Embodiment Construction

[0036] The specific implementation of the present invention will be described below in conjunction with the embodiments and the accompanying drawings.

[0037] Such as figure 1 As shown, a gait acquisition and neuromuscular electrical stimulation system based on multi-sensor fusion includes a sensor module, a stimulation module, a data transmission module (wireless transmission) and a host computer module.

[0038] The sensor module of the present invention includes surface electromyography sensors, laser ranging sensors and inertial sensors. Different sensors can collect different signals, which are then used for subsequent data fusion. In the present invention, it can simultaneously collect surface electromyographic signals of lower limbs, Euler angles, angular velocity, acceleration, and the straight-line distance between the ankle and the ground, so as to realize the acquisition of real-time gait information. Specifically, the surface electromyography sensor is used to co...

Abstract

The invention discloses a gait acquisition and neuromuscular electrical stimulation system based on multi-sensor fusion, which belongs to the field of rehabilitation engineering. It includes a myoelectric signal acquisition sensor module, a stimulation module, a wireless transmission module and a host computer module, and the sensor module includes a surface myoelectric sensor, a laser ranging sensor and an inertial sensor. The present invention can carry out real-time wireless collection and transmission of surface electromyographic signals of lower limbs, Euler angle, angular velocity, acceleration and the distance from ankle to ground during walking, and send them to the upper computer module for calculation and processing. The present invention can obtain and reproduce the electrical stimulation mode and parameters of the functional movements of the lower limbs of healthy individuals, and study the control sequence of fine movements; it can also be used for users with gait disorders, and cooperate with ankle-foot orthoses to realize self-optimization by using myoelectricity and kinematics information Control the stimulation program to achieve the purpose of individualized motor function reconstruction. The invention can perform wireless reception and processing of data based on the mobile terminal, which increases portability and practicability.

Description

technical field [0001] The invention relates to the field of medical rehabilitation engineering, in particular to a gait acquisition and neuromuscular electrical stimulation system based on multi-sensor fusion. Background technique [0002] The lower extremity exoskeleton robot has a very broad application prospect in assisting the elderly and the disabled. Only by correctly identifying the movement pattern of the lower limbs can an effective control strategy be adopted. Therefore, lower limb gait pattern recognition has become one of the key technologies for lower limb exoskeleton robots. [0003] The walking of the human body is a very complicated process, and the comprehensive analysis of various signals is required to accurately identify the gait. [0004] Surface electromyography (SEMG) is an electrical signal generated with myoelectric contraction, which can be collected on the surface of the skin through electrodes. By decoding the surface EMG signals of the lower l...
