Claim 4:
5. A device for estimating adistribution of fibres recruited by astimulus, the device comprising
at least one stimulus electrode and at least two sense electrodes, configuredto be spaced apart along a neural pathway;
measurement circuitry for obtaining a neural measurement from each sense electrode; and
a processor configured to apply a stimulus via the stimulus electrode, obtain from the at least two sense electrodes respective measurements of acompound action potential propagating along the neural pathway, wherein the compound action potential is an evoked compound action potential (ECAP) of the fibres recruited by the stimulus, determine a conduction velocity of the compound action potential from a latency between the measurements, determine from the conduction velocity a dominant recruited fibre diameter, determine a rate of dispersion of the compound action potential between the sense electrodes, and determine from the rate of dispersion a distribution of diameters of the recruited fibre population.
