Abstract

The invention discloses a recognition method for various walking gait adjustment intentions based on hemoglobin information. The present invention is a recognition method of multiple walking gait adjustment intentions based on hemoglobin information, which is characterized in that it includes: performing data preprocessing on the hemoglobin concentration in the cerebral cortex recorded at the time when the walking gait is adjusted; wherein, the walking The hemoglobin concentration in the cerebral cortex recorded at the moment of gait adjustment refers to the "applying near-infrared spectrum brain imaging technology (NIRS) to conduct a test experiment, and the subject completes the corresponding walking gait adjustment task in a fixed area;" Obtained; For the preprocessed cerebral cortex hemoglobin information, the corresponding channels are divided according to the distribution of brain functional areas, and the relevant parameters are calculated and extracted as features; the pattern recognition algorithm is applied to establish four detection models for gait adjustment intentions. Beneficial effects: the present invention uses the near-infrared spectrum brain imaging technology to conduct test experiments simply and conveniently.

Description

technical field [0001] The invention relates to the fields of intelligent walking assistance and rehabilitation training, in particular to a method for identifying various walking gait adjustment intentions based on hemoglobin information. Background technique [0002] In recent years, more and more people are suffering from motor dysfunction. These people are either elderly people with inconvenience in their legs or feet, or some patients who have been disabled after accidents, diseases, and natural disasters. Therefore, more and more scientific researchers are committed to developing ambulatory or rehabilitation training equipment to help these people regain their mobility. As a promising technology, brain-computer interface plays an extensive and profound role in the field of rehabilitation. Through brain-computer interface technology, it is possible to decode the spontaneous movement intentions of the user's brain, and then use these spontaneous movement intentions to ...
