Control means is provided which is pivotally coupled to the first member and to the pivotal connection of the two links to move the two links and hence the second member relative to the first member. The first member may be coupled to a person to allow the prosthesis in one embodiment to serve as an arm and in another embodiment to serve as a leg of a person.
In another embodiment, the first member may be coupled to the upper portion on an arm to allow the prosthesis to serve as the lower portion of the arm. In still another embodiment, the first member may be coupled to the upper portion of a leg to allow the prosthesis to serve as the lower portion of the leg.
