Upper limb rehabilitation evaluation system and method based on surface electromyography and motion modules

Abstract

The invention provides an upper limb rehabilitation evaluation system and method based on surface electromyography and motion modules. The system comprises a host computer, a single chip microcomputercontrol end, a surface electromyography collection module and a motion parameter collection module, wherein the surface electromyography collection module comprises two electrodes, a low-pass filtering circuit, a common-mode rejection module, an amplification circuit and a subtraction circuit which are connected sequentially; the host computer comprises a display; the subtraction circuit and themotion parameter collection module are connected with the single chip microcomputer control end; the single chip microcomputer control end is connected with the host computer. Through the adoption ofthe upper limb rehabilitation evaluation system and method based on the surface electromyography and motion modules, motion parameters and surface electromyography signals of a trainee in the motion process can be collected automatically for analysis, smoothness, intensity and muscle function of upper limb motion are evaluated, evaluation information is fed back to a tester in real time, so that much time and labor for subjective evaluation are reduced, and evaluation actions are simplified.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an upper limb rehabilitation evaluation system and method based on surface electromyography and motion modules. Background technique [0002] The recovery of upper limb motor function in stroke patients mainly depends on rehabilitation therapy. In rehabilitation treatment, only when the therapist correctly understands the lack of kinetic energy of the patient's upper limbs and gives corresponding evaluations can he orientate the individualized rehabilitation goals, and then perform appropriate treatment, master the correct rehabilitation process, and achieve improvement. The ultimate goal of rehabilitation efficiency. Correct evaluation of upper limb motor dysfunction in stroke patients is the key to upper limb rehabilitation. At present, the methods for evaluating upper limb motor function mainly include: medical scale method, parameter comparison method, Fitts law method (Fitts...

AI Technical Summary

Problems solved by technology

In the existing rehabilitation treatment, the doctor evaluates the motor function of the patient through the scale method. This method is inefficient, has too many movements, and is greatly influenced by the doctor's subjectivity, which limits the accuracy of the evaluation.
