Syntropic Core vs Schroth, physio and chiropractic
If you have scoliosis and you are comparing options, start here: Schroth has the strongest research evidence of any exercise approach for curves. We're putting that first on purpose.

What the evidence says about Schroth
In a randomized trial, 50 young people aged 10 to 18 with curves between 10° and 45° either kept their standard care or added six months of Schroth exercises, with a daily home program and weekly supervised sessions. The Schroth group's largest curve came out about 3.5° smaller than the standard care group's (Schreiber and colleagues, 2016, PLoS ONE).
The wider picture is more modest. A 2024 Cochrane review pooled 13 randomized trials of exercise for teenage scoliosis, with 583 participants. It found that exercise alongside a brace may mean less progression, that exercise alone may make little or no difference compared with no treatment, and that the evidence is low certainty overall, mostly because the studies were small (Romano and colleagues, 2024, Cochrane).
Put together: Schroth and similar scoliosis-specific exercise have more trial evidence on curves than anything else in the exercise world, and that evidence is still thin. Both sources above studied teenagers.
What each approach works on
Schroth works on the curve directly. A trained therapist teaches you three-dimensional exercises and a breathing pattern that lengthen the spine, reduce the rotation of the trunk and guide you into a less curved position, then helps you carry that position into daily life. For teenagers it is often used alongside a brace.
General physio works on strength, mobility and pain. A good physical therapist can help a lot with a sore back or a stiff hip. Unless they are trained in a scoliosis-specific method, the aim usually isn't the curve.
Chiropractic mostly works through hands-on adjustment of the spine and is usually aimed at pain and stiffness. If you see a chiropractor for scoliosis, it's fair to ask what they expect to change and how they will measure it.
Syntropic Core works on a different layer: how your nervous system organizes posture in the first place. The practice trains how you breathe, how you build pressure in your deep core, and your felt sense of where your body is in space. The idea is that posture is something your body keeps generating from its own map of itself, so instead of learning to hold a better position, you give that map new information to work with.
That idea is a hypothesis. Sam calls it the Neural Generation Hypothesis, and he has published it open access with a DOI. It is not peer reviewed, and we have no trial data comparing Syntropic Core with Schroth, physio or chiropractic. We don't claim to be better than any of them.
Side by side
| Syntropic Core | Schroth | General physio | Chiropractic | |
|---|---|---|---|---|
| What it works on | How your nervous system organizes posture: breath, deep-core pressure and your felt sense of where your body is. | The curve itself. Three-dimensional exercises and breathing to lengthen the spine, reduce the rotation and hold a less curved position. | Strength, mobility and pain. Usually not specific to scoliosis unless the therapist is trained in it. | Joint movement and back pain, mostly through hands-on spinal adjustment. |
| Who teaches it | Sam Miller and the Posture Dojo team. Educators, not clinicians. | Therapists trained and certified in the Schroth method. | Licensed physical therapists. | Licensed chiropractors. |
| How it's delivered | Online on Skool: live calls, recorded lessons, about 20 minutes of practice a day. | Sessions with a therapist plus a daily home program. In the trial above, 30 to 45 minutes a day. | Clinic sessions plus home exercises. | Clinic visits. |
| Research on curves | None. Member reports are self-reported with no control group. The idea behind it is a published hypothesis, not peer reviewed. | The most of any exercise approach, mostly in teenagers. Cochrane rates the overall exercise evidence as low certainty. | Depends on the method. General physio is not designed to change a curve. | We don't make claims about it here. Ask your chiropractor what they expect to change and how they'll measure it. |
| Claims about the bone | Won't straighten bone. Not a reason to delay a brace, surgery or check-ups. | Aims to slow progression and reduce the curve, especially during growth. | Usually aims at pain and function. | Usually aims at pain and stiffness. |
Many members combine them
Most people who join Syntropic Core have already tried something on this page. The thing we hear again and again is “it helped, it didn't stick.” Some keep their Schroth or physio sessions and add our practice on top. That's fine with us. These approaches work on different things, so doing more than one isn't a contradiction.
Who should pick what
- A teenager whose curve is still growing. Stay with the scoliosis team. Bracing and scoliosis-specific exercise such as Schroth are where the evidence is. Syntropic Core is built for adults.
- An adult whose main goal is a smaller number on the X-ray. Schroth is the approach with trials behind it. We won't promise you a Cobb change.
- Someone with a sore back who wants hands-on care. A physical therapist is a sensible first stop.
- An adult who did Schroth, physio or chiropractic and found it helped but didn't stick. That's who Syntropic Core was built for, especially if your breath sits high in your chest or staying upright takes constant effort.

Questions about Syntropic Core and Schroth
Is Syntropic Core better than Schroth?
We don't claim that. There is no trial comparing the two, so nobody can honestly say one beats the other. Schroth has published trials behind it. Syntropic Core has member reports and a hypothesis. Those are different kinds of evidence, and we'd rather you know which is which.
Can I do Syntropic Core and Schroth at the same time?
Yes, and many members do. A lot of people come to us after Schroth, physio or chiropractic and tell us the same thing: it helped, and it didn't stick. If you are seeing a therapist, tell them what you are practicing with us so they have the full picture.
Should my teenager do Syntropic Core instead of Schroth or a brace?
No. If a teenager's curve is still being monitored, the decisions about bracing, exercise and surgery belong with their scoliosis team. Syntropic Core is built for adults, and it is never a reason to delay a brace, a surgery or the check-ups that track a curve. Parents should talk to the child's clinician first.
What does the research say about Schroth?
A randomized trial of 50 young people aged 10 to 18 found that adding six months of Schroth exercises to standard care left the largest curve about 3.5° smaller than standard care alone (Schreiber and colleagues, 2016). A 2024 Cochrane review of exercise for teenage scoliosis rated the overall evidence as low certainty: exercise alongside a brace may slow progression, and exercise alone may make little or no difference compared with no treatment (Romano and colleagues, 2024). That is still more trial evidence on curves than any other exercise approach has.
Is Syntropic Core physical therapy?
No. It is education and practice, taught online. Syntropic Core is neurosomatic education, not medical treatment or advice, and does not diagnose, treat, or cure any condition. Consult your physician before beginning, especially with an acute injury, recent surgery, or a diagnosed spinal condition.
Does Syntropic Core change the Cobb angle?
We don't promise that. It won't straighten bone. What members commonly describe is how their body feels: breath, pain, effort, ease. If a measured curve is your main goal, Schroth is where the trial evidence is.
