Brain-controlled finger training equipment based on music stimulation

Abstract

The invention discloses brain-controlled finger training equipment based on music stimulation. The brain-controlled finger training equipment comprises a workbench, and an electroencephalogram signalacquisition device, an electroencephalogram signal processing device, a VR processing and audio-visual device and a finger training device which are arranged on the workbench; the VR processing and audio-visual device is embedded in the square hole of the workbench, a guide rail is arranged on the workbench, and the finger training device comprises a fingertip-exposed glove fixed to a guide rail adjusting sliding block. The electroencephalogram signal processing device is used for calculating multi-feature fusion data of electroencephalogram in different frequency bands in the process of executing finger action imagination by the subject by utilizing electroencephalogram signals acquired by the electroencephalogram signal acquisition device; the VR processing and audio-visual device is used for generating a finger training task, controlling music and controlling the virtual model according to the multi-feature fusion data; the finger training device drives the fingers of the subject toact according to the multi-feature fusion data so as to complete a training task; music stimulation is fused into training task guidance and brain-computer interaction closed-loop feedback, and efficient brain-computer interaction is promoted.

Description

technical field [0001] The invention relates to the technical field of brain-computer interaction, in particular to a brain-controlled finger training device based on music stimulation. Background technique [0002] Hand function rehabilitation is a problem faced by many brain injury diseases such as stroke. Due to the large range of cerebral cortex mapped by hand movement control, the neural circuits required for fine movements involved in finger function are very complicated, which makes hand function rehabilitation difficult. become a difficult point in rehabilitation treatment. As a multi-mode, multi-feedback rehabilitation intervention technology, brain-computer interaction can identify various thinking activities and movement intentions of the brain, realize the interaction between the brain and the outside world, restore the brain function of the damaged area through neurofeedback, and realize the function of the brain. Nerve remodeling and rehabilitation of limb mot...

Problems solved by technology

[0004] In the above scheme, the visual and auditory prompt information in the guidance process is limited, and the imagination for a period of time is easy to cause brain fatigue, and the brain-computer interaction process is difficult to continue

In addition, in the prior art, there is no direct connection between the motor imagery content prompted by the screen and the brain-controlled object (ie, hand function training equipment) in the actual environment, which also makes it difficult for the subjects to enter the state of motor imagery and perform motor imagery of hand movements
