Upper limb active rehabilitation method and device based on electroencephalogram and functional electric stimulation

Abstract

The invention provides an upper limb active rehabilitation method and a rehabilitation device based on electroencephalogram and functional electric stimulation, and relates to the technical field of rehabilitation robots. The upper limb active rehabilitation method comprises the following steps: under a circumstance of stimulating left and right hands, acquiring electroencephalogram signals basedon left and right hand motor imagery in accordance with stimulation paradigm; amplifying and pre-processing electroencephalogram signals, and implementing characteristic extracting on the pre-processed electroencephalogram signals, so that characteristic vectors which are used for classifying left and right hand motion rehabilitation intentions are obtained; inputting the characteristic vectors into a classifier and classifying the characteristic vectors, so that left / right hand motion rehabilitation intentions; implementing functional electric stimulation on corresponding parts of a rehabilitation object by virtue of an FES system in accordance with the rehabilitation intentions; and implementing functional electric stimulation by virtue of the FES system, so that plastic rehabilitation feedback to brain functions is formed. According to the upper limb active rehabilitation method and device provided by the invention, recognition of active rehabilitation intentions of rehabilitation objects is achieved through the electroencephalogram signals, and functional stimulation is implemented by virtue of the FES system in accordance with the rehabilitation intentions, so that a better active, objective and accurate rehabilitation effect can be achieved.

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...

[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.
