Abstract: The invention relates to a method for operating an orthopedic device which supports or replaces a first body part of a wearer and has at least one controllable actuator, wherein the method includes a) determining a chronological profile of at least one parameter, which allows for a conclusion to be made regarding a movement status of the wearer, from measurement values of at least one sensor; b) detecting the movement status from the at least one determined chronological profile; and c) controlling the at least one controllable actuator depending on the identified movement status, wherein at least the chronological profile of at least one parameter of a second body part of the wearer is also used to identify the movement status.
