Advice for 79 year old mom

Thank you to everyone in this community who have been so helpful to me with my amputations. Question about my 79 year old mom. Not getting am amputation but just blew our her knee. Any advice on aids and accessibility devices you can share with me especially geared for a head strong Italian senior mom is appreciated. I advise her on what works for me, but at fifty and in shape it's a bit different.

She is doing OT, so this would just be a supplement and help me talk with them.

I suggested a narrow gauge indoor wheelchair or rollator. They have a stair lift already. So.in addition to that and grabbers,

Thank you in advance.
