Since central nervous system involvement is prominent in multiple sclerosis (MS), no abnormality is expected in peripheral nerve conduction studies. However, there are studies in the literature supporting the abnormalities in peripheral nerve conduction studies in patients with MS. Our aim in this study is to determine whether there is peripheral nerve involvement in patients with Relapsing-Remitting MS (RRMS) with peripheral nerve conduction studies. Conduction velocity, distal latency (DL) and action potential amplitude in median, peroneal, tibial and sural nerves were compared by electromyography (EMG) between 20 patients who were diagnosed with definite RRMS according to McDonalds criteria revised in 2001 and 15 control group. In the comparison of EMG studies performed between the patient and control groups, no statistically significant difference was found between conduction velocity, DL, and action potential amplitudes. Although no statistically significant difference was found between the patients with MS and the control group in our nerve conduction studies, peripheral nerve involvement was observed between 5% and 14% in the subgroups of patients with MS in various studies. There is a need for more comprehensive studies with a larger sample size on this subject.
