Alignment of the above-knee prosthesis.
Alignment will be discussed in terms of what happens as a result of specified changes in the relative positions of the prosthetic components. As a person walks on his prosthesis the conditions which predominate at various stages can be identified: (a) the conditions of no-load, or swing phase, (b) the conditions under which there is full loading or stance phase, (c) the capacity to control the ...
متن کاملEvaluation of the Polycentric above Knee Prosthesis
The optimal design of human lower limb prostheses, in particular of knee devices, is fundamental in order to restore the lost functionality and aesthetic aspect of the amputee’s locomotion. Among all knee devices, the four-bar linkage is still the most widespread mechanism, since, despite its simplicity, it allows the prosthesis to be sufficiently stable and, at the same time, to replicate the ...
متن کاملIntelligently Controlled Above Knee (A/K) Prosthesis
In existing advanced A/K prostheses the sti ness and damping at the prosthetic knee joint are applied by hydraulic or pneumatic cylinders. The pre-set parameters being constant, are not optimal during the whole gait cycle, for di erent walking speeds, and sudden posture irregularities. The complexity of normal and prosthetic gait leads to the development of 'soft' control (non-analytic) governe...
متن کاملThe TC double socket above-knee prosthesis.
The conventional total contact suction AK prosthesis presents several disadvantages, such as difficulty in wearing the socket in a sitting position, difficulty in obtaining a favourable disposition of the stump soft tissues in the socket and difficulty in avoiding stump perspiration problems. In an attempt to solve these disadvantages, a new AK prosthesis with a thermoplastic double socket was ...
متن کاملA Functional Above-the-Knee Prosthesis
The widely used above-the-knee prosthesis is composed of a quadri lateral muscle-contour, wooden thigh socket, a knee mechanism, a wooden shank, a SACH foot, and a suitable pelvic suspension. This type of pros thesis has met with considerable success in most patients, but it is expensive and not all geriatric patients can wear it. A so-called temporary limb—a modified long brace with a leathe...
