Application of 手部康复 设备 in 偏瘫的 手部康复 - 卒中 中心 - 司羿 智能的

Statistics show that after 卒中, only 15% of 患者 can recover about half of their 手 功能, and only 3% of 患者 can recover more than 70% of their original 手 功能. It has become a major trend in the 康复 field to explore effective 康复 治疗 methods and promote the 恢复 of 患者' 手 功能. Therefore, the combination of task-oriented training and emerging 康复 technology has gradually become an indispensable 康复 治疗 technology for 手 功能 康复. The emergence of 手 功能 康复 robots has brought new ideas for the 康复 of 手 功能 after 卒中.

This article will briefly share the 智能的 soft 手 康复 机器人 and 脑机接口 手-功能 机器人.

智能的 soft 手部康复 机器人

The 智能的 soft 手 功能 康复 机器人 combines robotic technology and neuroscience, and can provide various training modes such as passive, assistance, resistance, bilateral mirror and active games. It is a 手 功能 康复 机器人 that fully covers the period from soft 瘫痪 to 康复. In the process of 机器人-assisted training, bilateral mirror 治疗 and 运动 imagery were combined to realize the integrated 治疗 of central intervention and peripheral intervention.

With the 智能的 soft 手部康复 机器人, 患者 can stimulate the 运动 cortex of the brain through multi-modal stimulation through visual, auditory and tactile 感觉的 stimulation to 形成 a closed-loop 康复 training and improve the 患者's willingness to actively participate in 手 功能 康复 training to promote the 恢复 of the 患者's 运动 功能. At the 相同的 time, in bilateral mirror 治疗, the healthy 手 drives the affected 手 to exercise, which can further improve the neuroplasticity of the brain.

脑机接口 手-功能 机器人

The addition of new methods makes the closed-loop 康复 model of central-peripheral-central a clinically 重要的 康复 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 感觉的 and 运动 control modes to the brain 中心. The combination of the two modes promotes the remodeling of brain 功能 in 卒中 患者. The 脑机接口 has become the best choice to realize the closed-loop 康复 mode.

脑机接口 training will give 患者 VR visual and auditory dual stimulation, so that they can perform 运动 imagination of the affected 手 movements, so as to control the 外骨格 康复 机器人 to complete the 手 grasping and opening movements. Through 脑机接口 training, 患者 repeatedly imagine the grasping and opening movements of the affected 手 in their brains, and the generation of actual movements assisted by 外骨格 robots achieves a high degree of matching between 运动 intentions and behavioral movements, which is more conducive to Remodeling of the cerebral cortex.

At present, the 脑机接口 手 功能 康复 机器人 has gradually been recognized by 患者.

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

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

 However, at present, there are still some problems with 手 功能 康复 robots commonly used in 临床的 practice. It is hoped that such problems can be improved in future research.
