Caracterización electrofisiológica de un grupo de pacientes con polineurorradiculopatía desmielinizante inflamatoria crónica

a peripheral nerve conduction study was conducted among 12 patients clinically suspected of chronic inflammatory demyelinating polyradiculoneuropahty with a time of evolution from 21 days to 1 year. the median, deep peroneal and sural nerves were studied aimed at contributing to the electrophysiological characterization of the nerve conduction study in this pathology and at demonstrating the usefulness of new variables, such as the percentage of the falling of amplitude, area and dispersion in the electrophysiological diagnosis. it was proved that the most sensitive variables in this pathology are: latency at the proximal and distal beginning, proximal duration, duration of the proximal negative phase, nerve conduction velocity at the peak, percentage of the decrease of amplitude, area and dispersion in the motor study, latency at the beginning and at the peak, duration, and nerve conduction velocity at the beginning and at the peak in the sensitive study that showed the degree of alteration
