Abstract

The invention discloses a near-infrared-based multi-band physiological signal feedback system and a using method thereof. The system comprises a physiological signal acquisition module used for acquiring cerebral blood oxygen signals of cerebral cortex of a subject in real time; a data preprocessing module which is used for preprocessing the original data acquired by near infrared spectrum equipment in real time so as to remove noise components in the signals; a multi-band analysis module which is used for extracting multi-band physiological signal intensity index parameters from the preprocessed cerebral blood oxygen signals; a physiological signal feedback module which is used for performing real-time data visualization processing on the intensity index parameters extracted by the multi-band analysis module and feeding back the processed intensity index parameters to the subject; and a display module which is used for displaying the feedback process of the physiological signal feedback module. Based on the near infrared spectrum technology, the physiological activity and nerve activity of the brain in the specific frequency band are adjusted through a five-frequency-band physiological signal feedback method, and the brain dysfunction patient is helped to be trained and rehabilitated better.

Description

technical field [0001] The invention belongs to the field of rehabilitation aids, and in particular relates to a near-infrared-based multi-band physiological signal feedback system and a use method thereof. Background technique [0002] Rehabilitation training is an important means of rehabilitation for patients with brain dysfunction, and it is of great significance for the improvement and recovery of patients with motor dysfunction caused by brain function damage. Feedback training techniques have broad applications in understanding brain function and brain disease. In the process of feedback training, the multi-dimensional cerebral cortex activity information is monitored through the physiological signal acquisition equipment, and the internal neural functions and mechanisms of the brain are used to realize the self-regulation of physiological activities and neural activities. Feedback training techniques enable the decoding of the brain's neural activity patterns to opt...
