Peters说：
Peters said the major complication was leg weakness that developed among eight of the nine with spina bifida. All had been able to walk before the surgery. They often required intense physical therapy, Peters said, “just to get them back to baseline.” One child developed drop foot, meaning he could not raise his foot when he walked.
Peters还说：
A risk of lower extremity weakness is evident in that 1/9 subjects had a permanent foot-drop
专家评论说：
Persistent foot drop cannot be considered a minor complication in children who are already motor disabled.

1/9对应中国2000名患者中超过100名足下垂
中国患者没有机会接受intense physical therapy
