Hi,
SSEP is Somatosensory Evoked Potentials, its an electrical study, they send electrical currents thru the arms/legs and then read the signal in the brain. My nuerologist talked about this but he did a EMG where they send electrial signal down the arm. The EMG was not too painful, just a little uncomfortable.
Good Luck
