Relationship between Electrically Evoked Compound Action Potential Thresholds and Auditory, Language, and Speech Progress after Cochlear Implant Surgery
Introduction: Electrically evoked compound action potential (ECAP) is an objective auditory response that can be used in the programing of cochlear implants. The aims of this study were to monitor ECAP thresholds and auditory, language and speech progress for 6 months after cochlear implant surgery and to evaluate any relationship between them. Materials and Methods: Ten children with a m...
متن کاملFacilitation and refractoriness of the electrically evoked compound action potential
In this study we aim to resolve the contributions of facilitation and refractoriness at very short pulse intervals. Measurements of the refractory properties of the electrically evoked compound action potential (ECAP) of the auditory nerve in cochlear implant (CI) users at inter pulse intervals below 300 μs are influenced by facilitation and recovery effects. ECAPs were recorded using masker pu...
متن کاملThe Electrically Evoked Compound Action Potential: From Laboratory to Clinic
The electrically evoked compound action potential (eCAP) represents the synchronous firing of a population of electrically stimulated auditory nerve fibers. It can be directly recorded on a surgically exposed nerve trunk in animals or from an intra-cochlear electrode of a cochlear implant. In the past two decades, the eCAP has been widely recorded in both animals and clinical patient population...

چکیده مهارت شنیداری برای مدتهای طولانی در آموزش ، تحقیق و ارزیابی مورد غفلت قرار گرفته است. اگرچه در سالهای اخیر به خاطر اهمیت قابل ملاحظه این توانائیها در آموزش و آزمون زبان ، توجه بیشتری به توانائیهای شنیداری شده است. هم چنانکه درک شنیداری در آموزش و ارزیابی زبان دوم اهمیت فزاینده ای می یابد محققین سعی نموده اند تا ماهیت مهارتهای مستتر در مهارت شنیداری را مورد بررسی و مطالعه قرار دهند. هدف ...
15 صفحه اولInfluence of evoked compound action potential on speech perception in cochlear implant users.
UNLABELLED Electrically Evoked Compound Action Potential is a measure of synchronous cochlear nerve fibers activity elicited by electrical stimulation of the cochlear implant. The electrophysiological nerve responses may contribute to explain the variability in individual performance of cochlear implant recipients. AIM To compare speech perception tests performances of cochlear implant users ...
