Hemiplegic patient self-recovery meter based on body mirror image theory

Abstract

The invention discloses a hemiplegic patient self-recovery meter based on a body mirror image theory, and belongs to the field of medical instruments. The hemiplegic patient self-recovery meter comprises a contralateral limb posture signal acquisition device, a signal feature extraction and combination device and an electrical stimulation device, wherein the contralateral limb posture signal acquisition device is used for acquiring the posture information of a contralateral limb of a patient and transmitting the acquired signal to the signal feature extraction and combination device; the signal feature extraction and combination device is used for mapping the posture information of the contralateral limb of the patient from a normal walking gait database according to the received posture information of the contralateral limb and the personal information of the patient, generating a corresponding motion control command, and sending the control command to the electrical stimulation device; and the electrical stimulation device is used for receiving the control command, generating an electrical stimulation signal for stimulating the limb of the patient and making the limb of the patient generate corresponding motion. The recovery meter controls the contralateral limbs of the patient to coordinately move through mirror image copying by taking the posture information of the contralateral limb of the patient, so that effects of balance walking of a hemiplegic patient and reconstruction of a moving function are achieved.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to an autonomous rehabilitation instrument for hemiplegia patients based on the principle of body mirroring. Background technique [0002] Stroke (stroke) is a sudden cerebrovascular circulation disorder. After a stroke, a part of the body often loses movement. Patients with cerebral apoplexy are very prone to relapse, eventually leading to general paralysis and even death. Stroke patients, especially hemiplegic patients who account for a large proportion, have brought heavy burdens to families and society. It is of great economic and social significance to help hemiplegic patients recover basic motor functions and return to normal life. [0003] The functional recovery of most hemiplegic patients is difficult to complete. Although some patients can walk independently, their gait is abnormal, and they cannot return to the normal living environment of the patients before. There are tw...

AI Technical Summary

Problems solved by technology

Both paraplegic patients and hemiplegic patients use functional electrical stimulation walking aids that require stimulation, sensation, feedback, and control. Therefore, there are relatively few studies on more flexible walking, and there is even a lack of medical equipment in this area.
