Preface

This little work is offered to the profession without apology for its brevity or its form. It has been prepared because of an immediate and pressing need for such a guide in our colleges, and is offered abroad under the impression that many practicing Chiropractors feel the same need.

It is intended for handy reference and clinical use and is arranged as systematically as possible, style being everywhere sacrificed to utility.

The author lays no claim to the origination of any of the subject matter of this book nor to having invented any of the movements described under Technic of Adjusting. The arrangement and phraseology are in the main original. The intention has been merely to condense into practical and convenient form for students and practitioners certain knowledge now held and utilized in our profession.

The author feels himself indebted to the entire profession for the information embodied in this work, and to scientists of all time upon the results of whose infinite and painstaking research are based our present day advancement; to the many friends and co-workers whose valuable criticisms and suggestions have aided in this labor; and to his students, past and present, who have furnished the necessary encouragement and inspiration for the achievement of this, the author’s first text-book.

The chief merit of this effort—if merit there be—is its honesty. The author has endeavored to set forth fairly and simply the facts and hypotheses with which we have to deal. Its chief offense, in the eyes of many, will lie in its being just what it purports to be—a book on Chiropractic. Constructive criticism and suggestion are invited from all sources, for by our interchange of thoughts we grow.

INTRODUCTION

No two students, approaching for the first time the study of Chiropractic, approach from the same angle. Their viewpoints differ. In order that all may gain as nearly as possible the same viewpoint from which to consider in turn the sections of this book, it will be well if each student reads the entire book before beginning to memorize its parts and convert them into practical working knowledge.

An effort should be made, abandoning all other, to acquire the Chiropractic viewpoint. This accomplished, the rest of the task requires time and patience alone, without waste labor. The section on Vertebral Palpation should be studied step by step, the study of each step being combined with practice in it. Likewise the section on Nerve-Tracing, theory preceding practice. The study of the Technic of Adjusting should occupy those months immediately preceding the commencement of actual adjusting practice and continue during such practice. The chapters on Practice are intended for the student about to enter the field. The table of Spino-Organic Connection can be best understood by those who have studied or are studying the anatomy and physiology of the nervous system.

Let every page be studied with a good medical dictionary open at the elbow of the reader. Pass no word without comprehension, no detail without mastery. He who would seek to modify the life processes of the human body must fortify himself against fatal error with every bit of knowledge he can acquire.

VERTEBRAL PALPATION

Definition

Vertebral Palpation consists in the use of the tactile sense to determine the position, relation, size, shape, and as far as possible the condition, of the segments of the spinal column, in order thus to discover the primary causes indicative of disease.

Or, Vertebral Palpation is the name given the manual examination of spinal vertebrae.

General Propositions

Every palpation should be made with the adjustment of the vertebrae in mind. The record of palpation should be a correct guide as to direction of adjustment. No subluxation impossible of adjustment should be recorded.

The two essentials of correct palpation are accurate perception and correct reasoning. To secure the first, a certain approved manner of using the hands is herein laid down and a considerable amount of tactile sense development by practice is required. Correct reasoning depends upon knowledge of all the important facts concerning the spine and of the rules governing palpation.

Absolute concentration is required and to this end many of the following rules are directed.

Habits of Palpation

Every palpater unconsciously forms habits of thought and action. These habits may be good or bad. We deliberately form a habit of holding the first three fingers closely together or the habit of using a downward glide, but we should avoid the habit of finding certain subluxations because they are usual and expected rather than because they are actually there. For instance, one may easily form a habit of listing every other vertebra in the spine, his whole record thus depending upon his first choice.

Because of this perfectly natural tendency to establish a routine of thought and action and to follow it precisely, it is best not to attempt palpation without the aid of an experienced teacher until after correct habits have been formed. Once formed, a palpation habit, right or wrong, is very hard to break. Many a teacher has expended himself uselessly in the effort to undo some technical fault acquired by the student in a blundering undirected trial.

Facts Concerning the Spine

The spinal column is composed of twenty-six segments called vertebrae, twenty-four movable and two fixed. The movable vertebrae are divided for convenience in study into three sections. There are seven Cervical vertebrae, twelve Dorsal, and five Lumbar in the normal individual. The number of Dorsals or Lumbars may vary by one in a rare case. These variations occur in about one spinal column in each five hundred and are usually in the Lumbar region, which may contain four or six vertebrae. A prominent first sacral spinous process may be mistaken for an extra Lumbar.

Five vertebrae have special names. The first Cervical is called Atlas; the second Cervical, Axis; the seventh Cervical is commonly known as Vertebra Prominens on account of its long and large spinous process, although this long process belongs to the sixth Cervical or first Dorsal instead in 35% of all cases; the large, irregularly fusiform vertebra just below the Lumbars and between the ilia is called the Sacrum; and the smaller one below it, the Coccyx. The latter is occasionally missing.

Each vertebra except the Atlas is composed of a body and an arch; the arch is made up of two pedicles, short, thick plates of bone extending outward and backward from the postero-lateral surface of the body nearer its upper than its lower border, two laminae, thin plates of bone extending backward and inward from their union with the pedicles and joining behind to form the spinous process, and has projecting from it seven processes, two transverse, one spinous, and four articular, two of which are superior and two inferior. The foramen enclosed by the body, pedicles, and laminae is called the neural or vertebral foramen and the canal formed by the connection of these foramina and completed by the ligaments which unite the arches is called the neural, vertebral, or spinal canal. It contains the spinal cord with its membranes and the roots of the spinal nerves. By means of the four articular processes each true vertebra except the first articulates with its fellows above and below.

The body of the vertebra is its largest portion and is joined to its fellows by fibrocartilaginous disks which are sufficiently elastic to permit some torsion and compression. Nine sets of ligaments, including the intervertebral substance just mentioned, bind the vertebrae firmly together. Many muscles are attached to the spinal column.

The intervertebral foramina are openings at the sides of the vertebrae, formed by the notching of apposed pedicles. These openings are surrounded by bone, cartilage, and ligaments and vary in shape in different sections of the spine. They permit the exit of the spinal nerves and their sheaths, the re-entrance of some nerve fibres into the neural canal, and the passage of blood-vessels to and from the cord. The entire philosophy of Chiropractic focuses at the intervertebral foramen because there we find the primary cause of all pathological changes in the body.

The spinous and transverse processes merit particular description since they are the levers by which vertebrae are adjusted and nerve impingements at the intervertebral foramina corrected. But it will be found easiest to describe these processes separately in different sections of the spine and before proceeding to this description, a brief picture of the peculiar vertebrae will be presented.

The Atlas is a bony ring composed of two arches, an anterior and a posterior, separated in the recent state by a transverse ligament. Its body is detached and appears as a tooth-like projection upward from the body of the Axis, the odontoid process, which articulates with the anterior arch of the Atlas and around which the Atlas rotates, a ring around a pivot. The Atlas supports the head upon its lateral masses, two wedge shaped bodies between the anterior and posterior arches, thinner internally than externally. It has no spinous process but merely a tubercle where the laminae join, so that it can be palpated only from the sides upon the tips of its long transverses. The first Cervical, or suboccipital, nerves emerge by a groove above the pedicles instead of through a foramen.

The Axis, or second Cervical, is distinguished by its large, strong spinous process, which is bifid at its tip, by its superior articular processes which rest upon body, pedicles, and transverses, and by its odontoid process, upreared from the body.

The Seventh Cervical, or Vertebral Prominens, usually has a large spinous process, presents no foramina in its transverse processes, or only one, the left, and shows no facets on body or transverse for the rib articulation, as do the Dorsals.

The Sacrum is the largest vertebra; is curved with its convexity backward; is commonly made up of five fused segments; has only rudimentary spinous and transverse processes except the first; and shows sixteen openings, eight anterior and eight posterior, or four on either side of the median line in front and the same number and arrangement behind. These openings permit the exit of the anterior and posterior primary divisions of the sacral nerves separately.

The Coccyx, usually composed of four fused segments, is a triangular bone which articulates with the Sacrum above and is free at its distal extremity. Its portion of the neural canal is open posteriorly and contains merely the thread-like termination of the cord membranes. It is frequently ankylosed to the Sacrum, sometimes in an abnormal position so as to impinge the single pair of coccygeal nerves.

The different regions of the spine show decided differences in structure, though all resemble each other. The Cervicals are smallest, the Dorsals next in size, and the Lumbars largest and strongest of the movable vertebrae. The Dorsals have facets and demi-facets for the articulation of the twelve pairs of ribs with their bodies and intervertebral substance, as well as oval facets upon the anterior aspect of their transverses for articulation with the tubercles of the ribs.

The spinous processes are smallest and usually bifurcated down to and including the fifth. The sixth may show a plain bifurcation, or on any Cervical the bifurcation may be so small as to be imperceptible to touch. The spinous process of the second overlies that of the third so as to make the latter very difficult of detection. Indeed, all cervical spinous processes down to the sixth are harder to palpate than those in other regions, owing to the anterior cervical curve. The processes lie in a groove between prominent muscle ridges.

Dorsal spinous processes are usually single, although the last four, three, two, or one may show plain bifurcation in certain individuals. They are somewhat pointed and overlap, except the lower ones, the obliquity being greatest in the mid-dorsal region and least at the first and last dorsals.

Lumbar vertebrae have broad, flat-tipped spinous processes much larger than the others. The last Dorsal may sometimes appear like a Lumbar in shape, so that the change in shape commonly supposed to mark a division between Dorsals and Lumbars is not always an infallible guide.

The transverse processes in the cervical region are very short and lie close in front of the articular processes. They are pierced by foramina for the vertebral artery and vein, except the seventh, which may have one foramen or none. They are difficult of access for palpation because of their shortness and the amount of overlying muscle, but may be reached from the front and side by drawing back the sternomastoid. They increase in length from the second to the seventh.

In the dorsal region the transverses are larger and stronger and more constant in size, shape, and direction, serving to support rib articulations. They extend in a curved direction outward, backward, and slightly upward from the union of laminae and pedicles and terminate in a large subcutaneous club-shaped extremity which may be readily palpated. The eleventh and twelfth dorsal transverses do not articulate with the ribs and must therefore be used with caution or not at all as levers for adjustment. The dorsal transverses are located on a higher level than the spinous processes. In the case of the upper three dorsals the transverse lies in a plane which would cross the mid-spinal line between its own and the next superior spinous. In the mid-dorsal region the transverse is even with the spinous of the vertebra above, though the relation may vary slightly. The lower dorsals return to the same relation as the upper.

The transverse processes of the Lumbars are relatively light compared with the general structure of the vertebrae and are found just even with the interspace between their own and the adjacent superior spinous process. They vary greatly in size, length and strength and may be used as levers for adjustment only when they are large enough to be clearly palpable through the muscle mass which separates them from the body surface.

Preparation of Patient

In all cases where a complete spinal examination is intended the preparation is essentially the same. Have patient arrange clothing so that the spine is exposed to the touch throughout. Avoid bands of cloth across the spine, as these interfere with the necessary continuous gliding movement of the fingers. Advise the patient, if a female, to wear waist or dressing sack, reversed, and have skirts loosened at the waist. If a man, he should strip to the waist and wear coat or coat shirt reversed.

Position of Patient

This varies widely according to circumstances but for general purposes use position:

(A) Place patient on stool, feet even on floor and body in an easy, relaxed position. This may be modified by asking him to lean forward and rest elbows on knees, evenly, to facilitate Lumbar palpation. Patient’s head may be erect or flexed forward or backward but should never be rotated or laterally flexed during Cervical palpation except for the purpose of locating some particular transverse process.

(B) In emergency cases, where haste is urgent or patient is unable to assume a sitting posture, or as a means of re-verifying previous palpation, place the patient on adjusting table prone, face down. (See Fig. 2.) Remember that with the head lying upon its side the upper dorsal vertebrae will assume a curve with its convexity away from the face. Palpation in position (B) should precede every adjustment and, to guard against error, should be considered as a necessary preliminary to the movement of any vertebra.

(C) For palpation preparatory to using the Rotary, the Break, and other moves, have patient lying on his back with his head projecting beyond upper end of bench and resting on the hands and wrists of the palpater, or have the patient’s head rest on the bench, a less accessible position.

General Observation

Each spinal examination should begin with a general survey by which curvatures, marked prominences, etc., may be appreciated. Frequently some very important fact may be noted which would escape attention upon minute examination.

THE RECORD

The record of spinal palpation, when completed, should be an accurate history of the irregularities found in the spine and an accurate guide to adjustment. It must be brief and concise as well as readily comprehensible. One should be able to see at a glance any desired point on the record, so that it may be used during the adjustment without undue loss of time or attention. Obviously the introduction of any useless mark or sign, such as the inclusion of a number and blank space for each vertebra of the spine, or all possible subluxations with indications as to which do or do not exist in the given case, is a mistake.

The record should contain three parallel columns. In the first column place the number of the vertebra chosen for adjustment. In the second, place the direction of subluxation. In the third, place the word or sign which stands for the indicated movement for correction.

Number of Vertebra

The letter C is used to indicate Cervical, D Dorsal, L Lumbar, and S Sacrum in the record. Immediately following the letter which designates the region, place the number which shows the position in that region occupied by the vertebra in question, the relation of that vertebra to its fellows. For instance, the third Cervical vertebra is C 3, the eleventh Dorsal D 11. To the S for Sacrum append B or A to indicate that the Base or Apex is described as to position. This locates the subluxation. For a record of full spine palpation it is unnecessary to use the letters C, D, or L more than once, as subluxations are recorded in the order of their occurrence from above downward. A dash should always follow the number of the vertebra to separate it from the letters in the second column for convenience in reading.

Direction of Subluxation

The directions considered in palpating or recording subluxations are six in number, namely:

As the fingers glide down the spine the posterior vertebra is the one which interposes itself in the path of the fingers, forcing them to describe an outward curve. It is the hill on the automobile road which forces the surmounting of a curved departure from the evenness of the road. It is relatively posterior to its fellows above and below.

The anterior vertebra, to the gliding fingers, means a depression, a valley. It causes the fingers to dip inward from the level of their course.

The right or the left subluxation is appreciated by running the tips of the fingers down the sides of the spinous processes. It really indicates rotation of the whole vertebra more often than any other malposition.

We say that a vertebra is superior when its spinous process is nearer the one above than the one below. It requires a measuring of relative distances. The degree to which a vertebra is superior is measured, not by its actual closeness to its fellow, but by the relation between the space above and the space below.

Likewise a vertebra is inferior when it is closer to its fellow below than to its fellow above.

Anterior subluxations are rarely recorded as such, except of the Cervicals or the last Lumbar, because no means of properly adjusting them is known to Chiropractic.

Order of Letters

In the second column, that devoted to direction of subluxation, the letter P or A should appear, if at all, as this antero-posterior relation is the first thing to be determined concerning any individual subluxation chosen except the Atlas. With the Atlas the first letter will be R or L. Next the laterality or rotation is indicated by R or L in every case except Atlas subluxation. Finally the S or I indicates the last point to be determined, the approximation of the vertebra to its fellows. This last letter usually shows thinning of intervertebral fibrocartilage, which will be discussed elsewhere.

If you desire to emphasize any direction as being more important than another, underscore the letter which stands for that direction with a single line. If two directions are to be emphasized, one more than another, underscore the one with two lines and the other with one. For example, if a vertebra is found to be quite decidedly posterior, more plainly to the right, and slightly superior, the record will show it thus: P R S.

Movement for Correction

This is indicated in the third column, separated from the second by a dash, by means of some brief word or words which describe a certain movement used in adjusting. The descriptive words and terms used in this work are all given and explained under Technic of Adjusting. (See p. 89.) Each word or term stands for a definite method of procedure. The best movement for the correction of any subluxation of any vertebra may be found by reference to the section on Preferable Adjustments, p. 155. If other terms are more familiar to the student, or in time replace those which are now common usage in the profession, they will be brief and clear and may be easily substituted for those given.
