Functional muscle electrical stimulation-driven exoskeleton walking aiding system

Abstract

The invention relates to a functional muscle electrical stimulation-driven exoskeleton walking aiding system. The system includes a gait detection unit and a signal processing unit; the gait detection unit is used for detecting the motion posture data of different parts of a human body; the signal input end of the signal processing unit is connected with the output end of the gait detection unit; the output end of the signal processing unit is connected with the input end of a functional muscle electrical stimulator used for carrying out electrical stimulation on the corresponding muscles of a user and the input end of a joint locking unit used for locking the joint motion of the user and providing stable support for the limbs and trunk of the user; the output end of the functional muscle electrical stimulator is connected with surface muscle stimulation electrodes which are arranged at the target muscles of the different parts of the user and are used for carrying out electrical stimulation on the target muscles; and the different parts of the user, where the surface muscle stimulation electrodes are located, are connected with the signal collection end of the gait collection system. According to the system of the invention, the muscle motion of the user is stimulated, so that the user can walk in a more natural way, and the weight and energy consumption of the exoskeleton of the user can be decreased, and the endurance ability of the exoskeleton can be enhanced.

Description

technical field [0001] The invention relates to a gait rehabilitation assisting system. In particular, it relates to an exoskeleton walking aid system driven by functional electrical muscle stimulation. Background technique [0002] The main treatment for motor dysfunction or partial body paralysis is rehabilitation medicine, which mainly repairs lesions and damaged sports skeletal muscles and peripheral nerve tissues, or uses sports aids to help and replace paralyzed limb movements, so that users can undergo long-term rehabilitation training Afterwards, a small amount or most of the original motor function can be restored on the basis of physiological "structural rehabilitation" to achieve "functional rehabilitation". With the improvement of medical technology, the development of scientific and technological level and the progress of social civilization, rehabilitation medicine has not only received unprecedented attention (for example, during the implementation of my coun...

Problems solved by technology

At present, most exoskeleton exoskeleton systems use external forces such as hydraulic pressure, air pressure, and motors to move users, which cannot conform to the human body's own musculoskeletal movement methods, and often cause further damage such as muscle atrophy, joint wear, and even fractures.

Moreover, the energy consumption, volume and weight of the above-mentioned power drive components cannot fully meet the daily needs of users.
