Method and device for controlling an artificial orthotic or prosthetic joint

摘要

The invention relates to a device and method for controlling an artificial orthotic or prosthetic joint of a lower extremity, comprising a resistance unit with which at least one actuator is associated, via which the bending and/or stretching resistance is varied depending on sensor data. During the use of the joint, status information is provided via sensors. According to the invention, the resistance is increased in the standing phase or while standing from a starting value depending on the ground reaction force up to a locking point of the joint.

1. A method for controlling an orthotic or prosthetic joint of a lower extremity with a resistance device, which is assigned at least one actuator, the method comprising:
adjusting at least one of a bending and stretching resistance with the at least one actuator in dependence on sensor data pertaining to a state of the joint being provided by way of sensors during use of the joint; increasing the resistance during a standing phase or when standing from an initial value up until a locking of the joint in dependence on a measured ground reaction force; after the resistance is increased, reducing the resistance to the initial value in dependence on at least one of a distance of a ground reaction force from a reference point on a connection part on the joint and a changing of the distance.
