METHOD FOR CHIROPRACTIC ADJUSTMENT Filed Jan. 50, 1953 FIG. I
A TTORNE YS United States Patent Ofiiee 2,727,510 Patented Dec. 20, 1955 2,727,510 METHOD FOR CHHRGPRACTIC ADJUSTFVEENT Joseph Clay Thompson, Davenport, Iowa Application January 30, 1953, Serial No. 334,159 Claims. (Cl. 128-69) My invention relates to an improvement in the healing art as applied by the chiropractic profession in adjusting subluxations of various patients, more particularly in the upper cervical region.
The objects of my invention are:
1. To provide a method or process for adjustment of the occiput, atlas, axis or third cervical vertebra, any or all of them, in a manner which will greatly lessen or avoid the pain a patient is frequently caused to suffer from a vigorous application of force for adjustment of subluxations in that region;
2. To provide such a method of adjustment of increased and superior effectiveness and accuracy for removing subluxations of the cervical region of the spinal column;
3. To provide a method of adjustment which will be useful overadjustment of subluxations or misalignments and the bad effects resulting therefrom;
4. To provide a method of adjustment which will enhance and improve the effect of recoil and reduce or avoid excessive recoil of any of the parts involved, and which will reduce the number of adjustments necessary in most cases;
5. To provide a method for adjustment of spinal subluxations which can under adjusting force applied by definitely stop the movement of the part of the headpiece in contact with the patients head and neck after an adjusted length of travel thereof, with means adapted to The preferred form of my headrest is fully described in my co-pending application for patent, Serial No. 319,639 and is illustrated in the diagrammatic drawings hereto attached in which Figure 1 is a diagrammatic plan View of headrest usable in my method;
Figure 2 shows a side view of Figure 1;
Figure 3 shows an enlarged detail of one form of locking device to hold the top Figure 4 shows an alternate form of mounting the top plate upon the base plate of the headrest.
In Figures 1 and 2 the base plate 1 is shown with the top plate 2 pivotally mounted thereon upon the shaft 8 carried by suitable mountings 9 and 26, with helical one form of springs. mounted upon bolts 12-21. 5 are mounted upon the base plate 1 and top plate 2 to limit the downward movement of the top plate.
A gauge bolt 24 is shown with its upper end united to the top plate 2 and extending downwardly through the base plate 1 with a wing nut 25 threaded thereon by which the distance open position In Figure 4 the top and base plates are shown hinged together at the outer end thereof with helical springs 23 mounted in suitable sockets 21 and 22 formed in the opposing faces of the top and bottom plates of the headrest.
Stop blocks 4 and by the patient, digital palpation, use caligraph, X-rays, useful for that purpose.
The headrest to be utilized the method described, when of the patients head and neck to cause the top plate of the headrest to come into contact with the stops or base thereof, thus making provision whereby various degrees of force may be applied by the doctor in administering an adjustment.
Until the present time all side posture chiropractic tables designed for upper cervical adjusting (referred to as specific chiropractic adjusting), intended for employment of the toggle recoil for the removal of nerve presplates. the springs can be adjusted to increase or lower the resistance to movement of the top plate while the distance between the plates at the inner end may be regulated in order to increase or decrease the distance the head travels in receiving the adjustment.
When the adjustment is being made, as the head or neck descends there will be increased resistance of the springs. When the head and neck have completed their travel, the top plate and base are provided with means to lock them together, thus preventing the top plate from coming up again until released by the operator, thus permitting the operator to complete the toggle and deliver the proper movement before releasing the top plate.
In the exercise of my invention, any one of the common forms of chiropractic tables, when fitted with such a resilient headrest, may be utilized to support the patient thereon either lying upon one side or kneeling with his head and neck resting upon the headrest in horizontal position and with one ear inserted in a longitudinal channel of the headrest provided for that purpose.
In cervical cases I attain the objects stated by preferably positioning the patient with one side of his head and neck resting upon the headrest and one ear in the channel mentioned for that purpose, and with the mastoid-ternporal regions of the patient resting upon the inner or movable end of the head rest on opposite sides of the channel; adjusting the headrest to provide the desired limitation of upward motion produced by the springs and to limit the downward motion of said movable end produced by the adjusting force; applying point one of the nail hand of the operator to the surface of the neck or head of the patient at or near as possible to the upper end of the transverse process of the atlas or axis; giving a quick forcible downward pressure of the nail hand upon the part contacted, including torque if indicated, and with the toggle movement of the hands and arms of the operator all performed in accordance with the standard generally accepted practice of the chiropractic profession and as described in such books as The Subluxation Specific-The Adjustment Specific and other standard works.
In this specification, I use the term nail hand as used in said book to indicate the hand of the operator applied directly to the proper place in the neck of the patient. I use the term point one to indicate the end of the pisiform bone of the nail hand or wrist, and the terms torque and toggle to indicate the motions described in said book which have become standard practice of the chiropractic profession.
In delivering such adjustments, the nail hand is placed in the position indicated and the other hand, which is called the hammer hand is applied to the nail hand and the power of both hands and arms is utilized in delivering the adjustment.
Quoting from the above mentioned book, it is well recognized that introducing invasionary speed to live man and he resists with recoil speed, which speedy resistance adjusts the subluxation. Innate cannot recoil on slow movement induced by shove or push. She recoils only where there is necessity for a rebound. She will recoil on a quick delivery of forces approaching invasion, or following invasion. Adjustment with that extra something with staying-put value is the correction made by Innate on its recoil rebound to a speedy invasionary force. (Page 420.)
Adjusting vertebra (the adjustment with that extra something) is what happened after my hands have left the back; it is that reaction that occurs when the innate recoils in body of patient, which resets vertebrae into normal position. (Page 426.)
An adjustment-adjustment where we deliver a light, quick recoil concussion of force, letting Innate absorb and recoil in retaliation; knowing Innate will adjust to correct normal position where it belongs and will best stay for longest possible time. (Pages 427-428.)
If the Chiropractor will work to secure an Innate adjustment (the adjustment with that extra something),
utilizing his forces merely as a means to an entree to get Innate to make the adjustment, he will find that the subluxation will stay adjusted more permanently than before. (Pages 427 1-28.)
An adjustment is that which Innate will adjust itself to. If it needs a violent jar to, recoil the vertebra into alignment, then Innate will give it. If it needs a light readjustment, Innate will perform it. (Page 430.)
The danger of overadjustment is generally well recognized. In the book mentioned, it is said:
The adjustment for any and all torqued subluxations will be with nail point one upon either transverse process of atlas or axis spinous process. Great emphasis is now being laid to see that it is nail point one, of nail hand, that is used. (Pp. 431-432.)
An adjustment consists of just so much and not any more; but it must be that just so much. If there are no locks to prevent atlas wedge-side-slipping to the right, and no locks to prevent its being adjusted to median line, then it is certain that there are no locks on the other side to prevent its being over-adjusted to left.
If atlas rides dead center there will be no pressure-interference at inter-magnum-atlas foramen. Axis, to be normal, must ride its odontoid in normal relation with fovea dentalis; neither posterior, left nor right.* (Page 440.)
If, however, an adjustment is given upon an atlas wedge-side-slip in a slow, shove, push manner, it can be made to go beyond normal median line, but Innate not recoiling, it will not snap back into median line and stays beyond, where it should not have been shoved or pushed. (Page 442.)
For the reasons given above, it is of great importance that the force of nail point one as applied may be increased by the momentum of the nail hand at point one traveling the given distance during its application. It is also of importance that the axis or atlas will also be caused to travel some distance and to accumulate a certain amount of momentum before the contact of the top of the headrest with its base stops the movement of the top of the headrest.
After traveling some distance the downward movement of the headrest is definitely and abruptly stopped at a predetermined point in accordance with previous adjustment thereof, and this fact gives an increased sud denness to the action of the nail point upon the atlas or axis. As soon as the downward movement is stopped, the headrest is automatically locked in its lowermost position and it cannot interfere or obstruct the natural recoil of the parts which takes place when the hands of the operator are instantly removed at the conclusion of a swift thrust.
It is difficult to understand and explain just why momentum produces a valuable eflect in moving the vertebrae, but extended experience has demonstrated that it does have an important part in producing the direct movement as well as the torque movement of the vertebrae and to some extent the pressure of the nail point is cushioned in its movement downward. In the same way it avoids or reduces the pain which may be caused when that cushioning effect is absent.
Likewise, the recoil of the tissues surrounding the vertebrae is aided by the fact that the top of the headrest is automatically locked to its base at the lower end of the stroke of the operator and cannot travel upwardly until released by the operator.
My type of recoil adjustment, from a technical standpoint, difiers considerably from the recoil produced by the conventional headrest now in common use, because my headrest will facilitate a high rate of speed of the hands of the operator in delivering an adjustment and will also permit a smaller degree of force to be effective when applied to the cerebral region in question.
I do not limit my process to the use of either tension or compression coiled springs, but it is obvious that various equivalent forms of springs, such as blade or plate or forked springs may be substituted for helical springs and can be made adjustable to produce the same effects.
Likewise, the base plate of the headrest may be formed as an integral part of the table or rigidly secured in a given position thereon with the movable top plate pivoted thereto.
Various modifications may be made in the speed, force position and resting upon a headrest movable top plate pivotally mounted thereon with atlas or axis a conventhe has been stopped.
2. The method as described in claim 1, with means the top plate in its lowest position thereby or pressures therefrom are removed.
3. A process or method of chiropractic adjustment (to be applied after taking X-ray spinographs of the patient by which the location, extent, and nature of any subluxation or misalignment in the upper cervical region of the spine of a human being has been shown), which method includes the following steps: (a) placing the patient in a reclining position with the head and neck resting laterally 40 upon a headrest having means for permitting a short downward movement of that portion of the head and neck surrounding the subluxation or displacement and for verse processes of either the adjusting force thereon; and thus releasing the atlas or axis; (0) exerting an then (d) removing the hands pressure as soon as the downward movement of the nail hand has been stopped.
A process or method of chiropractic adjustment to be applied after examining the patient by any of the means in common use by chiropractors to determine the location,
position with the top of a headrest for permitting a short downward movement head and neck resting upon a movable having means thereof and the operator to the neck adjacent one of the lateral transverse processes of either the atlas or axis; (c) exerting a swift downward force thereon; and (d) releasing the pressure as soon as the downward movement of the nail hand has stopped.
