PURPOSE: This study investigates (1) the presence of frequency transmission of oscillation from an external whole-body vibration (WBV) platform to the larynx; and (2) the factors that influence this frequency transmission. METHODS: Thirty participants (mean age=22.3years) with normal voice were exposed to four frequency-intensity levels of WBV (10 Hz-10%, 10 Hz-20%, 20 Hz-10%, 20 Hz-20%) and were instructed to produce the natural vowel /a/ three times during each WBV setting...

PURPOSE: The purpose of this manuscript was twofold: to investigate how clinical voice and swallow questionnaires align with self-reports from speech/voice and swallow domains of the Unified Parkinson's Disease Rating Scale (UPDRS), and how decline in self-reported speech/voice measures predict decline in self-reported swallowing measures. METHODS: This observational, preliminary cross-sectional study included 15 people diagnosed with Idiopathic Parkinson's Disease...

METHOD: A preclinical cadaveric study followed by application on a case series of BVFP patients. After the preliminary study executed to precisely localize the optimal sites for needle insertion, a prospective interventional study was conducted on 19 subjects presenting with respiratory distress due to BVFP...

OBJECTIVES: Postoperative evaluations of patients, who undergo of transoral thyroarytenoid myoneurectomy using CO2 laser for the treatment of Adductor Spasmodic Dysphonia (ASD), reveal some residual laryngeal symptoms such as intermittent spasms, vocal effort, and stiffness in laryngeal muscles which can be identified on videolaryngo-stroboscopy (VLS) by patterns of Muscle Tension Dysphonia (MTD) and mucosal wave, and as deviations in acoustic perceptual measures. This study aims to document these vocal symptoms observed postoperatively, and most importantly highlight the need for voice therapy postoperatively and report the short-term vocal outcomes post-therapy...

OBJECTIVE: Unilateral vocal fold paralysis (UVFP) is often characterized by severe dysphonia and has a significant impact on a patient's communication in daily and vocational situations. Having a better understanding of how UVFP influences quality of life and patient experiences can help improve patient-centered care in this population. Therefore, the purpose of this study was to explore the lived experiences of patients with UVFP. METHODS: Twenty-five adults with UVFP (age range: 39-84years) participated in the study...
