Abstract: An ambulatory assistance device includes a base having a set of wheels the base configured to at least partially surround a patient's body to provide a maximum level of support along all possible force vectors. The base includes ballast to lower the center of gravity of the ambulatory assistance device. Furthermore, the ambulatory assistance device includes a frame assembly having a handle extending from the base. The handle is disposed at a distance between about two inches and three inches proximal to the center of gravity of the unit. This positioning of the handle, in combination with the positioning of the wheels of the base provides the ambulatory assistance device with a substantially stable design.
