What makes a curve primary
In her 1976 advanced class, Ida opens a discussion of spinal curvature with a Socratic move. She refuses to let her students take the curves of the spine for granted as design features. She wants them to name why the spine cannot be straight, why it has the particular shape it has, and which curve is the one the others must accommodate. The exchange that follows is characteristic of her late-career teaching: she pushes the students until one of them gives the answer she is waiting for, which is that the secondary curves exist as compensations for the primary one. The primary curve is the dorsal curve, and it is primary not because it appeared first in evolutionary time or because Ida ranks it as more important, but because it is the curve that the other curves must work around.
"It comes from the fact that the ribs are attached to the vertebra and they can't do anything else but form a curve."
Pressing the 1976 advanced class for the structural origin of the curve, Ida lands the mechanism in one sentence.
Notice what Ida is doing here pedagogically. The students initially want to give philosophical or functional answers — the curve is there for shock absorption, the curve is there for upright posture, the curve is the design. Ida rejects each in turn, not because they are wrong but because they are teleological. She is teaching the students to look at the structure as it actually is and ask what made it that shape. The answer she wants is anatomical: the ribs and the vertebrae are physically connected, the ribs form a firm basket, and that basket constrains what the thoracic spine can do. The curve is the consequence.
"It's got to be an appropriate compensation so that the primary curve can sit there supported. It's got to be. So that the secondary curve is secondary because where it is, where it has to be is determined by that primary curve. That's what makes it secondary."
Continuing the same exchange, Ida names what makes a curve secondary.
The growth pattern that fixes the dorsal
In her early-1970s mystery tapes — recordings that capture her teaching from 1971-72, before the recipe was finally codified for publication — Ida gives a fuller version of the doctrine, locating the dorsal curve's primacy in the growth pattern of the embryonic spine. The thoracic vertebrae, because they are tied to the ribs from very early in development, cannot reorganize themselves the way the cervical and lumbar vertebrae can. The ribs lock the relationship in. The consequence, which she will press into her students again and again, is that the dorsal curve is the curve the practitioner cannot fundamentally change. She can affect it — any hand placed on the back affects it slightly — but she cannot reshape it. What she can do is reshape the lumbar and cervical curves that balance it.
"spine, the so called primary curve is the dorsal curve. Why is that a primary curve? It's a primary curve because in its growth pattern, the vertebra being connected with the ribs and the firmness process of the ribs being such that they sit so that there can't be too much change. This is inherent in the growth pattern."
In a 1971-72 class, Ida explains the developmental logic of the primary curve.
The phrase that matters here is "inherent in the growth pattern." Ida is not making a claim about adult anatomy alone. She is saying that the rib-vertebra system establishes itself early, that the curve emerges as the embryo grows, and that by the time you encounter the body as an adult practitioner, this region of the spine has been fixed in its essential shape for decades. The lumbars and the cervicals retain plasticity. The dorsals do not, or do so only slightly. This asymmetry of changeability — fixed in the middle, plastic at the ends — is what shapes her clinical strategy.
"But you see, as soon as you begin to affect slightly the curve of the dorsals as you do right the minute you begin to put your hands on there, you are necessarily affecting the curve of the lumbar. Because you cannot change one vertebra. It's impossible."
Continuing in the same 1971-72 session, Ida draws the clinical consequence.
Coupling: why the lumbar talks to the cervical
If the dorsal curve is the fixed term in the equation, then the lumbar and cervical curves are the variable terms — and Ida's striking claim is that they are not two independent variables but two ends of one stick. In her RolfB1 public tape, drawn from her advanced teaching, she lays out a relationship that she says the anatomy and physiology books name without ever really explaining: that the cervical curve talks about the lumbar curve, and the lumbar curve talks about the cervical curve. If a practitioner aims to change one without the other, the change will not hold. The two secondary curves are reciprocal because they are both compensations for the same primary.
"You have taken the pelvis and made it as horizontal as you can, but you still have a problem in that body in that you have not changed the cervical organization. Now those of you who have worked with manipulative methods before know that you do not get that the cervical curve and the lumbar curve, these secondary curves are related. That your cervical curve talks about your lumbar curve, that your lumbar curve talks about your cervical curve. Therefore, if you aim to change the one or the other permanently, you have to change the twin, the two ends of the stick. The anatomy books, the physiology books talk about these curves being secondary curves, but I have yet to see any anatomy book or physiology book really discussing the necessity of balance between the cervical and the lumbar. But this is so and this is obvious to you as you start working with bodies."
From the RolfB1 public tape, mid-first-hour teaching.
The mechanism behind this coupling is the dorsal curve itself. Because the thoracic spine is locked into the rib basket, it cannot adjust to absorb imbalances. Anything that goes wrong in the lumbar geometry must be compensated above the diaphragm somewhere, and the only place above the diaphragm that can adjust is the cervical region. So the cervical curve mirrors the lumbar curve, and a practitioner who lengthens the lumbar without addressing the cervical will produce a body that simply reorganizes the imbalance back into itself. This is why every hour of the recipe, in Ida's teaching, ends with attention to the cervical spine.
"curve, that your lumbar curve talks about your cervical curve. Therefore, if you aim to change the one or the other permanently, you have to change the twin, the two ends of the stick. The anatomy books, the physiology books talk about these curves being secondary curves, but I have yet to see any anatomy book or physiology book really discussing the necessity of balance between the cervical and the lumbar. But this is so and this is obvious to you as you start working with bodies. So here in order to complete the work of a generalized reorganization of that body you now have to go up to the cervical spine. Remembering that you are doing once over lightly in that first hour, you are dealing primarily with superficial fashion."
Continuing in the RolfB1 first-hour teaching.
The lumbar is where the spine gives
If the dorsal curve cannot give, then somewhere the spine must give, and Ida's teaching locates that somewhere precisely: the lumbar curve. Returning to the 1971-72 mystery tapes, she develops this as a positive claim — that it is structurally appropriate, even necessary, that the lumbar region be the part of the spine that adjusts to changing structural demands. The lumbar vertebrae, the biggest and most weight-bearing in the body, are also the most adjustable. They are where the spine accommodates whatever the rest of the body is doing. This is a doctrine about both anatomy and pathology: a lumbar that has gone forward in lordosis is not in itself pathology, it is the structural response of an adjustable region to demands placed on it.
"At least that's where I stand. And inasmus and in emphacimus, you never get them, without you get a very distorted rib cage. You see, right from the beginning, you have to let's see how we can put it. The lumbar curve is the point which structurally can give and structurally it does give and structurally it has given. Mostly it goes forward, sometimes it goes back. Sometimes you get a posterior curve. Now, Fox is talking from the point of view of the spine. If we ever get to be great big boys and girls that sit in the Council of the Mighty's, it will be because we do not use that entry, but because we use an entry which is more acceptable to modern thinking."
Continuing the 1971-72 discussion of curves and pathology.
What is striking in this passage is the implicit teleology Ida usually refuses. She has said earlier that she will not preach the spine's design as a strength feature. But here she comes close to it: the lumbar gives because something has to give, and the dorsal cannot. Were the dorsal vertebrae able to slide on each other, she says, the cardiovascular mechanism in the chest would be perpetually disturbed by every fall and movement. The rigidity of the dorsal protects the heart and lungs; the plasticity of the lumbar protects the dorsal. The asymmetry is a system.
"And this story that I have just told you about the fact that the lumbar lever is going to be the one that can adjust, is going to be the one that has to adjust to the structural demands of any body, It has, something has to give and it can give. The dossiers can't give. If the dossiers could give and gave, you would have everybody so that one vertebra can slide back and forth on the other, it would put so much strain on that whole cardiovascular mechanism. Every time you fell it's really a most important point. It's the most important point as to why it is what we have works. And Mr. Indian has said, You start seeing the lumbar change in the first hour if you are trained to see it that way and he is. And this is a very important thing that he has told you this morning."
Same 1971-72 session, moments later.
Reading the lumbar after the first hour
The clinical signature of all this — the dorsal as primary, the lumbar as the place the spine gives, the curves as coupled — is something Ida insists practitioners learn to see at the end of the first hour. A trained observer, she says, will recognize that the lumbar lordosis has already begun to change before any direct lumbar work has been done. The change comes through the dorsal: by softening the superficial fascia over the rib cage and the back, by addressing the cervical and the pelvic ends of the system, the practitioner has already begun to alter the geometry that determines what the lumbar curve has to be. The student in the 1971-72 transcript almost misses this and Ida corrects him.
"It began to be there as I felt I was seeing it at the end of the first hour, even before you got the lower leg in place. Of course it was. Then you see work through Why did it begin in the first hour? I believe it was largely through the work in the hip, getting the action across the rotators. Well, this wasn't the answer that I wanted to hear And the reason I'm putting stress on this answer is that most of these people here don't recognize it. I mentioned it once since we've been meeting, but some of you might not have heard of them. I mentioned to you the fact that in the course of the building of the spine, the so called primary curve is the dorsal curve. Why is that a primary curve?"
Earlier in the same 1971-72 session, Ida walks a student through what the first hour does to the lumbar.
The pedagogical point here matters as much as the anatomical one. Ida is teaching her students to read structure, and what she wants them to see is that an apparent change in the lumbar is actually a registration of change upstream and downstream — in the dorsal envelope, in the cervical balance, in the pelvic position. Pathology in this framework is not a separate category from structure. The lumbar that flattens in discogenic disease is, structurally speaking, a lumbar that has been forced into a compensation it cannot maintain. Put the structure where physiology can function, she tells the class, and the pathology often retreats with the structural change.
"Yeah, because of the last few pastoral I was living for lumbar lordosis. Well the thing that brought to mind was how many times I have seen myself right in discogenic pathology, a person with true pathology, decreased lumbar lordosis, a flattening effect in lumbar spine. Yeah. In conjunction with pathology. Yeah, you see it in here in conjunction with that structure rather than pathological structure. Then you see how to what extent it changes. Pathology is not pathology. It's a provision of physiology. And you get the structure put where the physiology can function, you can change it very quickly by simply changing structure."
Continuing the same exchange.
The spine as a beam, not a column
Ida's framing of the dorsal curve as primary is part of a larger structural argument she developed across her teaching: that the spine is not a column supporting weight from above but a beam — an elongated structure that lies along a surface. In her RolfA2 public tape, she presses this point in a deliberately counterintuitive way. The students assume that if a body is laid prone, gravity will help straighten the spine. She tells them no. Laying the body prone makes the existing anterior displacement worse. The spine should be supine, where gravity pulls the structures into position. The dorsal curve, with its forward convexity, is part of why this matters: a body face down accentuates the curve's natural anteriority rather than relieving it.
"That's what the osteopaths do. That's not what you do. But I would like you to look at this a little more theoretical framework and recognize that what you call a spinal column is not a spinal column at all. A column is something which is supporting a weight on top, which is not the function of the spine as I've frequently told you. The spine is a beam that has been upended. And as such it should lie where beams lie along a surface and the spine should lie along the dorsal surface. And in the random body, as I said to you before, spine is some part of the spine is always anterior, necessarily so. And you can depend on the aid of gravity by putting it supine, laying him on his back and gravity will pull the thing where it should go. And the first law of Ralph, as we've said facetiously, but the thing is not facetious at all, is to get it where it should go and make it move. And this is the fundamental basis on which this operates."
From the RolfA2 public tape, on the position of the body during work.
The beam metaphor reorganizes how a practitioner thinks about the dorsal curve. If the spine were a column, the dorsal vertebrae would be carrying weight stacked above them, and the curve would be a compromise of their load-bearing function. But if the spine is a beam — supported by the soft tissue envelope around it, hung within a fascial bag — then the dorsal curve is part of the beam's natural shape, and the practitioner's task is to position the beam where it can rest. This is consistent with the tensegrity questions Bob and Roger were raising in the same Boulder class: if the spine is not bearing weight in the way a column does, then the curves are not compromises, they are features.
"We have to remove the skeleton here. See, I don't what I can show you. See, one of the big questions that I've been trying to wrestle with, and Roger and I have been talking about this at length, which is what if the spine is a tensegrity structure, then what exactly is the functional part of the spine? What is it that holds the weight? Now when you look at a vertebra, you look at that big round disc shaped creature with the disc on top of it. Think, that's got to be the part of it which is maintaining the weight. But if you look at it more closely, see that in front of that, the body of the vertebra are the spinous processes or behind it, which are triangular shaped. They're like this. There's another triangle, another process coming out in this direction. And also Practically what you've got to hang on there. Oh, here we go. See, there is that triangular shape to it."
Bob, in the 1975 Boulder advanced class, develops the tensegrity question with Ida present.
The dorsal as the line up the back
If the spine is a beam, then the question becomes where the beam should lie. In the same RolfA2 passage, Ida names the answer with a clarity that practitioners can carry into their hands: the spine should lie along the dorsal surface of the body. In the random body, parts of the spine — particularly the lumbar and cervical with their lordoses, and the dorsal with its kyphosis displaced forward — are always too anterior. The work, in some fundamental sense, is to move the spine back to the dorsal surface where it belongs. The dorsal curve, being primary, sets the reference point. Everything else aligns to it.
"A column is something which is supporting a weight on top, which is not the function of the spine as I've frequently told you. The spine is a beam that has been upended. And as such it should lie where beams lie along a surface and the spine should lie along the dorsal surface. And in the random body, as I said to you before, spine is some part of the spine is always anterior, necessarily so. And you can depend on the aid of gravity by putting it supine, laying him on his back and gravity will pull the thing where it should go. And the first law of Ralph, as we've said facetiously, but the thing is not facetious at all, is to get it where it should go and make it move. And this is the fundamental basis on which this operates."
Continuing the same RolfA2 teaching.
There is a deep consistency between this image and the doctrine of the dorsal curve as primary. The dorsal vertebrae, anchored to the ribs, are already in the most posterior position the spine can hold. They define where the back of the body is. Bringing the cervical and lumbar regions back toward the dorsal surface means bringing them back toward the line the dorsal vertebrae are already establishing. The practitioner's work, in this image, is to extend the dorsal's posterior anchoring upward into the cervical region and downward into the lumbar region — letting the secondary curves accept the geometry the primary curve is already declaring.
The lumbodorsal junction
If the dorsal curve is primary and the lumbar curve is where the spine gives, then the junction between them — the lumbodorsal hinge — becomes the most important single structural region in the body. Ida says this directly in her August 1974 IPR lecture. The lumbodorsal junction is where two anatomically distinct configurations meet: the thoracic vertebrae with their spinous processes oriented one way and the lumbar vertebrae with theirs oriented practically horizontally. The two regions have different functions, different geometries, different relations to the surrounding structures. The junction between them is where the body's vertical line is established — or fails to be.
"A rib cage has no relation whatsoever anatomically, spatially, yes, but anatomically. With the lumbar vertebra, as I said to you yesterday, as I called to your attention yesterday, the lumbar vertebra are vertebra which are practically horizontal and the spine of the vertebra extends virtually horizontally back from the body of the vertebra. But in a thoracic vertebra you have a vertebra that goes this way. And there has 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."
From her August 5, 1974 IPR lecture, on the geometry of the junctions.
Ida's claim that the lumbodorsal junction is the most important and the last to be established in processing is a doctrine she returns to repeatedly. It depends on the dorsal-curve framework. Because the dorsal is fixed, the lumbodorsal junction is where the fixity meets the plasticity, where the unchangeable meets the adjustable. Any practitioner who tries to organize the body without finally bringing the lumbar and dorsal regions into balance at this junction will produce a body that holds a partial integration but not a full one. And — as one of her senior students discovers experientially in the same lecture — this junction is also the first to go when anything else fails.
"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. And it's coming. But you see, what I'm trying to say to you is that those five different major junctions of the body can be organised into a unified whole differently, with different speeds, different amounts of attention, different understandings, different efforts. Each one is an independent personality of its own. And in terms of establishing a vertical line around which the man can be built, the lumbo dossal is the most important and is of necessity the last to be established. Now the lumbodorsal, in its final ultimate analysis is a balance, is a different type of balance. Got any light on that?"
Same August 1974 lecture, naming the lumbodorsal as the most important junction.
What this means for the practitioner is that the lumbodorsal cannot be addressed as a single point of intervention. It registers the state of the entire body. A trained student in the same lecture observes that on a day when he is not feeling well, the lumbodorsal is the first place where extension fails. Ida agrees emphatically. Sore throat, stomach ache, headache, foot trouble — any of these will destroy the lumbodorsal junction's organization. The junction is the body's barometer because it is where the primary curve and the most-adjusted curve come together, and any disturbance in the whole system shows up there first.
"And it doesn't make a darn bit of difference what goes wrong with you. You can have a sore throat. You can have a stomachache. You can have your tail end in trouble. You can have a vile headache. Any and all of these will destroy that lumbar dorsal junction. Sometimes you can keep some of those other lesser junctions going under these adverse circumstances. But never can you keep that lumbodilosal junction going. Now this is a very interesting thing. And it's also significant in the sense that, as far as I know, there is again no other animal for whom a lumbodorsal junction is an important position place in my anatomical situation. It's just like that thing on the top of the head. There is no other animal except man with whom you look down straight on the top of the head and you don't see the face. There is no other animal except man where that lumbodorsal hinge has this urgently important message."
Continuing the same lecture, Ida confirms a student's observation about the lumbodorsal.
How the rhomboids and psoas establish the line
Ida's claim that the lumbodorsal is the key junction is not a mystical claim. She wants her students to be able to name the anatomy that makes it work. In the same 1974 lecture she presses them: what are the actual mechanics that establish the lumbodorsal junction? The students offer the breathing diaphragm; she accepts it as one. They offer the rhomboids and the psoas; she names this as the heart of the matter. These two muscle groups operate on opposite sides of the spine — the rhomboids on the dorsal side, the psoas on the anterior side. No other major junction in the body has this front-and-back symmetry of operators. This is what makes the lumbodorsal singular.
"I see two, There seem to be two major livers operating here. That's right. They're opposite sides of the spine. Rhomboids and that structures between the scapula and then there's the psoas coming up this way. That is what I'm bringing out and you see the thing that's unique about this is that one of those groups is on one side of the spine, the rhomboids are on the back of the spine and the psoas is in the front of the spine. This is a unique junction, no other junction is like this. Both also relate to girdles. Yeah, it relates to girdles but after all of a sudden you can't have your girdles just flapping around in the grooves."
Same lecture, working out the muscular mechanics of the junction.
The structural logic here is consistent with the dorsal-curve doctrine. Because the thoracic vertebrae are anchored to the ribs and the ribs are anchored to the sternum, the dorsal side of the lumbodorsal is set up by the work that organizes the rib cage and brings the scapulae into relation with the spine. The anterior side is set up by the psoas, which connects the anterior surface of the lumbar vertebrae down through the pelvis to the femur. Both sides have to be organized for the junction to come into balance. The practitioner cannot establish the line at the lumbodorsal by pressing on the back alone.
"So it is forming this sheath then which is enclosing the erector spinae which is made up of the three bundles of muscles in this region. However, there's a difference in the arrangement between the twelfth rib and the iliac crest. We have one of my famous drawings here which this is now about think L3 which is just a nice easy level to take in terms of lack of complication but we can carry it then in either direction. We have then, if this is the spine of the vertebra, this is the transverse process and this is the centrum so it's upside down. This mass of muscle which I've drawn in here is representing the erector seating. That heavy bunch of muscles lying then between in the space between the spine of the vertebra and the transverse process. Just below the transverse process and extending out from it at this point then would be the quadratus lumborum. And filling in the space then the remaining space between the transverse process and the centrum is the psoas. Now, we have then the covering, the lomo dorsal fascia covering the erector spinae with of course a superficial fatty fascia over it."
In the same August 1974 lecture, Asher details the fascial architecture at the lumbodorsal.
Lengthening the back without flattening the curves
A naïve reading of Ida's teaching might be that she wants the spine straight — the curves abolished, the body brought to a flat vertical. She does not. The curves are part of what the body has to be. What she wants is the curves shallower and the spine longer. In the second hour, working on the erector spinae, the goal is not to eliminate the dorsal kyphosis or the lumbar lordosis but to lengthen the back so that the curves can be more gentle and the spine as a whole more extended. This is the work of bringing the secondary curves into a more balanced compensation around the unchangeable primary curve. The third hour follows and extends this work.
"You better get that back lengthened. Because as we said yesterday, the thing that you are doing in every hour of brothing that you do is lengthening that body, thinning it for the most part and lengthening it. And in order to lengthen it, you have got to get greater length in those spiny erectors. Now who in this room doesn't have a picture in his mind of those spiny erectors? Who needs to see it in the anatomy books? You all know what I'm talking about. You all know those pictures with those three strands going up. Now in the old, old days, when there weren't as many people who had seen the demonstrations of Rolfing, It used to be quite incredible to people to see that the shortening of the body comes in by virtue of the spreading apart of those spiny erectors and the lengthening of the body can be produced by the tightening together of those spiny erectors. Now everyone in this room, in the course of his second hours, has seen this, but it used to be nothing short of a revelation. You see how when you brought those two strands together, all of a sudden, you had length in the body. And you see this is telling you something else."
From the 1975 Boulder advanced class, on lengthening the spiny erectors.
What this means in practice is that the practitioner's intervention on the dorsal region is not on the curve itself but on the soft tissue that holds the shortening. The spiny erectors run along the dorsal surface; bringing them in toward the midline produces length; the dorsal curve becomes shallower not because the practitioner has straightened the vertebrae but because the soft tissue envelope has been organized to support the spine in a longer, more posteriorly-positioned configuration. The dorsal curve remains the dorsal curve. It is just less exaggerated, and the rest of the spine has more room to balance around it.
"And this work on the back, the intent is to reestablish that fetal secret in the back to enable the spine to go back in that primary It seems to me that in order to go and establish proper primary and secondary curve in the back, we'll have to start someplace. Now I think a straight back would not be, you know, it seems you can't go and and put the whole thing straight. Mhmm. I think the best alternative is to go back to the the curve it has originally Okay. Stop right there because there are people, as a matter of fact, there are people in other fields right in this town that will argue that quantity about how the spine is supposed to be. The person I'm thinking of would say to you that the back really should have no curves at all. That it should be straight and is really working on that model."
From the 1976 advanced class, a student tries to articulate the goal of the curves and Ida intervenes.
The cervical mirror
The other secondary curve — the cervical — is where the body's compensation for the dorsal becomes visible in the head and neck. Because the cervical lordosis is reciprocal to the lumbar lordosis, and because the dorsal is fixed between them, the cervical curve registers what is happening at the other end of the spine. A head carried too far anterior is, in this framework, a head whose cervical curve has accommodated a lumbar problem the body cannot otherwise resolve. The seventh hour, in Ida's recipe, takes this on directly. But practitioners can also see the cervical curve change in earlier hours, before any direct cervical work, because the curves are coupled.
"Why don't you discuss a little bit the structural relationship between the head and neck or head and thorax across the neck and see how that develops into answering your question. Well, let's see. What we're trying to do is to get the head, the occiput back with respect to the cervical vertebrae. I guess just in practical terms what I'm measuring there is lordosis of the cervical vertebra. Now you're measuring the lack of relationship to the gravity. So you're looking a cervical curve instead of again the mass in the field. Then you're going to get down like nearsighted."
From the 1975 Boulder advanced class, seventh-hour teaching.
The cervical work in the seventh hour is also where the dorsal-curve doctrine has one of its sharper consequences. Ida tells her students that the scalene muscles attach down to the second rib, which means that if the rib cage is seriously distorted — if the dorsal envelope has not been adequately reorganized in the earlier hours — the practitioner cannot get the scalenes back where they need to be. The first and second ribs, which give fundamental support for the neck, depend on the dorsal organization that the first six hours have addressed. The cervical curve cannot be fully resolved if the dorsal envelope below it has not been prepared. This is the same coupling, viewed from above.
"Now this gives you a new complication because it says that if the rib cage is seriously distorted, you are not going to be able to get those stilenoid back. If the first and second and third rib are dragging, you're not going to be able to get those skelini back. So in other words, as you look at that shoulder and head of an individual, it behooves you to look critically as to whether ribcage is below it in such a fashion that it's giving support. Because it is your first and second ribs and their position which is going to give you a fundamental support for that neck. Now if you've got a bad rib situation, even as far down as the fourth or fifth, which Al has, you're not going to be able to get your first and second up. And once again, this is a circular situation. But whether it's circular or whether it's linear, there's only one thing to do and that's to start with the neck and get it as far back as you can. Because only by getting that neck as far back as you can can you free the normal movement that should be present in the atlas and the axis?"
From the 1971-72 mystery tapes, in seventh-hour teaching.
Why the chest comes first
If the dorsal curve is primary, the question naturally arises of why Ida's recipe begins with work on the chest. In the 1975 Boulder advanced class, a senior student works through this question explicitly, trying to back himself into Ida's perspective on why the recipe evolved as it did. The chest, he concludes, is where the practitioner can deliver the most experience of structural integration in a single hour. By freeing the breathing and beginning the work on the pelvis from the front, the first hour gives the client a felt experience of what the work is. But the chest is also, in the dorsal-curve framework, the rib cage — the structure that locks the primary curve in place — and softening its envelope is where any structural reorganization has to begin.
"First time Ida put her hands on me, she went right there. And so I started thinking about the logic of the sequence and how it evolved, you know, and trying to back myself up to Ida's perspective, you know, and see what she saw. You know, why did the recipe evolve this way? And I think one of the things is that by working and this is a level of abstraction above the physical body, but I think it's relevant that by working on the chest and the pelvis, you deliver the most experience of what we're trying to do. So that when someone gets a first hour, you're establishing in their cells what it is that Rolfing's about. You know, before you put their hands on them, they've only got ideas, abstractions. And in the first hour you're giving them an experiential look at what goes on. And you get the most done for the least amount of doing by freeing the breathing and the pelvis. You know, so there's a lot of impact in that first session. You know, you've taught them at a level that they can understand what Rolfing is, and that says more than all your word."
In the 1975 Boulder class, Bob works out the logic of why the recipe begins with the chest.
Bob also recounts a piece of Ida's history that illuminates the same point. When she was traveling and trying to teach chiropractors, who were used to quick snapping releases, she would deliberately demonstrate by changing one side of a chest and leaving the other untouched, producing a visible asymmetry that the chiropractors could not dismiss. The trick worked because the rib cage is what registers the dorsal envelope's organization. Change one side of the chest and the dorsal spine on that side responds. The chest is not a peripheral structure to be addressed for breathing's sake. It is the dorsal curve's external surface.
"And I think while all this showy stuff was going on, I decided that she had to really she had to blow them out. How can I really with all these tricks that I have in my back, how am I gonna blow these guys out? She said, well, if I can make this I'll just do my little change one side of the chest and leave the other side so small that it's fairly obvious that the body's going like this, you know, one side. And and that and we'll just see how they like that trick. You know? And and everybody went, well, that's pretty good. Show me that one again. But the problem started off."
Bob continues with a historical anecdote about Ida's demonstration strategy.
The spine as a unit, not a stack of bones
Ida's larger structural argument — that the dorsal curve is primary, that the curves are coupled, that the spine is a beam — depends on a view of the spinal column that she insists is different from the chiropractic and osteopathic view. The chiropractor sees a series of bones to be manipulated. Ida sees a unified mechanism. The whole spine is a single structural unit, and the curves are properties of the unit, not of individual vertebrae. This is the framing that makes the dorsal-as-primary claim coherent: the dorsal curve is primary not because each thoracic vertebra is individually special but because the rib-bound thoracic assembly is a single mechanical unit that the rest of the spine has to accommodate.
"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."
From her August 1974 IPR lecture, on the spine as a unified structure.
The unified-spine view also reframes what manipulation can accomplish. If the spine is a stack of bones, manipulation is a matter of pushing each bone toward where it should go. If the spine is a unit, manipulation works on the envelope — the fascia, the muscles, the soft tissue continuity — that holds the unit in its current shape. This is consistent with everything Ida has said about the dorsal curve. The practitioner does not work on the dorsal vertebrae directly. She works on the rib cage, on the chest, on the back, on the lumbodorsal fascia — the envelope that lets the dorsal unit sit where it does. The curve responds to the envelope.
The lumbar as the spine's tent pole
In her RolfA3 teaching, Ida returns to the lumbar from a different angle. Having worked the quadratus and freed the twelfth rib in the third hour, the practitioner has begun to elevate the rib cage off the pelvis. The trunk lengthens because the spine straightens. And the spine straightening means, in her vocabulary here, that the lumbar can now function as a tent pole — a vertical structural element that holds the rest of the spine in proper relation. This is the operative consequence of the dorsal-curve doctrine: the practitioner cannot make the dorsal a tent pole, because the dorsal is curved and rib-bound, but she can make the lumbar a tent pole, because the lumbar is the adjustable region designed to take vertical organization.
"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. 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."
From RolfA3, third-hour teaching, with Fritz collaborating.
There is something striking in Ida's pairing of structural and autonomic concerns here. The lumbar vertebrae, when properly positioned, are not just bearing weight more efficiently — they are letting the autonomic nervous system, which runs along the front of the vertebral bodies, function without compression. This is the reverse side of the dorsal-curve doctrine: the dorsal vertebrae, locked into the rib cage, protect the central organs from the strain of constant adjustment. The lumbar vertebrae, designed to adjust, become problematic when their adjustment becomes excessive — when the lordosis is too deep, the autonomic chain in front of them is compressed too. Structure and physiology, again, are not separate categories.
"It is in accordance with the logic of situation that you begin to organize the cervical spine and get that cervical spine lengthening which in terms of the cervical spine also means going back. And so you suddenly find that what you have really been doing is straightening that spine from one end to the other. The guy stands up says, why I feel so much straighter. Of course, he feels straighter. He is straighter. He made him that way. He made himself that way. Because all the way along the line, you have been demanding from him the kind of movement which as you held the muscle and the fascia organized, he organized himself. But what you have to know is how to hold it, where to put it, what commands to give him to get him to do it. Now the Lord has been very, very good to me this summer. Both of the classes this summer have listened and learned and said, now just let your pale turn under. It has taken me almost twenty years of teaching before I got a class that would do that. Because they will all say, now turn your tail under. That's right. Now lift."
From the RolfB2 public tape, on the cervical and lumbar as reciprocal functions in the pelvic-lift work.
Posture and the dorsal: what the army gets wrong
Ida's account of how bodies go wrong includes a critique of what she calls the standard American posture training — the shoulders-back, chest-out posture that the army imposes on young men. In a 1976 advanced class she draws this critique out. When you put your shoulders back and your chest out, what actually happens to the dorsal spine? It goes forward. The shoulders-back command, intended to produce an upright look, drives the dorsal vertebrae anterior, deepening the kyphosis-displaced-forward problem that her doctrine of the beam-along-the-dorsal-surface is designed to address. The army's posture, in her framing, is a posture organized around appearance rather than around the actual mechanics of the spine.
"To have been through the routine by which we as Americans train our young men, partly in high school through games, etc, but still more through their period of service in the Army. Shoulders back. Glut in. What happens when you put your shoulders back? Come on, where are the advanced ropals? Are they all asleep still? Chest do, sir. Yeah, what else? Dorsal spine goes you can't talk too good. Spine goes forward, you can't talk too good. The spine goes forward. That is the big key there. The spine goes forward."
From a 1976 advanced class, Ida pushes the students to name what happens to the dorsal spine in shoulders-back posture.
This critique is not casual. It is the dorsal-curve doctrine applied to cultural posture norms. If the spine should lie along the dorsal surface — if the beam should rest against the back — then any posture that drives the spine anterior, whatever its cultural prestige, is structurally wrong. The army's posture and the dance teacher's posture and the corset's posture all share this defect. Ida's posture, by contrast, asks the dorsal vertebrae to rest as far posterior as the rib basket will allow, and asks the lumbar and cervical regions to find their compensating shallow curves around that resting position. The aesthetic of the result is different from the army's because the structure is different.
"And it's much easier to go back to the old posture which gave rise to it than it is to keep it in your head that you are changing it to the new posture that keeps itself in. And you have the possibility of the salvation months sometimes and sometimes years before you have the willingness, the energetic, Otherwise I'm just yelling at you. But you see there is only one way to get into that new position of vertical spine relatively and two horizontal girdles. And that's for the spine to go on up through it."
From the 1971-72 mystery tapes, on the only way into the new posture.
Coda: the curves as one system
Ida's teaching about the dorsal curve, gathered across the transcripts of 1971-76, presents a coherent structural argument. The dorsal is primary because the ribs make it so. The lumbar and cervical are secondary because they exist as compensations for the dorsal. The curves are coupled because they share the unchangeable middle term. The lumbar is where the spine gives, because something must give and the dorsal cannot. The lumbodorsal junction is the most important single hinge in the body because it is where the fixed meets the plastic. The spine is a beam, not a column, and it should lie along the dorsal surface where beams lie. None of this is presented in her teaching as separable doctrine. It is one structural picture, and the practitioner's work on the body proceeds within 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. She just sat and watched bodies."
Bob, in the 1975 Boulder advanced class, articulates how the recipe hours connect.
What the practitioner inherits from this body of teaching is not a set of techniques but a way of seeing the spine. When she puts her hands on a back, she is not addressing individual vertebrae or individual muscles. She is addressing the dorsal envelope that holds the primary curve, the lumbodorsal junction that registers the whole body's organization, the cervical curve that mirrors the lumbar, the rib cage that locks the thoracic assembly. The dorsal curve, in this seeing, is the structural fact around which the body's organization revolves. It is the constraint that makes the practitioner's work both possible — because something has to be fixed, for the rest to find its compensation — and bounded, because the curve itself cannot be changed, only its envelope can be reorganized so that the curve becomes less burdensome to the body that has to live with it.
