The Effect of a Voice Therapy Program Using Semioccluded Vocal Tract Exercises in Women With Behavioral Dysphonia.
The Effect of a Voice Therapy Program Using Semioccluded Vocal Tract Exercises in Women With Behavioral Dysphonia.
J Voice. 2018 Jan 17;:
Authors: Ribeiro VV, de Oliveira AG, da Silva Vitor J, Siqueira LTD, Moreira PAM, Brasolotto AG, Silverio KCA
Abstract
OBJECTIVE: This study aims to propose and analyze the effect of a voice therapy program (VTP) in women with behavioral dysphonia.
MATERIALS AND METHODS: This is a controlled, blinded, and nonrandomized cohort study. Participants of this study were 22 women with behavioral dysphonia divided into two groups: G1, 11 women with behavioral dysphonia who received the VTP, and G2, 11 women with behavioral dysphonia who did not receive any intervention. Before and after 6 weeks, the outcome variables evaluated in both groups were auditory-perceptual evaluation of the global degree of vocal quality (vowel /a/ and counting), instrumental acoustic parameters, Voice-Related Quality of Life, vocal and larynx symptoms, and musculoskeletal pain. The statistical analysis used the Wilcoxon, chi-square, and Mann-Whitney tests (P < 0.05).
RESULTS: After 6 weeks, we observed a significantly higher improvement in the general degree of vocal deviation in vowels, a reduced F0 and symptom of "fatigue while talking" in G1, and an increased "shoulder" pain intensity in G2. Both groups showed improvement in the socioemotional domain of Voice-Related Quality of Life. In addition, the comparison between the groups showed a significantly greater reduction in fundamental frequency and the "voice loss" symptom in G1 compared with G2.
CONCLUSIONS: The VTP using semioccluded vocal tract exercises obtained a positive effect on voice quality, symptoms, and musculoskeletal pain in women with behavioral dysphonia. The proposal, based on the taxonomy of voice therapy, seems to have promoted a phonatory balance, muscle relaxation, and improvement in the vocal resistance of this population.

Bayesian Quantification of Sensory Reweighting in a Familial Bilateral Vestibular Disorder (DFNA9).
Bayesian Quantification of Sensory Reweighting in a Familial Bilateral Vestibular Disorder (DFNA9).
J Neurophysiol. 2017 Dec 13;:
Authors: Alberts BBGT, Selen LPJ, Verhagen WIM, Pennings RJE, Medendorp WP
Abstract
DFNA9 is a rare progressive autosomal dominantly inherited vestibulo-cochlear disorder, resulting in a homogeneous group of patients with hearing impairment and bilateral vestibular function loss. These patients suffer from a deteriorated sense of spatial orientation, leading to balance problems in darkness, especially on irregular surfaces. Both behavioral and functional imaging studies suggest that the remaining sensory cues could compensate for the loss of vestibular information. A thorough model-based quantification of this reweighting in individual patients is however missing. Here, we psychometrically examined the individual patient's sensory reweighting of these cues after complete vestibular loss. We asked a group of DFNA9 patients and healthy controls to judge the orientation (clockwise or counterclockwise relative to gravity) of a rod presented within an oriented square frame (rod-in-frame task) in three different head-on-body tilt conditions. Our results show a cyclical frame-induced bias in perceived gravity direction across a 90º-range of frame orientations. The magnitude of this bias was significantly increased in the patients compared to healthy controls. Response variability, which increased with head-on-body tilt, was also larger for the patients. Reverse engineering of the underlying signal properties, using Bayesian inference principles, suggests a reweighting of sensory signals, with an increase in visual weight of 20 to 40% in the patients. Our approach of combining psychophysics and Bayesian reverse engineering is the first to quantify the weights associated with the different sensory modalities at an individual patient level, which could make it possible to develop personal rehabilitation programs based on the patient's sensory weight distribution.

BPIFA1 Gene Expression in the Human Middle Ear Mucosa.
BPIFA1 Gene Expression in the Human Middle Ear Mucosa.
J Int Adv Otol. 2017 Dec;13(3):340-344
Authors: Hadzhiev Y, Yordanov S, Popova D, Kachakova D
Abstract
OBJECTIVE: The bactericidal/permeability-increasing, fold-containing family member A1 (BPIFA1) gene codes a secretory protein (BPIFA1), which is present in the respiratory tract mucosa, and is part of the innate immune system. This study aimed to prove that BPIFA1 gene expression exists in the human middle ear mucosa.
MATERIALS AND METHODS: In total, 32 patients participated in the study between March 2016 and September 2016. Seventeen patients had chronic otitis media with cholesteatoma (COMC) and 15 had bilateral sensorineural hearing loss (BSHL). The patients with COMC underwent radical mastoidectomy with cholesteatoma removal and those with BSHL underwent cochlear implantation. Part of the processus mastoideus mucosa was examined for BPIFA1 gene expression and the two groups were compared.
RESULTS: For the first time, BPIFA1 gene expression was examined in the mucosa of the human middle ear, and it was verified in 100% (n=32) of the participants. We confirmed that there is a difference in the BPIFA1 expression in 83.33% of the patients with COMC compared to the patients with BSHL but this difference was not statistically significant (p=0.947; probably due to the low number of participants in this group).
CONCLUSION: It is highly likely that the BPIFA1 protein participates in the non-specific immune defense of the middle ear and is relevant to the pathogenesis of the inflammatory diseases of the middle ear.

Auditory Training With Frequent Communication Partners.
J Speech Lang Hear Res. 2016 Aug 01;59(4):871-5
Authors: Tye-Murray N, Spehar B, Sommers M, Barcroft J
Abstract
PURPOSE: Individuals with hearing loss engage in auditory training to improve their speech recognition. They typically practice listening to utterances spoken by unfamiliar talkers but never to utterances spoken by their most frequent communication partner (FCP)-speech they most likely desire to recognize-under the assumption that familiarity with the FCP's speech limits potential gains. This study determined whether auditory training with the speech of an individual's FCP, in this case their spouse, would lead to enhanced recognition of their spouse's speech.
METHOD: Ten couples completed a 6-week computerized auditory training program in which the spouse recorded the stimuli and the participant (partner with hearing loss) completed auditory training that presented recordings of their spouse.
RESULTS: Training led participants to better discriminate their FCP's speech. Responses on the Client Oriented Scale of Improvement (Dillon, James, & Ginis, 1997) indicated subjectively that training reduced participants' communication difficulties. Peformance on a word identification task did not change.
CONCLUSIONS: Results suggest that auditory training might improve the ability of older participants with hearing loss to recognize the speech of their spouse and might improve communication interactions between couples. The results support a task-appropriate processing framework of learning, which assumes that human learning depends on the degree of similarity between training tasks and desired outcomes.

Audiologist Practices: Parent Hearing Aid Education and Support.
J Am Acad Audiol. 2016 Apr;27(4):324-32
Authors: Meibos A, Muñoz K, White K, Preston E, Pitt C, Twohig M
Abstract
BACKGROUND: Early identification of hearing loss has led to routine fitting of hearing aids in infants and young children. Amplification provides opportunities to optimize child development, although it also introduces challenges for parents to navigate. Audiologists have a central role in providing parents with support to achieve effective management strategies and habits.
PURPOSE: The purpose of this study was to explore current practices of pediatric audiologists who work with children birth to 5 yr of age, regarding their support of parent learning in achieving effective hearing aid management, identify existing gaps in service delivery, and to determine if audiologists were receptive to receiving training related to effective approaches to provide counseling and support to parents.
RESEARCH DESIGN: A cross-sectional, population-based survey was used.
STUDY SAMPLE: Three hundred and forty-nine surveys were analyzed from pediatric audiologists who provided services to children birth to 5 yr of age. Responses were received from 22 states in the United States.
DATA COLLECTION AND ANALYSIS: Responses were collected through the mail and online. Descriptive statistics were used to analyze the information.
RESULTS: More than half (61%) of the audiologists in the study had been providing pediatric hearing aid services to children birth to 5 yr of age for >10 yr. Of the audiologists who reported monitoring hours of hearing aid use, the majority reported that they used data logging (90%). More than half of the audiologists (57%) who shared data logging with parents reported that they encountered defensiveness from parents when addressing hearing aid use. Information and skills that were not routinely provided by one-third to one-half of the audiologists included the following: how to get access to loaner hearing aids (30%), available hearing aid options/accessories (33%), available financial assistance (36%), how to teach hearing aid management to other caregivers (38%), how to do hearing aid maintenance (44%), and how to do a Ling 6 sound check (52%). Many audiologists reported they did not frequently collaborate with speech-language pathologists (48%), early interventionists (47%), or physicians (68%). More than half of the audiologists indicated a desire for more training in counseling skills, for all 14 items queried, to support parents with hearing aid management (53-79%), regardless of their previous training experience.
CONCLUSIONS: For young children with hearing loss to achieve optimal benefit from auditory experiences for speech and language development, they need evidence-based, comprehensive, and coordinated hearing aid management. Audiologists have an important role for teaching information and skills related to hearing aids, supporting parent learning, and collaborating with other providers. Pediatric audiologists in this study recognized and desired the need for further training in counseling skills that can better prepare them to meet the emotional needs of parents in the hearing aid management process.
