Limb electrical stimulation training system based on joint angle feedback

Abstract

The invention provides a limb electrical stimulation training system based on joint angle feedback, and relates to the technical field of rehabilitation therapy. The limb electrical stimulation training system comprises a joint angle feature acquisition module used for collecting angle parameters of joints in a motion process, a central processor module connected with the joint angle feature acquisition module and used for identifying joint angle characteristics and sending out a control signal, and an electrical stimulation module connected with the central processor module and used for generating an electrical stimulation signal acting on a joint motion muscle group. According to the system, a limb muscle group of motion obstacle is electrically stimulated when a rehabilitation person actively moves to a joint obstacle point, so that the rehabilitation person is helped to go through the obstacle point, the joint motion angle reaches an angle as a normal person, and rehabilitation training is carried out.

Description

technical field [0001] The invention relates to the field of rehabilitation therapy, in particular to a limb electrical stimulation training system based on joint angle feedback. Background technique [0002] Nowadays, there are more and more limb movement dysfunctions caused by nervous system damage, such as stroke, cerebral palsy, and spinal nerve injury, and the limb joint movement ability of the middle-aged and elderly people decreases, and the limb movement ability cannot reach the level of normal people. The impairment seriously affects their daily life. [0003] Limb joint movement disorder is mainly manifested in the movement of the limb joint body to a certain joint angle. Due to the limb movement disorder, the joint will suddenly "stuck" and cannot move, which affects normal sports life. The current limb joint movement rehabilitation training mainly uses electrical stimulation to the movement-impaired limbs and passive rehabilitation exercises to restore the norma...

[0003] Limb joint movement disorder mainly manifests as limb joint body movement to a certain joint angle. Due to limb movement disorder, the joint will suddenly "stuck" and cannot move, affecting normal sports life

The current limb joint movement rehabilitation training mainly uses electrical stimulation to the movement-impaired limbs and passive rehabilitation exercises to restore the normal function of the limbs. However, the traditional electrical stimulation treatment is to continuously stimulate the movement-impaired limbs with a long time of electrical stimulation, which may be harmful to the rehabilitation exercisers. effect, and the electrical stimulation is poorly targeted, inefficient, and the recovery effect is not good
