The doctrine stated plainly
In her 1974 Healing Arts lecture, Ida set out the position in its most compressed form. The setting was a public talk to an audience of physicians and researchers, and she was working — as she did often in the mid-1970s — to translate the practice into a vocabulary the chemical-medical establishment could hear. The argument moved in three steps: order can be evoked in the body by balancing its myofascial structures around a vertical; that vertical is a real physical line, not a metaphor, registering the alignment of ankle, knee, hip, lumbar body, shoulder, ear; and a body so balanced stops being broken down by gravity and starts being supported by it. The claim is consequential because it inverts what every accepted school of body mechanics taught in the twentieth century. The Harvard group, the physical-education establishment, the orthopedic textbooks — all named verticality as the goal. None, in her reading, had any method for producing it.
"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 lays out the logical chain in her 1974 Healing Arts lecture:
The phrase 'gravity acts supportively' is the hinge. Every other school of body mechanics, Ida observed, taught the measuring stick of verticality without explaining how the body might actually arrive there. Her contribution — the one she insisted distinguished Structural Integration from every neighboring system — was a method that took the plastic medium of the myofascial body and organized it around the gravity line so that the field could pass through. The next step in her argument was the move from static stacking to dynamic balance, and she pressed her advanced students hard on this distinction. A body can be lined up like a stack of blocks and still be losing its fight with gravity, because static verticality is only the entry into the work. The deeper goal is a body that finds its line dynamically, in motion, without effort.
"This is what often has offered in addition to any other school. What's the difference between this and this? Is the answer. We are the only group who recognize that in order for a living body to be at ease in its spatial environment on the earth, it must deal positively with gravity or rather gravity must deal positively with it. Because what we here in Lawton are here to do, we can't change the gravitational field. This is odd, but we just have nothing that means yet. But what we can do is to change the way the parts of the body that I have already referred to, how they fit together into a whole which can transmit the gravitational field. And in its energy, which is the energy of the earth, in its transmitting of that, it enhances its own energy field."
In her 1973 Big Sur advanced class, Ida names what makes the work different from every neighboring school:
Fascia as the organ that keeps you from falling
If gravity is the therapist, the fascial body is the medium through which it works. In a 1974 Healing Arts lecture Ida offered one of her most memorable images for this. She compared the body to an orange whose pulp has been scooped out, leaving only the rind: the rind, in her analogy, is the fascial envelope, and it is what gives the body its shape, supports it, and keeps it from collapsing on itself. The point of the image is that fascia is not a wrapping around muscle but the organ that determines what the body's contour even is. The factory inside — the chemistry, the cells, the digestion — runs because the fascial body holds the architecture within which those processes can occur. This was, for her, terra incognita, a tissue that the medical literature had barely examined. She liked to tell the story of a student she had sent to the library to find out what fascia was: two days later, the student returned empty-handed.
"but fascia is the stuff that keeps it from falling in on itself, falling in on its face, keeps you from falling on your face. It is your fascial body that supports you, relates you"
The fascial body, in Ida's most condensed image:
The orange image continues from there into a fuller argument: that energy added by pressure to the fascia changes the relation of the fascial sheaths, which changes the contour, which changes the way the body sits in the gravitational field. The static balance of the first hours becomes, as the work progresses, a dynamic balance. And the dynamic balance corresponds — Ida insisted — to a psychological and energetic change as well. The ratio of body energy to gravitational energy shifts. The body becomes capable of building up rather than running down. This was the language she used to bridge between mechanics and what she sometimes called the second energy, the energy that did not obey the law of inverse squares. Whether the two were the same energy or different aspects of one she would not say; the data, in 1974, did not let her say. But the structural argument held: the fascial body, organized around the vertical, becomes the medium through which gravity does its work.
"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."
She continues, naming what the change in the fascial body actually accomplishes:
An engineer presses back
Ida's gravitational framing did not go unchallenged in her own classroom. In an Open Universe class in 1974, an engineer in the audience pushed back on the soft-tissue language she habitually used. He had been hearing her talk about the body being held up by tent poles and tent ropes — the fascial sleeves as guy-wires — and as a mechanical engineer he wanted to insist that the force keeping the body upright was compressive, not tensile. His view was that gravity pulls the head down, the head rests on the shoulders, the shoulders rest on the spine, and ultimately the load passes through the bones. Tensile structures hold the bones in their proper relation, but the actual standing-up is done by compression through the skeleton. The exchange is one of the few preserved moments where someone in her own circle articulated a competing mechanical model on tape.
"Yeah, I'd always talks about the body being held up by the soft tissue and talks about tent poles and whatnot and there's certainly, know, certain tent ropes help hold the tent up. But in my view as an engineer, my view of how gravity is pulling on my body is that it's trying to pull it down, trying to pull my head down, my head rests on my shoulders, trying to pull that down, and that eventually there has to be a depressive force to keep me standing up. And the compressive force is this kind of a force and a tensile force is this kind. The only, Probably the only part of my body that can take a compressive force enough to hold me from falling down, gravitational field is my bone structure and I feel that that the gravitational pull on me towards the center of the earth comes down through my bones. You know I feel that it doesn't do it properly unless my unless my tension structure is right. But if my soft tissue, my tension structure that holds my bone structure in the right way, at the very least there's no, I don't need to spend energy to stand up. Biological structures are different from all other structures. I put a bowling ball, set a bowling ball here, it can sit there all night and no work is done in the sense."
An engineer in the 1974 Open Universe class lays out his alternative model:
The disagreement is real but smaller than it first appears. The engineer concedes that the tension structure has to be right for the compression to work — that if the soft tissue is properly arranged, no energy needs to be spent on standing. Ida's claim was always that the soft-tissue arrangement was the operative variable, the thing the practitioner could actually change. The bones are where they are; the fascial investments are plastic. Working with the plastic medium is what shifts the whole structure into a relation with gravity that lets the skeleton do its compressive job without effort. The two models are less in conflict than complementary — and the engineer, by the end of the exchange, seems to grant this. What the moment preserves is Ida's classroom as a working laboratory of competing mechanical intuitions, not a doctrinal monologue.
Posture is what you do with structure
If gravity is the field and fascia is the medium, what then is the difference between posture and structure? Ida treated this distinction as foundational and pressed her advanced students to meditate on it. Posture, she pointed out, comes from a Latin past participle meaning 'placed' — it implies an act of placing, of holding something in position. Structure, by contrast, is relationship. The way the parts of the body relate to each other is structural; what one does to maintain or perform that arrangement is postural. The army's command of shoulders-back-and-chin-in produces posture at the cost of the spine; it does not produce structure. And the moment any practitioner sees someone working to hold a position, the diagnostic conclusion is immediate.
"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."
Ida states the diagnostic principle that follows from the posture-versus-structure distinction:
The argument continues into a fuller pedagogical claim. Posture, in Ida's reading, was what the older schools of body mechanics had been trying to teach all along — and what they had failed to teach. Their measuring stick was correct: ankles, knees, hips, lumbar bodies, shoulders, ears all stacked on a vertical. Their pedagogy was wrong, because they could not get the student's structure into that arrangement. Telling someone to stand straight, she said, was useless if the underlying relationships could not produce straightness without effort. The work she developed in the 1950s and 1960s was, in her own view, the first method that could change the structure so that the posture followed without being maintained. That is the doctrinal payoff of the distinction.
"This is what we offer you that none of the more classical systems of manipulation have ever offered. None of these older systems have ever taken into consideration that you cannot get so called posture except as you have structure. Structure is relationship. It's relationship wherever you use the word structure, you are really talking about a relationship. You talk about this beautiful structure, you are talking about the way the top relates the middle, relates to the floor, the shape of the ground. All of this is implied when I say, I was in a beautiful structure tonight. Structure, wherever you use it, is relationship, and it is particularly relationship of parts in a body. 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."
She unfolds the distinction in fuller form, in the same talk:
The center line and the inner arch
When Ida taught the advanced class in Boulder in 1976, she devoted an entire teaching beat to the question of where, exactly, the center line of the body runs. She had quoted the diary of a dancer — Ruth St. Denis, of that generation — who had written that she could not dance well one night because she could not find her center line. The dancer's intuition, in Ida's reading, was structurally precise: she understood that her job was to organize her body around a vertical, and on some nights the line was simply not findable. The question Ida pressed her students with was where that line had to run. Not on the outside of the body, not on the lateral edges. Through the middle. And here she made a small but consequential anatomical claim that contradicted the standard physical-education teaching of her era.
"Your center line connects down the inside of the leg. Your center line is destroyed as weight goes on to the outer arch."
Ida names where the center line actually runs:
She had her students stand in place, feel where their weight was, and then deliberately shift onto the outer arch — and feel the line disappear. The exercise was experimental, not philosophical. The point was that the center line is not an abstraction the practitioner imposes on the body but a felt arrangement the body either has or does not have, and that the practitioner's first job is to know what it feels like to have it and what it feels like to lose it. The line runs up the inside of the leg, through the inner ankle, the inner knee, into the body. As soon as the weight rolls outward — the common pattern, the pattern that years of misinformed shoe wear and physical-education instruction reinforce — the unity is gone.
"to put the weight back again into the center line. See what you begin to feel as you begin to feel the establishment of that center line. And where it goes as it goes up into the body and what you are aware of in terms of its lacks and what you are aware of in terms of its ability to help you unify yourself. Realize that when you are standing with your weight flowing down on the outer arch, you are destroying the unity within yourself. Now this is what I jumped on yesterday when I came in and somebody was telling me from some book or other, it might even have been a book of my lectures, That weight has to go through the three center toes. It's true. This is the abstraction. But what is the silent level? You're feeling it right now. The silent level is talking to you. The silent level is telling you how you can get to act at one with gravity. One of the ways you can do it is by turning your toes up so as to run that line up through the middle. Certainly the negative way to do it is not to let the weight go down on the outer arch. Now after you got all of this done then it's time to put it into the high order abstraction."
Continuing the same Boulder demonstration, she names the felt experiment and what it teaches:
Gravity acts if it is able to
In her 1975 Boulder advanced class, Ida walked her students through how to explain the doctrine to a skeptical newcomer. The scenario was a student attempting to describe the practice to a hypothetical caller who would never spend three hundred and fifty dollars to get herself 'in line with gravity.' The student had said that the work realigns the body along vertical and horizontal lines within the field of gravity, and that this restructuring makes more efficient use of the body's energy. Ida pressed him: why? What is the missing link? The class fumbled. Gravity acts as a constant force vertical to the plane of the earth. When the body is in line with that field, gravity supports motion through space rather than opposing it. But the student's formulation, Ida said, did not go far enough. The phrase she gave them is the most precise short version of the doctrine.
"Gravity acts supportively Gravity acts if it is able to do so. And our job, as I have told you at least six times in this class, is to get it get our bodies so that they are they can be supported by gravity."
In the 1975 Boulder class, Ida supplies the formulation her student had missed:
The next move in her teaching was to instruct the student in what to say to the skeptical newcomer once the conditional was in place. He could grant the newcomer everything his earlier teachers had told him — that gravity breaks down a body, that the human structure deteriorates under the field, that the textbook account of postural collapse with age is essentially correct. But then he had to make the structural inversion: gravity breaks down a body only if the body is random, only if it does not relate to the vertical. The destructive force and the supportive force are the same force. The variable is the structural arrangement that receives it. This is the line of argument she instructed her practitioners to carry into any conversation about the work, and she gave them three or four sentences to do it.
"And then you can go on to tell the other guy what he has been told by his teachers all down through his academic career. That gravity breaks down a body, but here you diverge from the teacher if the body is random, if the body does not relate to the vertical. Now do you all hear what I have said? I've given you three all of us have given you three or four or five sentences with which you can carry conviction to any man, or you can begin to carry conviction. They cannot quarrel with any one of those sentences."
She continues, giving her students the rhetorical scaffolding for the conversation:
The pelvis as rocking chair
If the conditional 'gravity acts if it is able to' is the doctrine, the practical question becomes: what is the structural change that makes the body able? Across her advanced classes Ida and her colleagues returned repeatedly to one answer — the pelvis. The pelvis is the bowl that contains the weighty structure above it; its relation to the legs determines whether the load above can rest down onto its supports or whether it has to be held up by chronic muscular effort. In a public-tape exchange preserved on RolfA1, one of Ida's senior colleagues described the work as an unpeeling of the onion, with successive local changes producing compensations elsewhere, all subordinated to one central goal: freeing the pelvis to balance the weight above onto its supports below.
"And once we've once we've allowed the pelvis to move in a sort of rocking chair type of movement that permits it to balance the weighty structure above it onto its connections through the leg. Then the body can can assume this normal erect stance where gravity does not pull down."
A senior colleague names the pelvic-balance principle on the RolfA1 public tape:
The rocking-chair image is doing more work than it appears. The pelvis, in this account, is not held in a fixed horizontal arrangement; it is given back the freedom to move in such a way that it can find balance dynamically. The weight above settles onto the legs below because the bowl has the mobility to accept it. Without that mobility, the practitioner is chasing compensations elsewhere — head forward, lumbar hyperextended, dorsals collapsed — and never reaches the structural cause. Ida's late teaching put more and more emphasis on the lumbars and the lumbodorsal hinge precisely because she found that talking only about the pelvis let students forget that the pelvis's freedom depended on what was happening above it.
"What does matter is you understand you have to lift that up off the pelvis to start getting mobility in the pelvis. Uh-huh. The first hour is the beginning of the tenth hour. Okay? Uh-huh. The second hour is a follow-up of the first hour. Uh-huh. It's just the second half of the first hour. Okay? And the third hour is the second half of the second and first hour. It's literally a continuation. I clearly I clearly saw, you know, last summer that continuation process and how and, you know, Dick talked about how, you know, the only reason it was broken into 10, you know, sessions like that was it because the body just couldn't take all that work. Couldn't take it right. But I just sitting on just trying to figure out how the hell she ever figured out that process, and then began to see it. What she did is what most of of us need to do more."
A senior practitioner in the 1975 Boulder advanced class describes the cumulative work of the recipe:
Movement is the essence, not stillness
In her IPR lecture of August 1974 Ida pressed her students hard on a point that her own earlier teaching had partly obscured: the body is not designed to stand around. It is designed to move. The kind of balance she was after was not a static stillness but a dynamic one — the place where antagonistic tendencies cancel and the body becomes momentarily still without effort. Even on the table, she pointed out, the practitioner begins with the body horizontal because the upright human cannot yet manage the gravitational load on the few square inches of the sole of the foot. The whole curriculum is a progression from prone to upright, from horizontal balance to vertical balance, from a body that has to be supported by the table to a body that can stand on the small surface of its ankle and balance there.
"Remember hearing No, also just in terms of design function, the body, the human body pretty obviously is not designed to stand around, it's designed to move. No, you're talking It has a wider apex There is no such thing in a living human body as stillness except as you get it in balance. Only when you get antagonistic parts balancing do you get stillness? And this isn't really stillness, it's balance, you see. You haven't gone to a place where it's still. You've gone to a place where the tendency to move in one direction balances the tendency to move in the other direction. Now the whole story of the human being emphasizes this. The whole story of the human being emphasizes the necessity, emphasizes that movement is the essence of that human being. Why do you suppose you have 200 or 170 pounds of human being standing on those few square inches of the soles of the foot. You have to be in balance and those souls have to act almost as points. This is the whole story of the upright human being. Now you saw how when we started working on people we laid them flat on their back. Why? Because there was not within them the mechanical possibility of balancing on a point at that time. So you took gravity out of the picture as much as you could by laying them flat so that you had at most 10 to 12 inches of gravitational pull. But they're big boys and girls now. And in order for them to stand on top of those square inches of the soles of the feet and to balance on top of the number of those square inches that constitute the ankle, you have got a degree of balance in that body now that permits a vertical line to come up through the ankles, through the knees, through the hips, through the bodies of the lumbars, through the shoulders, through the ears. Have you all got this picture of progression? Because this is the message of the morning. This progression that a human being is getting from a wad of stuff that's slopping all over the place to a form, a precise form, which acts as though it were built around the line."
In her August 1974 IPR lecture, Ida explains why the work begins horizontally and why it must end vertically:
The teaching beat here is that the static vertical of the early hours is a transitional phase. It is what the body learns first because it is the most accessible arrangement, and because the alternative — random, collapsing, fighting the field — is so far from any organized state that the body cannot find dynamic balance directly. The static stacking is the doorway. Once the body knows what it is like to be lined up, even in stillness, it can begin to find that same line in motion. This is the work of the later hours, and it is what Ida's advanced classes increasingly emphasized in the mid-1970s. The eleventh hour, the post-cycle work, was where the dynamic line had to take over from the static one.
"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."
In a 1974 IPR lecture, Ida names the static-to-dynamic transition as the substance of post-cycle work:
Reading the abdomen and the rotational pelvis
In her 1976 Boulder advanced class Ida turned to the question of how the falling body shows itself in the soft tissue of the trunk. She had just spent the previous evening at Aspen telling an audience that gravity is the therapist and that the practitioner's job is to organize the body so gravity can work through it — a logic she had not, by her own admission, ever fully reasoned out in advance but had only rationalized after watching what the bodies showed her. Now, looking at a row of students in front of her, she pressed them on where the vertical line failed in each body. The abdomen's asymmetrical falling, she pointed out, is rarely just a sagging belly. It is the readout of a rotation deeper in the pelvis.
"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."
In her 1976 Boulder advanced class, Ida reads the asymmetrical abdomen as a pelvic rotation:
The teaching beat is that the falling body cannot be read in isolated pieces. A belly that hangs further down on one side than the other is not a belly problem. It is a pelvic-rotation problem expressing itself in the soft tissue above the pelvic bowl. The practitioner who chases the local sign — pushing the abdomen back in, lifting it up — without addressing the rotation beneath has done nothing structural. This is why Ida insisted that the eye be trained to read the whole gravitational pattern. Falling is not collapse; falling is the visible outcome of a body that has rotated and shifted to take loads off injured or unbalanced parts, and the rotations are what the practitioner must address.
Why aren't we talking about a standing body?
The point about movement gets sharpened in an exchange Ida had with her advanced students about why the practitioner studies spinal junctions at all. The questioner had asked why the cervical-thoracic junction is structurally different from the sixth cervical, and Ida used the question to pivot into the broader argument: that the body is designed to transmit movement smoothly through its junctions, and that the practitioner who studies it as a static stacking misses everything important. She made students name out loud that they were not, in fact, working with a standing body. They were working with a body that moved through the world and whose stillness, when it occurred, was the momentary outcome of balanced forces, not the underlying state.
"And this isn't really stillness, it's balance, you see. You haven't gone to a place where it's still. You've gone to a place where the tendency to move in one direction balances the tendency to move in the other direction. Now the whole story of the human being emphasizes this. The whole story of the human being emphasizes the necessity, emphasizes that movement is the essence of that human being. Why do you suppose you have 200 or 170 pounds of human being standing on those few square inches of the soles of the foot. You have to be in balance and those souls have to act almost as points. This is the whole story of the upright human being. Now you saw how when we started working on people we laid them flat on their back. Why? Because there was not within them the mechanical possibility of balancing on a point at that time. So you took gravity out of the picture as much as you could by laying them flat so that you had at most 10 to 12 inches of gravitational pull."
In the same August 1974 IPR lecture, Ida presses the point about stillness and movement:
The doctrine has a clinical consequence. If the body is fundamentally a moving system whose stillness is balance, then the diagnostic eye must learn to read motion, not posture. A person's structural state is visible in how the segments transmit movement through one another — how the shoulder remains a shoulder through a forward reach, how the rib cage absorbs change initiated below, how the pelvis carries the load through the legs in walking. Posture photographs, while useful, capture only the static endpoint. The richer information is in the gait, the reach, the rotation. This is why her advanced students were repeatedly directed away from textbook anatomy and toward the kind of perceptual training that lets the practitioner see structure dynamically.
Energy, frequency, and the resonance condition
By the mid-1970s Ida's colleagues had begun to translate the gravitational doctrine into the vocabulary of physics. The most sustained effort was made by the physiologist whose paper appears on the RolfB3 public tape, where he reframes the body as an ensemble of joints, springs, and dashpots — an interconnected mechanical system whose individual elements have intrinsic frequencies of oscillation. The argument runs that if those frequencies are in wrong phase relationships with each other, their energies collide rather than cooperate, and even a body with good local mobility cannot move efficiently. The work, in this framing, is what brings the system as a whole toward a resonance condition where the energies cooperate rather than interfere.
"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."
On the RolfB3 public tape, an engineer-physiologist reframes the work in the language of resonance:
The resonance framing was an attempt to give scientific scaffolding to what Ida had been claiming intuitively for years. Her own version of the argument, made in the 1974 Healing Arts lecture, ran through the chemistry of collagen rather than the physics of oscillation. Collagen, she pointed out, is a braided protein whose three strands are connected by exchangeable inorganic ions — sometimes hydrogen, sometimes sodium, sometimes calcium. The ratio shifts with age, with stress, with the addition of energy. What the practitioner does with the elbow or the fingers is, in this model, add energy to the collagen bond and shift the ion ratio toward more flexibility, more resilience. The chemistry and the mechanics are two languages for the same change.
"Two factors contribute to this: the first that the body, seemingly a unit, is in fact not a unit but a consolidation of large segments: the head, the thorax, the pelvis, the legs. The relation of these segments can be changed because the connecting myofascial structure is a structure of connective tissue of collagen. This is what that myofascial body is about. And collagen is a unique protein. The collagen molecule is a very large protein and it is a braiding of three strands a special braiding. These three strands are connected by various inorganic hydrogen sometimes, sodium sometimes, calcium sometimes, and undoubtedly other minerals. These minerals are interchangeable within limits. Thus, as the body grows older and stiffer, undoubtedly a larger percentage of calcium and a smaller percentage of sodium are present in these bonds. But by the addition of energy and what is energy? In this come in this context, it can it is the pressure of the fingers or the elbow of the ralpha. This ratio may be varied by the addition of this energy, and the joint or the connective tissue becomes more resilient, more flexible."
In the same 1974 Healing Arts lecture, Ida describes what the energy added by the practitioner actually does at the molecular level:
After the work: less hyperactivity, less effort
What is the measurable consequence of a body that has been brought into balance with the gravitational field? In the 1974 Healing Arts conference, the physiologist Valerie Hunt presented findings from her own EMG and motor-control studies. The pattern she reported was consistent: after the work, there was less co-contraction of agonist and antagonist muscles, more sequential contraction, and a clear reduction in what she called widespread excitation — the use of irrelevant musculature in tasks where it was not needed. People had been writing with their bottoms, she observed; afterward, they wrote with their hands. The energy economy of movement had become specific to the task at hand.
"It is exhausting. Efficiency then with less tension. Another finding: before structural integration, there was what I called widespread excitation, which was unrelated specifically to the particular task at hand. This means, for example, that people write with their bottom, and their bottom gets very tense when they write. And that is not the specific task at hand. After structural integration, the contractions were quite specific to the task. I monitored other areas and found that there was no overflow, that you used those areas of the body that were paramount in accomplishing that particular task, but you did not use all the muscles in the body when these were unnecessary. Again, it constitutes less hyperactivity, less tension, less tension in their muscular system. And it confirms the statement which I've heard Doctor. Rolfe make so many times, and that energy output no longer is random but is specific to the requirement. That is quite readily confirmed. And then one about a global pattern. One of the things that I observed was that the global pattern if you're walking and taking a step, for example, when you step on your leg, you better have a muscle contraction or you're going to fall down. But when you get off of that leg and onto the other leg, you don't have to have a muscle contraction to hold that leg there."
Valerie Hunt, presenting EMG findings at the 1974 Healing Arts conference, describes the measurable change:
Hunt's interpretation went beyond the measurements. She suspected — though she could not prove — that the work shifted the locus of motor control downward, from the cortex toward the midbrain and spinal-cord levels. The cortex, in her account, is what produces fine nuance but also clumsiness; it is where co-contraction tends to live. The midbrain controls the great proximal joints — shoulders, hips, trunk — and produces rhythmic, coordinated movement. A body whose central control had shifted downward would move with the kind of unforced rhythmic quality that Hunt and others observed in well-organized bodies. This was hypothesis, not data, in 1974; but it was the kind of physiological speculation that the gravitational doctrine had begun to invite.
Compensation and the vicious cycle
If the well-organized body distributes load smoothly through balanced segments, the disorganized body does the opposite. In an extended exchange on the RolfA1 public tape, one of Ida's senior colleagues described the process by which local aberrations propagate through a structure. A kid falls off his bicycle. The bruised thigh hurts when the body carries itself in its normal pattern. So the body shifts the pattern — carries the weight differently, alters the relationship of trunk to pelvis — to take the hurt off. The shift would be temporary if the body returned to its previous arrangement once the thigh healed, but it usually does not. The compensation becomes the new structural baseline. Muscles begin to shorten. Movement diminishes. The cycle starts.
"And that in turn creates, for that to happen with the structure, spinal structure, way it's created, necessarily involves a an accentuation of the lower curvature, a an anteriority of the top of the pelvis, and so on. I would like to make more realistic to you what Al is bringing out. Probably some of you don't mean it, but some of you may. For example, the kid falls off his bicycle and it gets pretty badly lashed in the thigh. And so for several days as he walks, this hurts. And it also hurts if he carries his body in a certain pattern. Yeah. If he can his trunk is balanced above there in a certain pattern. And the pattern that may be hurting may be the normal pattern. So he will shift that normal pattern to something that will quote take the hurt off. Now what I'm wanting you to get is the recognition of the fact that this is your feeling appreciation of the situation which Al has been describing verbally. Mhmm. You see, I want you all to have this Yeah. Very vital realizations, this gut realization of what's going on rather than a head realization of what's going on. Okay? Okay. So once the body has assumed this nonnormal these deviations that or aberrations that we're talking about, the effect of this the effect of this on balance is that there is less motility in the region of the unbalance. There there are there's less movement Certain muscles begin to shorten and harden. And as that happens, there's this progression, this vicious cycle is is started progression of tissue towards hardening, towards as there's less movement, less flow of vital fluids into the area, less pumping of nourishment into that area. Muscle"
On the RolfA1 public tape, a senior colleague describes how a local injury becomes a chronic structural pattern:
The doctrine implicit in this account is that no structural pattern is local. Because the gravitational field acts on the whole body, any imbalance at one point produces compensation elsewhere. A head forward of the line requires something in the back to counterweight it, which means an anterior tilt of the pelvis, which means an accentuation of the lumbar curve. The chain runs all the way through. This is why the practitioner cannot work piecewise on isolated complaints. The work has to address the structure as a system in which every part participates in carrying the load. And once the body has assumed its compensated arrangement, the field that should be supporting it instead reinforces the distortion — adding energy to the patterns that need to dissolve rather than to the ones that need to emerge.
Tools, not chemistry
Across her teaching Ida insisted on naming what made the work different from the medical mainstream. The medics, she said, had won the twentieth century by working with chemistry — by synthesizing molecules that operated on the body's chemical systems. Her contribution was to recover the structural school of healing, which had been displaced when chemistry took over around the turn of the century, and to give it a foundation that the older structural schools had lacked: the gravitational field as the organizing reference. Where the chemists used molecules, the practitioner used gravity. Where the chemists changed what flowed inside the body, the practitioner changed what flowed through it.
"But what we can do is to change the way the parts of the body that I have already referred to, how they fit together into a whole which can transmit the gravitational field. And in its energy, which is the energy of the earth, in its transmitting of that, it enhances its own energy field. You can change the body by virtue of the fact that its segments are segments of a whole and then the gravity can flow through. Now this is the basic concept of Rolfe. And tomorrow when I get you all together on the griddle, I'm going to ask you for this answer over and over again in many, many different forms. What does Rolfing contribute to the ideas of the world at the moment that no other schools of? And the answer is that we are using gravity as our tool. So you see, we don't escape to a nice little humble fact sheet. We're just as over proud of ourselves as the medics, but we are using gravity as our field, not chemistry."
In her 1973 Big Sur advanced class, Ida names the distinction sharply:
The framing is more than rhetorical. Ida understood the practice as a contribution to a particular cultural moment in which the chemical model of medicine had reached its dominance and was beginning to show its limits. The structural school, she argued, was overdue for a return, and the gravitational doctrine was what made the return possible. The earlier structural schools — chiropractic, osteopathy, the various manual traditions — had worked with the body's mechanics but had not located their work within the gravitational field. Naming the field as the operative reference is what made her account both new and, in her own assessment, more fundamental than what had come before.
"Be no class tomorrow. What is wrong? Hey. Come on. Come on. Come on. Okay. Give it to us. That's right. And the rougher is somebody who understands how to make those changes. And rauffing is a process I was happy to hear that word process is a process where you prepare the body to be able to accept the gravitational field of the earth for support, for enhancement. See, the random body is such that gravity cannot work through it. The field that surrounds the earth can not work through it. It has to work against it."
In her 1976 advanced class, Ida defines the practice in its most spare form:
Coda: the gravity that nourishes
The most striking move in Ida's late doctrine — and the one most likely to be missed if one reads her too quickly through the mechanical vocabulary — is the claim that gravity, in a body organized to receive it, becomes a nourishing medium. The phrase appears in her 1974 Healing Arts lecture in the immediate context of the collagen-bond argument: when the gravity vertical of the body coincides with the gravity line of the earth, the field of the earth augments the field of the body. The body becomes vitalized. The flesh becomes resilient. Body functions improve. The energy of the earth, she said, contributes to the energy of the body.
"Back to shape in this context means vertical. Vertical to the surface of the earth, vertical like the burrows of the chestnut, vertical like the force of gravity. Because only when the gravity vertical of the body substantially coincides with the gravity line of the earth can that energy field of the earth reinforce and augment the field of the human body. Then the energy of the earth contributes to the energy of the body. The body becomes vitalized. The flesh becomes resilient. Body functions of all sorts improve, for gravity at this point is the nourishing factor. Gravity is the nourishing medium giving to the energy quotient man gravity a higher value, because the man is more energized. This expresses itself in many changes in behavior patterns. Among them, among them is a different state of consciousness."
In her 1974 Healing Arts lecture, Ida names gravity as the nourishing medium:
This is the conceptual destination of the whole doctrine of falling and gravity. The body that falls is the body whose structure cannot receive the field. The body that stands easily, that moves without effort, that finds its line dynamically — that body is being fed by the same force that breaks the random body down. Ida did not claim to know exactly how the energetic exchange worked. She would point to the collagen chemistry, to the resonance arguments her colleagues were developing, to the aura measurements that some of her physiologist allies were attempting, and she would say that the evidence pointed in a direction that mechanics alone could not yet account for. But the structural argument she did claim to know. Gravity is the therapist. The practitioner's job is to prepare the body. And what gravity then does, when it is able, is the work.
"Because you see, in meditating on posture and meditating on structure, you can ask the same questions. You can ask the question of, now see here, if I alter this structure, what can I hope to get from it? Similarly, you can say, if I alter this posture, what can I hope to get from it? This is a big question. And you ask any of your MD friends, and they'll say, oh, Rod, nothing. Ain't so? You change those relations. You change that structure. And you get the kind of ease and the kind of vitality that you have seen some of your friends get who have gone through this system of structural"
Ida closes with the structural promise that follows from the whole argument:
