Another condition is hysterical attack, which is generally a pseudo-convulsion that occurs when a person with certain personality characteristics is angry or emotionally agitated in the presence of other people, and the hand can be in the shape of a chicken’s claw, which is generally more obvious by suggestion, and can be relieved by verbal suggestion or symptomatic treatment by others or doctors.
