The invention relates to a method for controlling at least one actuator () of an orthopedic device () with an electronic control device (E), which is coupled to the actuator () and at least one sensor () and which has an electronic processor (μC) for processing sensor data (s), wherein at least one state machine (SM) in which states (z) of the orthopedic device () and state transitions of the actuator () are determined is stored in the control device (E), wherein a classifier (K) in which sensor data (s) and/or states (z) are automatically classified within the scope of a classification method is stored in the control device (E), wherein the state machine (SM) and the classification method are used in combination and, on the basis of the classification and the states (z), a decision is made about the manner of activating or deactivating the actuator () as a control signal.

Method for controlling at least one actuator of an orthopedic device, and orthopedic device

The invention relates to an orthopaedic joint comprising an upper part and a lower part pivotably mounted thereon and a resistance device which is located between the upper part and the lower part and provides resistance against a pivoting movement about a pivot axis, and has a resistance adjusting device coupled to a control device which is coupled to at least one sensor such that the resistance can be adjusted by means of the control device on the basis of sensor data transmitted from the at least one sensor to the control device, a function is stored in the control device in which the joint is locked against pivoting in at least one direction in accordance with the sensor data, the function can be activated for locking and deactivated for unlocking on the basis of the sensor data.

Orthopaedic joint and method for controlling same

A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.

Method for controlling the standing-phase damping of an artificial knee joint

A method for controlling an artificial orthotic or prosthetic knee joint, on which a lower-leg component is arranged and with which a resistance device is associated, the bending resistance (R) of which resistance device is changed in dependence on sensor data that are determined by at least one sensor during the use of the orthotic or prosthetic knee joint, wherein a linear acceleration (a) of the lower-leg component is determined, the determined linear acceleration (a) is compared with at least one threshold value, and, if a threshold value of the linear acceleration (a) of the lower-leg component is reached, the bending resistance (R) is changed.

Method for controlling an artificial orthotic or prosthetic knee joint

An orthopedic technical device having a top part and a bottom part, which are connected to each other by at least one joint device so as to be pivotable about a joint axis, and at least one attachment device with which the orthopedic technical device can be fixed to a limb. The orthopedic technical device also has an actuator, which is fixed to attachment points on the top part and the bottom part and influences a pivoting of the top part relative to the bottom part, wherein the orientation of the bottom part can be adjusted relative to the limb which is fixable to the upper part.

Orthopaedic technical device controlled by an actuator and method for controlling same

A method for controlling a damping modification in an artificial knee joint of an orthosis, an exoskeleton, or a prosthesis. The artificial knee joint has an upper part pivotally connected to a lower part A resistance unit is secured between the upper part and the lower part in order to provide a resistance against a flexion or extension. The resistance unit is paired with an adjustment device to modify the resistance when a sensor signal of a control unit paired with the adjustment device activates the adjustment device. The flexion resistance is reduced for the swing phase. A curve of at least one load characteristic is detected when walking or standing; a maximum of the load characteristic curve when standing is ascertained; and the flexion damping is reduced to a swing-phase damping level during the standing phase when a threshold of the load characteristic below a maximum is reached.

Method for controlling a damping modification

A method for controlling an artificial orthotic or prosthetic knee joint, on which a lower-leg component is arranged and with which a resistance device is associated, the bending resistance of which resistance device is changed in dependence on sensor data that are determined by at least one sensor during the use of the orthotic or prosthetic knee joint, wherein a linear acceleration of the lower-leg component is determined, the determined linear acceleration is compared with at least one threshold value, and, if a threshold value of the linear acceleration of the lower-leg component is reached, the bending resistance is changed.

A method for controlling a change of resistance in an artificial joint of an orthosis, an exoskeleton or prosthesis of a lower extremity. The artificial joint has an upper part and a lower part which are secured on each other so as to be pivotable about a pivot axis, a damper unit is secured between the upper part and the lower part in order to provide a resistance to flexion or extension of the artificial joint, and the damper unit is assigned an adjusting mechanism via which the resistance is changed when a sensor signal of a control unit assigned to the adjusting mechanism activates the adjusting mechanism. The resistance is changed as a function of the position and/or length of the measured or calculated leg tendon and/or the time derivatives thereof.
