Filter by:It has been shown that in deaf people, cortical reorganisation occurs and can accelerate age-related cognitive decline. Therefore, even though a number of Cochlear Implantation Reference Centres are setting up tests to detect cognitive disorders, these remain global and not very specific to deafness. Similarly, auditory rehabilitation could make cognitive decline reversible and bring about major changes in the cognitive functioning of patients which will be decisive for the effectiveness of speech therapy and the effectiveness of implantation. Indeed, it has been shown that, in the deaf postlingual patient, less neuronal activity in the auditory cortex and a reallocation of the cortical regions dedicated to auditory processing to visual tasks took place. This could subsequently influence the outcome of the cochlear implant. The aim of this study is therefore to evaluate the effectiveness of targeted speech therapy aimed at cognitive reorganisation on post-implant gain.
Individuals with cochlear implants will complete tasks which measure auditory resolution, working memory, stream segregation, and speech recognition in the presence of competing speech using their everyday clinical device settings. The relationship between these tasks will be examined to identify the factors which predict successful speech recognition in the presence of competing speech.
The purpose of this study is to see if remote programming visits for cochlear implants are possible.
The goal of this study is to improve music and speech perception for cochlear implant users. Presently, most cochlear implants discard the temporal fine structure of sound, which is information that is widely believed to contribute to both music and speech perception. The proposed work examines perceptual and physiological changes that occur once this information is provided to cochlear implant users in a clear and consistent manner.
This clinical investigation aims to collect data on the use of the Mi2000 system, a totally implantable cochlear implant system, for the first time in human subjects.
The current standard of care for cochlear implants (CI) does not address the significant pitch-place mismatch that is inherent in cochlear implantation (see detailed description below). The present study uses postoperative Flat Panel (higher resolution than standard) CT imaging to measure where CI electrodes sit within an individual's cochlea; doing so allows for more accurate frequency mapping (and thus pitch perception). The hypothesis of this study is that long-term (1 year) use of CT image-based frequency maps, beginning on the first day of CI activation, will improve user performance in the areas of speech and music perception, as compared to the use of default programming settings.
Multi-channel cochlear implants have been highly successful in restoring speech understanding to individuals with severe-to-profound hearing loss. Optimal programs facilitate access to sound but do not necessarily result in optimal performance. Practiced listening with auditory inputs is required to retrain the brain to hear using a cochlear implant. In some cases exposure to sound in everyday listening is sufficient; however, in others there is a need for the provision of auditory training (AT) by a trained professional. In these cases it is important to have regular visits with a specialist to: 1) facilitate auditory training exercises; 2) work with the family/friends to encourage optimal communication strategies in the home; 3) evaluate and assess achievement of listening goals. This study seeks to evaluate the feasibility of providing auditory training services remotely for patient populations located outside of Toronto. This study also seeks to evaluate interindividual perspectives regarding access and benefits of these services across remote and in person sessions.
This project aims to characterize the emergence of music appreciation in people who have suffered hearing loss and have been provided with partial restoration of hearing through cochlear implantation. Music appreciation is complex and transverses multiple domains including hearing acuity, speech and language acquisition, and quality of life. By studying these relationships in people who have been given partial hearing restoration, the investigators will clarify the role of music for promoting recovery from debilitating loss.
In the field of cochlear implant research, there are only few data on long-term observational studies available to gain knowledge on clinical effectiveness. Longitudinal comparisons of data collected in different clinics is challenging due to the heterogeneity in measures and procedure. This Registry represents a non-interventional systematic collection of clinical data in which prospective data from children and adults are collected as anonymized data sets, derived from original clinical records on appropriately informed subjects. Each subject will be treated as per clinical routine. The Registry will be implemented through a secure, cloud-based, platform that enables collection of anonymized data at consistent time intervals, thus enabling the comparison of repeated measures over time.
The goal of this study is to take into account channel interaction in the cochlear implant (CI) fitting process. Designing a fast and accurate method of measurement would help to customize the fitting procedures to patients' specificities in order to maximize speech understanding in every day conditions especially in noise.
