Text Appearing Before Image:
st spinous, fingers rigid and flexed on hand,last finger firmly anchored, or pressed into the flesh, toprevent slipping. (Fig. 22 shows the position.) The anchoring fingers must always extend away from theadjuster. To turn the fingers back across the spine, in mov-ing a vertebra toward you, is always an error, and the priceis partial loss of use of one arm. With the adjusting hand satisfactorily placed, grasp itswrist firmly with the other hand so that the pisiform of thesupporting hand rests in the hollow between the wrist andthe metacarpal bone of the extended thumb. By this con-tact force is driven directly through the chain of bonesacross the wrist and to the pisiform bone without spreading.In grasping the wrist let the thumb extend around the fore-arm in one direction and the four fingers in the other. Be-ware of gripping only with thumb and first finger in whichcase the edge of the supporting hand will rest on the backof the contact hand and spread the delivered force toowidely.

Ci^ Technic of Adjusting 129 Movement I have said, but have not sufficiently emphasized thecommand, that the shoulders must be dropped loosely for-ward. Let me add that just before the movement is giventhe head should be allowed to sag downward and the mus-cles to become relaxed. This movement given with stiffshoulders and upraised head becomes a push. The desired movement is a throwing movement. Force is released from both shoulders at once, concen-trated at the same instant by a slight shifting forward ofthe elbows, and strikes the spinous process as one force,which is the resultant of the two meeting at the wrist ofcontact hand and being united there. The two arms use thecontact hand as a passive instrument for driving the ver-tebra. The objective point, the distance to which the movementis mentally thrown at the instant of delivery, should be thecenter of mass of the vertebra, varying according to thesection of the spine. Contact Point The exact contact point of hand with vertebra
