Elevator buttons

Trying to push them when no one else is around. I have to get within one foot of the button, I can rotate my left hand outward that much and as long as the button is around waist height I can get one of my knuckles to push the button, assuming that the buttons aren't in too much of a depression.  The sixth floor button is too high to successfully get most of the time. This is a slow process, but then everything in stroke rehab is slow.
