Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1-6 As shown, a gait analysis method analyzes the data collected and transmitted by the signal acquisition system. The acquisition system is a six-axis acceleration sensor that at least collects acceleration data in the three directions of space X, Y, and Z. The X , Y, and Z directions are the set directions, and the specific analysis process is as follows:

[0026] 1) Refer to figure 2 , locate the time point of complete landing: set the initial threshold to 0.5G, the square wave signal to 0, amplify the original signal by 3 times, eliminate interference, perform low-pass filtering on the signal data, and use the y-axis acceleration to generate a square wave signal, if When the square wave is detected as a falling edge, start to detect the maximum value of the x-axis angular velocity, and judge whether the maximum val...

Abstract

The invention discloses a gait analysis method. A six-axis acceleration sensor at least collects acceleration data in the three directions of space X, Y, and Z; the steps of the judging method are as follows: 1) positioning the time point of complete landing; 3) single-step signal division; 4) calculate the size of the angle; 5) judge the way of landing; 6) judge the internal rotation and external rotation of the foot; 7) judge the running mode. This method can realize real-time detection and analysis of the user's gait through real-time collection and algorithm processing of various parameters based on the user's feet during walking or exercise, and the analysis process is convenient and fast with high accuracy, which is conducive to the early detection of athletes. Make corrections.

Description

technical field [0001] The invention relates to the technical field of gait analysis, in particular to a gait analysis method. Background technique [0002] Gait is the external manifestation of human body structure and function, motor regulation system, behavior and psychological activities during walking. However, dysfunction of one of these systems or certain aspects can cause gait abnormalities. Foot pronation itself is a normal movement, a series of cushioning movements that the foot naturally produces to prevent damage to the inner arch of the foot. However, long-term under-pronation or over-pronation may cause running injuries. Pronation of the foot disrupts the normal weight-bearing path, causing the leg to overturn inward. Excessive pronation of the foot is poor form that can lead to discomfort and injury. External rotation is the opposite of internal rotation, where the foot rolls outward. Common conditions caused by excessive internal and external rotation of ...
