Motor imagery therapy device based on brain-computer interface, and use method thereof

Abstract

The invention discloses a motor imagery therapy device based on a brain-computer interface, and a use method thereof. The device comprises a visual stimulation screen, an electroencephalogram collection system, a brain-computer interface module and a control system, wherein a patient stares at a target presented on a feedback interface on the visual stimulation screen to carry out corresponding wrist motor imagery; the electroencephalogram collection system comprises an electrode cap, an electrode and an electroencephalogram collection module; the brain-computer interface module is used for preprocessing an electroencephalogram signal and carrying out feature extraction and classification; and the control system is used for controlling the analysis of an instruction and sending a control command. By use of the device, a brain-computer interface technology is applied to the motor imagery therapy, hemiplegic patients can be effectively assisted in improving motor skills and emotion control abilities, a damaged motor conduction path is accelerated to be repaired or reconstructed, the formation of a normal motor reflex arc can be effectively accelerated, meanwhile, medical care personnel can be assisted in visually observing whether the patient receives the effective motor imagery therapy or not, and the initiative of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of physical therapy for hemiplegic patients, in particular to a brain-computer interface-based motor imagery therapy device and a method for using the same. Background technique [0002] Brain-computer interface technology is a technology established by the human brain and computers or other electronic facilities, based on EEG signals, which can realize information exchange and exchange with the outside world without relying on peripheral nerves and muscle tissue. At present, the most involved fields in the field of brain-computer interface technology are roughly divided into three parts: entertainment, recovery and enhancement. Because the first two are the closest to reality, there are many researchers, especially the brain-computer interface technology in the field of rehabilitation. One of its important uses is to provide a new way of rehabilitation training for patients with normal thinking but severe m...

Problems solved by technology

However, in the actual clinical physical therapy process, although the patient still has a certain motor imagery ability, the accuracy and timeliness are affected, which is manifested as the inability to perform precise motor imagery.
