Upper limb function rehabilitation training system and method guided by neural circuit

Abstract

A neural circuit-guided upper limb function rehabilitation training system and method are provided. The system includes: a near-infrared neural circuit information acquisition module, which is used to collect near-infrared cerebral blood oxygen signals in corresponding brain regions; an analysis control module, which receives and analyzes near-infrared cerebral blood oxygen signals and various displacement or angle sensor signals to form Neural circuit guidance and brain-limb collaborative rehabilitation control strategy; upper limb exoskeleton module, worn on the user's waist, shoulder, upper limb and hand; display module, used to build a virtual system during the use of the upper limb functional rehabilitation training system The real environment realizes the interaction and visual feedback with the user in the virtual environment. Based on near-infrared cerebral blood oxygen signal parameter monitoring and upper limb exoskeleton multi-degree-of-freedom motion parameter monitoring, the system integrates near-infrared cerebral blood oxygen signal parameters and upper limb multi-degree-of-freedom motion parameter data information to realize comprehensive evaluation of upper limb exercise capacity and provide A variety of training modes to meet various training needs.

Description

technical field [0001] The invention relates to a neural circuit-guided upper limb function rehabilitation training system and method, which are used for upper limb exercise ability evaluation and rehabilitation training. Background technique [0002] The central causes of upper limb movement disorders are mostly stroke and traumatic brain injury. The pathological process mainly involves complete or incomplete damage to the cortex or corticospinal tract, blocking or interfering with the function of sensory motor nerve conduction pathways, resulting in limb movement disorders, especially in Symptoms of unilateral limb dyskinesia are most common. A neural circuit is a complex connection of neurons with different properties and functions in the brain through various forms. Rehabilitation training methods and equipment corresponding to upper limb motor dysfunction need to be based on the characteristics of the brain network, and promote neural circuit reconstruction, functional...

Problems solved by technology

[0003] However, the current field of upper limb motor function rehabilitation lacks an evaluation and training system that integrates interaction, feedback, and assessment training; existing upper limb exoskeleton equipment and products often cannot adapt to the different body size requirements of users, and the control method of the exoskeleton lacks a neural loop. Road-guided and brain-limb collaborative rehabilitation strategy, low rehabilitation efficiency
