Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Aiming at the rehabilitation of upper limb motor function of paralyzed patients, the present invention proposes a hybrid brain-computer interface upper limb training rehabilitation robot system based on Motor Imagery (MI) and steady-state visual evoked potential (SSVEP) EEG.

[0035] Noun English abbreviation:

[0036] Steady-State Visual Evoked Potential (SSVEP), Motor Imagery (Motor Imagery, MI), Brain Computer Interface (Brain Computer Interface, BCI), Wavelet Transform (Wavelet Transform), Feature Extraction (Feature Extraction), classification Algorithm (Classification algorithm)

[0037] Common Spatial Pattern (CSP), Support Vector Machine (Support VectorMachine, SVM), Canonical Correlation Analysis (CCA)

[0038] The technical problems to be solved by the present invention are: 1) an analysis method of EEG signals; 2) distinguishing EEG ...

Abstract

The invention discloses a control system and method for an upper limb rehabilitation training robot based on a brain-computer interface. The system comprises a visual stimulation module and an electroencephalogram signal acquisition module, the electroencephalogram signal acquisition module communicates with an electroencephalogram signal analysis module, the electroencephalogram signal analysis module sends a control signal to an upper limb exoskeleton control system after online analysis and processing, and a visual stimulation module communicates with the upper limb exoskeleton control system through a protocol; a steady-state visual evoked potential controls the start and stop of upper limb exoskeletons, and motion imaging controls rotation of upper limb exoskeleton upper arms and flexion and extension of elbows. Through combination of a brain-computer interface technology and a robot technology, a patient can actively participate in and freely master the training time, the enthusiasm of the patient can be mobilized, and the control accuracy is improved while the fatigue of training of the patient is reduced at the greatest extent. For patients with complete paralysis, the repair or reconstruction of a damaged motor conduction pathway can be promoted through motion imaging therapy.

Description

technical field [0001] The invention relates to the technical field of a control method for an upper limb rehabilitation training robot, in particular to a control system and method for an upper limb rehabilitation training robot based on a brain-computer interface. Background technique [0002] In recent years, with the gradual aging of our society, stroke has become one of the biggest threats to the health of middle-aged and elderly people. According to statistics, there are as many as 2 million stroke patients in China every year, and the disability rate reaches 75%. Most of these patients are accompanied by symptoms of upper limb hemiplegia and left over with different degrees of upper limb motor dysfunction. Daily life is extremely painful and inconvenient, and it also brings a heavy burden to the family and society. Medical theory and clinical medicine have proved that in addition to early surgical treatment and necessary drug treatment for patients with upper limb he...
