I suppose it really depends on how your body works

 Crutches can somewhat be a trick of the mind, your brain wants to move a certain way and crutches simply

won't let you do that. But with something like knee walkers you can get around very easily and it can definitely bring a new sense of mobility into your life. For home use you could consider using

a commode chair as well.
These are nifty little chairs with casters or wheels on the bottom of the chair, somewhat compared to a walker. Instead of just walking with these though, you can actually walk to the toilet and

hover over the toilet while sitting in the chair - it goes right over the toilet. This is also a nice option for people that have bad knees and simply cannot bend down the way they used to be able

to. So when it comes to not only walkers, but all of these products they are bound to promote more usability, functionality and overall comfort.
For the most part it seems that there are two types of people - those that can use and do use manual wheelchairs or motorized wheelchairs, and those that can use and do use rolling walkers or other

types of walkers. I suppose it really depends on how your body works. With rolling walkers, you don't need as much leg strength as one would think, but you do need to have a lot of upper body

strength. These rolling walkers are a great new addition to the old walkers where you had to actually inch forward.
These rolling ones will instead "glide" or roll across the floor thanks to coasters or little wheels on the bottom of the walkers. This is definitely about ease and convenience. My grandfather used

to use a regular walker and it took him a good 2 minutes for every single step the man took. How pitiful! I always felt so bad for him. Last Christmas though, I decided to surprise him with one of

these rolling walkers and now he zooms around the house as if he didn't even have a walker at all. It's a major confidence booster for the person as well because now they no longer feel like a

bother.
Now he can do stuff on his own, and we don't have to watch him every single second to make sure he's alright. Also, there are rolling walker with seat options as well. These are the same as a

rolling walker in that they do roll, but the seat option allows the user to sit down, pretty much whenever the user wants to. I've seen these in action and to be honest it sort of pulls at my heart

strings because before with a regular walker the user simply had NO other choice.
