Juvenile Myoclonic Epilepsy and Progressive Myoclonic Epilepsy

Post hypoxic myoclonus, Post ischemic stroke myoclonus, Hepatic, Chronic kidney disease, and Drug induced myoclonus

Stimulation of the right and left median nerves for each subject were carried out with electrical square wave pulses of 0.2 ms duration applied at a rate of 5 HZ. with cathode proximally. The intensity of the stimulus was adjusted to produce minimal twitches of the thumb (1-2 cm thumb movement). Five hundred (500) stimuli were delivered. The recording electrode picked up the responses. They were then summated and averaged.

The final evoked potential was then displayed on the screen. When two reproducible SEPs responses were obtained the data was accepted for analysis. The graph was printed out on paper, for the purpose of simplification only one response was printed out.
