The claim stated plainly
Ida's most direct statement of the verticality doctrine came in her 1974 Cal Poly Healing Arts lecture, where she addressed a mixed audience of practitioners, scientists, and bodywork-curious laypeople. The premise she laid out was deliberately mechanical and deliberately physical: order in the myofascial system is evoked by balancing structures around a vertical line, and the gravitational field — passing through that line — either supports the body or breaks it down. This is the structural skeleton on which everything else in the doctrine hangs. The nervous-system consequences come later in her teaching, but they all depend on this foundational claim about line and field. Notice that she frames it as evocation, not imposition: the order is brought out, not pressed in. The body already contains the disposition to be vertical; the practitioner's role is to remove what prevents the disposition from expressing itself.
"We know that order can be evoked in the myofascial system of the body by substantially balancing the myofascial structures about a vertical line. We know that logically in body mechanics, we can expect that the vertical lines of that force manifesting as the gravitational field can either support and reinforce a body, or it can disorganize it and presumably passing by presumably passing through and being part of it, it can destroy and minimize the energy fields surrounding it."
Ida states the verticality doctrine in its compact form to the Healing Arts audience.
The vertical line she describes is not abstract. It is anatomically specific: ankles, knees, hip joints, lumbar vertebral bodies, shoulders, ears. She returns to this enumeration repeatedly across the lectures, treating it almost as a checklist by which the practitioner verifies the work. But she also marks a distinction that becomes crucial later — the static verticality taught by orthopedic schools is not the verticality that interests her. Her verticality is the precondition for a different state, one in which the body is no longer fighting gravity and the nervous system, freed from that fight, can do something else.
The verticality every school teaches, and what they leave out
Ida positioned her work against a century of postural pedagogy. The vertical alignment of ears, shoulders, hips, knees, and ankles was not her invention — it had been taught at Harvard, by Mensendieck, by every accepted school of body mechanics. What none of these schools offered, she argued, was a means of achieving the alignment they prescribed. They could measure deviation from the vertical; they could not produce verticality. The reason, she came to believe, was that they treated the body as a fixed object and prescribed exercise or posture to compensate for its fixity. Her own break with this tradition came from a single recognition — that the body is not fixed. It is a plastic medium, susceptible to reorganization at the level of its connective-tissue architecture. The vertical line, in her work, is not a target to aim at but the consequence of having reorganized the medium.
"All those prickles pointing straight toward the center of the earth. If the lines are substantially vertical. This is a static verticality, however. This is the verticality taught by every accepted school of body mechanics operating in this century, and the Harvard group heads the list. All schools of body mechanics teach this measuring stick and verticality, but no other school of body mechanics teaches how to achieve it. But because the body has an unforeseen, unexpected quality, it can be done. The body is a plastic medium. Now this is incredible, and twenty five years ago, no one would have believed this statement. Fifty years ago, they'd have put me in a nice sunny southern room. You've given me pretty good care, maybe. But the body is a plastic medium, and you're going to hear that several times before we get out of here today."
She marks the difference between her verticality and the verticality of the postural schools.
The second great evening of public teaching, recorded in the Topanga sessions, treats the same distinction from a slightly different angle. There she introduced the contrast between structure and posture — structure as a property of relationship between parts, posture as something done to maintain a placement. Posture is effortful; structure, when balanced, is automatic. The slippage between these two words, she argued, is where conventional body-mechanics pedagogy loses the thread. She insisted that a student meditate on the words themselves before continuing.
"This constitutes structure. Now posture is something else again. And the boys that devised the word posture knew what that something else was because the word posture means it has been placed. It is the past participle of a Latin word, to place, and it means it has been placed. And when you use the word posture, you are saying it has been placed. Somebody has placed something somewhere. Somebody is maintaining the placement of something somewhere. Somebody is working to keep something placed somewhere. And I guarantee that there is no one in this room who doesn't know that in this day and age of the what is it? Nineteen twentieth century, last part of it, last quarter of it, that to keep any of these bodies in posture takes effort, constant continuous effort. And when you have to make effort concerning anything in your body, it's a very bad sign. You don't usually interpret it in view of the next words. But as I see a man struggling to maintain posture, I know that he is losing his fight with gravity. That's one item. And I know that his structure is not in balance. Because if his structure is in balance, his posture automatically is good. Posture is what you do with structure. Structure is the way you relate parts of the body to each other."
She distinguishes structure from posture, and locates the cost of confusing them.
Why an animal becomes vertical at all
By 1976, teaching the advanced class in Boulder, Ida had begun framing the verticality doctrine in explicitly evolutionary terms. The conventional medical-school story — that human beings were designed for four legs and that their structural troubles all stem from insisting on two — she rejected outright. Standing upright was not a defect to be compensated for. It was, in her telling, the consequence of a nervous-system change that had selected for the upright posture and then been further changed by it. The two ideas run in a loop: the demand for verticality reshapes the nervous system, and the reshaped nervous system makes deeper verticality possible. This is not idle speculation on her part — she advances it as a working hypothesis about why the work she does has the effects it has.
"happened, that as it became possible for some energy and so forth to act on the nervous system of gradualism of experimental animals that were trying to become upright, that have changed their nervous system. And so you get an entirely different nervous perception, nervous direction, an entirely different animal comes out."
Ida advances her speculation about the co-evolution of verticality and nervous system.
The mechanism that makes the upright stance possible at all, in her telling, is segmentation. A snake cannot stand; a tortoise cannot stand; a whale cannot stand. What permits the human animal to align itself with a vertical is that the body is constructed of discrete segments — head, thorax, pelvis, legs — connected by myofascial tissue that can be reorganized. Segmentation is the structural precondition for verticality, and verticality is what gives access to gravity as a supportive rather than destructive force. The whole argument is a chain: segmentation makes verticality possible, verticality makes gravitational support possible, gravitational support makes nervous-system reorganization possible.
"Perhaps it does indirectly, but I'm sure you'll hear what I'm saying to you concerning the difference. Now why has it happened in the course of the ages that men have gone political, They are able to do it by means of two constituent items, but the one, the most obvious one is the segmentation. Now let's lay the other one down for a bit. Why do they want to get It's only true after they get adjusted really balanced to the vertical. But you take This is a piece of velvet that was given to them. But I think that the answer below the velvet is something else again. I think it has to do with somehow that nervous system starting to change and demanding the field of energy which enhances the operation of the nervous system. I think this is one of those this is pure unadulterated Guess guess what?"
She names segmentation as the structural precondition for the upright animal.
The lawful's task: study how to bring humans into verticality
Having sketched the evolutionary argument, Ida then turns it back on her students as a directive. The medical-school story — that human pain is the price of two-legged standing — is not just wrong, she argues; it is the wrong question. The question is not why standing produces breakdown but how a body can be brought to a verticality so balanced that gravity ceases to break it down. Her students, the lawfuls (a term she occasionally used for those certified in the work), are charged with studying the details of that bringing-into-balance. This is one of the rare moments in the recordings where she names the nervous-system stakes of verticality directly, and frames the practitioner's task as a study problem rather than a technique problem.
"Now your job as lawfuls is to study the details as to how you get human beings into this verticality so that gravity is not breaking down. And this is a different point of view from all the troubles that a human being has is due to the fact that he's standing up on two legs instead of walking on four. It's a very different point of view. It's a point of view which is taken into consideration something which we tend to call spiritual."
Ida charges the advanced students with the operative question.
Earlier in the same lecture she had described the appearance of a second nervous system — the central nervous system layered atop an older emotional nervous system — as itself a consequence of evolutionary pressure for faster response. This framing matters because it positions the verticality work as operating across both nervous systems at once. The Structural Integration practice is not aimed at the central nervous system alone; it reaches the older system through the position of the vertebrae and the autonomic chain that runs in front of them.
"us, that we decided we had to have a different type of nervous system that could demand a faster response from the flesh. And then this was necessary to survive. So then we begin to develop a second nervous system, the central nervous system. But the emotional response is still in the old nervous system. Emotional response is still in in the consolidation that occur at various places along that old nervous system. So we are now at a place where we have to take a brand new look at all this."
She sketches the layered nervous system she takes as her object.
The autonomic chain runs in front of the spine
The most specific anatomical claim in Ida's verticality-to-nervous-system bridge is that the autonomic nervous system — the sympathetic chain and its plexi — lies along the front of the vertebral bodies. The implication, as she develops it in the public-tape interview on the third hour, is that the position of each vertebra determines the nutrition, the metabolism, and the well-being of the autonomic structures adjacent to it. A jammed vertebral column produces a strained autonomic chain. A balanced vertebral column produces a chain that can function. The clinical reach of the verticality work, on her account, extends to whatever the autonomic chain innervates — which is almost everything below the level of conscious motor control.
"And if it's gone Now if the tent pole is in place, place, then you begin to get an entirely different functioning in your autonomic nervous system which is dependent on the tent pole, as well as your central nervous system. But you see the functioning of that whole automatic chain is going to be affected by where those lumbar vertebrae are and how happy they are in their awareness. That's far out from me. Well, but you've made it. You know, I was thinking that the autonomic nervous system is gonna be happy depending on what the vertebra you're doing. I The autonomic nervous system runs down right in front of the vertebra. So if the vertebra are all jammed up and one is in front of the other and so forth, it's putting strain on that autonomic nervous system. It's interfering with the metabolism to the nervous system. That's an entirely new concept for me. Mean this class, not just today, but this well, in learning, I learned that there was skin, there was fascia, there was muscles, was bone, there was nervous system, etcetera, and they were like envelopes, one around the other."
Ida walks a student through the mechanism that links vertebral position to autonomic function.
The same claim returns at the upper end of the spine when she discusses the seventh hour and the work on the cervical vertebrae. Just as the lower autonomic plexi depend on the position of the lumbars, the upper plexi — the superior, middle (stellate), and inferior cervical ganglia — depend on the position of the cervical vertebrae. The whole autonomic chain, top to bottom, is held in proximity to the vertebral column and rises or falls with it. This is why she insists, against the chiropractic and osteopathic traditions, that organizing a body cannot be reduced to manipulating individual vertebrae — the chain has to be considered as a unit, and the unit responds to length and balance rather than to local adjustment.
"Because just as the position of the vertebra further down the line determines the position and the nutrition and the well-being of the autonomic nervous system down the line so the position of the cervical vertebrae determine the position of the upper three autonomic plexi, a cervical plexi, superior, inferior, and medial."
Ida extends the autonomic-chain principle to the cervical plexi.
From vertical to horizontal — the joints as hinges
In the 1971-72 Mystery Tapes session Ida and a circle of students — Peter Melchior among them — work through the relationship between the vertical line and the horizontal hinges of the body. The articulation that emerges from this dialogue is that horizontals are not independent of the vertical; they are the outward expression of it. If the ankle, the knee, and the pelvis present truly horizontal axes, the vertical is established; if the vertical is established, the horizontals must follow. This circular formulation appears again and again across the recordings. It matters for the nervous-system claim because it explains why the work cannot be reduced to spinal manipulation: the verticality of the spine is dependent on the horizontality of the hinges, and the hinges are reached through the myofascial structures rather than through the joints themselves.
"Well, me start with an assumption that the most efficient movement of the erect human is by movement of joints that are defined by a horizontal axis. Particularly at the ankle, the knee and the pelvis. And if that's so, if that's what, if that's the equipment that we have in an evolutionary sense, that's what's available to us, that's the optimum functioning of the individual, then it would follow that the balanced organism would be so constructed that when it's in balance these hinges would be horizontal. You know, I sort of go around that and be secular. You know, taking advantage of that circularity, behind which everybody lived and hides from time to time. And so when the, what determines the actual configuration of structure is the combination of weight and tension held both in the fascia and in the musculature. And the alignment of the supporting structure of the bone."
Peter Melchior articulates the hinge-axis premise that organizes the verticality work.
Ida picks up the same theme in the 1975 Boulder advanced class, but with a corrective edge. Her students, she observes, have begun to chase horizontality directly, looking for horizontal hinges as a primary target. This is backwards, she says. The vertical comes first; the horizontals follow. Length is what the practitioner is inserting into the body from the first hour onward, and length is verticality. When length is sufficient, the spool-and-spring image she uses — vertebrae as spools on a spiral string — comes into balance and the horizontals appear of themselves. The recovery of the vertical-before-horizontal order is one of the persistent disciplinary moves of her advanced teaching.
"But before you horizontalize the pelvis, that vertical consideration comes in first, in my opinion. What do you think about this? I agree. I've what I've been noticing a lot of people's processing is they don't always get the verticality. That's right. They're too concerned with the horizontal. That's right. That's right. And in the old days of my teaching, you never were aware of this horizontal until it appeared, and it didn't appear until the late in the sixth hour, the seventh hour. Then it had disappeared in the eighth hour. Then it reappeared in the ninth hour. You see what I'm talking about. The horizontal is a sign that the particle has been cleared. Now horizontalizing the pelvis is the goal of the whole trip. But before you reach for that word and that concept horizontal, reach for the word and the concept vertical. Because when you have the vertical in, the horizontal will be there. It cannot be otherwise. So are we talking about verticals in the sense of lengthening? We are indeed. Uplifting and lengthening. We are indeed."
She corrects students who are reaching for horizontality before verticality.
Length, the lumbodorsal hinge, and the nervous-system payoff
Across the 1975 Boulder transcripts Ida insists that lengthening the trunk is what permits the autonomic chain to function as it should. The mechanism, as she walks her students through it, is straightforward but easy to miss. By organizing the quadratus and lifting the twelfth rib off the iliac crest, the practitioner creates space for the lumbar vertebrae to straighten. The straightening of the lumbar vertebrae lengthens the trunk. The lengthened trunk creates room for the autonomic chain that runs in front of the vertebrae — the autonomic chain that has otherwise been compressed. This is the doctrine of length stated as a nervous-system mechanism. It is also the conceptual bridge between the third-hour quadratus work and the later hours' work on the autonomic plexi.
"How does the trunk lengthen? How does the trunk lengthen? What is the mechanism? Organizing the quadratus, the twelfth rib becomes more elevated. Elevated. And then? Well, let's do this together. The trunk lengthens by straightening the spine. Yes. So the You see, stretch the soft tissue and then the the hard tissue, the tent pole can go into place. Oh, okay. And if it's gone Now if the tent pole is in place, place, then you begin to get an entirely different functioning in your autonomic nervous system which is dependent on the tent pole, as well as your central nervous system. But you see the functioning of that whole automatic chain is going to be affected by where those lumbar vertebrae are and how happy they are in their awareness."
Ida builds the chain from quadratus to twelfth rib to lumbar straightening to autonomic function.
The 1974 IPR lecture extends this with a developmental account of the spine's major junctions. Ida names five — occipito-cervical, cervical-dorsal, dorsal-lumbar, lumbosacral. The lumbodorsal hinge is the most important for the vertical line, and it is the last to be established. This is not arbitrary, she argues; it follows from the order of operations in the recipe. The trunk has to be supported from below before the lumbodorsal hinge can find its balance, and it has to be lengthened before the hinge has room to open. When it does open, what was previously held by muscular effort begins to lever itself into place — a senior student describes it almost as an internal lever system that lifts the head and neck. This is the experiential signature of a vertical line that has been earned rather than imposed.
"to be a place where that group of vertebrae with that configuration meets the group of vertebrae with this configuration and there is room for adjustment. Now this is true of every one of the major vertebrae, of every one of the major junctions. They are uniting pieces of anatomy. I recommend that expression. You like that? I thought you did. Pieces of anatomy that have different functions. The atlanto cervical or occipital cervical is cervical dorsal. In your mind's eyes see the change in structural configuration. The dorsal lumbar and perhaps the lumbosacral in that the sacral is the representative here of the pelvis. Now, that's the story of your junctions. Now, which is the most important in terms of your straight line? The luminal dorsal is the most important in terms of the straight line. And it is the last one to be established if you are processing. And you know this, you have seen it, you have seen it through the last month, you have seen how you work on a guy to get enough freedom, take Margery for instance, she still has not got that lumbar dorsal established. And one of the reasons she hasn't is because those ribs are so far down that there cannot be movement between the dorsal and the lumbars until the ribs get raised up."
Ida names the five major junctions and identifies the lumbodorsal as the operative one for verticality.
What is striking in this articulation is that Ida treats the spine not as a column but as an assembly of regions with distinct functions, connected through hinges. The vertical line is not the line of any single column but the consequence of the proper relationship between regions. This is why she insists, against schools that focus on individual vertebrae, that the spine must be understood as a unified mechanism with internal differentiation. The autonomic chain runs alongside the whole of it, and its well-being depends on the unity, not on any local adjustment.
"Well one of the things that impresses me experientially as well as as I try to invest that skeleton with some flesh Is the essential nature of the spinal, not the spine as such, but the spinal structure? It is again as though a body was something built around a spine. Now a lot of people have had this idea, the osteopaths have had it and the chiropractic have had it. But none of them have ever gotten out of their spine a unified something going along there. They always manage to have a series of bony segments and that's what they figure a spine is. Now this is not my concept and this is not the concept around which structural integration works. You have to get that picture of the whole spine, the whole spinal mechanism as a unit, as a unit of united areas. It is a much more sturdy sort of a concept than, for example, the chiropractic concept, where you simply have bones that you push around. And I'd like you to take this idea home with you and try to get more reality on it. As you yourself get more processing, you will understand this. It is quite impossible, I think, to understand this before you have had the kind of processing that puts these things together. And this is the reason why, at this point, the whole world, relatively speaking, accepts chiropractic, accepts osteopathy, because that is the level where their bodies are living."
She insists that the spine be understood as a unit, against the chiropractic and osteopathic traditions.
Lying down: the horizontal as latent vertical
One of the more subtle teaching moments in the Boulder transcripts comes when Ida explains why the work begins with the client lying down. The reason is not just mechanical — though it is partly mechanical, since the gravitational pull on a recumbent body is reduced compared to standing. The deeper reason is that the verticality the practitioner is trying to establish appears, when the body is supine, as a length along the floor. The horizontal of the recumbent spine, in other words, is a latent vertical. When the body stands up, that length becomes height. The transverse horizontals of the joints — the hinges Peter Melchior had described — are then the outward expression of the inward verticality. Ida adopted the catechism phrase: outward and visible sign of an inward and spiritual grace. The phrase was deliberately old-fashioned and deliberately precise.
"And then you see as you get that vertical lying on the floor, now being one of the horizontals, you begin to see the transverse horizontals come out because the transverse horizontals are the outward and visible sign of the inward and spiritual verdictality. Those horizontals are nothing more than that. And sometime you and you are going to have to get together and make a more realistic something with which people can get a hold of this concept."
Ida names the transverse horizontals as the outward sign of an inward verticality.
The verticality, in this telling, is doing something specific by the time the body stands up: it is allowing the lumbar vertebrae to fall back into their proper position, which allows the psoas to take its place along the line, which allows the autonomic plexi that lie on or near the psoas — the lumbar plexus in particular — to function without compression. This is the mechanism by which the abdominal organs find their innervation restored. It is also why the fifth-hour work, which addresses the psoas and the floor of the pelvis, is treated by Ida as one of the most consequential hours for autonomic function.
"you go into the abdomen if you go in there on the first hour but certainly you're going into it as you give that pelvic lift And as you see that belly wall fall back, you are entitled to say, Eureka, I have made it. Because now you are beginning to call on the psoas to take its place in the line. Now you see there's not there's not a horizontal in this whole trip, awful lot of vertical because you are allowing those anterior lumbars to go back and become balanced lumbars. Now you see there's another factor in there and that factor is connected with the fact that your autonomic plexi lie on or very near the psoas. And that as the psoas falls back, the lumbar plexus gets its work out. And the lower plexi side below that, even they get something on the workout through that. Now realize that that falling back of the lumbas and turning under of the pelvis is not an artificial movement."
She describes the psoas falling back into line and the autonomic plexi receiving the consequence.
The fascia as the medium through which verticality is built
Ida's 1974 Healing Arts lectures were also the venue in which she made her most direct claims about why the fascial body is the access point to everything else. The fascia is the supportive organ — the structure that keeps the body from falling on its face. It is also the organ through which pressure becomes structural change. In the second Healing Arts lecture she elaborated on what the addition of energy through the fingers and elbows of the practitioner accomplishes: it changes the relation of the fascial sheaths, balances them around the vertical, and produces a body that incorporates increasing order. The change registers first as a static stacking and then, as the work deepens, as a dynamic balance. The psychological and behavioral changes she described as consequence rather than aim.
"And I'm talking here about energy being added by pressure to the fascia, the organ of structure, to change the relation of the fascial sheaths of the body, to balance these around a vertical line which parallels the gravity line. Thus, we are able to balance body masses, to order them, to order them within a space. The contour of the body changes, the objective feeling of the body to searching hands changes. Movement behavior changes as the body incorporates more and more order. The first balance of the body is a static stacking, but as the body incorporates more changes, the balance ceases to be a static balance. It becomes a dynamic balance. These are the physical manifestations of the increasing balance, but there is an outgoing psychological change as well toward balance, toward serenity, toward a more whole person. The whole man, the whole person evidences a more apparent, a more potent psychic development. This means that the rate that the ratio man energy to gravity energy energy has changed has increased. The ratio has therefore increased the force available to reverse the entropic deterioration. That is and greater. Our world is no longer running down."
Ida describes how energy added to the fascia produces the verticality and what follows from it.
What this clarifies about the verticality-and-nervous-system claim is that the nervous-system change is not a separate aim of the work but a consequence of the fascial reorganization. The practitioner does not address the nervous system; the practitioner addresses the connective-tissue medium. The nervous system, embedded in and constrained by that medium, reorganizes itself as the medium reorganizes. This is the same principle Ida would later articulate in the 1976 Boulder class when she warned students against trying to swing themselves into the nervous system directly — the access route is through the tissue, always.
Valerie Hunt's measurements: a downward shift in control
Among the colleagues whose work Ida cited in defense of the verticality-to-nervous-system claim, Valerie Hunt was the most directly empirical. Hunt — a UCLA physiologist who had been measuring neuromuscular patterns in the Structural Integration population — reported at the 1974 Cal Poly Healing Arts conference that the changes she was seeing after the work could not be explained by postural alteration alone. The bioelectric signature of movement shifted in ways that suggested the control of movement had moved to a different level of the nervous system. Hunt offered this as a hypothesis rather than a proof, and Ida cited her with the same caution. But the framework was congenial: if verticality reorganized the relationship between the body and gravity, and gravity was the field through which the nervous system operated, a downward shift in motor control was exactly what the doctrine would predict.
"There are three major upstream sources. Like having a switch, a three way switch on a light, a source of energy. It can be turned on at various places. Ordinarily, when we turn on that switch, we get exactly the same light or energy source at the other end. But in the instance of the human body, that is not true. If we turn on the muscle or send the stimulus from the spinal cord, we get what's called a very low frequency. It is the kind of thing you experience when you're out playing golf and that one time you hit that ball magnificently and it took off and it was no effort, and you're always looking for it again. We find that when people become more skillful in a particular high level task, they become what we call more finalized. There's a lot of research on this to show that the frequency actually changes. I think that Rolfing brings a downward shift. There is another level of control that we call the midbrain, and this area also can turn on muscles. We can operate on it. It is one of our very basic areas for some of our primitive movement, and it primarily innervates the great large joints of the body and those which are proximal, such as the shoulders and the hips and the trunk one of the areas that Rolfing works a great deal upon. This has a tendency to produce a very rhythmic quality of movement. And then there, of course, is that cortex that louses us up in so many ways. It can do those fine things with the hand and the beautiful nuances in the face, but it is totally inefficient, inefficient. It louses up, its pattern is not well established. Two muscles counteract each other at the same time, And my feeling is that this smoother energy release that comes after rolfing is based upon a downward shift in the control in the primary control."
Hunt proposes the empirical signature of the change: a downward shift in motor control.
Hunt followed this with a related observation about co-contraction. Before the work, she had been measuring patterns in which antagonistic muscles fired simultaneously, dissipating energy without producing movement. After the work, she was seeing sequential contraction — agonist firing, then antagonist firing — with measurably greater efficiency. This pattern is what Ida had been describing for years when she spoke of the body 'doing its own work' rather than working against itself. Hunt's instrument turned the descriptive claim into a measurable one, and Ida used her data as the empirical complement to the structural argument.
"We have every reason to believe that this project will lend itself to measurement. Her findings seem to be saying loud and clear that as a man approximates the vertical, that is ears over shoulders, shoulders over hips, hips over knees, knees over ankles, certain very significant changes occur in the kind of neuromuscular behavior, can and these changes can be registered and they can be recorded by electromyographic and electroencephalographic measurements. Ralfas in general are not sufficiently scientifically sophisticated to demand measurements. They're willing to settle with contour, with form, without with recognizing the outward form of contour."
Ida quotes Hunt's framework for what verticality does to neuromuscular behavior.
Julian Silverman's energy model: viscous to elastic
A second scientific frame for the verticality claim came from Julian Silverman, a physicist who attempted to model the body as an ensemble of energy-generating organs connected by networks of elastic and damping elements. In Silverman's reading, the structural problem before the work begins is that the viscous elements outweigh the elastic ones — meaning that no single joint can move without dissipating energy through the entire system. The work, in his terms, converts viscous interconnections into elastic ones. The result is not just freedom at any one joint but the possibility of resonant energy flow between joints. Ida did not always engage with this level of formalism, but she recognized it as compatible with the verticality doctrine: the vertical line, properly established, is what permits the various energy sources to operate in synchronous, often reciprocal patterns.
"Specifically, we have a mechanical system of joints, articulations, energy sources springs and viscous damping forces Action at a joint is then represented by a lever powered by an energy source driving a spring and dashpot parallel. These various module organs would be interconnected by networks of parallel combinations of elastic and damping components. Considering first action of a single joint, we see that the viscous elements greatly outweigh the elastic ones, motion will be impeded and energy wastefully dissipated. The problem is compounded when one realizes that all of the individual energy sources are interrelated through myofascial investments. If we examine a simple act such as walking in the light of this model, it is apparent that for maximal efficiency these various energy sources must operate in precise, synchronous, often reciprocal patterns. If the interconnecting networks are overly viscous, then no one joint can be moved without dissipating energy throughout the entire system. If by some process the viscous elements could be changed into more elastic ones, what would the model predict? Clearly, an increased capacity for energy flow between joints is to be expected. Know that this itself will affect an overall change toward more rhythmic efficient energy flow is not true. If the individual elements are still unbalanced with respect to each other, then the increased capacity for energy transfer may be of little use or may even give the appearance of less synchronicity. This is so because all of the modules have their own intrinsic frequencies of oscillation. And if they are in wrong phase relationships with each other, their energies may tend to collide or interfere with one another. What then is the resolution of this problem? The various energy sources must then be modified so as to bring the system as a whole as near to a resonance condition as possible. Returning briefly to the world of structural integration, the first few sessions, mainly the first, are devoted to reworking the superficial fascia."
Silverman proposes a physical model in which the verticality work reduces viscous loss and enables resonant flow.
What makes the Silverman model relevant to the nervous-system claim is the recognition that synchronicity itself depends on phase relationships, and phase relationships are set by the nervous system. A body in which joints are mechanically free but neurologically uncoordinated will not move with the smooth efficiency the work produces. The verticality has to be matched by a neuromuscular pattern that uses it. This is what Hunt's measurements were registering at the empirical level and what Silverman's model was sketching at the formal level. The two scientists, working in different idioms, were describing the same convergence.
What changes when the body is vertical
The clinical signature of a verticalized body, in Ida's account, is not just better mechanics. It is a change in the man himself. In the 1974 Open Universe Class she quoted Hunt directly on the consequence: as the energy fields of the body parallel the gravitational field, the nervous and glandular systems are less bedeviled by gravity, and the man begins to differentiate more, feel more, register insights he had not been receiving. Fritz Perls had remarked on this — the insights he was having while undergoing the work, he had said, were qualitatively different from anything he had encountered before. Ida treats this not as a metaphysical claim but as a structural one: the verticality permits the nervous system to do what it could not do while it was holding the body up against gravity.
"As those two energy fields parallel one another, it is then that gravity becomes a supportive factor. As the nervous and glandular fields of the man are less bedeviled by gravity, the man apparently changes. His behavior changes. The man, we might say, becomes more human. He differentiates more. He feels more. He feels his own mental processes as being less confused, as being more adequate. He suddenly feels himself as the subject of more and more important insights. This is what Fritz Perls used to say about structural integration. He says, You just can't believe the insights I have had since I have been working with them. As a new technique, we know that we need validation, a fitting into conventional acceptances. One of our attempts at validation is going on in the laboratory of UCLA right now, and is stopping right now. And I think that later Doctor. Hunt may offer some of you the opportunities of being models in there, if you care to see her later on. This validation is going on under Doctor. Hunt's direction, and as I know and as you know, she needs no introduction. It is noteworthy that Doctor."
Ida reads Hunt's account of what a verticalized nervous system does.
The dynamic versus static distinction returns here. The vertical line on a photograph is a static measurement. The vertical that produces the nervous-system change is a dynamic balance, one in which the body's segments are stacked such that motion can pass through them without dissipating into compensatory work. This is why the tenth-hour test of the line — running a wave through the spine from cervical to sacrum — registers whether the dynamic balance has been achieved. If the wave passes uninterrupted, the verticality is the kind that frees the nervous system. If it catches, the verticality is the static kind that orthopedic schools have been measuring all along.
"Holding the head, pulling up on the side of the head, jiggling it, back from the side to side. You can feel the spine as a continuous wave all the way down to the sacrum, so you have more weight on the end of the line with no interference along the spine. That's right. And do you recognize how what he's describing describing there there is is a test of balance. Something isn't out of line. Something isn't catcher. Something is balancing its opposite number. And so you get this uninterrupted wave through the body. Now, actually, that wave occurs in the mesodermic body. The body that has derived from the mesoderm. But the behavior pattern that it instills is in the ectodermic body In the body that has derived from the ectoderm, the nervous system. And it may or may not, it probably will but not predictably, carry through into that endomorphic endodermic body, the gut body, the gland body. How does it carry through to the epidural? I don't know. Several things in life I don't know is one of them. Don't you hear how that question violates what we're preaching in? Don't you hear how you're asking for a specific cause for a specific effect?"
She names the wave-test of the tenth hour and the nervous-system reach of the change.
Why nervous-system work cannot be reached directly
One of Ida's persistent corrections to her students in the 1975 Boulder class was that the verticality work, even though it reaches the nervous system, must not be aimed at the nervous system directly. The nervous system, she pointed out, is not accessible to manipulation in the way myofascial tissue is. The fascia can be reached, repositioned, asked to work. Nerve trunks cannot. The thyroid cannot. The only point of access to the autonomic chain is the position of the bony and soft-tissue structures around it. This is why she insisted on working in the myofascial layer rather than chasing reflex points or chakras or nerve trunks. The verticality of the spine is the point of leverage on the nervous system; everything else is consequence.
"What you see as you look at this, you begin to see how balance is necessary between bodies as well as within bodies. Certainly, you've got to balance muscles in that connective tissue body. And this is where you can start because myofascial units are something you can lay your hands on and with your hands you can affect it with your hands you can put it somewhere and ask it to work. You can't do that with the stuff that derives from the ectodermic body. You can't get ahold of a a nerve trunk and just pull it and yarn and expect to get service out of it. But you can do it with myofascial tissue. Therefore, your myofascial myofascial tissue becomes something that is infinitely valuable to you because you can reach it. You can't just get ahold of the thyroid gland, for instance, and drag it around hither and yon and expect to get service out. But you can get ahold of a lot of myofascial tissue in the neck which controls the nervous innervation to the thyroid and drag it around. This is the basis of all manipulative systems, though not all manipulative systems are aware of what is their strength and what is their weakness."
Ida explains why the nervous system can only be reached through the myofascial layer.
The discipline of this restriction, she argued, is what kept the work honest. Other schools claimed nervous-system effects through other means — pure mental discipline, reflex stimulation, energetic transmission. Ida did not deny that such effects might exist. She insisted only that the practitioner of Structural Integration work within the layer the practitioner could actually touch, and trust that the verticality so produced would do its own work on the structures that could not be touched. In the second-hour discussion with Jan in the 1975 Boulder class, Ida cautioned a student against trying to swing herself into the nervous system directly; the work, she said, must keep itself aware of tension and compression in the myofascial tissue, and the nervous system would follow.
"And some of those old words were pretty good. If you consider that in the joints, have the proprioceptors that have to relate back to the central nervous system. We were doing fifth hours last. Yeah. And I think you people be a lot better off if you don't try to get yourself swinging into the nervous system but do keep yourselves being aware of the differences in tension and compression, if you want to say that, within the myofascial myo no myofascial tissue."
She warns Jan against trying to address the nervous system directly.
The horizontal of balance, and what fails when it fails
In the 1976 Boulder advanced class Ida placed the tenth-hour balance in its broader context: the universe of material structure, she observed, works at its optimum under a law of balance, and the test of a good tenth hour is whether the body has come into that balance. The wave passing uninterrupted from cervical to sacrum is the index. The wave occurs in mesodermic tissue but the behavior pattern it instills is in the ectodermic nervous system — and may or may not, but probably will, carry through into the endodermic gut and gland body. This is the most explicit statement she offered of how far the verticality work reaches and how it carries from one germ layer to another. Even she admitted there were limits to what she could specify.
"got a much greater degree of balance than you had before. Wherever you are going in that material universe, are recognizing the fact that the material stuff in the three-dimensional universe works at its optimal when it is under a law of balance. And this is what your tenth hour is about. Did you hear from any of these people about what is the test for the tenth hour? Supposing some of you take on that one. What is the test for the tenth hour? When do you know you have done a good tenth hour? When you can. The person sitting straight and hung up with the tuberosity. Holding the head, pulling up on the side of the head, jiggling it, back from the side to side."
She describes the balance the tenth hour aims at and the test by which it is verified.
What fails when this balance fails is something Ida discussed with characteristic bluntness in the 1976 advanced class. The bony structures of a body cannot always be brought into a clean vertical. People come with half-vertebrae, with occiputs whose left and right halves are differently shaped because of a lifetime of compensatory carriage. The vertical work cannot undo these. What it can do is balance the soft tissue around the unchangeable structure such that the body moves toward whatever balance is available to it. This is why she rejected the idea that Structural Integration could make crooked structures straight. It moves them toward balance — and balance, not straightness, is what frees the nervous system.
"But I would like, if I could, to throw a monkey wrench into the notion that most of you have, if not all of you, that by the use of structural integration, you can take these cockeyed, crooked structures and make them straight. You can't. There are many reasons why you probably can't. One of the reasons is that the bony structures in that body have spent a lifetime growing into certain patterns. I will never forget my disbelief one time many years ago when I went into an anatomical looking the The Was States. Those various United Occiputs that I was looking looking at at, that the bones didn't match. There was more bone on the right side or the left side, literally more bone than there was on the other side. Because down through the whole lifetime of the fellow whose occiput that was, he had been using his head to balance his imbalances, and his structure had changed in accordance with the demand he put put on on. Do you think you're going in there and in two weeks or three weeks change that phone?
Ida corrects the assumption that the work can make crooked structures straight.
The fifth hour: belly wall, psoas, and the rotation in the pelvis
When Ida taught the fifth hour to the 1976 Boulder advanced class she returned to the question of how a vertical line becomes visible only after the front of the body has been organized. The belly wall falling forward, she observed, almost never falls symmetrically — it sags further down on one side, further around on the other. The asymmetry is the outward sign of an internal rotation in the pelvis. The fifth-hour work, in addressing the abdominal wall and through it the psoas, produces a vertical not because it pushes the body into alignment but because it allows the belly to fall back and the pelvis to settle into the balance available to it. The verticality of the fifth hour is, in this sense, a consequence of resolving a rotation that had displaced the psoas from the line.
"On the inside, it felt like the groin was a place where it was not I didn't feel it traveling through my groin the way I Well, that's a good observation, but I think it's a rather personal one. Yeah. What was my what did I call to your attention? Those being the characteristics of the fifth hour? No. No. That have any relation to a vertical? Very little. Of course, one could say if one wanted to make the story better that that belly trip was really a question of the need for lift. But it didn't look very vertical to me. That falling of the abdomen rarely goes rarely goes symmetrical. It's further down on one side, further around on the other side. Anybody know why? Because when that belly does what it does, it's doing it in response to a rotation within the pelvis. You see how a nice little mechanistic turn of mind can help you along. And so if you can get that belly wall where it belongs, up and back and balanced, lo and behold, you're going to look at that pelvis and say, gee, look. That looks much better. And I am going to say, The six hundred and first time. Now, I'm going slowly, I'm pausing, to give you people time to put images into your mind and look at them and see whether those images conform to what I'm saying or would you argue with what I'm saying?"
Ida walks the class through the rotation-in-the-pelvis logic of the fifth hour.
The fifth-hour example is a useful corrective to any reading of the verticality doctrine as a recipe for symmetry. The vertical line, in Ida's actual teaching, is not a target the practitioner imposes but a condition that emerges once the rotations and compensations of the body have been resolved enough that the segments can stack. The autonomic plexi that lie along the psoas can then function not because they have been addressed but because the rotation that had been compressing them has resolved. The nervous-system effect is, again, a consequence of the structural work rather than its aim.
The eleventh hour and the conversion to function
When Ida discussed the eleventh hour — the first hour of the advanced cycle, when it existed — she described it as the place where the static verticality of the tenth hour begins to convert into something dynamic. The advanced work begins where the basic series ends: with a body that has been brought to a static balance and that now needs to learn to function within that balance. The conversion takes place at the legs. The intrinsic musculature of the leg, working in proper relation to the extrinsic sleeve, is what permits the standing body to operate dynamically rather than just statically. And it is in this conversion, she suggested, that the deepest nervous-system reorganization occurs — because dynamic function recruits proprioceptive and autonomic feedback in ways that static balance does not.
"Even the first day that we started the advanced class. Look at the first day of the elementary class, look at the first day of the advanced class and look at what you are talking about this morning. You see those other two first days. You saw radicality as being so much more important. And as of today, you are beginning to recognize that it isn't verticality. It's no longer the static, it's the dynamic. Now the problems that, the questions that you bring in and that fall into these two groups, you think that the dynamic is further along the static. It's something has to be added to the static before you get the dynamic. And you've been adding to it in these four hours. The first hour, the eleventh hour so to speak, doesn't add very much dynamic. If you notice what you see is the static improvement of the whole body below the waistline. But that is the road, that is the sort of bridge by which you bridge into the dynamic. Once again, it's the legs you see. But you somehow or another have to get this intuitive feeling for the change from static to dynamic. Now you get the beginning of that when you get that tenth hour balance, you know, where you take the head and you feel the relation that there is between the intrinsics of the spine and the extrinsics of the sleeve. But the person is not sufficiently experienced, shall I say, at that time to be able to get ahold of intrinsic musculature and hang onto it, use it, demand from it."
She describes the conversion of static into dynamic verticality in the eleventh hour.
The horizontals reappear at the dynamic level. In the 1976 advanced class Ida noted that the advanced hours bring the practitioner back to the horizontal hinges — but now as functional hinges rather than as alignment markers. The dynamic body has horizontals at the ankles, knees, hips, elbows, and shoulders that act as axes of movement, not as static planes. The nervous-system pattern that uses these hinges is what Hunt had been measuring as the downward shift in motor control. The verticality has become a dynamic verticality, and the nervous system has reorganized to use it.
"This feeling of where that body belongs in space, This feeling of where horizontals are. Yesterday, can you remember what Charlotte looked like as she stood before you for evaluation? She was beautifully stacked but you didn't have the feeling of the various horizontal hinges on which which she you had had to to move. Move. Does this make sense to any of you? Do you know what I'm talking about? But she was beautifully stacked. Mean, if you've been a good artist and you're drawing a picture of Charlotte as she stood there, said, Mine, that's a fine, well balanced woman. But it wasn't a sufficiently dynamic woman. You see, this dynamic element depends on the horizontals. There are other elements that depend on the verticals. And when you get into the advanced hours, you begin to need to see, need to feel really horizontals because it's those horizontals that act as hinges."
She names the dynamic element as the work of the horizontal hinges.
Coda: gravity as the field through which the nervous system operates
The verticality doctrine, taken as a whole, reduces to a single working hypothesis: that the upright animal is an animal whose nervous system has been changed by gravity, and whose nervous system can be changed further by being brought into proper relation to gravity. The mechanism is mediated by the vertebral column and the autonomic chain that runs alongside it; by the major junctions and the hinges that translate vertical line into dynamic function; by the segmentation that makes the upright stance possible at all. Ida did not always articulate the doctrine as a single chain — she taught it in pieces, across rooms, with colleagues filling in different sections. But the pieces fit. The verticality is for the nervous system. The nervous system is what verticality makes possible. The work — when it works — moves a body from one to the other.
"I move so much better. I do so much more work. What have you done to me? And all we can say is we haven't done a thing except to prepare your body so that the field of energy of the earth, the gravitational field, is able to support, work through your body and support it, instead of tearing it down. You probably heard in school that the problem with all human beings is that they are standing and operating on two legs and they were designed to operate on four. But the message of Rolfing is that human beings are not static entities. They are evolving entities, and they are evolving toward a two legged vertical entity, an individual who is working best in the vertical field. And the ROFR can actually And see the ROFR the ROFR brings this about, helps this come about. And the ROFA corrects the situations which has happened to the individual, which has distorted his ability to get himself vertical. That's good. Now let me see if there's anything else that can you think of that we didn't handle. Let me look down here."
Ida summarizes the doctrine to a public interviewer, for distribution to a non-specialist audience.
What Hunt and Silverman added to this picture, and what Ida cited them for, was the empirical and formal vocabulary by which the doctrine could be tested. Hunt's downward shift in motor control and Silverman's elastic-versus-viscous network are not the verticality doctrine itself; they are how the doctrine might be verified at the level of measurement. Ida treated their work as a confirmation rather than as a foundation. The foundation was clinical: the bodies she had worked on for forty years, and the change she had repeatedly seen when verticality was achieved. The science came afterward, and was welcome, but the doctrine did not depend on it.
