What is a common symptom during the clonic phase of a seizure?

In the clonic phase of a seizure, one of the hallmark symptoms is the occurrence of rhythmic jerking movements of the body. This phase follows the tonic phase, where the muscles exhibit extreme rigidity. The clonic phase is characterized by these rapid, involuntary muscle contractions, which can also lead to a loss of bladder control, resulting in involuntary urination. This symptom is often seen due to the intense muscle contractions and the body's involuntary relaxation response.

While altered mental status may occur before or after a seizure, it is not specific to the clonic phase. Cool, moist skin can happen during various medical emergencies, but it is not a defining feature of the clonic phase itself. Therefore, the presence of involuntary urination is a direct consequence of the intense physical activity and loss of control during this specific phase of a seizure, making it the most appropriate answer.
