Filter by:Hearing loss is one of the most prevalent impairments in the world. The World Health Organization estimates that as of 2020, around 466 million people worldwide are affected by disabling hearing loss, of which 34 million are children. Without appropriate diagnosis and treatment, hearing impairment can cause difficulties with communication, learning, social-emotional functioning, employment and quality of life. Early intervention is especially important for children, for whom unaddressed hearing loss has been proven to affect speech and language development, educational attainments, and social skills. Through early detection and interventions many of these impacts can be mitigated, highlighting the importance of accurate hearing diagnostics. Evaluation of speech intelligibility is a fundamental component of hearing assessment and rehabilitation. The current gold standard in measuring speech intelligibility relies heavily on behavioural tests. While these tests are reliable and fast in healthy adults, it is challenging to assess speech intelligibility for patients who cannot communicate clearly, such as young children. For example, behavioral tests require active participation from the patient, such as raising their hand when a sound is heard, or repeating words and sentences. Objective measures, for instance using electro-encephalography (EEG), could overcome the current challenges in hearing assessment and do not require active participation from the patient. For example, in Flanders, all newborns are screened with an objective test where a few sensors on the head detect brainwaves in response to sounds. However, objective tests only use simple sound stimuli, such as tones or clicks, which cannot be used to measure important high-level hearing outcomes, such as speech understanding. In other words, current objective tests are used to check if a person can hear a word, but they can't indicate if the person can understand the word. An obvious missing link in audiological practice is a diagnostic test that can measure high-level hearing outcomes such as speech understanding in an objective way. For this reason, CORGEE was developed. CORGEE uses a novel method of "neural speech tracking" to objectively measure speech intelligibility using EEG. In the current study, the efficacy and the clinical validity of the CORGEE software will be evaluated in young children with a hearing impairment.
The hypothesis of this research is that the AS Target setting provides the best estimate of the settings required to optimize listening in noise. As such, it is expected that speech in noise performance will be best in the AS Target condition, followed by the AS Clinic condition, and the Omni condition will be the least favourable for speech in noise performance
The Montreal Cognitive Assessment (MoCA) is a screening test for detecting cognitive impairment that assesses several cognitive domains (attention and concentration, arithmetic and orientation, memory, etc.). The instructions as well as some test items of the MoCA are presented auditory (spoken). Consequently, performance on the MoCA may be co-dependent on hearing. Therefore, to rule out the possible negative influence of hearing loss on performance on the MoCA, a MoCA for individuals with hearing loss was recently developed. More specifically, the original MoCA was modified by providing the instructions audiovisually (spoken with visual support) as well as by replacing hearing-dependent items. Since replacing items may affect sensitivity and specificity, the MoCA for persons with hearing loss should be revalidated.
The overarching hypothesis to be evaluated using this protocol is that age-related hearing loss (ARHL) leads to shifts in the functional spatial boundaries between segregated and integrated auditory streams, and that hearing aid intervention that relies on directional processing schemes is most effective for those that have the poorest spatial sensitivity. One key component of the research design is to measure both behavioral and neurophysiological indices of an individual's spatial segregation boundary. The second key component is to measure the cost or benefit associated with hearing aid intervention in older hearing-impaired listeners. The final component is to relate cost and benefit of hearing aid intervention to spatial sensitivity measures that might predict the efficacy of clinical intervention.
This study intends to assess safety, tolerability, and efficacy of SENS-501 in children between the ages of 6-31 months with pre-lingual hearing loss due to a mutation in the Otoferlin gene.
The goal of this observational study is to describe the multi-omics characteristics and to learn about the prognostic factors in patients with idiopathic sudden sensorineural hearing loss (SSNHL). The main problems it aims to deal with are: - if there is a difference in data of exome and targeted sequencing among patients with SSNHL affecting bilateral and unilateral sides, and healthy controls - if there is a difference in the parameter of MRI among patients with SSNHL affecting bilateral and unilateral sides, and healthy controls - to find out which factor from multi-omics data relates to outcomes of SSNHL - to develop the best prognostics model based on the multi-omics data. Participants will be received audiological tests, blood specimen collection and radiological examination. Researchers will explore the relationship between the multi-omics data and the prognosis and develop the predictive model.
Congenital hearing loss, as well as hearing loss present at birth, is one of the most common chronic conditions in children, with a prevalence of permanent bilateral hearing loss of 2.83 per 1000 children of primary school age, which is mainly caused by genetic factors. The goal of this observational study is to learn about novel causative genes in infants with hearing loss in the Chinese population. The main problem it aims to deal with are: - to present the genetic characteristics of the infant with hearing loss in the Chinese population - to build up a prognostic model base on diverse data. Participants will be asked to receive audiological tests and collection of the peripheral blood sample.
The goal of this clinical trial is to investigate the factors and mechanisms underlying tinnitus generation and chronification in patients with sudden sensorineural hearing loss (SSNHL) . The main questions it aims to answer are: - What are the peripheral and central influencing factors that contribute to tinnitus in patients with SSNHL? - Can serum metabolic biomarkers be identified to predict and monitor tinnitus prognosis in these patients? Participants in this study will include patients with SSNHL and tinnitus, patients with SSNHL without tinnitus, and healthy subjects. They will be asked to undergo a series of assessments, including audiological tests, vestibular function examinations, and functional magnetic resonance imaging (fMRI). Additionally, blood samples will be collected for metabolomics analysis. Investigators will compare the brain functional states and serum metabolite profiles of patients with SSNHL and tinnitus to those without tinnitus. Morever, tinnitus symptom characteristics, audiological outcomes, and brain functional states will be assessed during time.
Children's motor skills and physical performance increase with age due to the development of neuromuscular and cardiorespiratory systems. Sensory impairment seen in children with hearing loss can cause balance and coordination disorders, as well as decreased muscle strength and respiratory functions. Anatomically, core stabilization is provided by the diaphragm, abdominal, hip, pelvic floor, and gluteal muscles. Training for these muscles is intended to improve strength, endurance, and neuromuscular control. This training can help to improve the control of intra-abdominal pressure, intersegmental control of the spine, and muscular control of trunk movement. It also helps in strengthening the respiratory muscles, especially the main inspiratory muscle, the diaphragm. In this study, the effects of core stabilization training on children with hearing impairments' thoracic mobility, functional ability, and trunk muscle endurance will be examined.
The purpose of this study is to characterize and assess the evolution of hearing impairment of patients with adulthood-onset bilateral sensorineural hearing loss carrying mutations on GJB2 gene.
