文摘
- •
ECAP amplitude growth function could be measured in nearly 90% of the electrodes.
- •
The ECAP amplitude and slope varied significantly across electrode site, within an ear.
- •
Increasing the interphase gap resulted in increased amplitude and slope.
- •
The ECAP slope was negatively significantly related to duration of hearing loss.
- •
Some, but not all, ECAP measures correlated with across-site impedance values.
