定义
在SMA 1型中,虚弱的发生可能在产前(妊娠末期胎动减少)或在出生后的前6个月内。婴儿表现出典型的蛙式姿势,大腿外旋外展,膝盖弯曲(婴儿软弱无力)。延髓无力导致喂养困难。儿童在没有支撑的情况下永远不能坐起来,平均生存期为9个月;存活期超过2年的情况很少。
In SMA type 1, onset of weakness may be prenatal (decreased fetal movements toward the end of pregnancy) or within the first six months of life. Infants demonstrate a characteristic frog position with the thighs externally rotated and abducted and the knees flexed (floppy infant). Bulbar weakness causes feeding difficulty. Children are never able to sit without support, and the average survival is 9 months; survival beyond 2 years is rare.
