放轻松，这种脑机接口不用脑袋“开口”了

Core Insights - The article discusses a groundbreaking intervention using a brain-machine interface (BMI) to assist patients with motor function recovery after a stroke, allowing them to control their movements through thought alone [1][10]. Group 1: Technology Overview - Brain-machine interfaces connect the brain directly to external devices, bypassing peripheral nerves and muscles, which has been a focus of research for years [2]. - The intervention described is the first of its kind to use an invasive BMI for motor function rehabilitation, developed by a team led by Professor Duan Feng from Nankai University [1][4]. - The invasive BMI is implanted in the blood vessels surrounding the motor cortex, improving signal accuracy compared to non-invasive methods while avoiding the risks associated with traditional invasive procedures [4][5]. Group 2: Clinical Trials and Results - The team conducted successful animal trials before moving to human clinical trials, demonstrating the safety and efficacy of the invasive BMI [5][6]. - The first human trial involved a 67-year-old stroke patient who was able to perform tasks like grasping and manipulating objects with the assistance of the BMI [10]. - The BMI was implanted for several days without complications, and the patient showed improved control over their movements, indicating the potential for significant rehabilitation outcomes [10]. Group 3: Future Implications - The research aims to provide new treatment options for various motor function disorders, including stroke sequelae, spinal cord injuries, Parkinson's disease, and amyotrophic lateral sclerosis (ALS) [10]. - The increasing prevalence of stroke in China highlights the urgent need for innovative rehabilitation technologies like the BMI [10]. - Several hospitals across the country are beginning to establish clinical research units for BMIs, indicating a growing interest and investment in this technology [10].
