Expiratory Muscle Strength Training in patients After Total Laryngectomy; A Feasibility Pilot Study.

Objectives: Expiratory muscle strength training (EMST) is a threshold based device-driven treatment for improving expiratory pressure. EMST proved to be effective in different patient groups to improve cough function. To date, EMST has not been tested in the total laryngectomy population (TL).

Quantifying Laryngopharyngeal Reflux in Singers: Perceptual and Objective Findings.

This study examines the relationship between laryngopharyngeal reflux (LPR) symptoms and oropharyngeal pH levels in singers. We hypothesized that reported symptoms would correlate with objective measures of pH levels from the oropharynx, including the number and total duration of reflux episodes. Twenty professional/semiprofessional singers completed the Reflux Symptom Index (RSI) and underwent oropharyngeal pH monitoring.

Computational Modelling of Cough Function and Airway Penetrant Behavior in Patients with Disorders of Laryngeal Function.

Objective/hypothesis: Patients with laryngeal disorders often exhibit changes to cough function contributing to aspiration episodes. Two primary cough variables (peak cough flow: PCF and compression phase duration: CPD) were examined within a biomechanical model to determine their impact on characteristics that impact airway compromise.

Study Design: Computational study.

Effects of expiratory muscle strength training on maximal respiratory pressure and swallow-related quality of life in individuals with multiple sclerosis.

Background: Weakening and dyscoordination of expiratory muscles in multiple sclerosis (MS) can impair respiratory and swallow function.

Objective: The objective of this paper is to test a novel expiratory muscle strength training (EMST) device on expiratory pressure, swallow function, and swallow-related quality-of-life (SWAL-QOL) in individuals with MS.

Methods: Participants with MS were randomized to a five-week breathing practice of either positive pressure load (EMST) or near-zero pressure (sham).

Assessment of Airway Defenses in the Neurologically Impaired Patient.

Impairment of cough and swallow is a potential consequence of neurological dysfunction that places affected patients at increased risk for respiratory compromise and death. Nurses are critical to early identification and frequent screening of airway defense mechanisms to reduce aspiration risk and improve clinical outcomes in patients with neurological impairment.

Objective: To examine relations between peak expiratory (cough) airflow rate and swallowing symptom severity in participants with Parkinson disease (PD).

Design: Cross-sectional study.

Setting: Outpatient radiology clinic at an acute care hospital.

Behavior Assessment Battery: A Pilot Study of the Affective, Behavioral, and Cognitive Correlates Surrounding Spasmodic Dysphonia.

Objective/hypothesis: This study investigates if adults with adductor spasmodic dysphonia (ADSD) report to experience anxiety and voice problems in particular situations, indicate the presence of negative speech-associated attitude, and/or the use of coping behaviors, by means of the Behavior Assessment Battery (BAB) modified for voice.

Methods: Thirty-two participants with ADSD and 32 adults without a voice disorder participated in this study. Each person completed four different BAB-Voice subtests.

Management of Dysphagia Pre- and Postoperatively in a Case of Eagle's Syndrome.

Eagle's syndrome (ES) is rare condition, most frequently described within the context of case study presentation. ES results from elongation of the styloid process, contributing to symptoms such as globus sensation in the throat, as well as pain localized to the ear, neck, face, or tongue. Additional symptoms can include hypersalivation, change in vocal quality, submandibular swelling, and dysphagia.

The role of the speech-language pathologist in the schools for the treatment of voice disorders: working within the framework of the individuals with disabilities education improvement act.

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. Understanding the impact of associated voice disorders on educational performance requires dissemination of additional and important information, as eligibility decisions for students in school-based settings must be made within the framework of the federal legislation and regulations governing the provision of services for students with disabilities.

A model for treating voice disorders in school-age children within a video gaming environment.

Objective: Clinicians use a variety of approaches to motivate children with hyperfunctional voice disorders to comply with voice therapy in a therapeutic session and improve the motivation of children to practice home-based exercises. Utilization of current entertainment technology in such approaches may improve participation and motivation in voice therapy. The purpose of this study is to test the feasibility of using an entertainment video game as a therapy device.

Tutorial on maximum inspiratory and expiratory mouth pressures in individuals with idiopathic Parkinson disease (IPD) and the preliminary results of an expiratory muscle strength training program.

Respiratory symptoms are recognized as sequelae of motor dysfunction in idiopathic Parkinson's disease (IPD) and these symptoms have the potential to cause problems with swallow, cough, voice and speech. Specifically, maneuvers that require rapid activation and coordination of upper airway and chest wall musculature become progressively impaired as motor dysfunction progresses during the natural course of the disease. This study reports on the maximum inspiratory and expiratory pressures produced by 28 participants (average age 64) diagnosed with moderate to severe IPD (average stage 2.

Voice handicap index results for older patients with adductor spasmodic dysphonia.

Adductor spasmodic dysphonia (ADSD) adversely affects a speaker's ability to effectively communicate. For many individuals suffering with ADSD, botulinum toxin (Botox) is the chosen treatment to remediate the symptoms. Although Botox's effects on symptom remediation have been examined before, patient perception of improvement post-Botox has been examined less frequently.

Treating voice disorders in the school-based setting: working within the framework of IDEA.

The role of the speech-language pathologist (SLP) has developed considerably over the last 10 years given the medical and technological advances in lifesustaining procedures. Over time, children born with congenital, surgical, or "medically fragile" conditions hav become mainstreamed into regular school-based settings, thus extending the traditional role of the SLP and multidisciplinary team. Understanding the impact of these voice disorders on the child's educational performance has been a struggle for many clinicians because the eligibility decisions for students in school-based settings must be made within the framework of federal legislation and regulations governing the provision of services for students with disabilities.

Laryngeal structure and function in the pediatric larynx: clinical applications.

This article presents an overview of the normal anatomy and physiology of the pediatric larynx, followed by some examples of pediatric voice disorders that were chosen to exemplify the alterations to the laryngeal anatomy and the subsequent modifications to laryngeal function. Vocal fold nodules are primarily reviewed due to their high incidence in the pediatric population. Three other disorders, including laryngeal hyperfunction, unilateral vocal fold paralysis, are discussed because of their more common occurrence and the uniqueness of their etiology and intervention, particularly for the case of bilateral abductor vocal fold paralysis.

An adaptive driver and real-time deformation algorithm for visualization of high-density lung models.

Technological advances in Augmented Reality (AR) and extraction of 3D patient specific medical data led to the creation of medical visualization using AR environments, in which the 3D data is registered and synchronized with the position of the patient. One of the challenges in such visualization environments is maintaining an accurate shape of the 3D data for self-deformable models such as lungs. An accurate deformation of lung model with 3D visualization may significantly increase the teaching and diagnosing ability of physicians.

Inspiratory muscle strength training with behavioral therapy in a case of a rower with presumed exercise-induced paradoxical vocal-fold dysfunction.

Paradoxical vocal fold dysfunction (PVFD) with high effort exercise can result in disruptions to ventilation, dyspnea, inspiratory stridor, elevated heart rate, and syncope. This single subject study experimentally tested an inspiratory muscle strength training (IMST) program with behavioral therapy on a 15-year-old male crew member. Outcome variables were maximum inspiratory pressure (MIP), and dyspnea ratings.

Inspiratory pressure threshold training for upper airway limitation: a case of bilateral abductor vocal fold paralysis.

A single subject design was used to determine if pressure threshold training strengthens the inspiratory muscles in a subject with a limited glottal airway as well as diminish dyspnea and improve parameters of speech. The subject was a 19-year-old woman whose glottal airway was limited due to bilateral abductor vocal fold paralysis following a thyroidectomy. A 5-week inspiratory muscle strength-training program was implemented using a pressure-threshold trainer to strengthen the inspiratory muscles with the intent of enabling the generation of higher inspiratory pressures.
