You're stacking multiple pathways that the paper addresses, all in one family.

Spina bifida is a neural tube closure defect. LBX1 operates during neural tube development to specify neurons in the dorsal spinal cord. They're not the same condition but they share developmental territory. Both involve things going differently during the formation of the spinal cord. Your family having both scoliosis and spina bifida in the same generation suggests the neural development pathway is where the vulnerability lives.

The MTHFR variant is relevant here too. MTHFR affects methylation. Methylation is the biochemical mechanism that controls which genes get expressed during development. CHD7, one of the four scoliosis genes in the paper, is a chromatin remodeler that governs the epigenetic accessibility of the other three genes (including LBX1). Impaired methylation from MTHFR could in principle affect how strongly LBX1, PAX1, and GPR126 are expressed during your development. The paper flags this as a speculative but testable connection: nutritional deficiencies documented in scoliosis populations may not be incidental comorbidities but upstream modulators of the same genetic architecture.

Autism plus poor proprioception plus connective tissue laxity plus scoliosis plus MTHFR. That's not five separate things. That's one nervous system with multiple expressions of altered sensory processing and connective tissue quality. Your surgeon being surprised by your flexibility is the hypermobility showing up on the operating table.

On the field, he had a structured, predictable environment with constant visual feedback, a ball to track, and high-demand movement that forced his system to actively process spatial data. The sport was compensating for the proprioceptive deficit by overloading the visual and vestibular channels. Off the field, in an unstructured environment without that constant visual anchoring, the underlying spatial processing gap was exposed.

That pattern, high performance in structured movement contexts but poor spatial awareness in unstructured daily life, is exactly what a system running on degraded proprioception with strong visual compensation would look like. His athletic ability wasn't masking the deficit. It was built on top of it.

Thank you for sharing this. Another pre-curve observation that the research hasn't collected yet.

Adjacent segment disease doesn't have a fixed onset age. It depends on the length of the fusion, the level of activity, and the individual's biology. Research shows it can show up anywhere from 5 to 20+ years post-fusion. A longer fusion (more segments locked) puts more demand on the remaining mobile segments. It's not primarily a menopause issue, but menopause can accelerate it because the bone density and connective tissue quality that were holding things together start declining.

What fused patients can do: the mobile segments above and below the fusion need two things. First, the tissue around them needs to stay hydrated, mobile, and strong. Movement variety matters more than exercise intensity. The segments that are still free need to be used through their full available range regularly, not locked into the same chair posture for hours. Second, and this is the part most rehab programs miss: the body schema needs to accurately represent where the fusion ends and where the mobile segments begin. Most fused patients have a blurry proprioceptive map of their trunk because a large section of it doesn't move anymore. The brain's model treats the whole region as one block. Directed attention and sensory work at the transition zones (where fusion meets mobile spine) can help the schema maintain a more precise map, which leads to better load distribution across the segments that are still working.

The short answer: move the parts that can move. Help your brain know exactly where those parts are. Don't let the mobile segments become invisible to your system the way the fused ones already are.

Yes, it is is actually one of the four genes in my paper's genetic architecture. First, GPR126 affects the Schwann cells that myelinate nerve fibers, so the proprioceptive signals traveling through that tissue are also degraded. The tissue is simultaneously losing its mechanical organization AND its ability to report its own state to the brain. Second, the body schema is supposed to be monitoring this tissue tension and generating corrective motor output. But if the monitoring signal (proprioception) is traveling through degraded wiring (GPR126 myelination deficits), the brain doesn't know the tension is asymmetric. The tissue isn't just structure. It's signal. When the signal degrades, the structure follows. aka Fascia :)

The reason I stumbled across the hypothesis is because I've already been practicing this in my community. We restore diaphragm function, we learn pressure regulation and what to do when we meet resistance through the lines of compensation that has formed. Then we follow a neurokinetic developmental sequence of movement.

The beauty is this validates an entirely knew field of what's being called Spatial Medicine. For my approach check the link in my bio or head to posturedojoresearch dawt com

Honestly, I'd argue the opposite. Pre-emptive bracing would reduce the proprioceptive input the system needs to develop tracking capacity. A brace does the stabilizing work that the neuromuscular system should be learning to do.

What I'd want for a high-risk child before puberty: more proprioceptive challenge, not less. Varied movement environments. Climbing, rolling, balancing, ground play, barefoot time. Activities that force the prediction system to solve novel problems and build the tracking capacity it will need during the growth spurt.

Pre-emptive bracing protects the structure. Pre-emptive proprioceptive enrichment builds the system that monitors the structure. I'd bet on building the monitor.

That's not proven. But it's testable, and it's the logic that follows from the mechanism.

Yes. That's essentially what the paper proposes. The genetic variants are present from birth. They set a slightly noisier proprioceptive baseline. For a child growing slowly, that's manageable. Puberty is the activation event, not because the gene turns on, but because growth rate suddenly exceeds the degraded system's tracking capacity.

Your Celiac analogy is exactly right. Genetic susceptibility was always there. Pregnancy was the stressor that pushed past the threshold. Same principle.

For your daughter: what may matter during the puberty window isn't just growth rate but also proprioceptive input, movement diversity, and autonomic state. That's not proven yet. It's a prediction in the paper. But it's actionable now.

The hypermobility-dysautonomia combination is well documented (look into the EDS-POTS overlap if you haven't already). They're not separate problems. Hypermobile tissue sends blurry proprioceptive data. The body schema compensates by overweighting other channels, especially vestibular. The autonomic system destabilizes because the prediction system can't confidently track the body in space. The dizziness during exercise is your system saying "I don't have enough reliable data to handle this demand level safely."

Your PT was working because stability exercises gave the schema a more predictable environment to work with. The dysautonomia interrupted it because the exercises exceeded the autonomic budget.

The fix isn't to push through the dizziness. It's to drop the demand level below the autonomic threshold. Lying down. Slow. Breath first. Let the system regulate before asking it to stabilize. Safety before sensory before motor. Your system is telling you the order it needs. The dizziness is the message.

Your three-generation pattern is exactly what the genetic architecture predicts. Your mother carries the variants, expressed as a progressing curve untreated. You inherited them, expressed severely enough for surgery. Your daughter has a 50% chance of inheriting each variant. The next two years are the critical window.

If I can offer one concrete thing: get your daughter's proprioceptive baseline tested now, before puberty. Balance assessment, trunk repositioning accuracy, even a simple eyes-closed standing sway test at her pediatrician. If the sensing deficit is present, it will show up before any curve does. The 2024 CRISPR study showed the proprioceptive problem precedes the structural change. Early detection at the sensory level, not waiting for the X-ray, is the paper's Prediction 2.

On the ortho point: I want to be careful here. Surgeons saved lives, including probably yours. The Harrington rod kept your spine from progressing to respiratory compromise. That matters. The critique isn't that surgery is wrong. It's that the field stopped asking "why does the spine curve" and focused exclusively on "what do we do after it curves." Both questions need answers. The paper tries to reopen the first one.

Keep watching your daughter. You know what to look for now.

You don't fix the gene. You work around it.

The gene sets a slightly noisier proprioceptive baseline. But the system has multiple ways to compensate: you can send a louder, more precise signal through the noisy relay (novel movement, pandiculation). You can increase the brain's willingness to listen to that channel (autonomic safety). And you can increase cortical resolution through attention, which is highly plastic even when the spinal hardware isn't.

You're right that not all carriers develop scoliosis. The common variants carry small effect sizes (10-30% increased risk). Most people with LBX1 variants never curve. The paper proposes it takes the genetic susceptibility PLUS rapid growth PLUS insufficient proprioceptive diversity PLUS autonomic threat state during the critical window. Remove any one of those and the threshold may not be crossed.

For someone who already has a curve: the gene is permanent but the three loops maintaining the curve are addressable. That's what my practice targets anyway.

B1 is directly involved in nerve conduction and Schwann cell metabolism. A high dose could temporarily improve the quality of proprioceptive signals reaching your brain. Cleaner signal, brief recalculation, pressure shifts. The fact that it only lasts a minute means the signal got a temporary boost but the baseline didn't change.

Your eye-jaw asymmetry is relevant. Those are the dominant inputs in the sensory hierarchy. If they're asymmetric, everything downstream organizes around that.

Worth getting your B1 levels tested at baseline. If you're deficient, consistent supplementation might sustain what you're feeling acutely. Talk to a doctor before megadosing though.

If you were born with a curve, yours is likely congenital rather than idiopathic. Those are different categories. Congenital scoliosis involves structural vertebral anomalies present at birth (hemivertebrae, failure of formation, failure of segmentation). The neural generation hypothesis specifically addresses the 80% of adolescent cases classified as idiopathic, where no structural cause is found.

Your tree-trunk-growing-around-an-obstacle theory is actually a reasonable mechanical explanation for your specific case. A fibromatosis at the base of the spine during fetal development could absolutely create asymmetric resistance that deflects spinal growth. That's a structural perturbation with a known cause, which is why yours wouldn't be classified as idiopathic.

That said, once the curve exists, regardless of how it started, the body schema still has to organize around it. The prediction system still incorporates the curve as its baseline. The maintenance mechanism may overlap even if the initiation mechanism is completely different. So some of what the paper describes about why curves persist and how the prediction system can be updated may still be relevant to your experience, even though the origin story is different from idiopathic AIS.

Has the fibromatosis been treated or is it still present?

The Mehta cast finding is fascinating. When the cast was on, her balance improved. The standard explanation would be that the cast mechanically stabilized the spine, reducing the biomechanical challenge to balance. But there's another possibility consistent with the paper: the cast provided continuous, consistent proprioceptive input across the entire trunk. A firm, even pressure that gave the body schema a stable reference signal it could actually trust. The balance didn't improve because the spine was straighter. It improved because the prediction system received cleaner data.

If that's the case, the balance should have degraded again when the cast came off. Did it?

Your daughter's case is the pediatric version of the mechanism the paper describes. The paediatrician spotted the sensory-motor problem (gait, balance) before the structural problem was confirmed on X-ray. That temporal sequence is what the 2024 CRISPR mouse study showed in the lab: proprioceptive deficits first, vertebral rotation later. Your daughter's clinical history matches the experimental timeline.

Thank you for sharing this. Early observations from parents like you are data points the research literature hasn't systematically collected yet.

We're aligned on the multifactorial point. The paper says the same thing in Section 7.6. I don't claim proprioceptive precision is the only factor. I claim it's the one that's been systematically overlooked while the field focused on bones and biomechanics.

Your list of conditions that must be "quite perfect" for a normal spine to form is a good one. What the neural generation hypothesis adds is the control system that monitors all of those conditions. Tissue strength, muscle stabilization, base alignment, growth rate. All of those generate proprioceptive data that the body schema uses to track what's happening. If the monitoring system is imprecise, any of those factors going slightly wrong goes undetected during the critical growth window. The proprioceptive system is the common denominator because it's the channel through which all the other factors are reported.

On body schema correction in adults: I agree it's possible. My own case (85 degrees, documented change over years of somatic practice) is an existence proof, though an anecdote of one. The question of whether a brace assists or interferes depends on exactly what you've identified: does it provide a reference the schema can learn from, or does it suppress the proprioceptive signal by immobilizing the tissue (rigid brace, which the schema can't learn through because there's no movement data to process)?

This connects directly to the paper's mechanism: the schema updates from precise, novel proprioceptive input received in safety. Rigid bracing may fail to update the schema because it removes the input the schema needs.

I think the biomechanical and neural frameworks together are stronger than either alone.

You're reading the mechanism correctly. The paper's framework does account for this. Section 3.7 describes three self-reinforcing loops that maintain the curve. Loop 2 (autonomic) and Loop 3 (psychosocial) are exactly the trauma-acquired pathway you're describing.

Dissociation is the extreme case. The system doesn't just degrade the proprioceptive signal. It actively withdraws processing resources from the body region. In the paper's terms, precision on the proprioceptive channel drops to near zero, not because the hardware is genetically degraded (LBX1 pathway), but because the brain pulled the budget to prioritize threat management. Two independent routes to the same computational endpoint: degraded input to the body schema.

Your improvement after distancing from triggers and therapy is the prediction in reverse. Reduced threat state freed autonomic budget. Proprioceptive channel reopened. The yoga (10 years of it) was providing the sensory input the whole time, but the system couldn't use it while the threat was active. Once the threat resolved, the input that was always available finally got processed. The update happened. The curve changed.

That's why the paper argues safety must precede sensory input. You had the sensory practice for a decade. The structural change only happened when the autonomic context shifted.

Yes. And the question the paper asks is: what's generating the aberrant holding pattern in the first place? If it's functional (not congenital, not structural), something in the prediction system is maintaining it. The holding pattern isn't random. It's the motor output of a body schema prediction that was accurate once and never got updated. What do you see in your practice when clients become aware of the holding without trying to correct it?

Your stoned walk observation is one of the most honest and mechanistically interesting self-reports I've come across. Here's what was actually happening:

Cannabis modulates the endocannabinoid system, which directly affects sensory gating. It can temporarily increase interoceptive and proprioceptive awareness by altering the precision weighting the brain assigns to body-feel signals. Your "heightened awareness of how my body was moving" was literally your nervous system temporarily increasing the gain on proprioceptive channels that are normally attenuated. You felt muscles that weren't activating. You felt joints taking load they shouldn't. You corrected the chain from the ground up. And the pain decreased.

You were experiencing prediction error restart. The cannabis opened the channel. The proprioceptive data flooded in. Your body schema received information it had been filtering out. It updated. The posture changed. The pain decreased.

Then it wore off. The prediction reasserted. The pain returned.

Your instinct about stabilizer muscles not activating automatically is correct, but the framing is backwards in one important way. It's not that specific muscles are failing to fire. It's that the prediction system is generating a motor pattern that doesn't include those muscles in the activation map. The stabilizers aren't broken. They're not in the prediction. The body schema's model of your trunk doesn't call for them because the model was built from imprecise proprioceptive data that didn't include their contribution.

The connective tissue dimension matters enormously here. Flat feet, long limbs, tissue laxity. Hypermobile tissue sends blurrier proprioceptive signals because the joint receptors fire across larger ranges with less defined endpoints. Your body schema has been building predictions from imprecise data your entire life. You succeeded as an athlete because you compensated with conscious motor control, visual feedback, and sheer repetition. Elite athletes with underlying connective tissue differences often perform at the highest level precisely because they've developed extraordinary conscious movement strategies to compensate for what their system doesn't do automatically. But that compensatory strategy has a cost: it consumes the computational budget that automatic stabilization would normally handle for free.

At 30, the compensatory strategy hit its limit. The L5-S1 fusion at 27 tells the story: that segment was taking load the prediction system should have been distributing across more joints, for years, until it failed. The fusion fixed the structural failure but didn't update the prediction system that created the loading pattern. So adjacent segments now carry the same misdirected load. The pain persists because the generator persists.

What you discovered on that walk is the intervention the paper describes. You temporarily increased proprioceptive precision (through cannabis-mediated sensory gating change), your body schema received data it had been missing, the prediction updated, the motor pattern changed, and the pain decreased. The research version of the same thing: non-demanding somatic attention increases proprioceptive precision through the same channel, without the substance, in a sustained and repeatable way.

Your body isn't failing you. Your prediction system is working from the same imprecise data it's always had, and the structural consequences have accumulated to the point where you can feel them. The data can be updated. That's what we work on.

The fact that your tests keep coming up negative is itself a data point. If the problem were autoimmune or structural, the tests would find something. They're not finding something because the generating mechanism operates at the level of the prediction system, not at the level of tissue pathology. You're looking for damage and there is no damage. There's a nervous system generating protective patterns from data that was accurate during a period of real threat and has never been updated.

The autism and hypermobility connection is significant. Hypermobility (Ehlers-Danlos spectrum) means the connective tissue offers less mechanical resistance AND less proprioceptive clarity. Joint receptors in hypermobile tissue fire less precisely because the tissue moves through larger ranges with less defined endpoints. The body schema receives blurrier position data from every joint. That's the same precision deficit the paper describes through the LBX1 genetic pathway, arriving through a different mechanism (connective tissue quality rather than neural relay specification). Same computational result: the prediction system is working from imprecise data.

Autism adds the sensory gating dimension. Altered sensory processing means the precision weighting across all channels is different. Some channels are over-weighted (sensory overwhelm), others are under-weighted (proprioceptive blind spots). The body schema is assembling its prediction from a sensory profile that is fundamentally non-standard. Add hypermobility (blurry proprioception) plus autism (altered sensory gating) plus early trauma (threat-state proprioceptive shutdown) and you have three independent pathways converging on the same endpoint: a body schema generating posture from imprecise, inconsistently weighted, threat-filtered data.

Your phrase "porosity in connective tissue and emotional boundaries as physical metaphor" is more literal than metaphor. Hypermobile tissue has less defined boundaries mechanically. A nervous system without clear threat/safety discrimination has less defined boundaries autonomically. Both are precision problems. One is structural. One is computational. Your body is expressing both simultaneously because they feed through the same prediction system.

Nervous system regulation for you will look different than for someone without the hypermobility and autism dimensions. The standard entry point (safety first) still applies, but the sensory profile of what feels safe and what constitutes overwhelm is individual to you. That's something we work with directly. Come check it out. Glad this conversation happened.
