Convulsions describe intense, uncontrollable spasms of the large muscles in the body, such as those that exist in the arms, legs and abdomen. These muscles contract without any voluntary action by the patient, causing their limbs and body to move violently and uncontrollably. Convulsions can be the result of a number of disorders, such as a neurological disease, or by intense pain.

It is difficult for physicians to treat convulsive patients as the uncontrolled flailing of the arms poses a serious risk of injury. As such, convulsive patients often have to be restrained or sedated.
