Hand function rehabilitation training device and method

Abstract

The invention discloses a hand function rehabilitation training device and method. The device comprises a controller, a gas drive module, a myoelectricity collection module, an electrical stimulationmodule, soft gloves connected with the gas drive module, and an electrode slice group I connected with the electrical stimulation module, wherein the gas drive module, the myoelectricity collection module and the electrical stimulation module are connected with the controller; the soft gloves are provided with pneumatic telescoping assemblies; the controller calculates a hand movement posture of ahealthy side by collecting a hand muscle electric signal of the healthy side, so that the electrical stimulation module and the gas drive module are controlled to achieve mirror image training of thefingers and the wrist of an affected side, and comprehensive recovery of the hand function of the affected side is accelerated; a five-position electromagnetic switch valve group is adopted in the gas drive module, so that the fingers of the affected side are in different stretching and bending states in one training action, and different training requirements of patients are met; and a gas pressure sensor is adopted in the gas drive module to detect the gas pressure intensity changes in the pneumatic telescoping assemblies, and a movement intention of the fingers is recognized based on an ideal gas principle, so that power-assisted training of the hand is achieved.

Description

technical field [0001] The invention belongs to the field of upper limb exoskeleton rehabilitation robots, and more specifically relates to a hand function rehabilitation training device and method. Background technique [0002] Nowadays, the aging of the social population is increasing, and the number of people with hemiplegia caused by stroke and other diseases is increasing. At the same time, the number of people with impaired limb motor function caused by accidents such as production accidents and traffic accidents is also increasing year by year. These patients are often unable to take care of themselves due to limb motor dysfunction, which brings a lot of burden to the family and society. Robot-assisted rehabilitation training can save a lot of manpower and material resources, and can conduct real-time quantitative evaluation of the patient's rehabilitation level, and carry out training step by step according to the patient's rehabilitation status. [0003] Most of th...

Problems solved by technology

[0006] The purpose of the present invention is to provide a hand function rehabilitation training device and method, which solves the problems that the hand function cannot be fully restored due to the inability to perform synchronous mirror image training on the fingers and the wrist, and the inability to perform biological treatment on the wrist. Rehabilitation equipment lacks the problem of lack of active movement training by detecting changes in hand movement postures to identify hand movement intentions
