Waxy Flexibility or Flexibilitas Cerea

Waxy flexibility, also known as cerea flexibilitas, is a catatonic motor symptom in which the patient's limbs can be placed in any position in which the position is maintained as if the person is made of wax. The examiner can move the patient's limbs even with the slightest pressure. An associated symptom is a "psychological pillow" in which the patient has raised neck and sleeps as if his neck lies over an invisible pillow.
