Chronic voice disorder after coronavirus disease 2019 infection and its treatment using the cricothyroid visor maneuver: a case report.

Background: Regarding human coronavirus, the severe acute respiratory syndrome coronavirus 2 pandemic, the novelty of disease, and consequently the lack of studies, the etiology of dysphonia in patients with coronavirus disease 2019 is still unknown and needs to be investigated. The purpose of the current study is to investigate the effect of a new manual therapy technique, cricothyroid visor maneuver, on muscle tension dysphonia symptoms for a patient who had experienced dysphonia symptoms due to the coronavirus disease 2019 infection.

Case Presentation: A 55-year-old retired Iranian teacher who was diagnosed with muscle tension dysphonia by an otolaryngologist participated in this study.

Investigation of the effect of delayed auditory feedback and transcranial direct current stimulation (DAF-tDCS) treatment for the enhancement of speech fluency in adults who stutter: A randomized controlled trial.

Background: Stuttering is a disorder that begins in childhood and can persist into adulthood. In the present study, it was hypothesized that the combined intervention of transcranial direct current stimulation (tDCS) and Delayed Auditory Feedback (DAF) would cause greater improvement in speech fluency in comparison to the intervention with DAF alone.

Methods: A randomized, double-blind, sham-controlled clinical trial was conducted to investigate the effects of the combined intervention.

Electrophysiological correlates of stuttering severity: An ERP study.

Although a variety of theories have been proposed to explain the etiology of stuttering, the exact neurological origin of it is still uncertain. The aim of this study is to investigate the correlation between stuttering severity and ERP measures. The population of this study consisted of 12 adults with moderate, 12 adults with severe stuttering, and 12 fluent speakers as the control group.

The effect of breathing exercises combined with manual therapy on muscle tension dysphonia in traditional singers: a blinded randomized controlled trial.

Background: Muscle tension dysphonia (MTD) is common in traditional singers and can lead to serious complications, but there is inconclusive evidence about how MTD should be treated in singers as professional voice users. This study was conducted to investigate the effects of breathing exercises combined with manual therapy versus breathing exercises and manual therapy on voice quality in traditional singers suffering from MTD.

Methods: In this blinded randomized clinical trial, 60 patients with MTD were randomly allocated to four groups: (1) breathing exercises, (2) manual therapy, (3) combined intervention (CI) and (4) control.

Delayed Auditory Feedback and Transcranial Direct Current Stimulation Treatment for the Enhancement of Speech Fluency in Adults Who Stutter: Protocol for a Randomized Controlled Trial.

Background: Stuttering is a complex speech disorder that affects speech fluency. Recently, it has been shown that noninvasive brain stimulation may be useful to enhance the results of fluency interventions in adults who stutter. Delayed auditory feedback (DAF) is a method to enhance speech fluency in individuals who stutter.

A comparison of speech intonation production and perception abilities of Farsi speaking cochlear implanted and normal hearing children.

Introduction: Cochlear implant prosthesis facilitates spoken language development and speech comprehension in children with severe-profound hearing loss. However, this prosthesis is limited in encoding information about fundamental frequency and pitch that are essentially for recognition of speech prosody. The purpose of the present study is to investigate the perception and production of intonation in cochlear implant children and comparison with normal hearing children.
