The present application is directed to a device for transporting users having an injured leg across a surface and a method of adjusting the device. An embodiment of the device includes a frame, at least two wheel assemblies, and a support for supporting the knee of the injured leg of the user. The frame may have a top portion and at least two legs. The wheel assemblies may be operatively connected to the legs of the frame. The support may be at least partially supported by the top portion of the frame. The device may include an anti-rotation arrangement that increases the resistance to the rotation of a wheel of at least one of the wheel assemblies to assist alignment of the device with a forward direction when a force is applied by the non-injured leg of the user in a direction that is parallel to the forward direction. |
