Clinical application of neuromuscular electrophysiology in the dog: a review

A review of the literature concerning the application of electromyography and electroneurography in canine neurology is presented. Measurements of amplitude and duration of motor unit potentials in normal dogs varied largely in the various reports. It was therefore concluded that these measurements are of limited clinical value. The results of motor and sensory nerve conduction studies in normal dogs are summarised. The differences between the methods used are discussed. It is concluded that variations in reported normal values are due mainly to differences in method. The application of electromyography and electroneurography in neuromuscular disorders in the dog is systematically presented, based upon the reported diagnoses. The considerable number of first descriptions of newly-recognised and described neuromuscular diseases appears to be related to the introduction of neuromuscular electrophysiology into veterinary medicine.
