Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as figure 1 Shown, a kind of gait detection analysis method comprises the following steps:

[0039] 1) Signal collection: The six-axis acceleration sensor collects at least six types of signals of the linear acceleration and angular acceleration of the foot in the three directions of space X, Y, and Z, and the X, Y, and Z directions are the set directions.

[0040] 2) Refer to figure 2 , locate the complete landing point: set the initial threshold to 0.5G, the square wave signal to 0, amplify the original signal by 3 times, eliminate interference, and perform low-pass filtering on the signal data, or use the pass-band filtering method to use the y-axis Acceleration generates a square wave signal. If the square wave is detected as a falling edge, start to detect the maximum value of the x-axis angular velocity, and judge whether t...

Abstract

The invention discloses a gait detection and analysis method and a device thereof, and the device comprises a carrier, a data collector, a microprocessor, and a battery. The method is characterized byanalyzing and processing the acquired data, calculating corresponding data, transmitting the data to an intelligent terminal, and executing the gait detection and analysis method; the method comprises the following steps: 1) collecting signals; 2) positioning a complete landing time point; 3) carrying out gait detection; 4) performing single-step signal division; 5) performing step number statistics; 6) calculating the size of the angle; 7) determining a walking mode, (8) determining a landing mode, and (9) judging pronation and extorsion; and (10) determining in-toe gait and out-toe gait. The gait can be conveniently, rapidly and accurately detected and analyzed by the method and the device, and objective gait analysis basis and effect evaluation after rehabilitation treatment, correction or exercise improvement are provided for doctors, exercise coaches and users.

Description

technical field [0001] The invention relates to the technical field of step counting, in particular to a gait detection and analysis method and device. 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. According to the survey, 50%-60% of people who exercise lightly suffer from different degrees of knee injuries (collectively referred to as running injuries) due to incorrect gait during exercise; abnormal walking posture during development directly affects children's bones, legs, and even spine during growth Development; Abnormal gait is suggestive of certain diseases, such as diabetic foot, arthritis of the lower extremities, and muscle weakness of the lower extremities. The prevention and auxiliary treatment of certain diseases can be realized through...
