Abstract: The invention relates to a method for controlling an orthotic or prosthetic joint of a lower extremity with 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 the sensors. The sensor data are determined by at least one device for detecting at least two moments or a moment and a force. The sensor data of at least two determined values are linked by means of a mathematical operation and at least one auxiliary variable is thus calculated, on which the control of the bending and/or stretching resistance is based.

Abstract: A hip joint prosthesis includes connection means for securing the hip joint prosthesis to a securing device and to an artificial leg, and a control unit for controlling an extension movement in the hip joint and for controlling the step length of the artificial leg.

Abstract: The invention relates to a method for controlling an orthopedic joint of a lower extremity in at least one degree of freedom by means of an adjustable actuator for adjusting an orthopedic apparatus to walking situations that differ from walking on a plane. Said orthopedic apparatus comprises top connecting means to a limb and an orthopedic element that is hingedly arranged distal to the connecting means.

Abstract: The invention relates to the control of a passive prosthetic knee joint with adjustable damping in the direction of flexion such that a prosthetic unit attached to the knee joint can be adapted for climbing stairs.

Abstract: A torque sensor for measuring a torque at a predetermined location of a structural element, in particular of a prosthesis, can be arranged outside the measurement location by virtue of the fact that it is constructed as a sensor structure (13, 13?, 23) that forms a virtual pivot axis (16, 16?) outside the sensor. The sensor structure is provided with measurement transducers (29) which detect deformations of the sensor structure (13, 13?, 23) and are used to determine a torque about the virtual pivot axis (16, 16?). A preferred application for the torque sensor is its incorporation in a prosthesis for the purpose of controlling an artificial joint.

Abstract: Prosthetic or orthotic joint with at least two joint segments that are mounted rotatably to each other around a joint axis, and a pivotal piston mounted in torque-proof fashion in one of the upper or lower joint segments. The pivotal piston is received in a displacement chamber containing a fluid, with the pivotal piston subdividing the displacement chamber into two partial chambers that are connected with each other via a connecting channel at least across a selected pivoting angle range of the pivotal piston. At least one flow section determining contour is formed between the pivotal piston and one selected displacement chamber wall, which is in a fluidic connection with the connecting channel and the displacement chamber across a selected rotation angle. The contour also provides a varying free flow section for the passage of the fluid dependent on the rotational position of the pivotal piston.

Abstract: The invention relates to a hip joint which has an attachment for an artificial leg and which, in order to permit a largely natural walking movement, has the following features: a front link (5) and a rear link (6) are articulated at their respective upper sections, via a first joint connection (1) and a second joint connection (2), respectively, to a front section and a rear section, respectively, of an upper transverse link (7), and are articulated at their respective lower sections, via a third joint connection (3) and a fourth joint connection (4), respectively, to a front section and a rear section, respectively, of a lower transverse link (8); the first and third joint connections (1, 3) together have at least five degrees of freedom; the second joint connection (2) is a hinge pin which with its pivot axis (2a) is approximately perpendicular to the sagittal plane and has one degree of freedom; the fourth joint connection (4) has a pivot axis (4a) with mediolateral and anteroposterior inclination and with

Abstract: An arrangement for receiving and setting a wheel axle for a drive wheel of a wheelchair, with an adapter (1) for adjusting the wheel camber, characterized in that the adapter (1) has a receiving bore (2) for the wheel axle, extends longitudinally approximately in the direction of this bore (2) and, to set the camber, can be attached removably to the wheelchair frame (9) in the desired position and is able to slide crosswise to the wheelchair frame (9) on a path running in a segmental arch.
