Abstract
A mobility assisting device which includes a vertical support structure pivotally coupled to a substantially planar base structure. The vertical support structure can have an underarm support so that the base remains parallel to the ground as the base moves relative to the ground. The underarm support is mounted to the vertical support structure so as to be pivotal relative thereto to avoid the translation of pressure points under the patient's arms and rubbing between the upper end of the support and the underarm. The underarm support is angled relative to the plane of the device increase the comfort to the user. The base is biased perpendicular to the support structure by a resilient shock dampening pad between the support structure and the base.
