AI Technical Summary
The prior art is difficult to effectively monitor and analyze gait abnormalities, especially at high frequency recordings in daily life.
By arranging three pressure sensors on the sole, a rectangular coordinate system is established, the center position of the sole of the sole is recorded at high frequency, and the direction and degree of deviation from the reference are used as monitoring objects.
It realizes efficient monitoring and analysis of gait abnormalities, and can accurately capture changes in the foot pressure center at high frequency records in daily life, thereby providing effective health monitoring.
Abstract
Description
Technical Field
[0001] The invention belongs to the field of human motion measurement and is a gait monitoring method. Background Art
[0002] The center of pressure refers to the intersection of the line of action of the resultant force of the pressure on the plane and the plane. Summary of the invention
[0003] The present invention is a gait monitoring method, which is simple and easy to use. Its characteristics are: within a period of time, the position of the plantar pressure center is recorded at high frequency, their center is basically consistent with the plantar pressure center during this period, and the direction and degree of its deviation from the benchmark are used as the monitoring object, the benchmark is the plantar pressure center when the monitored person stands normally, and the method for determining the plantar pressure center is to set three pressure measurement points on the sole of the foot, establish a rectangular coordinate system on the plane determined by them, and obtain their total pressure center coordinates according to their pressure and coordinates, so that it is basically consistent with the plantar pressure center coordinates. DETAILED DESCRIPTION
[0004] Example 1 In order to measure the plantar pressure center, we developed a special shoe with three pressure sensors arranged on the sole, so that the contact surface between each sensor and the sole is basically in the same plane, and the pressure center of each contact surface is basically consistent with the geometric center. A rectangular coordinate system is established on the plane where the contact surface is located. According to the pressure and center coordinates of each contact surface, their total pressure center coordinates can be obtained, so that it is basically consistent with the plantar pressure center coordinates. Over a period of time, it is used to record the position of the plantar pressure center at high frequency. Their center is basically consistent with the plantar pressure center during this period of time. The direction and degree of its deviation from the benchmark are used as the monitoring object. The benchmark is the plantar pressure center when the monitored person is standing normally.
