Rehabilitation training feedback method and system based on near-infrared brain imaging

Abstract

The invention discloses a rehabilitation training feedback method and system based on near-infrared brain imaging, and the method comprises the following steps: S1, obtaining a brain blood oxygen signal from a near-infrared spectrum image, analyzing an activation region of the cerebral cortex of a trainee, monitoring the brain region activation level and muscle activation degree in a motion state, and obtaining a brain blood oxygen signal; outputting near infrared data; s2, setting target training data, receiving near-infrared data output by the near-infrared brain imaging acquisition module, comparing the near-infrared data with the target training data, analyzing action differences of trainees, outputting comparison data, and judging whether the comparison data and the target training data are fitted or not; and S3, when the comparison data and the target training data are fitted, outputting a voice or vibration prompt. Therefore, according to the rehabilitation training monitoring feedback system based on the near-infrared brain function imaging system, the near-infrared brain function imaging system is used for evaluating the brain activation degree, the muscle activation degree and the muscle fatigue degree and conducting motion feedback and posture correction on the trainee, and the rehabilitation training monitoring feedback system can be used for assisting the trainee in completing rehabilitation training with high quality.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training, in particular to a method and system for feedback of rehabilitation training based on near-infrared brain imaging. Background technique [0002] The near infrared spectroscopy (NIRS) region is located between 780-2526 nm, which is the absorption spectrum generated by the frequency doubling and group frequency vibration of C-H, N-H, O-H, S-H and other groups in organic compounds, and organic compounds are in this range. Both have absorption, but the absorption spectrum is different. Modern near-infrared spectroscopic analysis technology can realize non-destructive analysis, and can qualitatively or quantitatively analyze several or even dozens of substances or concentration data of a sample at the same time within tens of seconds or even a few seconds. The operation is simple, accurate and sensitive. No pollution, no damage, a wide range of applications (solid, liquid, Jiaodong-li...
