Generalized tonic-clonic seizures (GTC or also called grand mal seizures) are characterized by five distinct phases that occur. The body, arms, and legs will flex (contract), extend (straighten out), and tremor (shake), followed by a clonic period (contraction and relaxation of the muscles) and the postictal period.
