I take my folks shopping quite often and use the sign all the time. As for the post about elderly people who are walking fine and don't really need it, my mom has a sign and we use it all the time, to see her walk most of the time she looks fine but if she needs to walk extended long distances, her heart starts to be affected because of a heart condition she's had since childhood. Also her arthritis will cripple her within a couple hours of doing such walking. It's a preventative measure quite often used for a good amount of people.
