Passive Controller Design for Swing Phase of a Single Axis Above-Knee Prosthesis
In this research we design a passive controller for an above knee prosthesis. The controller is a linear spring and damper for swing phase motion, parameters of which determined via optimization of adjustment of the prosthesis shank motion with a desired shank angle trajectory comes from experimental data. In this way, we exerted a certain thigh motion, hip movement included, into the system as...
متن کاملHRC adjustable pneumatic swing-phase control knee.
Since 1972 the Hyogo Rehabilitation Centre has been developing a variable-resistance-type pneumatic control device, the HRC Adjustable Pneumatic Swing-Phase Control Knee. Successful field tests have been carried out on 20 cases with Model IV since 1973 with only a limited number of mechanical troubles. This paper introduces the HRC adjustable pneumatic swing-phase control knee with follow-up st...
متن کاملAlignment 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...
