Apparatus and method for continuous passive motion back support for a person comprising a fluid-inflatable bag disposed between a static structure and the back of a person, the fluid-inflatable bag including a back-engaging surface cyclically moveable to increase and decrease the distance between the static structure and the back-engaging surface thereby to cycle the lower back through a substantial range of lordosis, a conduit adapted to conduct the fluid between the reservoir or the atmosphere and the fluid-inflatable bag, and programmable circuitry for adjusting a voltage supplied to an electrically-powered pump, whereby fluid flow in the conduit is effected by adjustably operating the electrically-powered pump. Various multiple bag embodiments are disclosed. Also disclosed is an apparatus and method for providing a baseline support pressure during continuous passive motion for the lower back of a person.
