Mature:植入大脑芯片能够帮助四肢瘫痪的人恢复手部运动能力

一场反常的潜水事故,让19岁的 Ian Burkhart 陷入了胳膊和腿瘫痪的灾难之中。目前研究人员表示,这名已经24岁的前运动员,通过一项实验已经恢复了其手指、手、手腕的一些活动能力。

研究人员表示,通过外科手术讲一个承载信息的电脑芯片植入 Burkhart 的大脑,绕过受伤的脊髓,直接控制四肢的活动性。

“在本项研究中,电子神经搭桥技术发挥了重要的作用,它向人们展示了这一应用最光明的未来,也许在不久的将来,能够通过该技术帮助世界范围内的数以百万计的瘫痪人群重新恢复运动能力,”该研究的作者 Gaurav Sharma 研究员表示,他任职于俄亥俄州哥伦布巴特尔纪念研究所。

Burkhart 在高中时期,是一名俄亥俄州都柏林地区的曲棍球守门员,他在北卡罗来纳州外滩享受海洋度假的过程中受伤。研究人员表示,目前,在全球范围内,有数以百万计的人们被瘫痪症困扰,该研究通过一项电子神经搭桥技术帮助 Burkhart 重获运动能力,这是瘫痪治疗的革命性的进步。

电子神经搭桥技术是如何发挥作用的?医生于2014年向 Burkhart 的大脑运动皮层植入了电脑芯片,这一芯片主要负责控制手部运动,Sharma 表示。

“通过记录运动皮层的传输信号,在将信号传输给计算机,帮助研究者们了解了瘫痪肌肉的信号传导方式,我们通过芯片绕过这些受损的脊髓组织,稳定地向目的组织传送运动命令信号,”他表示。

目前,Burkhart 已经能够基本恢复手指、手部、手腕的低强度运动能力,他还能够完成握拳以及释放等指令,Sharma 表示。

该研究相关文章发表于4月13日的《自然》(Nature)杂志上。

政协委员诊断被打女护士为瘫痪 呼吁立法保护

全国政协开幕会结束。温建民委员,一名骨科医生,被问起最近闻名全国的南京医院暴力事件。 视频监控记录的打人现场 “我们要帮这个小孩!”温建民说的是受伤的护士陈星羽,“我们去了南京,到病房看过她,她很坚强,没有抱怨。我和凌峰委员带去了两万元救助金。另外还给她做了诊断:就是瘫痪,0到1级的肌力,站不起来嘛。” 事件回顾:南京口腔医院护士被打 南京警方先前曾告诉媒体,他们跟打人

新技术:脑电波控制系统让瘫痪患者走起来了!

一项新的研究表明,一个26岁男子在双腿瘫痪五年后,利用用脑电波控制系统和能支持他体重背带系统,他成功迈出了步子。这项研究发表在本月23日的《Journal of NeuroEngineering and Rehabilitation》上。为了重获走路的能力,病人头顶戴着特殊的帽子,帽子上布满电极可以检测到他的脑部电波信号,然后转化为电信号。这些电信号与脑电图测试时的信号类似。这些电信号被送到

Spine J:瘫痪患者行手术,有助于驾车安全

背景:已有多项研究报道了数种手术对患者术后驾驶反应时间(DRT/driving reaction time)的影响。然而作为脊柱疾病中最常见的一种:腰椎间盘突出症,其手术对驾驶反应时间的影响却从未被报道过。 目的:分析腰椎间盘突出症引起的左侧或右侧瘫痪患者术前及术后驾驶反应时间的差距。 方法:本实验为前瞻性临床对照试验,纳入者均为即将进行腰椎间盘手术的患者。本实验所考察的指

功能性电刺激促进瘫痪患者肌肉收缩

  脊髓损伤患者的大脑和脊髓回路的连接中断,无法进行随意运动。美国西北大学芬伯格医学院的C. Ethier等研究证明:利用功能性电刺激(functional electrical stimulation,FES)达到肌肉收缩的临床系统,可让四肢麻痹的患者恢复对手臂运动的控制并极大改善其日常行为的自理能力。   研究者向恒河猴肘部注射局麻药阻断正中神经和尺神经,来模拟颈椎C5、C6段脊髓损伤导致的

4 万美金的外骨骼,让瘫痪病人重新站起来

在一次越野骑行中,Sanchez 意外地失去了双腿,随后他被送到了位于加州伯克利市的 SiutX 公司,一个半小时后他又重新站了起来。实际上 SiutX 公司利用“凤凰”机械骨骼让他可以像正常人一样自由行走。 提到机械外骨骼,大家想到的一般都是电影里面十分夸张、机械感极高的装备,不过之前爱范儿也报道过可以在家自己做外骨骼外挂装备用于农事。外骨骼除了可以赋予你大力气之外,还能够让瘫痪的人重新站起来

Science:光遗传技术助瘫痪肌肉恢复功能

利用闪光刺激经过遗传修改的神经元,可以恢复瘫痪肌肉的运动功能。英国科学家在小鼠身上开展的这项最新研究,为使用光遗传学技术来治疗脊髓损伤、癫痫以及运动神经元疾病等神经失调疾病铺平了道路。 光遗传学是神经科学领域近来发展最快的技术之一,它涉及到对神经元进行遗传修饰,使其产生一种光敏蛋白,当暴露在光照中时就会发送电信号。到目前为止,光遗传学技术主要被用于研究大脑如何工作。有些团队也在探索将其作为一种治
