuals with total laryngectomy. Aim: to correlate the voice and speech proficiency of individuals with total laryngectomy, users of tracheoesophageal, prosthesis with the intraluminal pharyngoesophageal transition pressure at rest and during phonation. Method: twelve individuals with total laryngectomy and with tracheoesophageal voice, users of speech prosthes...

Total laryngectomy or laryngopharyngectomy remains the procedure of choice for advanced-stage (UICC T3 and T4) laryngeal carcinoma around the world despite advances in conservative laryngeal surgery and radiotherapy. However, it has profound effects on respiration and deglutition, in addition to the most disabling effect-the loss of verbal communication. Successful voice restoration can be atta...

This paper develops, simulates and experimentally evaluates a novel method based on non-contact low frequency ultrasound which can determine, from airborne reflection, whether the lips of a subject are open or closed. The method is capable of accurately distinguishing between open and closed lip states through the use of a low complexity detection algorithm, and is highly robust to interfering ...

BACKGROUND The purpose of this study was to present our findings on the impact of the Blom tracheotomy tube with speech inner cannula on voice production abilities and speech intelligibility scores of ventilator-dependent patients requiring a fully inflated tracheotomy tube cuff. METHODS Prospective single group case-series design permitted consecutive accrual of 23 adult inpatients from acut...
