Abstract: A method for carrying out a functional analysis on a person equipped with an artificial extremity having adjustable settings. The method includes the steps of providing a sensor assembly configured as a replacement for a part of the artificial extremity and installing the sensor assembly in place of the part. Forces, accelerations and/or torques are then measured with the sensor assembly during use of the artificial extremity by the person and the settings of the artificial extremity are optimized based on these measurements. The sensor assembly is removed and the replaced part is installed back into the artificial extremity, while retaining the optimized settings. In one embodiment, the artificial extremity is a leg prosthesis having an artificial knee joint with a rotational adaptor mounted above it. The sensor assembly then replaces the rotational adaptor.

The first and second connections are connectable to the first and second parts of the transmitter, respectively. The electromechanical sensor elements convert mechanical parameters into electrical parameters. The first flange surrounds the first connection and originates at the first connection. The second flange is aligned substantially parallel to the first flange. The second connection is arranged on the second flange and has a first surface and a second surface. The plurality of struts are substantially perpendicular to the first flange and connect the first flange to the second flange.

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: A lower back orthosis includes a bandage designed to surround the lower back of a patient and a support device connected to the bandage. The support device is formed by a plurality of finger-shaped rods connected directly to one another. The finger-shaped rods are oriented in a longitudinal direction of a spinal column when positioned on a patient.

Abstract: A lower back orthosis bandage includes a middle piece having a first flat end and a second flat end, a first end piece having a mouth-like end and a second end piece having a mouth-like end. The first end piece is releasably connected to the first flat end of the middle piece by the mouth-like end of the first end piece. The second end piece is releasably connected to the second flat end of the middle piece by the mouth-like end of the second end piece. The first end piece and the second end piece are connectable to each other to close the bandage.

Abstract: An orthopaedic aid for an extremity includes at least one adjustable element for positioning the orthopaedic aid relative to the extremity. The detector arrangement includes a plurality of indicators for indicating torques generated by the detector arrangement. The detector arrangement is positionable such that a section of the detector arrangement is torque-free. The detector arrangement generates torques arising in two opposite directions in a measuring plane in response to deviations from a stable load position.

Abstract: Parking brake, in particular for a wheelchair, with a pressing element (10) articulated by a pivoting lever (8) coupled to a retainer (12) mounted to the wheelchair frame. The pivoting lever (8) is tiltable by swiveling a hand brake lever (7) into an engaged position, in which the pressing element (10) exerts force against a wheel (2). In addition, a resetting-force-applying element is set under a pre-load against the pivoting lever (8) to return the pivoting lever (8) to a neutral position when the hand brake is released, characterized by the fact that the resetting-force-applying element is a flexible bendable element (6) formed from a frame cover (5) fastened to the retainer (12).

Abstract: A running wheel arrangement for a wheelchair that can be driven by electric motor including a frame and wheels releasably connected.

The wheel is inserted into the adapter and mechanically lockable via a locking device which includes: a pivot plate fastened to the driving motor; the wheel is mounted rotatably in a pivot plate via an axle bolt; a link bolt pointing in the direction of travel arranged in the adapter; a cross-sectionally U-shaped tab arranged at one end of the pivot plate; the tab being placed onto the link bolt such that the wheel is shifted by means of a pivoting movement toward the frame until a locking bolt provided on the pivot plate engaged on the locking bush arranged on the adapter, and the wheel is locked mechanically with respect to the frame via the locking bolt and the locking bush.

Abstract: The invention relates to a tilt-stable rotating joint suitable for technical orthopedic components, including a forked external joint part with two limbs whose parallel inner walls pointing towards each other form a slit of a given width and are provided with flush continuous holes. A flat inner joint part protrudes into the slit and a continuous hole, and a shaft arrangement protruding through the continuous holes forms a rotating bearing surface with a cover surface. The tilt-stability is increased because the shaft arrangement is formed by sections protruding from the inner joint part, having an external diameter corresponding to the internal diameter of the continuous holes of the limbs. Stability is also increased by the fact that the shaft arrangement is rotationally fixed to the inner joint part and sliding bearings are formed between the walls of the continuous holes of the limbs and the sections of the shaft arrangement.

Abstract: A joint orthosis including an upper member, a lower member operably connected to the upper member by one or more swivel axes at a joint mechanism, and a pad attached to the joint mechanism and positioned between the joint mechanism and the body part, wherein the joint mechanism includes a clip connection for securing the pad to the joint mechanism. The upper and lower members include a means for attaching the joint orthosis to a body part of a user, such as an extremity. The clip connection connects to a coupling element that is one or more of an adapter or pad bracket positioned between the joint mechanism and the pad. The pad, pad bracket and/or adapter are configured to cover over the joint mechanim and the pivot axis. The upper and lower members can include teeth that interlock with each other in order to form a synchronized pivot movement.
