Method and device for controlling an artificial orthotic or prosthetic joint

摘要

The invention relates to a method and device for controlling an artificial orthotic or prosthetic joint of a lower extremity having a resistance device to which at least one actuator is associated, via which the bending and/or stretching resistance is changed depending on sensor data. During the use of the joint, status information is provided via sensors. During use of the joint, status information is provided via sensors, wherein a cyclic movement different from walking is determined and the resistance is reduced for the duration of the cyclic movement.

1. A method for controlling an artificial orthotic or prosthetic joint of a lower extremity, the method comprising:
providing a resistance device, at least one actuator, and sensors; controlling the resistance device via the actuator to change at least one of a flexion resistance and an extension resistance provided by the resistance device in response to sensor data, with status information being made available via the sensors, the sensors generating the sensor data during use of the joint; determining with the sensors maxima and minima of at least one of a joint angle and a joint-part inertial angle of the artificial orthotic or prosthetic joint during a time period; measuring time intervals between the maxima and minima of the at least one of a joint angle and a joint-part angle; identifying a recurring pattern of the time intervals within the time period; associating the recurring pattern with a cyclic profile for cycling; automatically reducing at least one of the flexion resistance and the extension resistance in the joint for a duration of the cyclic profile.
