I'm sorry to read that...
It is a nothing pleasant condition, not only for the people who live it in their own flesh, but also for the people of the environment. My father-in-law, lived his last years in a wheelchair and finally in a bed. That was sad to see the transition and deterioration of their health. But we cheer, that with love and care everything works better. I wish your mother great health and for you too. Devices that improve the quality of life, are really welcome and appreciated...!
Regards..
