脑机接口等新兴科技对传统外科重建肢体功能的启示

肢体瘫痪是人类致残的最主要原因，仅脑卒中等造成的偏瘫在我国就达两千余万患者，长期“无医可治”。中国原创的左右颈七神经交叉移位，将瘫痪上肢神经换接到同侧健康大脑，不仅偏瘫肢体功能显著恢复，更进一步更新发展了传统脑科学理论。然而对于脊髓损伤后肢体瘫痪或严重肢体残缺患者来说仅依靠医学方法尚不能有效治疗。近年来，围绕传统脑电技术发展而来的脑机接口等新兴技术衍生出的交叉学科逐渐兴起，拥有能够解决医学遗留难题的潜能，在国内外掀起一番热潮。作为国家战略需求，研究者应当抓住机会，加大力度支持跨领域、多学科融合，共同研发肢体功能重建新方案，实现新兴科技与中国原创技术融合的再次突破。

The inspiration of emerging technologies such as brain-computer interface on conventional surgical treatment for limb function reconstruction

Limb paralysis is the main cause of human disability. Hemiplegia caused by stroke alone has affected more than 20 million patients in China, and there is currently no cure for this disease. We created the original contralateral C7 to C7 cross nerve transfer surgery that swapped the link of the brachial nerve of the paralyzed side to the ipsilateral healthy brain. Not only did hemiplegic limb function recover significantly, it also broke the traditional neuroscience theory. However, for patients with limb paralysis or severe limb disability after spinal cord injury, the practicality of traditional medical methods is still facing the doubt of effectiveness. In recent years, interdisciplinary cooperation derived from emerging technologies such as brain-computer interfaces based on the development of traditional EEG technology have gradually risen. They have the potential to solve the problems left over from traditional medicine and have taken a great upsurge at home and abroad. As a national strategic demand, we should seize this opportunity to increase our efforts to support cross-field and multi-disciplinary integration to jointly develop new solutions for limb function reconstruction, and achieve another breakthrough in the integration of emerging technologies and Chinese original technologies.
