回复：她偶尔说一句，很短，大部分功能还没有恢复

From what you said her case is rather serious. Also taken into account her age, she may not regain her mobility. But you also said she pulled out her feeding tube, that means she can use her hand, which is not bad.
Elderly people who had stroke feel miserable and are like kids in many ways, you can not be more patient to care for them, day in and day out. Again, it is important to get the necessary nutrition and treatment, especially in the early stage after the stroke. Just try everything. If it doesn't work, it couldn't make it much worse.

And try to stay with her as long as you can.
