1. A system for delivering neurostimulation energy to a patient having a spinal cord, the system comprising:
a stimulation control circuit configured to control the delivery of the neurostimulation energy according to each test pattern of a plurality of neurostimulation test patterns, the stimulation control circuit including:
a sensing input configured to receive an electrospinogram (ESG) signal including responses from the spinal cord evoked by the delivered neurostimulation energy, the evoked responses including evoked compound action potentials (ECAPs);
a measurement circuit configured to determine a response parameter for each test pattern of the plurality of neurostimulation test patterns using the received ESG signal, the response parameter associated with a morphological feature of the ECAPs in the ESG signal; and
a selection circuit configured to determine a neurostimulation therapy pattern by selecting a test pattern from the plurality of neurostimulation test patterns using the response parameter.
