Rehabilitation monitoring system and method based on near-infrared brain imaging

Abstract

The invention discloses a rehabilitation monitoring system and method based on near-infrared brain imaging, and the system comprises a near-infrared brain imaging collection module which is used for collecting a brain blood oxygen signal, analyzing an activation region of the cerebral cortex of a trainee, and monitoring the motion characteristics of muscle groups in a motion region of the cerebral cortex; the near-infrared peripheral nerve monitoring module is used for distinguishing nerves of each link and monitoring the activity of peripheral nerves of the nerves of each link; the muscle activity detection module is used for judging the activity degree of the muscle according to the blood oxygen content of the muscle; and the data processing and analyzing module is used for summarizing and analyzing the data, identifying weak muscle groups of the spine and monitoring the motion state of core muscle groups in real time. The brain function imaging dynamic spectrum during movement is combined, cerebral cortex activity information characteristics corresponding to movement are refined, muscle group activity is accurately monitored and evaluated, a specific cerebral cortex area is monitored so as to evaluate the brain activation degree, the muscle activation degree, the muscle fatigue degree and the like, and real-time monitoring of rehabilitation training is achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation tools, in particular to a near-infrared brain imaging-based rehabilitation monitoring system and method. 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-like substances can be...

Problems solved by technology

[0005] The existing rehabilitation training and evaluation systems based on brain functional imaging technology are widely used in the rehabilitation training of stroke patients, and the use of traumatic diseases is relatively rare. Currently, the known rehabilitation training techniques for trauma and bone and joint chronic diseases are mostly combined. The exoskeleton mechanical cooperative therapy is carried out without core training for specific muscle groups. The current literature shows that the active movement and passive movement stimulation in the brain function imaging system will show different image features on the brain function imaging, and the excessive reliance on external Although skeletal-assisted rehabilitation can achieve isotonic contraction exercise rehabilitation of limb muscles, the isometric contraction training of muscles cannot be well trained, resulting in the lack of targeted training for muscle strength

[0006] To sum up, near-infrared brain functional imaging technology is a technical means that can be used to monitor muscle movement by monitoring changes in cerebral blood flow. Currently, the existing rehabilitation training assistance and evaluation systems based on brain functional imaging lack the ability to target weak muscle groups. The characteristic analysis of brain function imaging training, in addition, the combination of brain function imaging technology and exoskeleton technology lacks muscle strength training, which is suitable for rehabilitation training for patients with brain dysfunction and abnormal nerve conduction pathways, but not suitable for bone Rehabilitation exercises for patients with joint diseases
