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

A joint device with an upper part and a lower part which are mounted on each other so as to be pivotable about a pivot axis, a hydraulic unit secured on the upper part and the lower part, and a housing in which a cylinder is arranged. A working piston is arranged in the cylinder and is coupled to at least one spring mechanism which transmits tensile forces and compressive forces and which engages on at least one abutment arranged displaceably inside the cylinder.

Joint device, hydraulic unit and method for controlling a joint device

An actuator-damper unit for use in orthotic or prosthetic devices. The actuator-damper unit includes a housing which may be fastened on the orthotic or prosthetic device and in which a cylinder is formed. A first piston is displaceably mounted in the cylinder and is coupled to a piston rod. The piston rod is disposed, via a first end, on the first piston and may be coupled, via a second end, to the orthotic or prosthetic device. The first piston separates two fluid chambers in the cylinder from each other and forms a piston-cylinder unit, wherein at least one further piston is coupled to the first piston in order to form at least one further, variable-volume fluid chamber.

Actuator-damper unit

A method for controlling an artificial orthotic or prosthetic joint of a lower extremity with a resistance unit 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. A device for carrying out such a method provides bending resistance that is increased or not lowered in the standing phase, when an inertial angle of a lower leg part is decreasing relative to a vertical direction and a front foot under pressure at the same time are identified.

Method and device for controlling an artificial orthotic or prosthetic knee joint

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.

An ankle brace for a prosthetic device includes a prosthetic foot and a lower leg piece. The ankle brace may bridge a gap between the prosthetic foot and the lower leg piece. The ankle brace may include a main member which is made of a flexible material and includes a cavity for accommodating the prosthetic device. At least one reinforcement element may be arranged on the main member which may increase the inherent stability of the ankle brace.
