Thank you so much for your reply....when I say an appliance, I mean a support that I could wear under trousers that would give me something to "push against" when getting up. I am able to get up and down OK with something to lean on and I was just off on a mental tangent trying to think of anything that might help. Yes you are correct in thinking I need to get up and down independently. I will get a referral back to my orthopod and see what he has to say.
Thank you so much again for your reply....although there is no solution therein, it does light my path somewhat as to where to go/what to do.
Have a good day
