我国介入式脑机接口成功实现人体患肢运动功能修复

Core Viewpoint - The successful clinical trial of an interventional brain-computer interface (BCI) in China has demonstrated its potential to restore motor function in a patient with hemiplegia, marking a significant advancement in the treatment of movement disorders [1][4]. Group 1: Clinical Trial Details - The clinical trial was led by Professor Duan Feng's team from Nankai University, in collaboration with experts from Fujian Sanbo Brain Hospital and Fujian Second People's Hospital [1]. - The subject of the trial was a 67-year-old male patient who suffered from left limb paralysis due to a cerebral infarction for six months, with traditional treatment options offering little hope for recovery [1][3]. - The interventional BCI was implanted through a minimally invasive procedure using high-precision DSA imaging guidance, allowing for the placement of a stent electrode in the patient's intracranial blood vessel wall [1][3]. Group 2: Technological Advancements - The trial combined interventional BCI technology with functional electrical stimulation, creating a "central-peripheral-central" closed-loop feedback system that enhances neural plasticity while assisting in motor training [3]. - The patient has achieved significant improvements in motor function, including the ability to perform daily tasks such as grasping and taking medication with the left upper limb [3][5]. Group 3: Implications and Future Prospects - The success of this trial validates the safety and effectiveness of interventional BCI technology for clinical applications, paving the way for future large-scale applications [4]. - This technology represents a forward-looking, disruptive, and strategic emerging industry, offering new treatment options and rehabilitation hopes for patients with movement disorders such as stroke, paralysis, and amyotrophic lateral sclerosis [4].
