Validation of the Spanish Version of the Voice-Related Quality of Life Questionnaire: Psychometric Properties and Clinical Applications.

Introduction: The present study aimed to validate the Voice-Related Quality of Life (V-RQOL), vocal self-assessment questionnaire for Spanish.

Methods: The validation and psychometric properties were developed according to the criteria of the Scientific Advisory Committee of Medical Outcomes Trust (SAC). The Spanish translation for linguistic and cultural adaptation of the V-RQOL was used.

Gut Immunomodulation with Vedolizumab prior to Allogeneic Hematopoietic Stem Cell Transplantation in Pediatric Patients with Inflammatory Bowel Disease.

Inborn errors of immunity (IEI) are often associated with inflammatory bowel disease (IBD). IEI can be corrected by allogeneic hematopoietic stem cell transplantation (HSCT); however, peritransplantation intestinal inflammation may increase the risk of gut graft-versus-host disease (GVHD). Vedolizumab inhibits the homing of lymphocytes to the intestine and may attenuate gut GVHD, yet its role in preventing GVHD in pediatric patients with IEI-associated IBD has not been studied.

Remote Voice Therapy With an Oscillatory Positive Expiratory Pressure Device in Subjects With Vocal Fatigue: A Randomized Controlled Trial.

Purpose: The present study aimed at assessing the efficacy of remote voice therapy (telepractice) implemented with Shaker Medic Plus device in subjects with vocal fatigue.

Method: Thirty-six participants were initially enrolled in this study. Twenty-four participants with vocal fatigue were finally randomly assigned to one of two treatment groups: (a) voice treatment with Shaker Medic Plus device plus vocal hygiene program ( = 12) and (b) voice treatment with water resistance therapy (WRT) plus vocal hygiene program ( = 12).

HO Concentration in Exhaled Breath Condensate Increases After Phonotrauma: A Promise of Noninvasive Monitoring?

Purpose: The present study was designed to observe the concentration of hydrogen peroxide (HO) in exhaled breath condensate (EBC) after induced phonotrauma.

Methods: Thirty-five participants were randomly assigned to one of two conditions (1) Vocal demand and (2) Control. Participants in the experimental group (vocal demand) were asked to read aloud some texts during 1 hour, at 85-90 dB.

Voice Performance Chart: A Pedagogical Tool to Enhance Vocal Expressive Ability in Acting Students.

The purpose of the present study was to explore the effectiveness of the Voice Performance Chart (VPCH) as a pedagogical training tool to enhance vocal expressive ability of 1st year acting students. Forty recorded audio samples were perceptually assessed by six blinded raters, using a five-points Likert scale for each of the dependent variables observed. Results showed that loudness, pitch, and speech rate variations significantly differ when comparing the vocal condition before and after a 11 weeks training period.

Tissue Mobilization During Double Source of Vibration Semioccluded Vocal Tract Exercises: A Neck and Face Surface Acceleration Study.

Purpose This study primarily aimed at observing the possible tissue mobilization on facial, neck, and chest tissues caused by different double source of vibration semioccluded vocal tract exercises (DSV-SOVTEs). Another goal was to inspect the degree of self-perceived sensation of a massage-like sensation. Method Fifty-five participants engaged in a set of several DSV-SOVTEs: (a) phonation with a silicone tube submerged 2 and 8 cm below water surface, (b) Acapella Choice device, (c) lip trills, and (d) tongue trills.

Translation and cross-cultural adaptation of the Chilean Version of the Voice Activity and Participation Profile - VAPP.

Purpose: The present study aimed to obtain the cross-culturally-adapted Chilean version of the voice activity and participation profile - VAPP.

Methods: The process began a with translation of the original English version of the VAPP instrument into Spanish, carried out by two bilingual speech-language pathologists (SLP), followed by a back-translation from a third SLP who was unbiased by the previous stages. A committee of 5 SLP with experience in the area of voice compared the original version, the back translation, and the translated version, seeking divergences and discrepancies between the three versions.

How Do Tube Diameter and Vocal Tract Configuration Affect Oral Pressure Oscillation Characteristics Caused by Bubbling During Water Resistance Therapy?

Purpose: The present study aimed at observing the effect of tube diameter and vocal tract configuration on frequency, amplitude, and regularity of Poral oscillation caused by bubbling during water resistance therapy (WRT). A secondary objective was to examine the degree of self-perceived sensation of massage-like effect produced by bubbles during WRT.

Methods: Forty-two participants were included in this study.

Aerodynamic Characteristics of Growl Voice and Reinforced Falsetto in Metal Singing.

Objectives: The present study aimed to assess the aerodynamic characteristics of vocally healthy metal singers when producing growl voice or reinforced falsetto.

Methods: Fifty-four participants (metal singers) were initially enrolled in this study, with 23 meeting the inclusion criteria. Sixteen participants performed growl voice and seven performed reinforced falsetto as a voice resource during metal singing.
