Comparing Site-selection Strategies

NCT03870217 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2024-06-28

No results posted yet for this study

Summary

Several studies in the past have tried to deactivate electrodes that are less optimal to improve speech recognition outcomes. The study aims to compare the measures based on which the deactivation was performed. The investigators aim to first examine if the measures are strongly correlated each other, and then compare the deactivation effects across measures. These measures are mainly behavioral including electrode discrimination, amplitude modulation detection thresholds, low-rate and focused detection thresholds and electrode-modiolus distance. The endpoint of the study is speech recognition performance post deactivation.
