The spinal segments, or the centers of origin of the spinal nerves which are contained in the spinal cord, within the neural canal of the spinal column, originate nerve energy, and also act as reflex transfer stations for all the different varieties of nerve impulses, excited by stimulation of the terminal endings of sensory nerves. The nerves originating from the different nerve centers in the spinal cord vary quite materially in the nature of the vital impulses or energy which they receive, and which they conduct to the parts which they supply. In this chapter it is our wish to consider the influences which the various nerve impulses, generated by the different centers of nerve origin, have upon the many viscera, organs and parts, which they supply. We also wish to consider the results which may be obtained by concussion, when it is given to the spinous or transverse processes of the different vertebrae; the effects of sinusoidal stimulation when administered to the various spinal segments, containing the origin of the spinal nerves; also what may be accomplished by nerve pressure when applied in the paravertebral spaces, or to nerves at or near their spinal exit. The results obtained by the nerve impulses, excited by the above mentioned method of stimulation when applied to different nerve centers, vary quite materially in the nature of the vital phenomena produced within the different viscera and parts of the human organism, hence the great importance of an understanding of this very interesting subject. It is in many cases rather difficult to study, separately, the effects
of the stimulation of a special spinal center, independent of adjacent
ones, because of their very close relation or their juxtaposition within
the spinal cord and also because of their similarity in function.
For this reason, we, in many cases, consider two or more centers of origin
of spinal nerves collectively, and in many cases we study them both individually
and collectively.
FIRST AND SECOND CERVICAL SEGMENTS In the neural arches of the first and second cervical vertebrae, are situated the centers of origin of the first four pairs of cervical nerves. Stimulation of these two segments will excite the centers of origin of these four cervical pairs of spinal nerves and will effect all of the cranial nerves, to which they give off communicating branches. We notice the effects of stimulation of the upper two cervical segments in the head region and in the organs of the special sense as the eyes, ears, teeth, gums, etc. Stimulation of the upper two cervical segments will influence the vagus nerves, because communicating branches are given off to them from a loop or ansa formed from the first and second cervical pairs of nerves, whose centers of origin are in the neural arch of the atlas. Excitation of these upper two cervical segments, or centers of nerve !origin, will also stimulate the phrenic nerves, because their principal centers of origin are contained in the neural arch of the second cervical vertebra. Because of these facts, concussion or other stimulation of these segments or nerve centers of the spine will influence, to some extent, all the viscera supplied both by the phrenic and pneumogastric nerves. Concussion, sinusoidal stimulation or nerve pressure, applied to these upper cervical segmental centers of nerve origin, will produce very decided effects as follows: 1. Stimulates the origin of the upper four cervical pairs of nerves. 2. Stimulates visual acuteness through communicating branches from the fourth pair of cervical nerves, which join the optic nerves. 3. Stimulates the cervical nerves, the branches of which join the auditory nerves. 4. Stimulates and affects the rapidity and regularity of the heart's action by exciting the centers of origin of the phrenic nerves, which are located in the neural arches of the axis and of the third cervical vertebra. 5. Stimulates the centers of origin of the recurrent meningeal nerves and this affects the circulation and metabolic integrity of the brain substance and its covering membranes, which enclose and which supply nourishment to the structural tissues of the brain. 6. Stimulates the functional phenomena of the viscera of the trunk generally, because of the increase of vagus tone, engendered by the stimulation of the centers of origin of the communicating rami joining the vagi from the upper cervical nerves. Loosening up the articulation between the second and third cervical
vertebrae, or continued nerve pressure between the transverse processes
of these vertebrae, will relieve or allay pain in the liver, spleen, gallduct,
pleura or pericardium due to phrenic involvement. Relieving interference
with or stimulating the origin of the fourth pair of cervical nerves in
some cases, is an effectual treatment for paralysis of the diaphragm, and
this also improves the function of vision and also helps to regain or maintain
the normal health of the gums and teeth.
THIRD CERVICAL SEGMENTS In the neural arch of the third cervical vertebra, is located the centers of origin of the fifth pair of cervical nerves, and also some of the cells of the centers of origin of the fourth pair of cervical nerves. Stimulation of the third cervical segment has a very decided influence upon the phrenic nerves, as well as upon the fourth and fifth pairs of cervical nerves, and consequently upon the parts which they supply. Stimulation by concussion, by the sine current or by nerve pressure, applied to the third cervical segment, will produce decided results as follows: 1. Excites myomotor action in the heart's muscles. 2. Will initiate heart action after syncope from different causes. 3. Will accelerate the rate of cardiac action and consequently increases the rate of the pulse. 4. Stimulation of this segment will increase the vaso-motor tone of the pulmonary organs. 5. Since the nerves from this segment control, to a great extent, the rhythm of the heart's action, stimulation will abort arrhythmic paroxysms. 6. Stimulation of the centers of origin of the nerves in this
segment will increase visual acuteness to
7. Stimulation applied to the third cervical segment will cause
a similar effect to excitation of the centers of origin of the cervical
nerves originating in the neural arch of the second cervical vertebra.
FOURTH AND FIFTH CERVICAL SEGMENTS The neural arches of the fourth and fifth cervical vertebrae contain the centers of origin of the fifth, sixth and seventh cervical nerves. Stimulation applied, by use of concussion, the sine current, or nerve pressure, will affect the origin of the contributory branches to the phrenic nerves, which are given off from the fifth cervical nerves, and also stimulates the centers of origin of communicating branches to the middle and inferior ganglia of the cervical sympathetic, which furnish branches to the cardiac ganglion of the sympathetic. The cardiac ganglion supplies the sympathetic and automatic nerve fibers to the thoracic viscera. Mechanical stimulation, affecting the centers of origin of nerves located in the neural arches of the fourth and fifth cervical vertebrae will induce results as follows: 1. Stimulate the vaso-motor tone of the blood vessels of the lungs. 2. Cause contraction of the longitudinal fibers of the air-passages of the lungs. 3. Will check pulmonary hemorrhage from tubercular or other lesions of the lung tissues. 4. Will correct the physical conditions of the air passage of the lungs associated with emphysemic asthma. 5. Will excite cardiac action, following temporary syncope, and will accelerate the rate of the cardiac cycles of action. 6. Concussion of the fourth and fifth cervical segments is an auxiliary measure in the treatment of goiter, especially exopthalmic goiter. 7. The adrenals may be stimulated to secrete a greater quantity
of adrenaline by stimulation of the second, third and fourth cervical spinal
segments, which will increase the phrenic nerve impulses to them.
SEVENTH CERVICAL SEGMENT The seventh cervical spinal segment contains a very important spinal center, which is located within the neural arch of the vertebra prominens. This center contains the cells of origin of the second pair of thoracic nerves, which have a very potent influence or control over the heart and the vasomotor tone of the vessels of the general circulation. Stimulation given by spinal concussion, nerve pressure, or the sinusoidal current, to the spinous or transverse processes of the seventh cervical vertebra, will excite and increase the generation and giving off of vital impulses by the centers of origin of the first, second and third pairs of thoracic nerves and more especially will these measures affect the action of the second thoracic pair of nerves. Stimulation of centers of nerve origin contained within the neural arch of the seventh cervical vertebra, will induce decided and phenomenal influence over the vital and functional activity in all parts of the human organism, and we enumerate briefly as follows: 1. Increases cardio-motor action. 2. Increases the temperature of the body. 3. Increases the temperature of the extremities. 4. Causes contraction of the muscles of the heart. 5. Causes a very decided and general vaso-constriction. 6. Overcomes dilation and valvular lesions of the heart. 7. Will relieve angina pectoris which is due to cardiectasis. 8. Reduces and cures exophthalmic goiter surely and very rapidly. 9. Increases tone of the arterial walls and accomplishes symptomatic cures of aneurism. 10. Acts as an auxiliary treatment for pertussis and controls the paroxysms of coughing. 11. Acts as auxiliary treatment in cases of hay fever, or hay asthma and nasal catarrh. 12. Increases the secretion of hydrochloric acid and is an auxiliary treatment for hypopepsia. 13. Will restore cardiac action when stopped by fainting, drowning or by chloroform inhalation. 14. Constricts the blood vessels of the nose, ears, eyes, lungs and kidneys and the mucous membranes of the nasal cavities. 15. Is an auxiliary treatment in cases of deafness, asthenopia, amblyopia, cataracts and tachycardia due to diminished vagus tone. 16. Is an auxiliary treatment of great value in the treatment of all diseased conditions of viscera and parts which are due to lack of vaso-motor or vagus tone. 17. Concussion of the seventh cervical will stop sneezing, abort
bad colds, overcome paroxysms of chills, equalize the circulation, dispel
local congestion, and overcome vaso-motor paralysis and restore varicose
veins to normal.
FIRST AND SECOND THORACIC SEGMENTS There is contained within the neural arches of the first and second thoracic vertebrae the centers of origin of the third and fourth pairs of thoracic nerves. Spinal concussion, or the sinusoidal current, applied to the spinous or transverse processes of the first and second thoracic vertebrae, or nerve pressure applied to the paravertebral spaces by the side of the spinous processes of the second and third thoracic vertebrae, will stimulate the nerve or vital impulses of the spinal centers of origin of the third and fourth thoracic pairs of spinal nerves. Special phenomena will occur as the result of stimulation of these nerves, and we briefly enumerate them as follows: 1. Will inhibit the heart's action. 2. Will strengthen the cardia motor action. 3. Will constrict the ciliary muscles of the eyes. 4. Will stimulate the parenchyma of the lung substance. 5. Will increase the tone of the sigmoid flexure of the colon
(Abrams).
THIRD THORACIC SEGMENT In the neural arch of the third thoracic vertebra is located the centers of origin of the fifth pair of thoracic nerves. The fifth pair of thoracic nerves help to form the great splanchnic nerves, and are the first and uppermost pair of nerves which join into the formation of the solar plexus, which supplies the abdominal viscera. Stimulation of the spinal centers of origin of the fifth pair of thoracic nerves, by the application of concussion, nerve pressure, or sinusoidal current, to the third thoracic segment will elicit results as follows: 1. Will stimulate the parenchyma of the stomach. 2. Will stimulate the tissues of the throat region. 3. Will cause contraction of the walls of the esophagus. 4. Will cause dilation of the cardiac end of the stomach. 5. Will cause contraction of the pyloric end of the stomach. 6. Will overcome spasms of the cardia and paroxysms of choking. 7. Will increase the symptoms of hypertrophic stenosis of the
pylorus.
FOURTH THORACIC SEGMENT In the neural arch of the fourth thoracic vertebra, is situated the nerve centers of origin of the sixth pair of thoracic nerves. The sixth pair of thoracic nerves join in the formation of the great splanchnic nerves, but the white rami which are given off by the sixth thoracic pair of nerves after joining the gangliated cords of the sympathetic, divide into two divisions, one of which joins the upper, and the other the downward stream of white rami communicantes, and for this reason, the sixth thoracic nerves are considered the central division point of the twelve pairs of the thoracic nerves. Stimulation of the spinal center of origin of the sixth pair of thoracic nerves by the application of concussion, nerve pressure, or the sinusoidal current, applied to the fourth thoracic segment, will elicit results as follows: 1. Will stimulate the parenchyma of the spleen. 2. Will stimulate the central spinal nervous system. 3. Will excite an inhibitory influence upon the heart. 4. Will stimulate the heart muscle through the fourth thoracic nerves. Nerve pressure applied in the paravertebral spaces, between the third and fourth spinous processes, if sufficient to cause sedation, will affect the integrity and action of the pneumogastric nerves, and will diminish the vagus tone and the functions of the viscera of the trunk, which are enervated by the vagi as follows: 1. Increases dilation of the heart and aorta. 2. Increases symptoms of abdominal congestion. 3. Increases the symptom of diminished vagus tone. 4. Will cause dilation of the cardia of the stomach. 5. Will cause constriction of the pylorus of the stomach.
FIFTH THORACIC SEGMENT In the neural arch of the fifth thoracic vertebra are contained the nerve centers of origin of the seventh and eighth pairs of thoracic nerves. The seventh and eighth pairs of thoracic nerves enter into the formation of the great splanchnic nerves, and they are responsible, to a great extent, for the integrity of the solar plexus. Stimulation of the centers of origin of the seventh and eighth pairs of thoracic nerves, by the application of the spinal concussion, or the sinusoidal current, to the fifth thoracic segment will elicit the following results: 1. Will stimulate the parenchyma of the liver. 2. Will stimulate the secretion of the pancreas. 3. Will contract the parenchyma of the pancreas. 4. Will contract the capacity of the gallbladder. 5. Will dilate the pyloric opening of the stomach. 6. Will cause the stomach to assume a vertical position. 7. Will overcome pyloro-spasm but does not affect stenosis or carcinoma. When pyloro-spasm or continued contraction still remains after the stimulation
of the spinal centers contained in the neural arch of the fifth thoracic
segment, then this must be due to stenoses, carcinoma or to some chronic
condition of induration of the musculature of the pylorus.
SIXTH, SEVENTH AND EIGHTH THORACIC SEGMENTS In the neural arches of the sixth, seventh and eighth thoracic vertebrae is situated that portion of the spinal cord which contains the spinal centers of origin of the ninth, tenth, eleventh and twelfth pairs of spinal nerves. The ninth pair of spinal nerves enter into the formation of the great splanchnic nerves and also affect the supra-renal capsules of the kidneys. Spinal concussion or sinusoidal stimulation will stimulate the parenchyma of the adrenals and the secretion of adrenalin. The ninth, tenth, eleventh and twelfth pairs of nerves collectively furnish all the spinal nerves which enter into the formation of the lesser or second splanchnic, and the third or least splanchnic nerves. Stimulation of the spinal centers of origin of the ninth, tenth, eleventh and twelfth pairs of spinal nerves by the use of spinal concussion or sinusoidal stimulation applied to the sixth, seventh and eighth thoracic segments and nerve pressure applied to these nerves at or near their spinal exits will excite the following phenomena: 1. Will stimulate the parenchymatous tissues of the kidneys. 2. Will stimulate the lower two splanchnic nerves and the parts which they supply. 3. Will excite dilation of the lungs because of their connection with the phrenic nerve terminals. 4. Will cause general constriction and will increase the tone of the lower splanchnic zones generally. 5. Concussion of these centers alternated with concussion of the
tenth and eleventh thoracic segments will increase kidney action.
NINTH THORACIC SEGMENT The first pair of lumbar nerves originate from a spinal nerve center of origin which is situated in the neural arch of the ninth thoracic vertebra. Inhibition of the ninth thoracic spinal segment or the center of nerve origin contained therein, by the use of spinal concussion or sinusoidal stimulation, will elicit some phenomena is follows: 1. Will cause dilation of the gall-duct. 2. Will cause dilation of the gall-bladder. 3. Will stimulate the centers of origin of the principal nerve supply to the bladder. 4. Nerve pressure to the ninth thoracic nerves will stimulate the action of the adrenals. 5. Will relieve paroxysms of asthma due to a condition of atelectasis of the lungs. Spinal adjustment to loosen up the articulation between the ninth and
tenth thoracic vertebrae, and to thus relieve interference with the ninth
thoracic pair of nerves, will reach some stubborn cases of asthma which
will not respond to the ordinary adjustment.
TENTH AND ELEVENTH THORACIC SEGMENTS The second, third, fourth and fifth lumbar nerves originate from the spinal segments or centers of nerve origin, which are contained in that portion of the spinal cord, located in the neural arches of the tenth and eleventh thoracic segments. These lumbar nerves ramify and supply the pelvic contents and therefore will stimulate the action and affect the integrity of the pelvic viscera, when they are excited to increased action by the ordinary methods of stimulation, applied to the tenth and eleventh thoracic segments, which contain the centers of origin of the lumbar nerves. The principal and most important phenomenon excited by the stimulation of the ninth and tenth thoracic segments, or the centers of nerve origin contained therein, is the dilation of the vascular system especially, and also of the parenchymatous tissues, of the viscera of the abdominal cavity and vessels of circulation of the splanchnic zones. Stimulation of the tenth and eleventh thoracic segments and consequently of the spinal centers or origin of the second, third, fourth and fifth lumbar pairs of nerves, by spinal concussion or sinusoidal stimulation, will excite the following phenomena: 1. Will cause general vaso-motor dilation. 2. Will cause dilation of the heart and aorta. 3. Will accentuate the symptoms of an aneurism. 4. Will increase the secretion of the intestinal linings. 5. Will increase the peristalsis of the alimentary canal. 6. Will excite dilation of contents of splanchnic zones. 7. Will increase the number or quantity of red blood cells. 8. Will increase the blood volume contained in the splanchnic zones. 9. Will increase the vaso-motor or visceral tone, of the duodenum. 10. Will cause dilation of the liver, spleen, bowels, stomach, pancreas and kidneys. 11. By causing dilation of the spleen we may cause an increased production of red blood cells. 12. Will cause an increase of nutrient supply to the pancreas and increase its action. 13. Will overcome cases of spastic constipation by increasing
the vascularity and secretion of the intestinal mucosa.
TWELFTH THORACIC SEGMENT The neural arch of the twelfth thoracic vertebra contains the spinal centers of origin of all of the sacral spinal nerves. Spinal concussion or sinusoidal stimulation applied to the twelfth thoracic segment, which contains the centers of origin of the sacral nerves will stimulate the pelvic organs supplied by them. One of the most noticeable of the phenomena excited by stimulation of the twelfth thoracic segment, is the contraction of the prostate. Concussion or sinusoidal stimulation of the twelfth thoracic segment will also increase the tone of the caecum. The twelfth thoracic segment, when stimulated, will also assist in the dilation of the organs of the circulation because of the connection of the nerves which are stimulated with the terminal endings of the pneumogastric nerves. Sinusoidal stimulation applied to the twelfth thoracic segment will
affect and increase the tonicity of the sphincters of the bladder and will
assist in overcoming cases of incontinence of urine.
THIRD TO EIGHTH THORACIC SEGMENTS COLLECTIVELY Within the neural arches of the vertebrae, from the third to eighth inclusive, there is contained that portion of the spinal cord in which are situated the spinal centers of origin of all the spinal nerves furnishing contributory branches, which enter into the formation of the solar plexus and of the splanchnic nerves. Stimulation of these segments from the third to the eighth inclusive, which contain the centers of nerve origin of the thoracic nerves, from the fifth to the twelfth inclusive, by spinal concussion or by sinusoidal stimulation, will affect the entire splanchnic zones and general results may be observed as follows:. 1. Will cause dilation of the pulmonary organs. 2. Will cause contraction of the splanchnic viscera. 3. Will increase the visceral tone of the entire splanchnic zone. 4. Will mechanically force blood from the splanchnic zones into the lungs. 5. Will overcome splanchnoptosis or tendency thereto from diminished splanchnic tone. 6. Will overcome any tendency to inguinal hernia and super-imposed weight upon the pelvic viscera. 7. Will overcome tendency to excessively large, fatty-accumulation
within the abdominal walls.
THIRD TO FIFTH THORACIC SEGMENTS In the neural arches of the third, fourth and fifth thoracic vertebrae, are contained the spinal centers of origin of the fifth, sixth, seventh and eighth thoracic pairs of nerves, which enter into the formation of the great splanchnic nerves. Stimulation of these segments or the spinal centers of nerve origin contained therein, will cause stimulation and contraction of the viscera supplied by the great splanchnic nerves directly, and affects in this manner the following visceral phenomena: 1. Stimulates and contracts the liver. 2. Stimulates and contracts the spleen. 3. Stimulates and contracts the stomach. 4. Stimulates and contracts the pancreas. 5. Stimulates and contracts the upper intestines. 6. Increases the amount of the circulation in the lungs.
FIFTH TO EIGHTH THORACIC SEGMENTS The the neural arches of the fifth, sixth, seventh and eighth thoracic vertebrae, are located the spinal centers of nerve origin of the ninth, tenth, eleventh and twelfth pairs of spinal nerves. These nerves furnish all the spinal nerves rami which enter into the formation of lesser or second and of the least or third splanchnic nerves. Stimulation of the fifth to the eighth thoracic segments, containing the origin of the ninth to the twelfth pairs of spinal nerves, by spinal concussion or sinusoidal stimulation, will cause certain results as follows: 1. Will stimulate pelvic organs. 2. Will stimulate and contract the kidneys. 3. Will stimulate and contract the omentum. 4. Will stimulate and contract the mesentery. 5. Will greatly increase the pulmonary circulation. 6. Will dilate the pylorus and contract the cardia of the stomach. 7. Will increase the tonicity of the lower splanchnic zones generally.
NINTH TO TWELFTH THORACIC SEGMENTS In the neural arches, included in that portion of the spinal column consisting of the ninth, tenth eleventh and twelfth spinal segments, are contained the spinal centers of nerve origin of all of the lumbar and of all of the sacral nerves. These nerves ramify and supply the lower portion of the intestines and lower colon, and they are distributed to, and constitute the principal nerve supply to the pelvic organs or viscera and to the lower extremities. Stimulation of the segments from the ninth to the twelfth thoracic segments inclusive, which contain the spinal centers of nerve origin of the lumbar and sacral nerves, by spinal concussion, sinusoidal stimulation, or by nerve pressure applied to the lumbar nerves at or near the points of their spinal exit will affect the integrity or vital function of all of the parts which these nerves directly ramify and supply. Another important consideration, in the application of stimulation to the lower four thoracic segments which will cause stimulation of the lumbar and sacral nerves, is the connection which these lumbar and sacral nerves have with the terminal endings or afferent fibers of the pneumogastric nerves. While the influence of stimulation of the lumbar nerves is to stimulate the lower bowels and pelvic organs which they directly supply, they have quite a different influence, when stimulated or excited, upon the viscera which they supply directly, than upon the organs which they influence in a reflex manner. The spinal centers contained in the lower four segments of the thoracic portion of the spine contain the chief subsidiary centers of dilation contained within the spinal column, and the dilation which is excited by stimulation of these spinal segments, effects both the parenchymatous tissue and vascular system of practically all of the viscera of the abdominal cavity. Alternate and interrupted stimulation of the ninth, tenth, eleventh and twelfth thoracic segments, by the use of sinusoidal stimulation, or by the use of spinal concussion, applied either to the spinous or transverse processes of the lower four thoracic vertebrae, will cause the most decided dilation of all the organs of circulation and of the viscera of the upper two-thirds of the abdominal cavity. Alternate and interrupted concussion of the lower four thoracic segments of the spine: 1. Will cause decided dilation of the heart. 2. Will cause decided dilation of the aorta. 3. Will cause dilation of the vaso-motor system. 4. Will cause an increase of the symptoms of aneurism. 5. Will increase the area of aneurismal dullness. 6. Will increase the murmurs from functional cardiac weakness. 7. Will increase the visceral tone and the dull area of the duodenum. 8. Will excite dilation of the liver, spleen, stomach, kidneys
and intestines.
FIRST, SECOND AND THIRD LUMBAR SEGMENTS The spinal centers of nerve origin are situated above the upper plane of the neural arch of the second Lumbar vertebra, for this reason spinal concussion applied to the spinous or transverse processes of the upper three lumbar segments of the spine, does not affect spinal centers of nerve origin except in case of concussion of the first lumbar segment. Empirically we find that by concussion or sinusoidal stimulation applied to the second lumbar segment, so as to stimulate the nerves coming from that portion of the spine, we excite the most decided and powerful constricting influences and contraction of the abdominal and of the pelvic viscera. The influence of constriction, which is excited or engendered by concussion of the upper three lumbar segments of the spine, causes contraction of the vascular system or blood vessels and also parenchymatous tissues of the viscera and organs of both the abdominal and pelvic cavities. The chief center for spinal concussion or for sinusoidal stimulation to effect a general vasoconstrictor and parenchymatous contraction of the abdominal and pelvic viscera is the second lumbar segment. Concussion of the upper three lumbar segments will produce results as follows: 1. Will excite uterine contraction. 2. Will overcome atonic constipation. 3. Will overcome uterine hemorrhage. 4. Will excite contraction of the liver. 5. Will excite contraction of the spleen. 6. Will excite contraction of the stomach. 7. Will excite contraction of the intestines. 8. Will increase the tone of the colon and intestines.
FOURTH AND FIFTH LUMBAR SEGMENTS The fourth and fifth lumbar vertebrae contain no spinal centers of nerve origin within their neural arches, but they contain a portion of the divided ends of the spinal cord. No doubt the effect produced by concussion of the fourth and fifth lumbar segments is due principally to stimulation of the lumbar spinal nerves where they make their spinal exit. Stimulation of the fourth and fifth lumbar segments by sinusoidal current, by spinal concussion, applied to the spinous or transverse processes, or nerve pressure applied to the fourth and fifth lumbar nerves at or near their spinal exits, will cause contraction of the tissues and capillary circulation of mucous membranes of the bladder and this will overcome an atonic, condition due to myo-motor insufficiency. In closing this chapter in which we have briefly and incompletely given you a general outline of the results obtained by spinal concussion, sinusoidal stimulation or by nerve pressure applied to the vertebrae either separately or collectively, we would now like to make one suggestion which we believe if accepted and applied will be of much use to you and increase the efficiency of your work in spinal therapy. Whenever it is desired by you to increase the functional activity of glandular structures of any of the organs or viscera it is best to apply stimulation, alternately and interruptedly, to both the centers which dilate and constrict the organ which you are treating. By dilating the blood and lymphatic vessels of an organ, we increase the nourishment and liquid supply upon which the glands act and from which they secrete or excrete. By exciting an alternate dilation and contraction of the blood vessels and parenchyma of a glandular organ we will furnish an increased amount of nutritive material, and by the stimulation of spinal centers of nerve origin we will increase the vital energy and functional activity of the cells of secretion and excretion and thus enable them to make more use of the increased nutritive supply. |
