An attempt has been made to characterize Compound Nerve Action Potentials from normals and Hanseniasis patients using wavelet transforms. The work reported here involves classification of peripheral potentials recorded at the elbow of normals and Hanseniasis patients following electrical stimulation of the median nerves. Employing the system developed by the first author, nerve conduction data has been obtained from 8 normals and 8 Hanseniasis patients. The neuro-pfaysiologkal data so collected was prcprocessed to normalize the energy of the various responses and was analyzed using the Discrete Wavelet Transform. A new parameter, defined in the transform domain and termed as Inlra-scale Inter-epoch Energy Ratio, could clearly demarcate the normals and the Hanseniasis patients at a particular scale.
