摘要 目的 研究遗传性痉挛性截瘫 4型 (SPG4 )的临床、电生理和MRI特点。方法 对来自 4个家系的 13例SPG4患者的临床、电生理及MRI资料进行分析。结果  13例患者中单纯型 4例 ,复杂型 9例。 2 0岁以前发病者 7例。所有患者均以缓慢进展的双下肢僵硬、行走困难起病 ,表现为双下肢痉挛无力 ,可合并智力下降 (3例 )、锥体外系症状 (2例 )、共济失调 (4例 )、肌肉萎缩 (1例 )、深、浅感觉减退 (4例和 2例 )和弓形足 (3例 )。各家系患者功能评分差异较大。肌电图、体感诱发电位检查各 3例和头颅MRI检查 2例均未见异常 ,胸髓MRI检查 2例均显示胸髓萎缩。结论 spastin基因突变既可导致单纯型SPG患者 ,也可导致复杂型SPG患者 ;
