Abstract

The invention provides a calculation method of gait spatio-temporal parameters based on a portable gait analysis system, including calculation of time parameters and calculation of space parameters. The speed and position information obtained by integrating and calculating the sensor data contains errors accumulated over time, which improves the accuracy of gait parameter calculation and solves the problem that the plantar pressure analysis method cannot calculate gait space parameters, such as stride, walking The beneficial technical effect of the problem of distance, walking speed.

Description

technical field

[0001] The invention belongs to the technical field of gait analysis, in particular to a calculation method of gait space-time parameters based on a portable gait analysis system. Background technique

[0002] Gait analysis (gait analysis) is a technology that obtains and analyzes gait parameters by observing or collecting the posture of the human body during walking. Common gait parameters include spatial parameters (stride length, step length, step width, etc.), Time parameters (standing / swing period, single step time, stride frequency, etc.), and the symmetry of the left and right feet of these parameters, the stability of long-term data, etc. Gait analysis plays a very important role in sports, medical rehabilitation, etc., and has been widely used and studied. Traditional gait analysis equipment and methods are generally three-dimensional gait analysis instruments used in large hospitals and rehabilitation centers. Such equipment has the following disad...
