For rotated first or second Dorsals with which, for any reason, the “T. M.” fails. This move involves a use of the head as a lever, as does the “T. M.” No. 2. Inadvisable unless the posterior transverse of the rotated vertebra can be palpated--but often used in cheerful disregard of this detail by those sublimely capable adjusters who do not need to find a vertebra before moving it. Palpation--Contact Palpate as for No. 1 above. Very deep palpation will be necessary because the spinous process here is nearly horizontal to the body and the transverse is very deeply placed, overlaid with heavy muscles. When process is found place pisiform bone of free hand upon it, pressing the muscles aside as much as possible to avoid bruising and resting a considerable amount of weight upon the contact hand. Fingers of contact hand may extend across the spine or downward and parallel with the spine. Or, the hands may be changed so that the palpating hand becomes the contact hand and is placed with the fingers gripped over the base of the neck toward the clavicle. Head Leverage The free hand is now placed upon the forehead and the head, which faces toward the contact hand, is flexed backward until the muscles seem taut. Movement Is a quick, but fairly gentle, movement of both hands together, so that the head is rocked still further backward at the instant an anteriorly directed force is applied to the prominent transverse. The result is rotation of the vertebra--unless there be a loose articulation in the Cervicals which gives way under the force applied to the head. THE EDGE CONTACT (“Point 2 Contact”--“Knife Move.”) Name This movement has various names. The name “Point 2 Contact” is handed down from the days when Palmer used three contact points and three moves and designated the middle of the ulnar side of the fifth metacarpal bone as “Point 2.” The name “Edge Contact” was applied later, during the improvements in its technic when the hooking of the thumbs stiffened its efficiency and made it very valuable. It has since been rediscovered (though in constant use) and re-named “Knife Move.” Uses A movement which uses the spinous process as a lever and is applicable to D 2, 3, or 4, and to any Dorsal or Lumbar from D 8 down, when posterior, postero-superior, or postero-inferior. It does not correct rotation except insofar as the shape of articular processes may aid an anteriorly directed move in rotating the vertebra. Some Chiropractors have used the Edge Contact in the Cervicals but this is always improper, as it is practically impossible in some, and difficult in all, cases to cover only one spinous process when the head is resting on its side.
