Walking With Crutches

My mother finds it difficult to walk up and down stairs with crutches when leaving the house, therefor she has to try to balance the crutches against a secure surface and walk up the stairs. However, the crutches tends to fall over constantly. As she has a lack of balance she finds it difficult to bend down to pick them back up. This problem also occurs in other public places such as supermarkets, travelling to the car ect. As she uses two crutches as a walking aid, it is very difficult trying to balance both.
