Abstract

The invention discloses a hemoglobin information based recognition method for multiple walking gait adjusting intents. The hemoglobin information based recognition method for the multiple walking gaitadjusting intents, disclosed by the invention, is characterized by comprising the steps: carrying out data preprocessing on cerebral cortex hemoglobin concentrations recorded at walking gait adjusting moments, wherein the cerebral cortex hemoglobin concentrations recorded at the walking gait adjusting moments are obtained in a manner that a testing experiment is performed by using a near infraredspectrum brain imaging technique (NIRS) and testees finish corresponding walking gait adjusting tasks in a fixed region; subjecting preprocessed cerebral cortex hemoglobin information to corresponding channeling according to distribution of cerebral functional areas, and calculating and extracting relevant parameters as characters; modeling a detection model for four kinds of gait adjusting intents by applying a pattern recognition algorithm. The method has the beneficial effect that the testing experiment is performed by using the near infrared spectrum brain imaging technique, and thus, themethod is simple and convenient.

Description

technical field [0001] The invention relates to the field of intelligent walking aid and rehabilitation training, in particular to a recognition method for various walking gait adjustment intentions based on hemoglobin information. Background technique [0002] In recent years, more and more people suffer from motor dysfunction. These people are either elderly people with inconvenient legs or feet, or some patients who have experienced disabilities after accidents, diseases, and natural disasters. Therefore, more and more scientific researchers are devoting themselves to developing walking aids or rehabilitation training equipment to help these people regain mobility. As a promising technology, the brain-computer interface plays an extensive and profound role in the field of rehabilitation. Through the 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 ...
