The value of pelvic thrusting in the diagnosis of seizures and pseudoseizures

Abstract

We evaluated pelvic thrusting as a potential diagnostic sign and localizing indicator of ictal onset. By reviewing the video-EEG results of patients with temporal lobe epilepsy, frontal lobe epilepsy, generalized epilepsy, and pseudoseizures. Pelvic thrusting occurred in 4% of right and 2% of left temporal lobe epilepsy patients, in 24% of frontal lobe epilepsy patients, and in 17% of patients with pseudoseizures. Pelvic thrusting is relatively common in frontal lobe epilepsy and in pseudoseizures, but also occurs in temporal lobe epilepsy.
