a psychopathological symptom consisting in the pathologically long-term preservation of a posture given from the outside (like a wax figure). This condition is characterized by the suspension of voluntary movements and the disappearance of sensitivity. E. Bleuler, a Swiss psychiatrist, described the condition as follows: “Patients do not make movements of their own free will; They can be given any position, and no matter how uncomfortable it is, they will stay in it for a very long time.”
