ABSTRACT:
A device for manipulative therapy has a base and two support plates carried above the base by a plurality of links pivoted to the base and the respective plates. The links are disposed at angles such that the plates are movable in arcuate paths away from each other and towards the base. A control, mounted on the base beneath each plate has a spring biased spool engaging the respective plate. The spool has a groove engaged by a detent when the respective plate is in its uppermost position, requiring a predetermined force to be applied to the upper surface of the plate to produce downward, arcuate movement of that plate.
