A Type Of Seizure: Tonic seizures are short seizures consisting of a sudden increase in the tone of muscles throughout the body leading to a stiff appearance. They are commonly associated with lennox-gastaut syndrome and are readily identified with EEG monitoring during an episode.

Tense muscles: In a "tonic" seizure, the tone is greatly increased and the body, arms, or legs make sudden stiffening movements. Consciousness is usually preserved. Tonic seizures most often occur during sleep and usually involve all or most of the brain, affecting both sides of the body. If the person is standing when the seizure starts, he or she often will fall.
