Evaluation method and system based on near-infrared brain functions and gait parameters

Abstract

The present invention discloses an evaluation method and system for near-infrared brain functions and gait parameters. The evaluation method and system are used for evaluating correlation between thebrain functions and gait parameters. The system comprises a near-infrared brain function information acquisition module, a gait parameter acquisition module, an evaluation and analysis module and a correlation analysis module; the near-infrared brain function information acquisition module is used for acquiring brain blood oxygen signals; the gait parameter acquisition module is used for acquiringgait data; the evaluation and analysis module is used for analyzing differences of the near-infrared brain functions and gait parameters of people with cognitive impairment and normal people according to the brain blood oxygen signals acquired by the near-infrared brain function information acquisition module and the gait data acquired by the gait parameter acquisition module; and the correlationanalysis module is used for calculating correlation between the near-infrared brain functions and the gait parameters of the two groups of people, and conducting analysis to obtain the gait parameters reflecting changes of the brain functions.

Description

technical field [0001] The invention belongs to the field of rehabilitation aids, in particular to an evaluation method and system based on near-infrared brain function and gait parameters. Background technique [0002] Mild cognitive impairment (MCI) is a transitional state between normal aging and early dementia. The annual conversion rate of MCI patients to AD is 8%-15%, and MCI is an appropriate stage for preventive intervention. However, almost one-third of MCI patients remain clinically stable and even return to normal cognitive function after initial diagnosis, highlighting the danger of MCI patients being viewed as a homogeneous population. Therefore, accurate and timely assessment of MCI is of great significance to prevent disease progression. However, there is still a lack of accurate and objective early assessment techniques for MCI at home and abroad. [0003] The assessment scale is a commonly used MCI assessment method at present. Commonly used assessment s...
