Several studies have shown a high prevalence of voice disorders among teachers. However, it is difficult to establish comparisons among the results found given the great variability among criteria and symptoms used to define the presence of vocal alteration, in addition to the variations in the composition of the populations studied (age, gender, origin, working schedule, profession, among othe...

Systems that automatically detect voice pathologies are usually trained with recordings belonging to population of all ages. However such an approach might be inadequate because of the acoustic variations in the voice caused by the natural aging process. In top of that, elder voices present some perturbations in quality similar to those related to voice disorders, which make the detection of pa...

Speech Pathologists use behavioural voice therapy to treat a wide variety of patients who suffer from dysphonia. In all cases these voice disorders can result in severe disability, distress and handicap as well as economic hardship and psychological trauma for the individual) [1-3] reported on the evidence base for primary speech/voice therapy intervention in five types of voice disorders. : Fu...

Advances in neuroscience have led to an expanded and improved understanding of neurobiological changes associated with rehabilitation and exercise in Parkinson's disease (PD). This knowledge has led to a direct clinical impact of increased referral for early and continuous exercise programs for individuals with PD (physical, occupational, speech therapy and general exercise programs) and an inc...

The role of the speech-language pathologist (SLP) has developed considerably over the past 20 years given the medical and technological advances in life-sustaining procedures. Children born with congenital, surgical, or "medically fragile" conditions become mainstreamed into regular school-based settings, thus extending the traditional role of the treating SLP and multidisciplinary team. Unders...

The simultaneous assessment of the status of the glottis opening and the position of the larynx can be beneficial for the diagnosis of disorders of voice production and swallowing. The method presented here makes use of a time-multiplex algorithm for the measurement of space-resolved transfer impedances through the larynx. The fast sequence of measurements allows a quasi simultaneous assessment...

INTRODUCTION Dysphonia is the main symptom of the disorders of oral communication. However, voice disorders also present with other symptoms such as difficulty in maintaining the voice (asthenia), vocal fatigue, variation in habitual vocal fundamental frequency, hoarseness, lack of vocal volume and projection, loss of vocal efficiency, and weakness when speaking. There are several proposals for...

When children come into contact with their peers in pre-school institutions, conflicts for domination begin. The children often shout and speak outside their register. This behavior negatively affects the proper development of their phonation mechanisms. The purpose of the present work is to determine the differences between the vocal characteristics of a group of children with vocal disorders ...

This study compared the frequency and effects of voice symptoms in teachers to a group of individuals employed in other occupations. Teachers were more likely to report having a voice problem (15 vs. 6%), having 10 specific voice symptoms, and having 5 symptoms of physical discomfort. They averaged almost 2 symptoms compared with none for nonteachers. Likewise, teachers were more likely to perc...

background: one third of patients with parkinson’s disease (pd) have mentioned “dysphonia” as their most debilitating communication deficit. patient-based measurements, such as voice handicap index (vhi) add necessary supplementary information to clinical and physiological assessment. there are a few studies about relation between vhi and disease severity in pd, although none of them showed any...
