Quad Cane

This device also can stand upright without support, has a larger base of support than the standard cane, and it allows for more weight to be put through the arm/hand.

Rollator

This device allows the fastest walking speed.
It has a seat for resting breaks, a basket for carrying items, and has breaks on handles.
This is the least stable full walker since it has wheels on all four legs. And it does not allow for very much weight to be pushed through the hands/arms.

The rollator is ONLY for patients who:
👉Need an immediate place for sitting break
👉Have good balance without needing to lean his/her weight onto the walker.

Rolling Walker

This allows for a faster walking speed for the user and easier to move.
There are tennis balls or glides on the back legs for easier sliding.
This assistive device does not need to pick up the back legs when walking since it just slides.
The downfall of this device is that the wheels can roll out from under the patient if all four legs are not in contact with the ground/floor.
