I'm taking care of a elderly relative that tends to lean back and fall down. She has fallen backwards while holding onto her walker with the walker ending up on top of her. The problem is a issue of technique. She tends to use the walker standing inside it instead of behind it and leaning forward a little bit. I, and PTs, have tried to teach her otherwise but it doesn't take. A posterior, reverse, walker seems to be more supportive of this use. It also seems to be more sturdy in preventing backward falls. I know they are popular for kids but not much is said about them for adults let alone the elderly where anterior walkers seem to be the norm. Is there a reason posterior walkers are used for the elderly? Is it a bad idea? If not, any reason not to try it?
