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

We evaluated pelvic thrusting as a potential diagnostic sign and localizing indicator of ictal onset. By reviewing the video-EEG results of patients w ith temporal lobe epilepsy, frontal lobe epilepsy, generalized epilepsy, an d pseudoseizures. Pelvic thrusting occurred in 4% of right and 2% of left t emporal lobe epilepsy patients, in 24% of frontal lobe epilepsy patients, a nd in 17% of patients with pseudoseizures. Pelvic thrusting is relatively c ommon in frontal lobe epilepsy and in pseudoseizures, but also occurs in te mporal lobe epilepsy.
