Brain-controlled gait training system and method for Parkinson's disease

Abstract

The invention relates to a brain-controlled gait training system and method for Parkinson's disease. The system comprises an electroencephalogram signal acquisition device, an electroencephalogram signal analysis device, an eye movement data acquisition device, an eye movement data analysis device, a limb movement acquisition device, a task paradigm processor and a presentation device, wherein theelectroencephalogram signal analysis device calculates related electroencephalogram characteristic data by utilizing electroencephalogram signals acquired by the electroencephalogram signal acquisition device; the eye movement data analysis device is used for calculating and recording related eye movement characteristic data by utilizing eye movement data acquired by the eye movement data acquisition device; the limb movement acquisition device acquires limb movement data of a patient; and the task paradigm processor performs comprehensive processing according to the characteristic data and the limb movement data, and processed data is output by the presentation device. Through rhythmicity prompt-based gait training task paradigm guidance and closed-loop feedback of electroencephalogram and eye movement characteristics, the patient completes imagination and movement training of coordinated movement of upper and lower limbs and realizes strengthening of limb movement and rhythmicity prompt information in the brain, so the walking function of the patient with Parkinson's disease is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a brain-controlled gait training system and method for Parkinson's disease. Background technique [0002] Parkinson's disease is a degenerative disease of the central nervous system characterized by resting tremor, muscle rigidity, slowness of movement, and gait disturbance. Among them, gait disorder is the main cause of patients' imbalance and falls, and it manifests differently in different stages of Parkinson's disease. In the early and middle stages of Parkinson's disease, gait disturbance is mainly manifested in decreased arm swing, decreased gait speed and stride length, and there is no obvious specificity. As the disease progresses, in the late stage of Parkinson's disease, more serious and characteristic gait disturbances such as flustered gait and frozen gait appear. The interaction between the basal ganglia and the secondary motor cortex is an important part of motor...

Problems solved by technology

However, these existing systems or methods lack the active participation of the patient's brain and the closed-loop interaction with the outside world in the training process, and lack of consideration for the gait training in the early and middle stages of Parkinson's disease, which makes the effect of gait training and the persistence of the effect There are still some limitations
