Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1 to Figure 4 As shown, the lower limb prosthetic gait test system of the present invention consists of a simulated leg, a power source, a transmission device, and a measurement and control system.

[0017] The simulated legs include torso 1, thigh 2, calf 3, foot plate 4, hip joint 5, knee joint 6, thigh damping structure 14, calf damping structure 15, two sets of counterweight structures 9, power source includes drive motor 7; measurement and control system includes Four-corner displacement sensors 13, a data acquisition module 10, a motion control card 12, and a computer processing system 11.

[0018] The computer processing system 11 is fixed on the outer box 8 on the ground through a bracket, and the four-corner displacement sensors 13 are respectively located at the two hip joints 5 and the two knee joints 6 to collect the ...

Abstract

The invention relates to a lower limb prostheses gait testing system, consisting of a simulation leg, a power source, a transmission device and a measurement and control system; the measurement and control system comprises a four-corner displacement sensor, a data collecting module, a motion control card and a computer processing system; wherein, the computer processing system is fixed on an external box body on the ground surface by a bracket; the four-corner displacement sensor is respectively arranged at two hip joints and two knee joints and used for collecting and simulating the joint angle change of the gait, and transmits the collected signal to the computer processing system by a data collecting module; furthermore, by the software of the control system and the collecting system, the collected gait joint angle data in the whole gait period when human walks normally is used as the control signal; the power source is controlled by a motion control card; the output of the power source drives the motion of the simulation leg by the transmission device, thus realizing the simulation of the normal human walking gait. The system of the invention can basically simulate the normal gait of the human body, can provides feasible testing platform for the objective evaluation of the prostheses performance.

Description

technical field [0001] The invention relates to a prosthesis performance testing system device, in particular to an objective prosthetic performance evaluation device. Background technique [0002] The data from the second national sample survey on the disabled shows that there are currently 24.12 million physically disabled people in my country. In order to bring this part of people back into society, it is necessary to comprehensively improve the technical level of prosthetics, improve the functions of prosthetics, and improve the rehabilitation level of patients. In the process of prosthetic development, the most direct experimental method is to study and test its performance, but it is difficult to carry out the experiment when the prosthesis has not yet entered the practical stage, and different people have different opinions on the same prosthesis. Evaluation is somewhat subjective. Therefore, it is an inevitable trend to evaluate the compensatory function of prosthet...
