Abstract
A method of parameterizing and evaluating somatosensory evoked potentials (SEPs) based on the SEP's Hilbert transform, a signal in the time domain, is developed. The latencies at which the Hilbert transform amplitude passes through zero are extracted. In order to test the Hilbert transform as a classification tool for SEPs, the MS method was developed. This method is based on the existence and latencies of five consecutive Hilbert transform zero crossings, which correspond to five SEP peaks of alternating polarity, and thus define an M waveshape in the SEP. Classification by this method agrees with independent clinical evaluation of SEPs for seven of ten control subjects and for eight of ten patients with cervical spondylosis myelopathy.
