The Boulder claim: scoliosis as disease-entry through the psoas
The single most explicit statement Ida made on this topic was issued in her 1975 Boulder advanced class, during a discussion of a particular scoliosis case the students had been working on the previous day. The exchange begins with a disagreement: a student feels he reached something in the third hour; Ida disagrees and tells him he did not get nearly what the situation warranted. From that disagreement she pivots to a larger doctrine. The room contained a skeleton on display; she gestured to its mild scoliosis, distinguished it from the deep scoliosis of the woman they had worked on, and then made the claim that has become the central evidence for the topic of this article. She frames it as something the students should not try to argue to physicians but should record privately.
"If that scoliosis is the result of something that happened as a disease process, The entrance of the disease has been through the psoas. Now you can't probably, can't sell that to any of your medical friends, but I strongly suggest that you put it in your own notes because wherever, even in that idiopathic scoliosis that Donna had or in that scoliosis that Norm had yesterday or the one that was right here that Lloyd was working on, those things have come in by a breakdown of the supported process of the psoas on the lumbos."
Ida, in the 1975 Boulder advanced class, after distinguishing a pathological scoliosis from a merely structural one:
The claim is structurally strange and worth slowing down over. Ida is not saying that the psoas causes disease. She is saying something more specific: that when a disease process produces a structural consequence visible in the spine, the route of entry — the place where the body's support architecture first broke down — was the psoas-on-lumbar relationship. The psoas is the structure that holds the lumbar spine together from in front; when its supportive function fails, the lumbars lose their organization, and the scoliosis that follows is the body's accommodation to that prior failure. This is not a theory about etiology in the medical sense. It is a structural reading of where the body first became vulnerable.
Why the psoas: the most important muscle in the body
To understand why disease-entry-through-the-psoas was even an available claim in Ida's thinking, one has to register how much weight she placed on the psoas as a structural unit. In her 1975 Boulder teaching she pressed students to name what made the psoas unique, and she returned again and again to the same answer: there is no other system in the body whose well-being is as consequential as the psoas-rectus combination. In a parallel 1971-72 mystery-tape lecture she made an even larger claim — that the psoas is, in her view, the most important muscle of the body, full stop. These are not throwaway emphases. They establish that when Ida says disease enters through this structure, she is naming the body's structural keystone.
"And more and more, I would like you people, particularly you people who have looked at systems mathematically, to recognize the presence of biological systems operating to do a job. And here you have that system par excellence. There is no other single system in the body that is as important to the well-being of the body as this psoas rectus combination. Why? Noel? It represents a balance between, like, the front of the body and the back of the body, between the Well, when you come right down to a facility, isn't in the back of the body, it's in the middle of the body."
Ida, in her 1975 Boulder advanced class, on what the rectus-psoas system represents:
The 1973 Big Sur class records the same claim in even more compressed form. There she names the psoas as the most important muscle in the body and immediately admits that she has not yet succeeded in making the wonder of its pattern real to her students. She then describes the pattern — the muscle that comes down in front of the spine, that is iron and cathode, something different in kind from the ordinary motor muscles. The language is strained because she is trying to communicate something the standard anatomical idiom does not have words for: that this is not just a flexor of the thigh, this is the structural axis of the body.
"Terms of I still haven't succeeded in getting into your mind what I think is the wonder of the difference of pattern of this muscle it comes down in front of the spine it was iron and cathode, something of that sort, something that is not nasal to its extent. That we begin to get into it. Now what else can pull the leg Okay, now is this, to what extent do you feel that this is clear and that this has clarified the This is a working class where we try to get from reality into abstraction but back again from abstraction to the event, to the world. Now this is an extremely important concept for you to play with."
Ida, in the 1973 Big Sur advanced class, attempting to convey the structural singularity of the psoas:
The deterioration sequence: glued, shortened, jamming the lumbars
The mechanism by which the psoas becomes a route of disease-entry is not mystical. Ida describes a specific physical sequence — observable to the practitioner's fingers, predictable in its course — by which the psoas deteriorates and pulls the lumbar architecture down with it. The sequence begins with disuse. The psoas stops being recruited in walking, in breathing, in the everyday work of the body. When that recruitment fails, the muscle does not simply weaken. It glues itself to the front of the lumbar spine, it shortens, and in shortening it folds the vertebrae together. In a 1971-72 lecture Ida walks her students through this sequence in their fingertips, asking them to visualize what a deteriorated psoas actually does to the spine in front of which it lies.
"What happens when a psoas is out of condition and out of commission? And the answer is it gets glued to the front of the lumbar spine and it shortens. As it deteriorates, it shortens. And in shortening, it's going to pull some of those vertebrae folds and it's going to jam all of those vertebrae together. So the first place you go is the lumbar spine. Will you get that lumbar spine really viable. Making a lumbar spine out. Making it something that just isn't a piece of connecting wood then you see you begin getting a different level of physiological operation in that And if you've got a different level of physiological physiological operation in that psoas, you're going to have a different level of physiological operation in all those lower pixies. You've got to get it in the lumbar."
Ida, in a 1971-72 mystery-tape class, asking the students to visualize into their fingertips what a deteriorated psoas does to the lumbars:
Note what this sequence implies for the disease question. If a disease process — polio, an idiopathic systemic insult, the chronic stress of a bad marriage as she elsewhere acknowledges — strikes a body whose psoas is already glued and shortened, the lumbars have no structural ally. They jam further. The scoliosis that emerges is not the disease's direct work but the body's accommodation to a support system that was already failing before the insult arrived. The psoas was the gate that did not hold. This is what Ida means by entry: the structural location where the body's resistance to deformation was already compromised, and where the disease therefore registered first.
"Making it something that just isn't a piece of connecting wood then you see you begin getting a different level of physiological operation in that And if you've got a different level of physiological physiological operation in that psoas, you're going to have a different level of physiological operation in all those lower pixies. You've got to get it in the lumbar. You will unquestionably get it in the solar plexus, which doesn't lie in the psoas on it, but is close enough, neighboring enough, that anything that happens in the psoas is going to have a reflection there. Anything that happens in the psoas, anything that happens to the core of the diaphragm has to reflect."
Continuing in the same 1971-72 lecture, on what happens once the psoas is restored:
The lumbar plexus on the surface of the psoas
The reason the psoas can serve as a route of disease distribution — not merely as a passive structural support that fails — is anatomical. The lumbar plexus, the autonomic relay station for the entire lower body, lies practically embedded on the surface of the psoas. In her RolfB4 public tape Ida walks through this explicitly: the psoas is unique not only as a motor muscle but as the structure whose intimate anatomical contact with the autonomic nervous system means that any failure in the psoas registers immediately in the autonomic field. This is the missing link between her structural and her physiological claims. Disease is not arriving at an inert mechanical support; it is arriving at the meeting place of structure and innervation.
"And I'm telling you, telling you question mark, that these things are agonist and antagonist. Yes. I am, and you'll see it. Now the psoas, as I've said, is unique in many respects. In the first place, it does have a motor function. But in the second place, it has a different quality about it than the the motor muscle. Because it is so intimately connected with the autonomic nervous system, because the lumbar plexus is practically embedded on the surface of the psoas. And therefore, anything that exercises the psoas, that gives that pumping function"
Ida, in her RolfB4 public tape, on what makes the psoas qualitatively different from ordinary motor muscles:
The autonomic intimacy explains a clinical pattern Ida had observed long before she had a theory to account for it. In a deeply revealing passage from the same public tape, she remembers the early days of her practice and the surprise that many heart conditions did not respond to her work until she reached the fourth and fifth hours — when she got into what she then took to be the rectus, but now believes was actually the psoas. The recognition came late, but its implication was decisive: the structural address for cardiovascular and visceral conditions was deeper than she had initially supposed, and it was the psoas, with its plexus and its diaphragmatic neighbor, that held the keys.
"So along about the time that you get your polar your psoas pulled up, you've also got your diaphragm pulled up. I remember in the old days when I was developing this, and I wasn't developing it from a developed philosophy, but from the actual practical experience. How amazed I used to be that many heart conditions didn't respond until you got into the fourth and fifth hour when you got down there, I thought, to the attachment of the rectus. I didn't understand this. But now what I say is that I wasn't dealing with the rectus at all. I was dealing with the psoas, including the psoas with the diaphragm and the psoas. And the whole rhythm of the heart control there coming through there. What did you say that to me?"
Ida, in her RolfB4 public tape, reconstructing what she now believes she was actually treating in the early years:
The diaphragm-psoas link and the routes of distribution
If the lumbar plexus is one half of the anatomical reason the psoas is a disease-relevant structure, the diaphragm is the other half. The psoas attaches on the anterior aspect of the first, second, and third lumbar vertebrae; the crura of the diaphragm attach immediately adjacent to it on the anterior surface of the first and second lumbars. They are neighbors, structurally fused in their attachments, and in practice, when one becomes aberrated, the boundary between them collapses. Ida's students in 1975 Boulder pressed her on whether the crural fascia could remain separate from the psoas fascia in a deteriorated body, and she conceded that in theory yes, in practice the structures become one. This is why disease in the psoas territory is not contained to the psoas territory.
"It seems to me that the psoas anatomically, I don't know, I haven't dissected the psoas diaphragm area of a cadaver but it seems to me that the psoas must get tied up to that diaphragm because the curve of the diaphragm come down to those Yeah. Those are actually in theory at least there's some space between the crura and the psoas. In theory. Yeah. But in practice, as you know, when things get aberrated, they move around and they get random and they get Yeah. Anyway, see the psoas work freeing the diaphragm. I I see that happening as people are are worked. And on the psoas, they're they're breathing freeze. They get more movement in that diaphragm and the costal arch and so forth from work on the psoas. And it's important, I think, working at the psoas to also not only get it in the lower part of the abdomen but also in the upper part near its its origin."
A student in the 1975 Boulder class raises the diaphragm-psoas question; Ida confirms the practical collapse of the theoretical boundary:
Once the diaphragm-psoas link is recognized, the cascade Ida describes becomes legible. A failing psoas pulls the lumbars forward, jams the diaphragm's attachments, restricts the breathing, compromises the autonomic relay at the lumbar plexus, and through the diaphragm affects the solar plexus and the cardiac rhythm. This is what she means by saying that anything that happens in the psoas reflects through these neighboring structures. Disease arriving at this hinge — whether through chronic structural stress, surgical scarring of the abdominal wall, or a frank pathological process like polio — does not stay local. It distributes itself along the anatomical channels that converge at the psoas's territory.
"And that's the recognition of the fact that the psoas is the motor link, connecting link, between the legs and the diaphragm, the rib cage. So in other words, it's the thing that holds these, the top and the bottom together. Remember that the psoas attaches on the anterior aspect of the first, the second, third lumbars. And the crura of the diaphragm lies immediately adjacent to it on the anterior surface of the first and the second lumbars. So along about the time that you get your polar your psoas pulled up, you've also got your diaphragm pulled up."
Ida, in her RolfB4 public tape, naming the psoas as the connecting motor link between the legs, the diaphragm, and the rib cage:
Surgical scarring and the older generation
One concrete form of disease-entry Ida named explicitly in her RolfB4 public tape is the abdominal scar — the surgical history that her own generation, she observed, carried so universally that almost no body of a certain age was free of it. The scar prevents the falling back of the abdominal wall; the abdominal wall's failure to fall back prevents the psoas from coming into its proper relation with the rectus; the resulting imbalance is permanent, in the sense that the structural compromise will not resolve without specific intervention. Surgical entry into the abdomen is, in this reading, literally an entry — a disease-related event whose structural signature is recorded in the impaired psoas-rectus mechanism for the rest of the patient's life.
"here and right now, you begin to see where from whence comes all the bay windows. From whence comes all the and another irremediable cause of bay windows, of course, is the amount of surgery that has been done. Fortunately, this younger generation is no longer getting it, but my generation. We just didn't find these people without seeing a nice big star across that abdomen, which now prevented the and permanently prevented the falling back of the abdominal wall. And you see all this gives you a picture of what has what begins to go wrong with the individual as he gets into the thirties and the forties and the fifties and, well, the sixties."
Ida, in her RolfB4 public tape, on the surgical legacy of her own generation:
The surgical example is useful because it grounds the disease-entry doctrine in something less controversial than the scoliosis claim. No one would dispute that an abdominal surgery leaves a permanent structural mark; the question is whether that mark functions as Ida describes — by interrupting the psoas-rectus reciprocal relationship and thereby disabling the structural axis. Her teaching, here and elsewhere, is that the answer is yes: a scar across the abdomen is not just a cosmetic event, it is a structural lesion that permanently displaces the psoas from its proper role in the body's vertical organization.
Half the population: deficient psoas function as baseline
Ida did not present the deteriorated psoas as a rare clinical finding. She presented it as the baseline condition of the population she was working on. In one of the RolfB6 public-tape passages she estimates that half the people her students will encounter have deficient psoas function and therefore deficient psoas structure — they cannot reach it, they cannot control it, and the consequence is that the psoas-diaphragm relationship is off in roughly half the bodies the practitioner will see. This is the population context in which the disease-entry claim should be read. The psoas was, in Ida's reading, already compromised in most of the bodies she worked on; disease arriving at such bodies arrived at an already-failed structural gate.
"And so you begin to be freeing that very key muscle of psoas, and enough of you have been looking around and enough people under enough circumstances and at enough times to have seen the ways in which this thing varies, the ways in which half the people that you know, I suspect, have deficient function of the psoas and therefore structure of the psoas. They are not able to reach that psoas. They are not able to control that psoas. And if they can't if they don't have the appropriate balancing function of the psoas, the psoas diaphragm thing is going to be off. How can it be otherwise?"
Ida, in the RolfB6 public tape, on the baseline rate of psoas deficiency in the population:
In the 1975 Boulder class she pressed the point even more bluntly: in practically everybody, the psoas is not working. The framing is not hyperbole. It is a statement about what athletic training, dance training, sedentary office work, and the ordinary stresses of an American life do to the structure that ought to be most active. The rectus abdominis takes over the work of flexion; the rectus femoris takes over what should be psoas activity at the groin. The psoas, displaced from its role, deteriorates by disuse. By the time disease arrives — whatever form it takes — the gate is already not holding.
"Well, man, look at the fact that in practically everybody, the psoas is not working. Did I see someone else? Yeah. I was just gonna say that's the key to a horizontal pelvis, it seems like. It's the key to the horizontal pelvis and we equally, the horizontal pelvis is the key to the effective interplay, interaction of psoas and rectus. Now in practically all the all the random bodies that you will come to, particularly in the random bodies of males or of females who've made something of a fetish of athletics or dancing or something of the sort. That psoas is just stuck as it crosses the cubes. And how can you get into play? There's no stretch to it."
Ida, with David and Steve responding, in the 1975 Boulder advanced class:
Why disease enters here rather than elsewhere
The disease-entry doctrine becomes legible once the four claims of the preceding sections are stacked together. First: the psoas is the structural axis of the body, the single most consequential muscular unit. Second: it deteriorates by a specific mechanical sequence — gluing, shortening, jamming the lumbars. Third: it sits at the anatomical convergence of the lumbar plexus and the diaphragm crura, so its failures distribute themselves through both the autonomic system and the breathing apparatus. Fourth: it is already compromised in roughly half the population at baseline. Disease arriving at such a structure does not simply pass through; it registers, and its structural registration is the visible scoliosis, the bay window, the cardiac dysfunction that Ida saw responding only when she reached the fifth hour.
"And until you get some resilience in that so and, you can't get your love to do that. Now is this picture clear? You realize that heretofore, comparatively, we have been talking about lifeless dreams when we talked about the muscles of the leg. Compared with the life and the change and the vitality and the importance the vital importance never independent of the record. Now there's another reason why that psoas has such a vital importance. Because it doesn't make any difference what kind of exercise Americans take. Is dependent on those plexi suffer. And this"
Ida, in a 1971-72 mystery-tape class, on why the psoas has such vital importance:
Note also what Ida is not claiming. She is not claiming the psoas causes disease. She is not claiming that the medical model is wrong about etiology, and she is explicit that her students should not try to argue this position to physicians. What she is claiming is a structural principle: in a body whose psoas is functioning, disease has somewhere else to register first. In a body whose psoas is failing — which is most bodies — the failed structure offers the path of least resistance, and the disease takes that path. This is consistent with her broader framework, which treats structural integration not as therapy in the medical sense but as a reorganization of the substrate on which therapy operates.
"I don't know which one that's gonna be either. In a rough body, as you walk, the flexion bringing the leg forward should be in the psoas. In an unrulved body, the flexion is in the recti. The flexion is distributed between the rectus abdominis and the rectus femoris. Now this is the reason why when you go and you look at skiers, for example, they have these enormous thighs. Many of our dancers have. Do you remember? Thighs out of all proportion to their body size. And you see, they started their dancing or they started their skiing or they started their water skiing, of Takashi."
Ida, in the 1975 Boulder advanced class, on the rectus-femoris substitution that produces the structural displacement:
The medical literature, the iliopsoas, and Ida's reservations
Ida was aware that there was a parallel discourse on the psoas in chiropractic and osteopathic literature. In a 1971-72 lecture she discussed a book titled The Iliopsoas, the Undiscovered Key to Back Structural Anomalies — a text whose author, Arthur McFarland (or as she sometimes misnamed him, the man up in Martinez), argued that spinal curvatures could be reduced by balancing the psoas. Ida's position on this literature was complicated. On one hand, she acknowledged that someone in the chiropractic world had at least named the psoas as the key structure. On the other hand, she was sharp about the limits of treating the psoas as a discrete muscle to be adjusted rather than as the axis of a reciprocal system.
"Well, there's this cast His name's. No. Fell by the name of Manel. Oh, Cheryl. Arthur McFarland. That's the guy you mentioned yesterday in the morning. He's just written a book on the iliopsoas and which I I have a Listen. Stay away from those books on have them in. Speaking of the iliopsoas muscle, when I was taking my audition class, I think the brains are in the pubococcius muscle and when in doubt say psoas. But Well, I really I really mean what I say. You get to know so damn much about that iliopsoas that you don't know anything about a body. Yeah. Although he talks about reducing spinal curvatures by balancing the psoas. Well, all right. A great many chiropractors have done the same thing, and there's a whole school of chiropractic, for instance, that sells the idea that you can straighten the spine as well as the spinal cord."
Ida, in a 1971-72 mystery-tape class, on the books that have been written about the iliopsoas:
The reservation matters for the disease-entry claim. If the psoas were merely a muscle to be adjusted — as the chiropractic literature treated it — then disease-entry would be a metaphorical claim about a particular muscle's vulnerability. Because Ida treats the psoas as the axis of a reciprocal system involving the rectus, the diaphragm, the lumbar plexus, the floor of the pelvis, and the lumbar spine, disease-entry-through-the-psoas becomes a claim about a system: the failure point of the body's structural keystone is also the failure point of the systems it organizes. The disease enters at the keystone because that is where the architecture first gives way.
"And that's some of interesting things, like one of the things for instance he shows, the kind of thing I'm interested in, is that if you, when you have the pelvis in a tipped alignment, that the forces acting through the psoas sometimes accumulate to more than a ton. And there's something on the order of 23 to 2,500 pounds of force exerted by the psoas. It's no little muscle. I mean it's a huge, mighty mover if you get it into an aberrated I don't remember that."
Ida and a student, in a 1971-72 class, on the mechanical force the psoas exerts on the spine:
Walking, the agonist puzzle, and the limits of the standard idiom
In a 1971-72 mystery-tape class Ida engaged a question her students had been carrying for some time: whether the psoas should be classified as a flexor or extensor of the spine, and how its action ought to be described during walking. She found the question more revealing in what it could not settle than in any answer it produced. The agonist-antagonist idiom of standard kinesiology — one muscle shortens, another lengthens — was the framework her students had been trained in, and Ida considered it inadequate for a structure whose origin lies high on the lumbars, whose belly dives across the pelvic rim, and whose insertion is on the lesser trochanter of the femur. The geometry alone made the standard idiom strain.
"Now the notion of arguments to non arguments is a very arbitrary thing. It has been a very useful notion in unthreading the activities of the muscular body, that it doesn't have to apply to everything. And then certainly if it applies to everything it's not going to apply to them simply. You take for instance this notion of the psoas. Where does the psoas originate? Way up on the lumbars, up beside the second lumbar. Then it comes down back along the second lumbar and then it takes a dive across the pelvis. How are you going to have it back for an agonizing or ordinary sense of something shortens and something happens? You see, it's a much more kind, it's getting into a much more complicated situation."
Ida, in a 1971-72 mystery-tape class, on why the standard agonist-antagonist idiom does not capture the psoas:
The methodological reservation has implications for the disease-entry claim. If the standard idiom cannot describe how the psoas behaves in ordinary walking, it is unlikely to describe how it behaves under pathological stress. The disease-entry claim is, in part, a claim about the inadequacy of the available language: Ida tells her students they will not be able to argue this to their medical friends not because the medical friends are obtuse but because the structural reading cannot be translated into the etiological vocabulary medicine uses. The translation problem is built into the structure of the muscle itself.
The fifth hour as structural address
If the psoas is the structural gate through which disease enters, then the fifth hour of the ten-session series is the address at which the gate is approached. Ida is explicit about this across multiple advanced classes: the fifth hour is where the practitioner finally gets into the psoas itself, after the first four hours have prepared the body to allow that entry. The earlier hours have softened the superficial fascia, organized the legs, established a sense of horizontality at the pelvic floor, and — through work on the rectus — created the antagonist relationship that the psoas needs in order to come into balance. By the fifth, the structure is finally available.
"But you are now getting getting into a different level of operation in that body because the rectus is the antagonist of the psoas. And this is a something which nobody seems to have a fact which nobody seems to have ever put to work consistently. Now the psoas is not is is a relatively unique structure in the body. Listen to what I've said. I've said that the is the antagonist of the psoas, and this is seems to be a piece of just plain nonsense. When did you ever hear of an antagonist lying right next door to its agonist? And yet this is the way the thing works. As they cross the rim of the pelvis, the psoas is practically contiguous with the rectus. And I'm telling you, telling you question mark, that these things are agonist and antagonist. I am, and you'll see it."
Ida, in her RolfB4 public tape, on the discovery that organizing the rectus is the way into the psoas:
The clinical implication for the disease-entry doctrine is that the fifth hour is where the gate is structurally reopened. A psoas that has been the entry point for disease — glued, shortened, contributing to scoliosis or to a cardiovascular pattern — is the psoas that the fifth hour finally reaches. Ida's claim that many heart conditions had not responded until she reached the fourth and fifth hours is the experiential confirmation of this. The recipe's logic and the disease doctrine are the same logic seen from two angles: the recipe is what you do because the psoas is the gate; the disease doctrine is the diagnostic consequence of recognizing that the gate is the gate.
"So that you have to organize this at this level so that the psoas is going to give you what you need to take on and up and get relate it to the diaphragm. And in the fifth hour, you got to doing this, and you got to doing it in terms of the recti in order again to get to the psoas. Shall we arrange a ceasefire? I think that needs another session. I think that needs another session. And you see, in order to change the psoas, in order to change the psoas, you have to change the antagonist of of the the psoas. I don't know which one is the agonist and which one is the antagonist."
Ida, in the RolfB6 public tape, on the necessity of working through the antagonist to reach the psoas:
The unfamiliar lengthening: a psoas that does not shorten when it acts
One of the strangest claims Ida made about the psoas — and one that bears on the disease question — is that in an organized body, the psoas does not shorten when it flexes. It lengthens. It falls back. This is anatomically counterintuitive and Ida acknowledged that her students could not see it in themselves and could not believe it when she described it. But the claim is structurally consequential: a deteriorated psoas can only try to shorten, and trying to shorten when stuck is precisely the deterioration mechanism that pulls the lumbars forward. A healthy psoas, by contrast, gets longer as the joint flexes — falls back into the body, makes room for the diaphragm above and the pelvic floor below, and behaves as the elastic axis it is supposed to be.
"As those muscles get more and more sophisticated, more and more ordered, more and more related, more and more roughed, They lengthen, they don't shorten when they flex. Now this is something that you people are going to have to think about for many hours before it becomes realistic to me. Doctor."
Ida, in her August 1974 IPR lecture, on the lengthening behavior of an organized psoas:
The lengthening claim, taken together with the deterioration sequence, gives the disease-entry doctrine its full mechanical picture. A healthy psoas falls back, lengthens, makes space, distributes load. A deteriorated psoas glues itself, shortens, jams the lumbars, compresses the lumbar plexus, fuses with the diaphragm crura, and propagates dysfunction into every system that converges on its territory. Disease arriving at a body in the second condition does not need to overcome a working structure; the structure is already collapsed. This is what Ida means when she says the entrance of the disease has been through the psoas. She means: the architecture had already given way at that hinge before the disease arrived.
The structural reading of fascia, gluing, and stuckness
The disease-entry claim becomes still more concrete when one attends to Ida's description of how the psoas's deterioration is, at the cellular and fascial level, a gluing event. In her Open Universe lectures and in the IPR lectures of 1974 she describes the substrate of stuckness in fascial terms: a fluid substance that has hardened and not been reabsorbed, often the residue of injury or sickness. The hardening prevents the layers of fascia from moving on each other; the immobilization propagates; the body distributes the stress, and the psoas — as the deepest, most central structural axis — is where the accumulated stress lodges most consequentially.
"You know, all I know is what I experienced and that is that oftentimes there's a warming, like a melting feeling that the place that was stuck or the place that wasn't moving, all of a sudden it gets warm and starts moving. That's my point. You're moving something. They get stuck partially by hardening or there's a fluid substance that seems like that has been hardened and isn't reabsorbed in the flesh. Time of injury, time of sickness. And it seems like whatever it is that is that stuckness between the layers of the fascia is what's reabsorbed at the time when our pressure is or energy is is placed on the body. And I don't know what further to say except that that's the way I feel what's going on. And, of course, the development of that stress pattern or of those places that are immobilized and hardened, we think is primarily related to the way the body deals with gravity because gravity is the most constant environmental force for the human body. And so it's in response to gravity that the body avoids pain, you might say, or avoids the buildup of stress in an individual point by trying to distribute it."
A Rolf practitioner, in a 1974 Open Universe class with Ida present, on the fascial residue of injury and sickness:
Read alongside the disease-entry passage, this fascial description fills in the bridge between event and structure. A disease process — polio, a systemic insult, surgical entry, chronic stress — does its work in the tissues. Some of that work resolves; some of it leaves residue. The residue that lodges along the psoas's fascial planes is the structural memory of the disease, and the consequent shortening, gluing, and jamming of the lumbars is the visible architectural consequence. The disease entered, and its entry is recorded in fascia. The scoliosis that the medical eye sees is the surface reading of a depth-residue at the psoas.
"There's a lot of learning that goes on in the Rolfing session about body movement and especially the experience of proper movement while, as Valerie said, the field of the rolfer is present and the movement that he elicits and so on. And in addition to that, we do have structural patterning which continues that work of eliciting and applying that in daily life. That one day I was talking with a woman who iced cakes, And you can imagine the movement. She iced these great big cakes all day long. Well, that's a determinant in her life. And if she was going to continue that, she would have to make some kind of application to the balanced system so that she could do that in a balanced way as Roffer's doing doing this work."
A Rolf practitioner explaining structural patterning in the 1974 Open Universe class, on how lifework deforms the body and how structural integration responds:
The pelvic floor, the coccyx, and the lower territories
The disease-entry doctrine implicates not only the psoas itself but the territories anchored to it below — the floor of the pelvis, the coccygeal attachments, the obturator fascia, the network of ligaments that organize the basin in which the psoas terminates. In a 1971-72 mystery-tape class Ida traced the fascial continuity from the gluteal wrap of the coccyx through the sacrotuberous ligament up into the psoas fascia, making clear that to release the pelvic floor is to release something that bears directly on what the psoas can do. Disease-entry at the psoas is therefore not contained to the lumbar address. It extends downward into a pelvic architecture that must also be approached if the gate is to come back into working order.
"Shows these ligamentous attachments from the pubes and from the ramus to the sacrum and spinal cord. You can just see how releasing down here will have to affect the sacrum, will have to affect the coccyx and will also, through the obturator internus fascia, will have to affect the psoas fascia going up. Well you see when that coccyx is still pulled forward, the sacrum will be on the strain no matter what. Releasing the sacrum won't release the coccyx as much as releasing the coccyx will release the sacrum, at least as I see it. Yes, Jen? When you study the fascia of the floor of the pelvis, One thing that becomes evident is that the gluteal fascia wraps the coccyx. It's right up to the sacrum. Sacral tuberous ligament, you see that?"
Ida, in a 1971-72 mystery-tape class, on the fascial continuity from coccyx to psoas:
The pelvic-floor anchorage explains a clinical pattern Ida returned to repeatedly: that a coccyx pulled forward keeps the sacrum on strain regardless of what one does at the lumbars, and that releasing the coccyx releases the sacrum more than releasing the sacrum releases the coccyx. The downward attachment, in other words, governs the upward structure more than the reverse. For the disease-entry doctrine this means that restoring the psoas gate is a multi-address operation. The fifth-hour entry from the front is necessary but not sufficient; the sixth-hour work on the rotators and the sacral attachments completes the structural circuit through which the gate can finally come into balance.
Coda: what the disease-entry doctrine commits the practitioner to
Ida's caveat in the Boulder passage — that her students should not try to argue this to their medical friends — is not a retreat. It is a precise location of where the claim sits. The disease-entry doctrine is a structural reading, and the medical model is an etiological one; the two languages do not quite meet. What the doctrine commits the practitioner to is something less than a medical claim and something more than a metaphor. It commits her to noticing, in any body that arrives with a structural consequence of a disease process, that the consequence has registered at the psoas. It commits her to working that hinge — through the rectus, through the diaphragm, through the floor of the pelvis, through the adductors and the rotators — because the hinge is where the architecture both failed and can be restored.
What the doctrine does not commit her to is hubris about cure. Ida is consistent across the transcripts that she does not claim to be a therapist; gravity is the therapist, and the work prepares the body for gravity to do its work. The disease-entry-through-the-psoas claim, read in that frame, is a claim about preparation: the work at the psoas is the work of restoring the gate so that the body's own organization can resume. Disease arrived at a failed gate; the practitioner's task is to make the gate available again, and what happens after that is not the practitioner's to claim. The psoas is named here as the address — not as the cure, but as the place at which the architecture must be approached if the body is to recover the structural condition that disease found wanting.
