Intelligent rehabilitation robot system for upper limbs in motor imagery and training method thereof

Abstract

The invention relates to an intelligent rehabilitation robot system for upper limbs in motor imagery and a training method thereof, and belongs to the field of motor imagery. The system comprises a motion visual stimulation module, an electroencephalogram acquisition module, an upper computer, and an upper limb rehabilitation movement bracket; the upper computer produces corresponding motion stimulation videos according to a rehabilitation training program, and displays the videos to a user through the motion visual stimulation module; the electroencephalogram acquisition module collects synchronous electroencephalogram signals of the user, carries out an amplification and filtering pretreatment, and transmits the electroencephalogram signals to the upper computer; after receiving the electroencephalogram signals, the upper computer generates rehabilitation training control signals through a feature extraction and pattern classification algorithm and outputs the rehabilitation training control signals to the upper limb rehabilitation movement bracket; the user fastens the limb through a fixing mechanism to the upper limb rehabilitation movement bracket, and the rehabilitation movement bracket receives the training control signals and conducts rehabilitation exercise training on the limb according to the corresponding control signals. According to the intelligent rehabilitation robot system for upper limbs in motor imagery and the training method thereof, the precision of rehabilitation training is improved, and the visual comfort of the user is improved.

Description

technical field [0001] The invention belongs to the field of motor imagery, and relates to a motor imagery upper limb intelligent rehabilitation robot system and a training method thereof. Background technique [0002] Motor Imagery (Motor Imagery, MI) means that the brain only has action intentions but does not perform actual physical actions. Its psychological or thinking cognitive process has a high degree of overlap with the brain areas activated when performing real actions, and the neuron activities in the activated brain areas are highly similar to the information characteristics generated when performing real actions, but there are also Significant difference. Therefore, the combination of motor imagery and rehabilitation training can improve the motor function of patients. Motor imagery therapy has become one of the important new advances in motor rehabilitation therapy for stroke patients, and it is a promising rehabilitation therapy. [0003] When imagining lim...
