Application of hand إعادة التأهيل device in hemiplegic hand إعادة التأهيل - السكتة الدماغية Center

Statistics show that after السكتة الدماغية, only 15% of patients can recover about half of their hand function, and only 3% of patients can recover more than 70% of their original hand function. It has become a major trend in the إعادة التأهيل field to explore effective إعادة التأهيل treatment methods and promote the recovery of patients' hand function. Therefore, the combination of task-oriented training and emerging إعادة التأهيل technology has gradually become an indispensable إعادة التأهيل treatment technology for hand function إعادة التأهيل. The emergence of hand function إعادة التأهيل robots has brought new ideas for the إعادة التأهيل of hand function after السكتة الدماغية.

This article will briefly share the intelligent soft hand إعادة التأهيل robot and واجهة الدماغ والحاسوب hand-function robot.

Intelligent soft hand روبوت إعادة التأهيل

The intelligent soft hand function روبوت إعادة التأهيل combines robotic technology and neuroscience, and can provide various training modes such as passive, assistance, resistance, bilateral mirror and active games. It is a hand function روبوت إعادة التأهيل that fully covers the period from soft paralysis to إعادة التأهيل. In the process of robot-assisted training, bilateral العلاج بالمرآة and motor imagery were combined to realize the integrated treatment of central intervention and peripheral intervention.

With the intelligent soft hand روبوت إعادة التأهيل, patients can stimulate the motor cortex of the brain through multi-modal stimulation through visual, auditory and tactile sensory stimulation to form a closed-loop إعادة التأهيل training and improve the patient's willingness to actively participate in hand function إعادة التأهيل training to promote the recovery of the patient's motor function. At the same time, in bilateral العلاج بالمرآة, the healthy hand drives the affected hand to exercise, which can further improve the neuroplasticity of the brain.

The addition of new methods makes the closed-loop إعادة التأهيل model of central-peripheral-central a clinically important إعادة التأهيل theory. Central intervention can promote the activation of the corresponding functional brain areas of the brain and improve 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 function in السكتة الدماغية patients. The واجهة الدماغ والحاسوب has become the best choice to realize the closed-loop إعادة التأهيل mode.

واجهة الدماغ والحاسوب training will give patients VR visual and auditory dual stimulation, so that they can perform motor imagination of the affected hand movements, so as to control the الهيكل الخارجي روبوت إعادة التأهيل to complete the hand grasping and opening movements. Through واجهة الدماغ والحاسوب training, patients repeatedly imagine the grasping and opening movements of the affected hand in their brains, and the generation of actual movements assisted by الهيكل الخارجي robots 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 واجهة الدماغ والحاسوب hand function روبوت إعادة التأهيل has gradually been recognized by patients.

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

If the patient can 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 الهيكل الخارجي manipulator to help the patient 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 movement of the الهيكل الخارجي manipulator. According to the patient's performance, the system will score the patient's degree of completion, which also improves the patient's enthusiasm for participating in the training.

 However, at present, there are still some problems with hand function إعادة التأهيل robots commonly used in clinical practice. It is hoped that such problems can be improved in future research.
