Semiological value of rhythmic ictal non-clonic hand (RINCH) motions in epileptic seizures

RINCH motions represent an uncommon but distinctive manifestation of epileptic seizures, often accompanied by impaired awareness, automatisms and aphasia. These movements typically occur in the hand contralateral to the seizure onset zone. The most frequent seizure onset localisation is the left temporal lobe (dominant) in right-handed patients.
