Problems solved by technology

[0003] The traditional rehabilitation training methods based on stroke are mainly carried out manually or with the help of simple equipment to drive the affected limbs. This type of rehabilitation method requires many medical staff and consumes a lot of physical energy. It is difficult to ensure the intensity and durability of rehabilitation training, and is subject to Influenced by the therapist's subjective factors, it is difficult to ensure the initiative, objectivity, accuracy and consistency of rehabilitation, which limits the further optimization of rehabilitation training methods and the improvement of rehabilitation effects
Especially in recent years, the cost of personnel has been rising continuously, which makes the rehabilitation cost of traditional training methods continue to increase, which brings great economic and living pressure to patients' families and society.

Abstract

The invention provides an upper limb active rehabilitation method and device based on brain electricity and functional electrical stimulation, and relates to the technical field of rehabilitation robots. After the EEG signal is amplified and preprocessed, feature extraction is performed on the preprocessed EEG signal to obtain a feature vector for classifying left and right-hand motor rehabilitation intentions; Rehabilitation intent; use the FES system to perform functional electrical stimulation on the corresponding parts of the rehabilitated object through the rehabilitation intent; the functional electrical stimulation performed by the FES system forms a plastic rehabilitation feedback on brain function. The invention realizes the recognition of the active rehabilitation intention of the rehabilitation object through the EEG signal, and performs functional stimulation according to the rehabilitation intention through the FES system, so as to achieve better active, objective and accurate rehabilitation effect.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to an upper limb rehabilitation method and device based on brain electricity and functional electrical stimulation. Background technique [0002] Stroke is one of the main causes of uncontrollable upper limb motor function, and about 1 / 3 of stroke patients will remain with varying degrees of disability. In the acute phase of stroke, the impaired motor function of patients may recover partly spontaneously, while the possibility of spontaneous recovery of impaired motor function in patients with stroke in the chronic phase is greatly reduced. [0003] The traditional rehabilitation training methods based on stroke are mainly carried out manually or with the help of simple equipment to drive the affected limbs. This type of rehabilitation method requires many medical staff and consumes a lot of physical energy. It is difficult to ensure the intensity and durability of reh...
