THE “SPREAD” MOVE
Upon the theory that when two forces are simultaneously applied, the one to drive some vertebra cephalad (by its spinous process) and the other to drive some lower vertebra caudad, the intervening vertebrae tend, if anterior, to be drawn outward or toward a more posterior position, this move is predicated.
The author does not believe that it accomplishes its purpose, but will briefly describe it for the benefit of those who do.
Position
Patient is placed over a roll which rests under the thighs so as to flex thighs and pelvis on the Lumbar spine, or an adjustable table is so tilted, both sections sloping downward from the middle, as to accomplish the same result.
Contact
The usual method, if only a single vertebra is anterior, is to make contact with the vertebrae immediately adjacent, crossing the hands and having fingers of upper hand pointing toward head and of lower hand toward Sacrum. But some adjusters use this move differently, making contact with Sacrum and with the mid-dorsal region in general and applying a slow force with both hands. Contact is with heel of hand upon spinous process.
