A system includes a cochlear implant (CI) device and a screening device. The CI device includes an electrode array comprising a plurality of stimulation electrodes to be implanted in a patient's cochlea for electrical stimulation of the cochlea, a stimulation signal unit for generating stimulation signals to be supplied to the stimulation electrodes, and a unit for capturing ECAP signals induced at the electrodes in response to stimulation of the cochlea by applying stimulation signals to the electrodes. The screening device is adapted to cooperate with the stimulation signal unit in a manner so as to provide the electrodes with stimulation signals suitable for conducting growth function measurements, recovery measurements and spread-of-excitation measurements.
