Wearable sensing shoe system and gait evaluation method

Abstract

The invention discloses a wearable sensing shoe system and a gait evaluation method. The wearable sensing shoe system comprises a computer, a wireless router, a left foot sensing shoe, a right foot sensing shoe, a left shank motion sensing unit, a right shank motion sensing unit, a left thigh motion sensing unit, a right thigh motion sensing unit and a waist motion sensing unit. The motion sensing units are adhered to lower limbs of shanks, thighs and a waist of a human body and can be used for measuring gesture of each lower limb. The sensing shoes are used for measuring three-dimensional ground counterforce and moments of soles. The motion sensing units and a force sensing unit are used for transmitting data to a local area network of the wireless router through a WIFI module, and a computer is connected to the local area network and is used for receiving data of gestures, forces and moments and carrying out gait evaluation. The system can be used for effectively measuring, analyzing and evaluating the gait of the human body in real time, is easy to wear and use and low in cost and can continuously work in various non-laboratory environments.

Description

technical field [0001] The invention relates to a measurement, analysis and evaluation technology of gait, in particular to a wearable sensing shoe system and an analysis and evaluation method for gait. Background technique [0002] The measurement, analysis and evaluation of gait is an essential work in clinical analysis and rehabilitation as well as in biomechanical research, and there is currently a set of traditional measurement methods that are considered to be reliable standards in the field: a system consisting of multiple infrared high-speed cameras. The motion capture system is coupled with a number of static force plates. The motion capture system sticks markers made of infrared reflective materials on each limb of the experimenter's body, and captures the movement of these markers through an infrared camera to restore the motion of human limbs. The force plate provides the ground reaction force, and the system substitutes the two data into the predetermined human ...

AI Technical Summary

Problems solved by technology

Wearing too many sensors on the body of the testee may affect comfort, and requires high synchronization of data transmission. During gait analysis, unnecessary sensors can be appropriately reduced to obtain enough data with as few sensors as possible

The researchers proposed single pendulum and double pendulum models for the lower limbs, in order to further reduce the number of sensors, and calculate the gait parameters by estimating the posture of other limbs based on the measurement results of some limbs, which is convenient and concise, but the accuracy is reduced to a certain extent
