Abstract

In the last years the presence of peripheral nervous system (PNS) lesions has been noted in patients with multiple sclerosis (MS). The frequency and degree of PNS damage reported by many authors differ among publications, so does the type of PNS lesions. The aim of our study was to perform an electrophysiological evaluation of the peripheral nervous system in patients with a definite diagnosis of multiple sclerosis and without any clinical signs of peripheral neuropathy. 110 patients were included in the study, comprising 70 people with a definite diagnosis of multiple sclerosis and 40 people without any symptoms of organic nervous system lesion serving as a control group. During neurologic examination of MS patients the degree of disability measured by EDSS scale, the duration of the disease as well as number of relapses were assessed. A "disease progression factor" was calculated by dividing a number of relapses by disease duration in years. Patients with common etiologies for peripheral neuropathy such as diabetes, renal insufficiency, thyroid gland dysfunction, proliferative disorders etc. were excluded from the study. Orthodromic motor conduction and late responses (F wave) in median, ulnar, peroneal and tibial nerves as w...Continue Reading
