Upper limb muscle rehabilitation training device based on electrical stimulation induction

Abstract

The invention discloses an upper limb muscle rehabilitation training device based on electrical stimulation induction, and the device comprises a first body part which comprises a forearm section, a wrist section and a palm section, the forearm section and the palm section are respectively provided with a stimulating electrode, the forearm section is connected with the wrist section, and the wrist section is connected with the palm section; the second body part corresponds to the forearm section, and a stimulating electrode is arranged on the second body part; the first body part is hinged to the second body part, a locking mechanism is arranged between the first body part and the second body part, and the locking mechanism is used for locking the opening and closing state between the first body part and the second body part. The upper limb muscle rehabilitation training device disclosed by the invention can induce generation of coordinated active contraction in the training process, so that the hands complete coordinated grasping and stretching actions to promote completion of the training actions, and the effects of maintaining nervous muscle excitability and preventing or delaying muscle atrophy are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an upper limb muscle rehabilitation training device induced by electrical stimulation. Background technique [0002] Stroke, also known as stroke, cerebrovascular accident, is an acute cerebrovascular disease, which is a disease of brain tissue caused by sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to vascular blockage. Complications associated with nerve damage caused by acute stroke or C4-7 spinal cord injury can cause movement disorders in the upper and lower limbs, facial muscles, and lower part of the tongue muscle, which are manifested in the inability of muscles to achieve voluntary contractions, resulting in the inability of the human body to complete certain specific actions. For example, the upper limbs cannot perform grasping and stretching. That is, when normal muscles contract, action potential signals are...

AI Technical Summary

Problems solved by technology

Complications associated with nerve damage caused by acute stroke or C4-7 spinal cord injury can lead to movement disorders of upper and lower extremities, facial muscles, and lower parts of tongue muscles. For example, the inability to grasp and extend the upper body

That is, when the muscles of normal people contract, the action potential signal is generated by the central nervous system, transmitted to the peripheral nerve, and then transmitted to the muscle to be contracted through the synapse. For patients with complications, due to the interruption of the central nervous system pathway, the signal cannot be transmitted to the corresponding muscle group, so normal motor function cannot be achieved

[0003] Functional electrical stimulation uses low-frequency current pulses to stimulate muscles that have lost nerve control, causing muscle contraction, promoting nerve regeneration and recovery of conduction function, so as to help restore the function of the affected limb. The existing functional electrical stimulation structure is relatively simple, only Can perform simple muscle stimulation actions, but cannot help the upper limbs to complete grasping and stretching actions
