During which phase of a generalized seizure does muscular rigidity occur?

The muscular rigidity during a generalized seizure occurs during the tonic phase. In this phase, there is a sustained contraction of the muscles throughout the body, leading to stiffness and rigidity. This phase typically lasts for several seconds and is characterized by a loss of control and responsiveness. The tonic phase is essential in understanding generalized seizures, as it distinguishes it from subsequent phases where other symptoms, such as rhythmic jerking, occur. Additionally, the tonic phase is often the initial phase of a generalized seizure, setting the stage for what follows. Recognizing this helps in anticipating the progression of the seizure and managing the patient's safety effectively.
