Does Pilates Help Scoliosis? What the Research Says
Scoliosis is a three-dimensional curve of the spine. Exercise cannot straighten a structural curve, but the research on scoliosis-specific exercise — and, more recently, on Pilates — shows it can do more than most people expect.

Partly. Scoliosis-specific exercise (Schroth, active self-correction) has randomised evidence for slowing curve progression in adolescents, and small trials plus a 2021 meta-analysis suggest Pilates reduces pain and improves Cobb angle — but the Pilates evidence is low quality and cannot replace bracing or specialist care.
Early trials and mechanistic evidence are encouraging, but high-quality Pilates-specific trials are still few.
For physiotherapeutic scoliosis-specific exercise (PSSE) such as Schroth and active self-correction, three single-centre randomised trials and the international SOSORT guidelines support a real effect on curve severity, muscle endurance and quality of life in adolescents. For Pilates specifically, a 2021 meta-analysis of ten small trials and a 2024 systematic review report improvements in Cobb angle, trunk rotation, pain and quality of life — but the trials are small, mostly fair-to-poor quality, and several involved non-structural (functional) curves. Pilates is a promising adjunct, not a proven stand-alone treatment, and bracing remains the evidence-based intervention for progressing curves in growing adolescents.
Key findings from the research
- Six months of Schroth exercises added to standard care produced a 3.5° smaller largest curve than standard care alone (95% CI -1.1° to -5.9°), with the Schroth group improving by 1.2° while controls worsened by 2.3° (Schreiber 2016, PLoS ONE).
- The same trial found Schroth exercise improved back-muscle endurance by 27.5 seconds more than controls at three months, plus better SRS-22r pain and self-image scores at six months (Schreiber 2015, Scoliosis).
- In 110 adolescents with mild curves (Cobb under 25°), active self-correction and task-oriented exercise reduced the Cobb angle by more than 5° while traditional exercise left it unchanged, with effects lasting at least a year after treatment ended (Monticone 2014, Eur Spine J).
- Supervised Schroth exercise in clinic reduced Cobb angle by 2.53° and trunk rotation by 4.23° over 24 weeks; an unsupervised home programme did not, and untreated controls progressed (Kuru 2016, Clin Rehabil).
- A meta-analysis of 10 RCTs (359 participants) found Pilates reduced Cobb angle, trunk rotation and pain and improved trunk mobility and quality of life, but rated the evidence fair-to-poor and urged caution (Gou 2021, Medicine).
- In 31 female students with non-structural scoliosis, Pilates reduced Cobb angle (38% mean change), improved trunk flexion and cut pain by 60% compared with no intervention (Alves de Araújo 2012, J Bodyw Mov Ther).
- Bracing for at least 18 hours a day achieved treatment success (no progression to 50°) in 72% of high-risk adolescents versus 48% under observation — the benchmark exercise has not matched (Weinstein 2013, NEJM).

2016 SOSORT guidelines: orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth
Finding: The International Society on Scoliosis Orthopaedic and Rehabilitation Treatment updated its guidance following new high-quality trials on bracing and physiotherapeutic scoliosis-specific exercise (PSSE). It issued 12 recommendations on PSSE to prevent progression during growth and 6 on PSSE alongside bracing or surgery, with 13 PSSE recommendations reaching strength B. The authors noted that heterogeneity of protocols limits generalisability and called for standardised research methods.
Why it matters here: Exercise with scoliosis-specific principles — three-dimensional self-correction, asymmetric strengthening, integration into daily posture — is endorsed by the leading conservative-treatment society, but as part of a supervised plan.
-
Schroth physiotherapeutic scoliosis-specific exercises added to the standard of care lead to better Cobb angle outcomes in adolescents with idiopathic scoliosis
Finding: Adolescents with curves of 10°–45° were randomised to standard care (observation or bracing) with or without a Schroth programme of 30–45 minutes daily home exercise plus weekly supervised sessions. At six months the Schroth group had a 3.5° smaller largest curve than controls (intention-to-treat; 4.1° per protocol) and a smaller sum of curves, with the difference growing with curve severity.
Why it matters here: A daily, supervised scoliosis-specific exercise habit can hold or slightly improve a curve over six months where observation alone allows progression.
-
The effect of Schroth exercises added to the standard of care on the quality of life and muscle endurance in adolescents with idiopathic scoliosis
Finding: In the same cohort, back-muscle endurance (Biering-Sørensen test) improved by 32.3 seconds in the Schroth group versus 4.8 seconds in controls at three months. Between three and six months the Schroth group improved in SRS-22r self-image and pain while controls deteriorated. High ceiling effects on questionnaires limited sensitivity.
Why it matters here: Trunk endurance and self-image respond to scoliosis-specific exercise within three months, independent of whether the curve angle changes.
-
Active self-correction and task-oriented exercises reduce spinal deformity and improve quality of life in subjects with mild adolescent idiopathic scoliosis
Finding: Adolescents with mild curves (Cobb under 25°) were randomised to active self-correction with task-oriented spinal exercises and education, or to traditional spinal exercises. The experimental group's Cobb angle decreased by more than 5° while the control group remained stable; angle of trunk rotation and SRS-22 quality of life also favoured the experimental group, and the effects lasted at least one year after treatment ended.
Why it matters here: How you exercise matters: generic spinal exercise held curves steady, but exercise built around active self-correction improved them.
-
The efficacy of three-dimensional Schroth exercises in adolescent idiopathic scoliosis: a randomised controlled clinical trial
Finding: Adolescents received supervised Schroth exercise in clinic, the same programme unsupervised at home, or no treatment. Only the supervised group improved: Cobb angle fell 2.53°, trunk rotation 4.23° and rib hump height decreased. The home-exercise group did not improve and the control group's scoliosis progressed. Quality of life did not change significantly in any group.
Why it matters here: Supervision and correct technique appear essential — a self-directed programme needs precise instruction, feedback and regular review to reproduce clinic results.
-
Effects of bracing in adolescents with idiopathic scoliosis (BrAIST)
Finding: In skeletally immature adolescents with curves at high risk of progression, bracing achieved treatment success (skeletal maturity without progression to 50°) in 72% versus 48% under observation. In the randomised cohort alone success was 75% versus 42%. Benefit rose with hours of brace wear, and the trial was stopped early for efficacy.
Why it matters here: For growing adolescents with progressing curves, bracing is the proven intervention; exercise should sit alongside it, not replace it.
-
The effectiveness of the Pilates method: reducing the degree of non-structural scoliosis, and improving flexibility and pain in female college students
Finding: Female students with non-structural scoliosis who completed Pilates-based therapy showed a significant reduction in Cobb angle (38% mean change), an 80% increase in trunk-flexion range and a 60% reduction in perceived pain, with no change in the control group. Between-group differences were significant for all three outcomes.
Why it matters here: The large angle change reflects non-structural (postural, correctable) curves in young adults — encouraging for functional scoliosis, but not evidence that Pilates reverses structural curves.
-
The effect of Pilates exercise training for scoliosis on improving spinal deformity and quality of life: meta-analysis of randomized controlled trials
Finding: Pilates training was associated with reduced Cobb angle (standardised mean difference 1.23), reduced angle of trunk rotation (1.37) and pain (2.78), and improved trunk range of motion (1.23) and quality of life (3.05). Mean PEDro quality score was 5.3 out of 10 (fair). The authors concluded Pilates may help but that, because of the poor quality of the evidence, results should be interpreted with caution.
Why it matters here: The direction of effect is consistently positive across small trials, but the size of the effects is unreliable until larger, better-controlled studies are done.
-
Effects of Pilates exercises on spine deformities and posture: a systematic review
Finding: Studies of Pilates or Pilates-combined programmes reported improvements in Cobb angle, angle of trunk rotation, range of motion, chest expansion, SRS-22r scores and postural measures, alongside pain relief and better function. PEDro scores ranged from 3 to 8. The authors judged the evidence positive but stated more research is needed before Pilates can be validated as a physical therapy for spinal-deformity rehabilitation.
Why it matters here: The most recent synthesis supports Pilates for posture, mobility and symptoms in scoliosis while stopping short of calling it an established treatment.
How Pilates is thought to help scoliosis
A scoliotic spine is not just bent sideways: it is rotated and the trunk muscles on each side work unevenly. Scoliosis-specific exercise teaches active self-correction — elongating the spine, de-rotating the rib cage and breathing into the collapsed side — then strengthens the trunk in that corrected position so the correction becomes habitual.
Pilates shares much of this toolkit: axial elongation, lateral breathing, asymmetric loading and precise control of pelvis and rib cage. When adapted by an instructor who understands the individual curve pattern, it becomes a way to train the corrected posture in functional movement rather than only in static holds.
The symptomatic benefits — less pain, better trunk endurance, greater mobility and improved self-image — appear to come from stronger, more balanced trunk musculature and from moving with more confidence. These gains are reported even in trials where the Cobb angle changed little, which is why they matter for adults whose curves are fixed.
What the evidence does not tell us
- Pilates-specific trials are small (10 to 60 participants), mostly rated fair-to-poor quality, and several studied non-structural or functional curves in young adults, whose large angle improvements do not translate to structural scoliosis.
- The strongest randomised evidence is for Schroth and active self-correction in adolescents with idiopathic scoliosis, not for Pilates, and not for adults with established or degenerative curves.
- Cobb angle changes in exercise trials are modest (roughly 2°–5°) and measurement error on radiographs is itself around 3°–5°, so small differences should be read cautiously.
- Long-term follow-up is rare; most trials end at six months and few report what happens after supervised sessions stop, although Monticone found effects persisting at one year.
- Supervision appears critical — unsupervised home exercise failed to improve curves in the Kuru trial — which limits how far results generalise to self-directed programmes.
Practical takeaways
- Exercise can influence scoliosis: randomised trials show scoliosis-specific programmes slow progression and modestly improve curves in adolescents, and Pilates-based programmes consistently reduce pain and improve trunk endurance and mobility.
- For growing adolescents with a progressing curve, bracing is the proven treatment; exercise complements it and should be coordinated with a scoliosis specialist.
- For adults with a fixed curve, the realistic goals are pain, posture, endurance and function — outcomes that trials show respond to exercise even when the angle does not change.
- Technique matters more than effort: exercises should be adapted to your curve pattern, emphasise elongation and de-rotation, and avoid movements that load the spine further into the curve.
- Get a baseline assessment and periodic review from a clinician; a daily habit of 20–45 minutes, as used in the trials, is more valuable than occasional long sessions.

Frequently asked questions
- Can Pilates help scoliosis?
- It can help the things that affect daily life. A 2021 meta-analysis of ten small randomised trials found Pilates reduced pain, improved trunk mobility and quality of life, and modestly reduced Cobb angle and trunk rotation, though the authors rated the evidence fair-to-poor. Larger, better trials exist for Schroth and active self-correction exercise, which share many principles with clinical Pilates. Pilates is best viewed as a well-supported adjunct rather than a proven stand-alone treatment for structural scoliosis.
- Can Pilates straighten a scoliotic spine?
- Not a structural curve. Trials of scoliosis-specific exercise in adolescents report Cobb angle improvements of roughly 2°–5° over six months, which is meaningful when the alternative is progression but is not straightening. The one Pilates trial reporting a 38% angle reduction studied non-structural (postural) curves in young women, which are correctable by definition. For adults with fixed curves, the realistic gains are less pain, stronger trunk muscles, better posture and easier movement.
- How often should I do Pilates or scoliosis exercises?
- The successful trials used daily practice. The Schroth trials prescribed 30–45 minutes of home exercise every day plus one supervised session a week for six months; Monticone's programme ran until skeletal maturity with effects lasting a further year. Frequency and correct technique both mattered: in the Kuru trial, the same exercises done unsupervised at home did not improve curves. A short daily routine reviewed regularly by someone who understands your curve is the evidence-based pattern.
- Is Pilates safe with scoliosis, and are there exercises to avoid?
- Pilates is generally safe for scoliosis and no serious adverse events were reported in the trials. The caution is about direction: movements that load or side-bend the spine further into the curve, deep loaded flexion, and repetitive twisting towards the rotated side can reinforce the asymmetry. Programmes should emphasise axial elongation, breathing into the concave side and strengthening in a self-corrected position. If you have a large or progressing curve, are still growing, or have had spinal fusion, get guidance from a scoliosis-trained clinician first.
- How long before I notice a difference?
- Symptom changes come first. In the Schreiber trial, back-muscle endurance improved significantly within three months, and pain and self-image scores improved by six months. Angle changes, where they occur, were measured at six months in the Schroth and Pilates trials and after longer programmes in Monticone's study. Expect to feel stronger and more comfortable within two to three months of consistent daily practice, and treat any radiographic change as a longer-term, supervised goal.
- Is mat or reformer Pilates better for scoliosis?
- No trial has compared them in scoliosis. The published Pilates studies used mat-based or mixed programmes, and the scoliosis-specific trials used floor and standing exercises with simple props. What the evidence points to is the content — elongation, de-rotation, asymmetric strengthening and breathing — rather than the apparatus. A reformer can add supported resistance, but a mat programme adapted to your curve pattern and practised daily is fully consistent with the research.
