Abstract

Clinical usefulness of somatosensory evoked potentials (SSEP) as a prognostic tool was evaluated with three dogs showing clinical signs associated with intervertebral disc diseases. Prior to measure SSEP, history taking, physical examination, radiological study and neurological examination were performed. In case 1, poor prognosis was predicted because deep pain was not observed and loss of sensory function was observed in SSEP. And the clinical signs persisted with the conservative treatment. However, in cases 2 and 3, good prognoses were predicted by normal conduction velocity in SSEP that meant the presence of sensory function. The clinical signs of cases 2 and 3 disappeared at days 18 and 13 after treatment, respectively. These results suggest SSEP be used clinically as a prognostic tool in dogs with intervertebral disc diseases.
