Multiple axial force platform array and human walking gait information gaining method

Abstract

A platform array of multiple axial forces is composed of the installing tracks, 1-4 platforms of 6 axial forces, surface covering layer, network interface module, and network data acquisition card. A method based on said platform array for testing, analyzing and evaluating the balance power, coordinating power and nerve system of human body is also disclosed, which features that the information about the force / force moment of said platform array is acquired by computer, where they are processed to obtain the information about walking state.

Description

[0001] Field [0002] The invention relates to the field of medicine, in particular to a system and method for testing, analyzing and evaluating gait dynamics information and body balance and coordination in the process of human walking in sports biomechanics and neurology, that is, a multi-axis force platform An array and a method for acquiring walking gait information of a human body. technical background [0003] Gait is the posture of the human body when walking. It refers to the process of moving the body in a certain direction through a series of continuous activities of the hip, knee, ankle and toe. The normal gait has stability, periodicity and rhythm, direction sex, coordination, and individual differences. Gait research has become one of the hotspots in rehabilitation medicine and human sports biomechanics research, and it is an important parameter used to evaluate the human body's own exercise ability and disease diagnosis. [0004] When people have diseases, ther...

Problems solved by technology

[0013] From the above analysis, it can be seen that there are many types of gait analysis systems in foreign countries at present, but they are mainly based on kinematics, and the gait information test not only includes kinematics information, but more importantly, dynamics. Although foreign CODA-III, SELSPOT-II, ELLTE and VICON also include force plates, they do not have the function of obtaining gait time parameters, space-time parameters and mechanical parameter information at the same time.

However, the platform proposed by Tsinghua University in China that uses a three-dimensional force platform to obtain dynamic information can only obtain information about the magnitude and direction of the force, but cannot obtain the point of action of the force during the walking process, making the relevant step distance, step length, pace, etc. information not available
