Filter by:Adductory spasmodic dysphonia (AdSD) is a rare condition characterised by irregular and uncontrolled voice interruptions, most commonly affecting women around the age of 45. The diagnosis is clinical and usually requires evaluation by several specialists. The exact cause is not known, but a disturbance of the motor system is hypothesised, probably related to various causes such as loss of cortical inhibition or problems with sensory input. Neuroimaging studies have shown hyperactivity in various brain regions during speech production in patients with AdSD, but it is still unclear whether this hyperactivity is due to a malfunction of auditory and somatosensory feedback or an impairment of motor programming. Recent research indicates that patients with AdSD show excessive muscle activation during phonation, probably due to abnormal processing of auditory feedback. This suggests that intervention in the auditory system may offer new treatment opportunities. The proposed study aims to describe the acoustic, auditory-perceptual and subjective voice and speech changes in AdSD subjects during the Quick-Lombard Test (LT), a test that assesses vocal response under noisy conditions.
This research study is investigating whether people with Alzheimer's disease experience more changes to voice and swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe Alzheimer's Disease is high (85-93%) and voice is also often negatively impacted by Alzheimer's disease. The overall objective of this study is to evaluate the voice and swallowing function of adults with and without Alzheimer's disease. The investigators will also be involving the primary caregivers of individuals with Alzheimer's that are enrolled in the study to better understand the impact of voice and swallowing impairments on the primary caregivers of those with Alzheimer's Disease. Healthy adults and individuals with Alzheimer's disease will: - undergo tests of cough, voice, and swallow function - undergo tests of grip and tongue strength - complete questionnaires Caregivers of individuals with Alzheimer's disease will also complete questionnaires.
The goal of this study is to evaluate if using evidence-based, standard ingredient and target codes from the Rehabilitation Treatment Specification System - Voice Therapy (RTSS-Voice) in standard of care voice therapy documentation can improve outcomes for patients with muscle tension dysphonia (MTD). The main question it aims to answer is: Since the RTSS-Voice will help clinicians think about their treatment more specifically and in relation to nine evidence-based therapies, will its adoption be associated with improved outcomes? Clinicians across five voice centers will be asked to use the RTSS-Voice to document their voice therapy sessions for patients with MTD. Researchers will compare changes in outcomes between two groups of patients: those treated during the clinician's first year using the RTSS-Voice versus those treated during the clinician's second year using the RTSS-Voice.
This study aims to investigate whether there is a difference between groups receiving "group voice therapy" and "individual voice therapy" in pediatric populations diagnosed with dysphonia. In this context, the goal is to comprehensively examine the effectiveness of "group voice therapy" in pediatric populations compared to similar studies in the literature. In line with this objective, it is aimed to comprehensively test its effectiveness by including perceptual and acoustic evaluation findings, objective and subjective assessments, and incorporating comparison and control groups into the study, as compared to similar studies in the literature.
The general aim of the study is to provide evidence for usability and feasibility of applying vibro-tactile stimulation (VTS) at home as a non-invasive form of neuromodulation to improve speech in people with spasmodic dysphonia (SD). This work addresses a clinical need to develop alternative or auxiliary treatments for a rare voice disorder with very limited treatment options. Successful completion of the proposed work will be an important step in advancing laryngeal VTS as a therapeutic intervention for improving voice symptoms in SD.
The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic dysfunction in patients with functional dysphonia with gender- and age-matched vocally healthy controls, using a case-control study. The second objective is to compare the effects of a novel therapy based on autonomic nervous system regulation (i.e., ANS therapy: heart rate variability biofeedback), for functional dysphonia versus coventional voice therapy (CVT) alone or in combination with ANS regulation therapy (i.e., ANS therapy + CVT), using a longitudinal randomized controlled trial (RCT).
A previous study completed in 2022 (NCT05158179) was conducted using cohorts of healthy controls, and adults with general laryngopharyngeal disorders. This study will expand on the previous research to include a separate cohort of adults being seen in clinic for an existing laryngopharyngeal disorder resulting from previous radiation or other cancer treatments.
Early diagnosis and appropriate treatment of hoarseness is known to improve quality of life and treatment outcomes. Therefore, appropriate research on the incidence of hoarseness after surgery is necessary. In this study, investigator aim to investigate incidence of hoarseness after spine surgery and the correlation between the Voice Handicap Index (VHI)-10, used as a criterion, and acoustic parameters, while also validating the efficacy of our research methods.
Vocal hyperfunction (VH) is the most commonly treated class of voice disorders by speech-language pathologists and voice therapy is the primary curative treatment. Patients and clinicians report that generalizing improved voicing into daily life is the most significant barrier to successful therapy. We will test if extending biofeedback into the patient's daily life using ambulatory voice monitoring will significantly improve generalization during therapy and if individual patient factors, like how easily they can modify their voice and engagement during therapy, moderate the effects of the biofeedback.
Following a thyroidectomy, voice and swallowing alterations, which more frequently would appear to be caused by lesions of the laryngeal nerve, may occur. But, voice and swallowing changes can also occur in the absence of lesions of the inferior laryngeal nerve or the external branch of the superior laryngeal nerve, defining a condition called central compartment syndrome or functional post-thyroidectomy syndrome. It has been demonstrated that, in the presence of the aforementioned syndrome, the quality of the voice undergoes a deterioration immediately after thyroidectomy surgery with a lowering of pitch. The purpose of this study will be to verify the effects of early speech therapy, including pre-operative speech therapy counseling (during which the patient will be provided with indications to be implemented in the immediate post-operative period).
