Problems solved by technology

[0004] However, the current functional magnetic resonance rehabilitation assessment method still has the following main problems: the time resolution of the functional magnetic brain imaging technology is low, the body is often confined to a static state during the test, which is very restrictive, and the requirements for the magnetic field environment higher

Embodiment

[0019] 1. The stroke patients performed the finger-to-nose and heel-to-knee movement experiments. The healthy side and the affected side's upper and lower limbs completed the movement respectively, and the patient independently controlled the start and end of the movement and the rest time between the two tasks;

[0020] Finger-nose task (T1): first place the arms on both sides of the body in a natural state, first lift the upper arm to the front, point the index finger to the tip of the nose, and then put the arm back to the original position to end the task;

[0021] Heel-to-knee task (T2): Sitting posture (sitting on a bed or other platforms), the lower limbs are initially placed horizontally, first lift the exercise leg and place it at the knee of the immovable leg, and then slowly move the exercise leg along the The calf of the stationary leg slides to the original horizontal position to end the task.

[0022] First, explain the whole process and precautions of the experi...

Abstract

The invention discloses a method for extracting exercise ability parameters represented by cerebral cortex hemoglobin information. The steps include: (1) a stroke patient performs a finger-nose and heel-to-knee exercise experiment: the healthy side and the affected side complete the movement of the upper and lower limbs successively, The patient autonomously controls the start and end of the exercise and the rest time between the two tasks; (2) According to the information of the hemoglobin concentration in the cerebral cortex recorded during the exercise and during the rest, analyze the cerebral cortex of the patient before and after recovery from a multi-band perspective The degree of dispersion of oxygenated hemoglobin concentration in each motor function area, as well as the change trend of active frequency bands with positive concentration values ​​and inhibitory frequency bands with negative concentration values; (3) find out the change parameters of brain hemoglobin information space differences and the activation and inhibition The characteristic parameters of the frequency band represent the strength of stroke patients' exercise ability.

Description

technical field [0001] The invention belongs to the motor function rehabilitation evaluation technology, in particular to a method for extracting characteristic parameters representing the strength of motor ability of stroke patients based on cerebral cortex hemoglobin information. Background technique [0002] Stroke has become a common disease among middle-aged and elderly people in my country. With the development of population aging, the morbidity and mortality of stroke have increased greatly. my country is the country with the largest population, and it is also a veritable stroke country. According to the latest survey data, there are about 2.5 million new stroke patients in my country every year. Every 12 seconds, one person suffers from stroke, and more than 1.5 million people die from stroke every year. The prevalence rate of people over the age of 40 in the country has reached 2%. It is currently estimated that there are more than 7 million stroke population in the...
