Well, the authors apparently want to define "rub epilepsy" as "a type of reflex
epilepsy induced by prolonged or repetitive cutaneous stimulation in a circumscribed
area of the body"....
"Rub epilepsy is proposed as a separate clinical entity, clearly demarcated
from other somatosensory evoked reflex epilepsies such as startle and tooth
brushing epilepsy."

This is bescause "until recently, somatosensory evoked epilepsy without
an element of surprise has been confused with other types of
somatosensory evoked epilepsy such as startle epilepsy."
They seem to think that this is clinically important. 

They further propose that the "seizure symptomatology of rub epilepsy indicates
a propagation of epileptic discharges from the postcentral gyrus to the
supplementary motor  area".
