Claim 22:
23. An implantable device for applying neural stimulus to neural tissue, the device comprising:
a plurality of electrodes including one or more stimulus electrodes and one or more sense electrodes;
a stimulus source for delivering stimulus pulses via the one or more stimulus electrodes to neural tissue;
measurement circuitry for measuring a neural signal sensed at the one or more sense electrodes: and
a control unit configured to:
control the stimulus source to deliver a plurality of therapeutic pulses to neural tissue via the one or more stimulus electrodes, the therapeutic pulses having a first pulse width, wherein the therapeutic pulses evoke neural responses;
control the stimulus source to deliver a plurality of probe pulses to the neural tissue having a second pulse width interleaved with at least some therapeutic pulses of the plurality of therapeutic pulses, wherein the second pulse width is less than the first pulse width;
control the measurement circuitry to measure, after a therapeutic pulse of the plurality of therapeutic pulses and prior to a subsequent probe pulse of the plurality of probe pulses, the neural response evoked by the therapeutic pulse;
determine a neural recruitment caused by the therapeutic pulse based on the neural response; and
determining a parameter for the subsequent therapeutic pulse based on the neural recruitment.
