When standing on patient’s right use left hand for palpating hand and right hand for contact with the vertebra, using left hand again to grip and reinforce the contact hand. Exception to this is made by introducing an extra change of hands with C 6, or 7, D 1, L 4 or 5, and Sacrum. The change is necessitated by the insecurity of the usual position or the fact that it cramps the wrist of contact hand. To make the change: palpate as usual, hold subluxation with second finger of palpating hand, substitute second finger of other hand and withdraw palpating hand, which is then free to make the contact.
When standing on left side exactly reverse the use of hands. Palpate with the same hand which would be used if patient were sitting. Introduce no unnecessary move into the placing of the hands. This will be found to produce better results than any other technic for this portion of the move.
Delivery of Force
In using this movement it is perhaps best to deliver nearly equal force with both hands; certainly whatever forces are released by the arms should be simultaneous. It is possible, however, to allow one arm to preponderate in the movement without marring its efficiency, but the amateur adjuster will do well to balance his forces at first.
Speed and Concentration
Speed is a prime essential. By its employment a very ordinary amount of muscular strength can be made to accomplish a large amount of work and very difficult adjustments may be accomplished.
Concentration of mind at the instant of adjustment, so as to secure muscular control and perfect co-ordination of the two arms as well as to direct and concentrate the forces used at a given and strictly limited area, is also essential.
Uses
For ordinary adjustments of Dorsal or Lumbar subluxations, excepting the middle four Dorsals, for breaking ankyloses by repeated applications of force, and for overcoming muscular resistance in patients who are unable to relax at all, this form or style of adjusting is probably the best. It is most useful in the Dorsals. In many instances Lumbar vertebrae will move better by application of a slightly slower force, especially if a roll is used. The Recoil may be used with the roll.
