Brain-control active upper limb medical rehabilitation training system based on wavelet transformation and support vector machine recognition

Abstract

The invention discloses a brain-control active upper limb medical rehabilitation training system based on wavelet transformation and support vector machine recognition, and the system comprises an EEG controller, brain-control software downloaded into a computer, and myoelectric biofeedback equipment. The EEG controller, the brain-control software and the myoelectric biofeedback equipment are connected through a 3G or 4G wireless signal. The EEG controller comprises a wearable EEG sensor and a wireless communicator. The myoelectric biofeedback equipment comprises a host and an electrode line which is electrically connected with the host and can be connected with a human body. Based on the above, the invention also discloses a brain-control active upper limb medical rehabilitation training system based on wavelet transformation and support vector machine recognition. The system collects a brain signal of a patient, carries out the analysis of features, recognizes the intention of upper limb movement of the patient with the loss of motor function, controls the myoelectric biofeedback equipment to stimulate the muscle of the upper limb of the patient to complete the corresponding upper limb movement, and effectively improves and recovers the motor function of the patient.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a brain-controlled active upper limb medical rehabilitation training system based on wavelet transform and support vector machine identification. Background technique [0002] Upper limb rehabilitation is a complex and systematic subject. First of all, the causes of upper limb injuries are different. One is physical injury, such as contusion and fracture caused by external force; the other is neurological injury, such as stroke, cerebral infarction, etc. Upper extremity injuries caused by neurological injuries; for the former, better results can be achieved through manual massage recovery, drug recovery, and instrument massage; for the latter, the current traditional method is to use electrical stimulation rehabilitation programs, electrical stimulation rehabilitation programs It refers to the use of direct installation of electrodes on the upper limbs for periodic ele...

[0002] Upper limb rehabilitation is a complex and systematic subject. First of all, the causes of upper limb injuries are different. One is physical injury, such as contusion and fracture caused by external force; the other is neurological injury, such as stroke, cerebral infarction, etc. Upper extremity injuries caused by neurological injuries; for the former, better results can be achieved through manual massage recovery, drug recovery, and instrument massage; for the latter, the current traditional method is to use electrical stimulation rehabilitation programs, electrical stimulation rehabilitation programs It refers to the use of direct installation of electrodes on the upper limbs for periodic electrical stimulation. It is a passive rehabilitation program. The patient's brain does not participate in the rehabilitation process, so the rehabilitation effect is relatively limited.
