Importance of electromiographic examination in diagnostification and monitoring of chronic inflammatory demyelinating polyneuropathy

Polyneuropathies or peripheral neuropathies present a dysfunction or disease of larger number of peripheral nerves or their dysfunction. Considering their morbidity - mortality characteristics they present an important aspect in daily clinical practice. One particular polyneuropathy that deserves special review is chronic inflammatory demyelinating polyneuropathy, which, due to its clinical-laboratory presentation, does not include the group of "simple" neuropathies, thus requiring further examinations. Neurophysiological testing should be performed using the protocol for neuropathy examinations. Neurophysiological examination, during the electroneurographic examination, shows neurographic parameters referring to polyneuropatic demyelinating type of lesion, while the electromyographic finding records the presence of neuropathic lesions (denervation activity, great action potentials with a reduced sample).
