There were 46 patients with cervical myelopathy who were diagnosed by clinical signs were radiographic studies. All had extradural defects with distortion of the cervical cord and partial or complete obstruction on nyelogram.

SEP study, stimulating tibial nerve at the ankle revealed abnormality or 76.1% and median nerve 37% and combined median and tibial nerves 78.3%. There were 46 patients with radiculopathies confirmed by electromyography.

Electromyographic examination showed cervical radiculopathy in all of 46 patients.

Cervical myelopathy is pretty common with a high morbidity in general old people. The results indicate SEP stimulating tibial nerve is more sensitive index in the diagnosis of cervical cord pathology than median nerve stimulation.
