Percentage (%) of device programming parameter settings with non-default values . Four parameters, including pulse width, stimulation rate, number of active channels, and number of maxima are shown for each of the six etiology groups (EGp). The 6 groups are: 1) auditory nerve deficiency; 2) cochlear lesions, 3) enlarged vestibular aqueduct; 4) auditory neuropathy spectrum disorder; 5) additional disabilities; and 6) Other (unknown etiology, genetic factors, and cytomegalovirus infection) Data are shown for device settings at 6-months post-activation (white bars), and chronological ages of 3 (light grey bars) and 5 years (dark grey bars) for 88 children (n=98 ears).
