NCT ID: NCT06305039 Enrolling by invitation - Hearing Loss Clinical Trials

Optimizing Bilateral and Single-sided-deafness Cochlear Implants for Functioning in Complex Auditory Environments

Start date: December 19, 2023
Phase: N/A
Study type: Interventional

Cochlear implants (CIs) are devices that partially restore hearing for people with severe to profound hearing loss. This research focuses on CI users who use bilaterally implanted devices (two CIs, one on each side) and also "single-sided deafness" (SSD) CI users who use one CI together with good acoustic hearing in their opposite ear. The goal is to measure and understand the impact of large input asymmetries across the two ears. These asymmetries are common in BI-CI listeners and always present in SSD-CI users. Although most CI listeners benefit from a second source of auditory input, this project measures how these asymmetries limit speech understanding and spatial hearing. The long-term goal is countering or compensating for input asymmetries. Electrophysiological measures are used to describe the health of the auditory system. Behavioral measures are used to assess if training improves performance. CT imaging is utilized to describe the placement of the CIs.

Retrospective Analysis of Speech Performance Using the HiRes Ultra and HiRes Ultra 3D Cochlear Implant

Start date: January 22, 2024
Phase:
Study type: Observational

This is a retrospective study designed to collect speech perception results for HiRes Ultra CI and HiRes Ultra 3D CI users as measured in the clinical routine and to confirm the performance of these devices.

NCT ID: NCT06301568 Recruiting - Clinical trials for Cochlear Hearing Loss

Retrospective Analysis of Long-term Speech Performance in Cochlear Implant Recipients Using Electro-acoustic Stimulation

Start date: January 22, 2024
Phase:
Study type: Observational

This is a retrospective study designed to collect long-term speech perception results for cochlear implants recipients using electro-acoustic-stimulation as measured in the clinical routine and to confirm the performance of sound processors associated with acoustic earhooks.

NCT ID: NCT06235073 Completed - Clinical trials for Cochlear Hearing Loss

Robotic and Manual Cochlear Implantation: An Intra-individual Study of Speech Recognition and Electrode Holder Position (ICRobMan)

ICRobMan
Start date: July 1, 2023
Phase:
Study type: Observational

Cochlear implantation (CI) allows rehabilitation for patients with severe to profound hearing impairment. Although the use of a robotic assistant provides technical assistance to the surgeon, the assessment of the impact of its use on auditory outcomes remains uncertain, due to inter-individual variability of preoperative audiometric thresholds and the various possible intrascalar positions of the electrode array. WThe investigators aim to compare the hearing results of patients who underwent bilateral cochlear implantation, one side was performed with manual insertion and the other side with robot-assisted insertion. The electrode array intrascalar positioning and the surgery duration were also studied. This retrospective intra-individual study involved 10 patients who underwent bilateral cochlear implantation. The unique composition of this cohort enabled the investigators to utilize each patient as their own control.

NCT ID: NCT06128161 Completed - Clinical trials for Cochlear Hearing Loss

Comparison of Unilateral CI vs. Bimodal Stimulation in Prosodic Perception

Start date: August 30, 2022
Phase:
Study type: Observational

An observational study to determine and assess perception of prosodic information in adults who use bimodal stimulation (cochlear implant plus hearing aid) when using both devices vs. cochlear implant alone.

NCT ID: NCT06114680 Recruiting - Clinical trials for Hearing Loss, Sensorineural

Evaluation of the CochSyn Test Prototype to Measure Cochlear Synaptopathy

EarDiTech
Start date: November 13, 2023
Phase: N/A
Study type: Interventional

This study investigates a newly developed test, The CochSyn test that can quantify cochlear synaptopathy (CS) (a new type of sensorineural hearing loss (SNHL)) earlier than the current golden standard pure-tone audiogram.This newly developed test is based on auditory evoked brain potentials. A hardware prototype (the Cochsyn test prototype) was developed to use the Cochsyn test in clinical practice. Additionally a CS-based sound-processing algorithm (CoNNear) that is designed to improve speech intelligibility in subjects that are identified to have CS, will be investigated in this study.

NCT ID: NCT05709431 Recruiting - Quality of Life Clinical Trials

A Study Evaluating the French Version of the CIQoL-35 Quality of Life Questionnaire in Adult Cochlear Implant Use.

CIQoL
Start date: January 12, 2022
Phase:
Study type: Observational

The Cochlear Implant - Quality of Life (CIQoL) PROM is a quality-of-life assessment questionnaire for adults with cochlear implants. The CIQoL responds to an important need for a questionnaire that captures the benefits of cochlear implantation as perceived by patients and that can be used in clinical practice.

NCT ID: NCT05586555 Recruiting - Clinical trials for Hearing Loss, Sensorineural

A Monocentric Study Evaluating Pupillometry as an Objective Measurement for CI Fittings

PupillOM
Start date: May 2, 2023
Phase: N/A
Study type: Interventional

This trial is a monocentric, prospective and controlled study of the pupil response to detect hearing threshold and comfortable loudness of normal-hearing (NH) and CI-subjects.

NCT ID: NCT05554692 Enrolling by invitation - Aging Clinical Trials

Peripheral and Central Influences on Auditory Temporal Processing & Speech Perception in Older Cochlear Implantees

Start date: August 3, 2022
Phase: N/A
Study type: Interventional

Older adults who use cochlear implants to address hearing loss show wide variation in benefit. This research investigates the role of normal aging, the health of peripheral and central auditory pathways, and positioning of the cochlear implant electrode array in contributing to this variability. A range of input types from simple auditory signals to spoken sentences is used to examine these questions.

NCT ID: NCT05486637 Recruiting - Clinical trials for Cochlear Hearing Loss

Vocal Emotion Communication With Cochlear Implants

Start date: July 1, 2022
Phase: Early Phase 1
Study type: Interventional

Patients with hearing loss who use cochlear implants (CIs) show significant deficits and strong unexplained intersubject variability in their perception and production of spoken emotions in speech. This project will investigate the hypothesis that "cue-weighting", or how patients utilize the different acoustic cues to emotion, accounts for significant variance in emotional communication with CIs. The results will focus on children with CIs, but parallel measures in postlingually deaf adults with CIs will be made, ensuring that results of these studies benefit social communication by CI patients across the lifespan by informing the development of technological innovations and improved clinical protocols.
