Application of mão reabilitação dispositivo in hemiplegic mão reabilitação - Acidente Vascular Cerebral Center

Statistics show that after acidente vascular cerebral, only 15% of pacientes pode recuperar about half of their mão função, and only 3% of pacientes pode recuperar more than 70% of their original mão função. It has become a major trend in the reabilitação field to explore eficaz reabilitação tratamento methods and promote the recuperação of pacientes' mão função. Therefore, the combination of task-oriented training and emerging reabilitação tecnologia has gradually become an indispensable reabilitação tratamento tecnologia for mão função reabilitação. The emergence of mão função reabilitação robôs has brought novo ideas for the reabilitação of mão função after acidente vascular cerebral.

This article will briefly share the intelligent soft mão reabilitação robô and interface cérebro-computador mão-função robô.

Intelligent soft mão reabilitação robô

The intelligent soft mão função reabilitação robô combines robótico tecnologia and neuroscience, and pode fornecer various training modes such as passive, assistance, resistance, bilateral mirror and active games. It is a mão função reabilitação robô that fully covers the period from soft paralisia to reabilitação. In the process of robô-assisted training, bilateral mirror terapia and motor imagery were combined to realize the integrated tratamento of central intervention and peripheral intervention.

With the intelligent soft mão reabilitação robô, pacientes pode stimulate the motor cortex of the brain through multi-modal stimulation through visual, auditory and tactile sensory stimulation to form a closed-loop reabilitação training and melhorar the paciente's willingness to actively participate in mão função reabilitação training to promote the recuperação of the paciente's motor função. At the same time, in bilateral mirror terapia, the healthy mão drives the affected mão to exercise, which pode further melhorar the neuroplasticity of the brain.

The addition of novo methods faz the closed-loop reabilitação model of central-peripheral-central a clinically important reabilitação theory. Central intervention pode promote the activation of the corresponding funcional brain areas of the brain and melhorar brain neuroplasticity. Peripheral intervention continuously strengthens the positive feedback of sensory and motor control modes to the brain center. The combination of the two modes promotes the remodeling of brain função in acidente vascular cerebral pacientes. The interface cérebro-computador has become the best choice to realize the closed-loop reabilitação mode.

Interface Cérebro-Computador training will give pacientes VR visual and auditory dual stimulation, so that they pode perform motor imagination of the affected mão movements, so as to control the exoesqueleto reabilitação robô to complete the mão grasping and opening movements. Through interface cérebro-computador training, pacientes repeatedly imagine the grasping and opening movements of the affected mão in their brains, and the generation of actual movements assisted by exoesqueleto robôs achieves a high degree of matching between motor intentions and behavioral movements, which is more conducive to Remodeling of the cerebral cortex.

At present, the interface cérebro-computador mão função reabilitação robô has gradually been recognized by pacientes.

The picture below shows the paciente's motor imagination task of mão grasping and opening according to the display screen and voice prompts. Each action has 3 imagination opportunities. While the paciente is performing motor imagery, the EEG dispositivo pode collect the characteristic EEG signals of the cerebral motor cortex through the collector.

If the paciente pode accurately complete the motor imagery task within 3 times, the EEG signal will complete the signal extraction and feature conversion through the signal converter, and then control the exoesqueleto manipulator to ajudar the paciente complete the corresponding grasping or opening action; If the motor image cannot be accurately completed within 3 chances, the EEG signal converter cannot be triggered to complete the movimento of the exoesqueleto manipulator. According to the paciente's performance, the system will score the paciente's degree of completion, which also improves the paciente's enthusiasm for participating in the training.

 However, at present, there are still some problems with mão função reabilitação robôs commonly usado in clinical practice. It is hoped that such problems pode be melhorado in future research.
