A Brace Must Address Both Correction and Progression — Not Just One
Exercise is essential for scoliosis during growth, but exercise alone is unlikely to stop deformity progression while the spine is still developing. Combining a dynamic brace like SPINECOR with targeted exercise gives patients the best chance of achieving both goals simultaneously: slowing curve progression and restoring muscle balance.
The most common misconception is that a brace will automatically restore the spine's angle. Before growth ends, the more important goal is preventing an already-deviated spine from worsening further; some degree of angle correction occurs in certain patients, but that is not the primary aim.
During growth, the bones and cartilage surrounding the spine change rapidly. When the load on the spine shifts unevenly to one side, growth itself begins to tilt toward the deformity. Without an external corrective force, that asymmetric loading is very difficult to change. A brace intervenes by redistributing the compressive forces on the spine — something that muscle strengthening or posture training alone cannot counteract at the mechanical level.
Physiotherapeutic scoliosis-specific exercises (PSSE) play an important role in improving muscle function and postural awareness. However, in patients with open growth plates, PSSE alone has not shown the same progression-inhibiting results as bracing (Seleviciene Vaiva et al., 2022). Exercise and bracing operate at different levels; neither replaces the other.
Why Exercise Alone Is Not Enough — Asymmetric Muscles Do Not Rebalance Without External Force
As scoliosis progresses, the muscles on either side of the spine develop differently. The muscles on the convex (outward-curving) side remain stretched and continuously under load, while the muscles on the concave (inward-curving) side shorten and stiffen. After months or years in this state, the problem goes beyond simple weakness — the shape and resting length of the muscles on each side become structurally different. That fixed asymmetry does not reverse with repeated strength training.
Growth makes this harder to overcome. When a child grows taller while one side of the spine is constantly compressed, the direction of bone growth itself tilts toward the compressed side. The more the child grows, the larger the deformity becomes. No matter how precise the strength training, exercise cannot eliminate the mechanical pull that already-tilted bone exerts.
This limitation is especially clear in growing patients with a Cobb angle of 25° or more. A pooled analysis of multiple studies found that exercise alone provided insufficient progression control in the angle range where bracing is typically recommended (Dong Huanrun et al., 2024). Even well-structured programs such as the Schroth method may not be sufficient as a standalone treatment without a brace (Seleviciene Vaiva et al., 2022).
This is not an argument against exercise — exercise remains a core part of treatment. The point is that exercise and bracing address different problems. The brace holds the direction of bone growth in check where exercise cannot reach.
The Evidence for Exercising While Wearing a Dynamic Brace
What sets SPINECOR apart from a conventional rigid brace is its design. Rather than a hard plastic shell, it uses a flexible elastic band system that keeps the muscles around the spine continuously moving and active. A rigid brace stabilizes the spine from the outside, which can allow the muscles to become less active as they offload onto the brace's frame. A dynamic brace is built to do the opposite.
That design is what makes exercising while wearing the brace meaningful. When a patient exercises while the brace is guiding the spine toward better alignment, the muscles repeatedly practice generating force from a corrected position. The nervous system records this as learned muscle activation in good alignment — not as strength built in a faulty posture. This process is called postural reprogramming.
Performing PSSE, such as the Schroth method, while wearing the brace has shown better outcomes for Cobb angle improvement and trunk rotation reduction than exercise alone (Dimitrijević Vanja et al., 2022). Muscle activation patterns learned while wearing the brace tend to persist after the brace is removed (Dong Huanrun et al., 2024). Training muscles within the postural conditions the brace creates is fundamentally different from training without those conditions — the muscles learn different movement habits.
In the beginning, exercising in the brace may feel awkward and restrictive. The flexible band design, however, accommodates the range of motion needed for PSSE, so supervised exercise sessions are generally feasible once patients become accustomed to it.
Wear Time and Treatment Timing — Growth Stage Determines Outcomes
Many patients who are prescribed a brace do not meet their recommended wear time, often because of discomfort or self-consciousness. Wear time, though, directly affects treatment results. The Scoliosis Research Society (SRS) recommends wearing the brace for at least 18 hours per day. Below that threshold, the brace cannot sustain its load-redistribution effect on the spine. Inconsistent wear produces inconsistent results.
The Risser grade describes how far the pelvic iliac crest has ossified (hardened into bone), and it serves as a practical marker for how much spinal growth remains. Grade 0 means ossification has not yet begun; grade 5 means it is complete. Starting treatment at Risser grades 0–2 is associated with greater progression control, while the benefit decreases sharply at grades 4–5 (Seleviciene Vaiva et al., 2022). By that later stage, the spinal structure is already consolidating toward its final form.
The growth window is short. During the pubertal growth spurt, the Cobb angle can change meaningfully within months. Passing through that period without treatment means entering adulthood with a larger curve. The time during which bracing can meaningfully influence the spine is finite — delaying treatment closes that window.
In clinical practice, many patients present for the first time already at Risser grade 3 or higher. Exercise therapy still has value at that point, but the opportunity for bracing to slow progression is already reduced. Getting evaluated before ossification is complete is what keeps the full range of treatment options available.
Bracing and Exercise Together — Neither Works Alone
A brace changes how load is distributed across the spine; exercise trains the muscles to activate correctly under those changed conditions. These are two distinct roles. A brace cannot substitute for exercise, and exercise cannot substitute for a brace.
A network meta-analysis found that the combination of exercise and bracing showed the most consistent results for both angle stabilization and muscle balance improvement (Dong Huanrun et al., 2024). Scoliosis is both a mechanical problem and a neuromuscular one, and treatment needs to address both dimensions at the same time (Dimitrijević Vanja et al., 2022).
A Cobb angle of 20° or more combined with a Risser grade of 0–2 is a reasonable threshold for actively considering combined brace-and-exercise treatment. Even below 20°, if a child is growing faster than 5 cm per year, regular follow-up X-rays are warranted — small curves can progress quickly during rapid growth.
Discomfort with wearing a brace, or the instinct that dedicated exercise should be enough, are understandable responses. But the fact that a child is still growing changes the calculus. A growing skeleton means the window for intervention is still open. Deciding when to begin evaluation and treatment during that window matters. Combined bracing and exercise is the current evidence-based conservative approach for making the most of the time that window remains open.

Frequently Asked Questions
Can't exercise alone control scoliosis progression during growth? Exercise is essential for maintaining muscle balance, but it cannot offset the asymmetric mechanical load that the spine experiences during growth. When the growth plates are still open and the Cobb angle is 25° or more, exercise without a brace may not provide sufficient progression control, because the load distribution through the spine needs to be corrected externally.
How is SPINECOR different from a rigid brace? A rigid brace stabilizes the spine from the outside, which can cause the surrounding muscles to become relatively less active while the brace bears the load. SPINECOR uses an elastic band system, so the muscles around the spine keep moving during wear. Patients can repeatedly activate their muscles from a well-aligned posture — the one the brace guides them into — rather than from a compensated position.
How many hours per day does the brace need to be worn? The Scoliosis Research Society (SRS) recommends at least 18 hours of wear per day. Falling below this threshold means the brace cannot sustain its effect on spinal load distribution, which limits its benefit. Inconsistent wear time produces correspondingly inconsistent treatment outcomes.
When is it appropriate to start combined brace-and-exercise treatment? A Cobb angle of 20° or more with a Risser grade of 0–2 is a reasonable point to actively consider combined treatment. Even below 20°, children growing faster than 5 cm per year are in a rapid growth phase that warrants regular monitoring; the start of treatment may be moved earlier depending on how the curve progresses.
Is bracing still useful after growth is nearly complete? At Risser grades 4–5, once ossification is nearly finished, the progression-inhibiting effect of bracing decreases substantially. After the growth plates have closed, exercise aimed at muscle balance and postural maintenance takes center stage, and the role and scope of bracing need to be re-evaluated compared with the growth period.
