2 Clinical Trials for Various Conditions
The goal of this study is to study the adaptation process in newly implanted Single-Sided Deaf Cochlear Implant (SSD-CI) users. Subjects will use four frequency maps for the first month after CI activation. One of these maps will be standard of care and the other three will have higher low frequency edges than the standard of care default maps. These maps will alternate daily during the first month (with exceptions made for situations when the subject is allowed to use a preferred map rather than the map predetermined for use that day), and after that point each subject will make a selection at the beginning of the week to compare all four maps and decide which one to use at the beginning of the following week. The goal of this study is to investigate how reducing place-pitch mismatch in SSD CI users affects 1) sound quality, 2) device use, and 3) speech perception.
Preliminary data will be collected about which individuals with spatial neglect from right hemisphere stroke (aiming vs perceptual neglect) improve with Prism Adaptation Training and if there is a particular pattern of damage in the brain that predicts both the type of neglect experienced and whether neglect is improved following Prism Adaptation Training
