Lancet:硬膜外电刺激助力截瘫患者重新站起

2013-07-27 Harkema MedSci原创

  2011年5月20日,美国路易斯维尔大学脊髓研究中心报告了1例完全丧失运动功能的截瘫患者,通过硬脊膜外电刺激配合康复训练,恢复了部分站立和行走功能。论文在线发表于《柳叶刀》(Lancet)杂志。   该患者为1例23岁男性患者,3年前因外伤导致C7~T1半脱位,完全丧失随意运动功能,仅保留T1截面以下部分感觉功能。在进行了170个疗程(持续超过26个月)运动训练而无康复迹象后,研究者于患者腰

  2011年5月20日,美国路易斯维尔大学脊髓研究中心报告了1例完全丧失运动功能的截瘫患者,通过硬脊膜外电刺激配合康复训练,恢复了部分站立和行走功能。论文在线发表于《柳叶刀》(Lancet)杂志。

  该患者为1例23岁男性患者,3年前因外伤导致C7~T1半脱位,完全丧失随意运动功能,仅保留T1截面以下部分感觉功能。在进行了170个疗程(持续超过26个月)运动训练而无康复迹象后,研究者于患者腰骶部(L1~S1)硬脊膜置入一组16个电极阵列,以提供慢性电刺激,并进行了29次相关实验,以找到适宜的站立及行走的刺激参数。

  治疗数周后,在硬膜外电刺激下,患者可实现完全承重站立。在置入电极7个月后,患者在存在硬膜外刺激时,可进行部分腿部运动。

  A 人类因SCI所致的瘫痪很少为完全瘫痪,多数会遗留备用“组织桥”(无功能下行纤维),以支持功能康复。

  B EES可促进特定任务感觉信息处理,从而产生运动。康复训练可增强无功能下行纤维的可塑性,在EES将脊髓回路调谐后,可促进脊髓上控制功能恢复。
