Abstract
As an example, a walker includes a first leg pair, a second leg pair and a cross beam connecting the first and second leg pairs in a parallel, spaced apart relationship. Each leg pair includes a U-shaped tube defining a front leg and a rear leg. A front strut is telescopically movable within the front leg and extends outwardly therefrom. A rear strut is telescopically movable within the rear leg and extends outwardly therefrom. A mechanical linear actuator includes a rotating element adapted to rotate relative to at least one of the front leg or the rear leg. The rotating element includes an interface with a track on the respective strut relative to which the rotating element rotates, whereby rotational motion of the rotating element translates to corresponding linear motion of the strut.
