1. A method of estimating adistribution of fibres recruited by astimulus, the method comprising:
applying a stimulus via a stimulus electrode;
obtaining from at least two sense electrodes spaced apart along a neural pathway respective measurements of a compound 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;
determining a conduction velocity of the compound action potential from the latency between the measurements, and determining from the conduction velocity a dominant recruited fibre diameter;
determining a rate of dispersion of the compound action potential between the sense electrodes, and determining from the rate of dispersion adistribution of diameters of the recruited fibre population.
