The electrodiagnostic examination provides the basis for a diagnostic workup in diseases involving nerve roots, peripheral nerves, neuromuscular junctions and muscles in humans and animals. It is a functional test that enables identification, localization and characterization of the disease within the peripheral nervous system. The study was carried out retrospectively on a group of 61 dogs of different breeds referred for an electrodiagnostic examination because of local or generalized peripheral nervous system impairment. The electrodiagnostic examination consisted of electromyography, electroneurography, F-wave and repetitive nerve stimulation testing. The results of electrodiagnostic studies and their impact on the diagnosis of neuromuscular diseases of different etiology is presented in the study. The lesion was localized to peripheral nerves in 38%, nerve roots in 34%, skeletal muscles in 18% and the neuromuscular junction in 10% of cases.  Electrodiagnostics enabled an objective assessment of the extent, distribution and nature of the disease in the study group. However, only when it is used in conjunction with a complete physical and neurological examination and appropriate laboratory or imaging studies, it may be helpful in determining the etiological diagnosis in patients with peripheral nervous system disease.
