Abstract: A mobility assisting device which includes a vertical support structure and a substantially planar base structure mounted to the vertical support structure so as to be articulatable relative thereto. Thus, the base remains parallel to the ground as the user rests upon the device and moves relative to the ground. Such a structure maximizes the stability of the device and minimizes the likelihood of slippage due to uneven, moist, icy or otherwise torturous terrain. The patient supporting structure is mounted to the vertical support structure so as to be pivotal relative thereto so as to avoid the translation of pressure points under the patient's arms and rubbing between the upper end of the crutch and the underarm. Further, the vertical support structure and the base structure are preferably spring mounted to one another so as to be urged into perpendicular relation.
