Title:
GAIT ANALYSIS METHOD, SYSTEM, AND DEVICE FOR IMPROVING DYSBASIA
Document Type and Number:
WIPO Patent Application WO/2024/060955
Kind Code:
A1
Abstract:
The present invention provides a gait analysis method, a system, and a device for improving dysbasia. The method comprises: acquiring three-axis acceleration data and three-axis angular velocity data collected by an inertial sensor, and acquiring pressure data collected by a pressure sensor; performing quaternion operation on the three-axis acceleration data and the three-axis angular velocity data to obtain a three-axis acceleration and a three-axis Euler angle corresponding to a ground coordinate system; identifying a swing state and a static state of feet according to the three-axis acceleration data and the pressure data; performing analysis according to the three-axis acceleration, the three-axis Euler angle, and the swing state and the static state of the feet to obtain gait parameters related to a linear walking process, a turning process, an included angle between the feet and the ground, and foot tremor; and uploading the gait parameters to a server. The present invention can provide objective and comprehensive exercise data of the feet of a patient to provide an objective basis for formulating a rehabilitation treatment plan and evaluating rehabilitation efficacy, and collection of the exercise data is not limited by a site, which can reduce the burden of a doctor and a patient.
