Ankles are tricky joints, i know what your all going through i wish everyone a speedy recovery, and as hard as it is rest ice and elevation is the best thing for it.

ode i had to go through that whole learn to walk procedure, it is not an easy task, your body adapts to moving around to compensate, and it is hard work to retrain your limbs to move correctly, i shattered my knee (not quite an ankle) but for nine months i couldnt walk without the assistance of crutches after the couple of surgeries to rebuild it it was almost another 9 months to get it back to some sort of normal movement.

With your support i am sure your mum will make a great recovery!!
