Abstract: A prosthesis or orthesis for a member of a human body, comprising limb-forming components which components are connected by pivoting couplings and at least one first element whose ends are coupled with components that are distinguishable from each other, wherein the first spring element spans at least two pivoting couplings.

Abstract: The invention relates to a corset for the treatment of a patient suffering from a back complaint, such as scoliosis, comprising a lower part to be supported by the hip, and an upper part to be fitted around the patient's chest. There is a flexible coupling provided to connect the lower part and the upper part. Both the lower part and the upper part are provided with an adjustable springy element to enable the lower part and the upper part to apply a pressure force on the patient's body.

Abstract: The invention relates to a prosthesis comprising first and second prosthesis parts connected for mutual movement which are characterized by a locking element for locking respectively releasing the prosthesis parts relative to each other. The parts are preferably connected for mutual movement by an artificial joint comprising a first and a second joint part. The locking element is spring biased and co-acts in a locked position with a recess in one of the joint parts, whereby tilting of the locking element is bounded, and which in the released position is substantially freely tiltable. The prosthesis can be further provided with a pin for actively placing the locking element out of the active reach of the recess. One of the two prosthesis parts connected for mutual movement is formed with a cup so that the prosthesis can be fixed to the remaining part of an amputated extremity.
