Carlos Morra and Ernst Franzek: Psychopathological Symptoms
Definition: Maintenance of imposed posture; limbs remain in position they are placed regardless of how unnatural the position is for a long time and not only for a few minutes (Petho and Ban 1989).
Exploration: The examiner raises the patient’s arms or moves one of the patient’s legs into an uncomfortable forced position. To qualify for “waxy flexibility” there need to be a decreasing passive resistance to moving the limbs into the unnatural position from the beginning to the end and the imposed posture needs to be maintained for a long period of time and not only for minutes (Fink & Taylor 2003).
