Abstract
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.
