“意念驱动”助脑卒中患者康复

Core Insights - The article discusses the advancements in a brain-computer interface (BCI) system developed by a research institute in Bengbu, which allows stroke patients to control devices through imagined hand movements, aiding in neuroplasticity and rehabilitation [1][2]. Group 1: Technology and Development - The BCI system translates brain signals generated by imagined movements into control commands for rehabilitation devices, enabling stroke patients to engage in various hand movements [1]. - The system integrates a self-developed scalp EEG collection system, capable of real-time decoding of patients' movement intentions and converting them into control instructions for rehabilitation devices [1]. Group 2: Clinical Trials and Results - A clinical trial involving 8 stroke patients was conducted, showing significant progress with an average improvement of 19% in motor function scores after nearly 200 training sessions over two months [2]. - One patient with left-sided hemiplegia exhibited notable perceptual feedback and muscle reflexes after just one week of BCI-enhanced training, with improvements in Fugl-Meyer scores and Barthel index [2].
