Did you get doctor clearance and advice? Does she have physical rehabilitation information for you?
You can do almost any move for those areas, except, do not expect her to be able to have perfect form as a client without hyper lordosis. Also, avoid letting her lift both legs at the same time, and be happy with smaller range of motion.
Please, pay close attention to the client, and start off slowly with easy and gentle moves.
Good luck to you both.
