1. A method of estimating a position of an electrode array relative to a nerve, the electrode array being implanted adjacent to the nerve, wherein the electrodes of the electrode array are configured to apply stimulation or sense evoked compound action potentials (ECAPs), the method comprising:
applying stimulation at at least one electrode;
measuring at least one of an amplitude and latency of the ECAPs;
increasing a stimulation intensity, and repeating the applying and the measuring, until an onset of a late response is observed;
measuring at least one of an amplitude and latency of the late response; and
estimating a position of the electrode array relative to the nerve based on the amplitude and latency of at least one of the ECAPs and the late response.
