| 20080288086 | Method for Adjusting a Leg Prosthesis and Verifying the Adjustment, and Apparatus for the Measurement of Forces or Moments in a Leg Prosthesis - The invention relates to a method for verifying the adjustment of a prosthetic knee joint that connects a lower leg shaft, to which a prosthetic foot can be fastened, to an upper leg shaft in a manner allowing the lower leg shaft to rotate about a joint axis in order for the prosthetic knee joint to be fastened to an end of the upper leg, the upper leg shaft being movable relative to the joint axis. A knee moment and an axial force that is effective in the lower leg shaft are measured via sensors when the prosthesis is utilized. A resulting force vector with a point of attack on the upper leg shaft is calculated from said variables. The horizontal distance and the position of the resulting force vector relative to the joint axis are also calculated, and a verification is made whether and by how much the resulting force vector lies in front of or behind the joint axis on the sagittal plane. The invention also relates to an apparatus especially for carrying out the inventive method, in which connecting means are mounted on an upper prosthetic joint part so as to be movable on the sagittal plane between said upper part and an upper leg shaft while devices for detecting knee forces or moments are mounted on a terminal adapter or the upper part. | 11-20-2008 |
| 20090076618 | JOINT DEVICE - A joint device for an orthoses or prostheses includes an upper part, a lower part mounted on the upper part in such a way as to turn about a pivot axis, and braking means that brakes or blocks a pivoting movement of the lower part relative to the upper part. The braking means includes a spiral spring arranged between two contact surfaces and is mounted such that it can be braced in the direction of the contact surfaces about a rotation axis parallel to the pivot axis. | 03-19-2009 |

| 20110071452 | KNEE ORTHOSIS, AND METHOD FOR CONTROLLING A KNEE ORTHOSIS - The invention relates to a knee orthosis and a method for controlling a knee orthosis comprising a thigh structure that has a fastening structure to be fixed to a thigh, a lower leg structure which is pivotally coupled to the thigh rail by means of a joint mechanism and has a fastening structure to be fixed to a lower leg as well as a foot piece for supporting a foot, and an actuator device between the thigh structure and the lower leg structure. The fastening points of the actuator on the thigh structure and lower leg structure and the center of rotation of the joint mechanism form a triangle. The fastening points are arranged on the structures in such a way that the connecting line between the fastening points extends perpendicular to a connecting line between a fastening point and the center of rotation in an angular position of the knee in which the lower leg is bent at an angle ranging from 0° to 90° relative to the thigh. | 03-24-2011 |
