Embodiment

[0066] Example: see figure 1 , figure 2 , A gait analysis system, including an intelligent terminal with Bluetooth communication function and two signal acquisition systems. The signal acquisition system includes a carrier 1, a pressure sensor 2, an acceleration sensor, an angular velocity sensor, an MCU and a battery; the carrier 1 The shape is consistent with the shape of the insole.

[0067] The pressure sensor 2 adopts a thin-film resistive pressure plate, and there are several; in the specific implementation process, the pressure sensor 2 is densely distributed in the place where the force is large, and the pressure sensor 2 is sparsely distributed in the place where the force is small. 1 Corresponding to the pressure sensors on the heel, metatarsophalangeal joints and thumbs, the distance between the pressure sensors 2 is 4mmX4mm, the distance between the pressure sensors 2 corresponding to the arch of the carrier 1 is 20mmX20mm, and the distance between the pressure sensor...

Abstract

The invention discloses a gait analysis system and method. The gait analysis system comprises an intelligent terminal and two signal collection systems, and each signal collection system comprises a carrier, a pressure sensor, an acceleration sensor, an angular velocity sensor, an MCU and a battery. The MCUs are in wireless connection with the intelligent terminal through Bluetooth communication. The analysis method comprises the steps that firstly, collected pressure signals are filtered twice; secondly, initial grounding signal detection is conducted, an initial pressure threshold Th is obtained, then middle threshold detection is conducted, and finally a stand ending threshold is judged; thirdly, a rectangular Cartesian coordinate system is built; fourthly, the point location (x, y) of the center of a current pressure is solved; fifthly, a half sole varus-valgus coefficient and a heel varus-valgus coefficient are calculated; sixthly, the symmetry SI is judged; seventhly, the coefficient of variance CVt is judged; eighthly, in-toe gaits or out-toe gaits are judged; ninthly, the foot arch index AI is judged. By means of the system and method, gait information can be more comprehensively and accurately analyzed out.

Description

Technical field [0001] The invention relates to the technical field of gait analysis, in particular to a gait analysis system and an analysis method. Background technique [0002] Gait is the external manifestation of human body structure and function, motor regulation system, behavior and mental activity while walking. However, dysfunction of a certain system or some aspects can cause abnormal gait. According to the survey, 50%-60% of light exercise people suffer from knee injuries of varying degrees due to incorrect gait during exercise (collectively referred to as running injuries); abnormal walking posture during development directly affects the bones, legs and even spine of children during growth Development; abnormal gait has suggestive significance for certain diseases, such as diabetic foot, lower extremity arthritis, lower extremity muscle weakness. Through gait analysis, the prevention and auxiliary treatment of certain diseases can be achieved. [0003] Gait analysis i...
