Movement limiting system for a walker that limits movement of the walker includes an elongate, adjustable length armature having first and second opposite end regions and a coupler that couples the first end region of the armature to the walker. When the second end region of the armature is coupled to an object, the walker is limited in its movement relative to the object by the armature. The second end region of the armature includes attachment structure that couples the armature to the object. The armature preferably includes multiple sections that telescope relative to one another to provide the armature with its adjustable length.
