This cane is collapsible and thus easier to transport. These canes have four legs, which means better stability and contact with the ground. With four legs, it can also stand on its own, which is helpful because you don't have to hold it all the time. The extra legs also increase the weight of the cane and the coordination necessary for moving it. The difference between canes and crutches is the point of weight bearing.
Crutches allow some of the weight to be borne by the shoulders and the wrists.
This platform crutch uses a padded support to allow your elbows and forearms to bear weight. This forearm crutch has a handle to grab for supporting weight and a cuff for increased forearm stability. This walker is a standard model. Rubber tips on the feet mean you get better traction but would need to pick it up to move. Small rubber grips on the handle make it easy to hold and push, but don't give any additional support.
