Filter by:The objective of this study is to compare remote and in-person audiological cochlear implant candidacy evaluations (including audiological (hearing) testing and counseling sessions) in a rural Appalachian region.
The project will be done at the ear, nose and throat outpatient department at Lovisenberg Diakonale Hospital (LDS) in 2015-2016. About 12% of patients with appointments at the surgical outpatient clinic at LDS do not attend their appointment even after receiving both letters and shot message service (SMS) reminders. Persuasion theory suggests that the SMS reminders may be more effective if the text appeals more to the patient's feelings. The project is designed as a randomized controlled trial in which the control group receives the standard text that has neutral content and the intervention group receives a more emotion-based SMS reminder. The aim is to determine whether the more emotional text reduces the proportion of patients who do not show up for their scheduled appointment at the surgical outpatient clinic.
The purpose of this feasibility study is to evaluate whether low-frequency acoustic hearing sensitivity can be preserved in newly implanted adults with partial deafness (considerable low frequency acoustic hearing profiles with severe-to-profound high frequency sensorineural hearing loss) using the HiResolution™ 90K™ Advantage cochlear implant with the HiFocus™ Mid-Scala electrode to support the development of electro-acoustic stimulation technology (EAS).
The present study aims to examine the efficacy of transcranial direct current stimulation on the severity of auditory hallucinations.
The purpose of this study is to determine the feasibility of preserving low-frequency acoustic hearing in adults with a moderate degree of hearing loss in the low frequencies and severe-to-profound hearing loss in the mid-to-high frequencies who are implanted with the HiRes™ 90K Advantage implant with HiFocus™ Mid-Scala electrode.
The overall aim of the study is to investigate the Ponto wide implant considering; initial implant stability, stability over time, skin reaction and long term success when loaded at 3 weeks post surgery. Patients' quality of life improvements following implantation will also be surveyed. More specifically the primary objective of this clinical study is to test the hypothesis - The new Ponto wide diameter implant offers increased implant stability measured as ISQ (implant stability quotient) compared to the previous generation Ponto implant. And the secondary objective is to - Investigate when in time implant stability is the lowest as the initial mechanical stability is gradually replaced by biological stability
The purpose of this study is to determine whether ancrod is effective and safe in the treatment of sudden sensorineural hearing loss (SSHL).
Background: - People with epilepsy often have auditory processing disorders that affect their ability to hear clearly and may cause problems with understanding speech and other kinds of verbal communication. Researchers are interested in developing better ways of studying what parts of the brain are affected by hearing disorders and epilepsy, and they need better clinical tests to measure how individuals process sound. These tests will allow researchers to examine and evaluate the effects of epilepsy and related disorders on speech and communication. - A procedure called a magnetoencephalography (MEG) can be used to measure the electrical currents involved in brain activity. Researchers are interested in learning whether MEG can be used to detect differences in the processing of simple sounds in patients with epilepsy, both with and without hearing impairments. Objectives: - To measure brain activity in hearing impaired persons with epilepsy and compare the results with those from people with normal hearing and epilepsy as well as people with normal hearing and no epilepsy. This research is performed in collaboration with Johns Hopkins Hospital and epilepsy patients must be candidates for surgery at Johns Hopkins. Eligibility: - Individuals between 18 to 55 years of age who (1) have epilepsy and have hearing impairments, (2) have epilepsy but do not have hearing impairments, or (3) are healthy volunteers who have neither epilepsy nor hearing impairments. - Participants with epilepsy must have developed seizures after 10 years of age, and must be candidates for grid implantation surgery at Johns Hopkins Hospital.. Design: - This study will require one visit of approximately 4 to 6 hours. - Participants will be screened with a full physical examination and medical history, along with a basic hearing test. - Participants will have a magnetic resonance imaging (MRI) scan of the brain, followed by a MEG scan to record magnetic field changes produced by brain activity. - During MEG recording, participants will be asked to listen to various sounds and make simple responses (pressing a button, moving your hand or speaking) in response to sounds heard through earphones. The MEG procedure should take between 1 and 2 hours. - Treatment at NIH is not provided as part of this protocol.
The purpose of this study is to determine whether chronic electrical stimulation of the primary auditory cortex is effective in the treatment of chronic, severe and intractable tinnitus
This study will use magnetic resonance imaging (MRI) to compare brain function in three groups of people: hearing-impaired people with tinnitus; hearing-impaired people without tinnitus; and people with normal hearing and without tinnitus. Also known as "ringing in the ears," tinnitus is the false sensation of sounds. Adults between 30 and 65 years of age who meet the following criteria may be eligible for this study: - Mild to moderate hearing loss who have experienced tinnitus daily for at least 1 year - Mild to moderate hearing loss who have never or rarely experienced tinnitus - Normal hearing who have never or rarely experienced tinnitus Candidates are screened with a medical history and questionnaires. Participants have a detailed hearing test to measure hearing and the nature of tinnitus. In a second visit, subjects have a brief physical examination, followed by MRI scanning. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the subject lies on a table that can slide in and out of the scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The subject may be asked to lie still for up to 8 minutes at a time. During the MRI, the subject performs computer-based tasks that involve listening to sounds. Another hearing test is done after the MRI.
