Design outcomes
Primary
| Measure | Time frame |
|---|---|
| IPGEslope as a measure of the change in the slope of the ECAP growth function in response to an increase in the interphase gap, serving as an indicator of cochlear health. Compared between the two groups with different durations of hearing loss, as well as for cathodic-leading stimulation and anodic-leading stimulation. | — |
Secondary
| Measure | Time frame |
|---|---|
| Percentage of speech recognition (% SR) in the monaural OLSA with noise using the S0N0 setup, and percentage of correctly repeated words in the Freiburg Monosyllable Test, compared to the IPGEslope. Pitch ranking at an apical and a basal electrode using the standard clinical phase duration and a very long phase duration (400 µs). | — |
