A mobility assistance apparatus having an elongated frame. The elongated frame includes a pair of disparate sized wheels coupled to each end of an elongated frame. A pivoting joint is provided longitudinally in the elongated frame which allows the second wheel to track the first wheel in a lateral arc about the along a longitudinal centerline of the first wheel.

What is claimed: 1. A mobility assistance apparatus comprising:an elongated frame including;a first frame element having a front wheel coupled thereto, the front wheel having a fixed rotational axis along a longitudinal centerline of the first frame element;a second frame element having a second wheel coupled thereto, the second wheel having a fixed rotational axis along a longitudinal centerline of the second frame member;a pivoting joint which couples the first frame element with the second frame element; the pivoting joint configured to allow the second wheel to track the first front wheel in a lateral arc;a handle assembly coupled to the elongated frame at an angle; the handle assembly configured for allowing a user to apply a generally downward or tangential force relative to the elongated frame such that the mobility assistance apparatus moves in cooperation with movement of the user; and,wherein the pivoting joint comprises a longitudinally tapered forward end dimensioned to fit within an end of the first frame element in such a way that lateral movement of the tapered forward end within the first frame element limits the lateral arc of the second frame element.
