🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.

Frontiers in Pediatrics (2026) - Systematic Review and Network Meta-Analysis
Key Findings
- Across 13 comparative studies involving 709 adolescents, non-surgical treatment showed a pooled Cobb-angle effect of SMD -1.39 (95% CI -2.20 to -0.59), with high heterogeneity (I²=95.1%).
- Bracing and Schroth-related therapies showed a trend toward improved short-term Cobb-angle control, but estimates were imprecise and SRS-22 evidence remained limited.
📋 Practice Implication: Use this network review to frame conservative options, but avoid treating treatment rankings as definitive when counseling families because the evidence network is sparse and heterogeneous.

BMC Musculoskeletal Disorders (2025) - Systematic Review and Meta-Analysis
Key Findings
- Across 18 RCTs involving 1,014 patients, PSSE improved Cobb angle (SMD -1.00; 95% CI -1.47 to -0.53), angle of trunk rotation (SMD -1.15; 95% CI -1.94 to -0.36), and quality of life (SMD 0.63; 95% CI 0.15 to 1.11).
- Exercise performed at least three times weekly produced greater improvements than lower-frequency practice in subgroup analyses.
📋 Practice Implication: When prescribing PSSE, favor an individualized program that can be performed at least three times weekly when feasible, while setting expectations around adherence and exercise dose.

BMC Musculoskeletal Disorders (2025) - Systematic Review and Meta-Analysis
Key Findings
- PSSE was associated with mean improvements of 4.50° in Cobb angle and 2.27° in angle of trunk rotation, with significant heterogeneity across studies.
- Thoracic kyphosis improved by 4.97° and health-related quality of life improved by 0.14; Schroth plus bracing reduced Cobb angle by 2.79° in moderate AIS.
📋 Practice Implication: Use the subgroup findings to match conservative care to curve severity: combined Schroth exercise and bracing may be especially relevant for moderate AIS, while average Cobb-angle gains may remain modest.

Spine (2025) - Systematic Review and Meta-Analysis
Key Findings
- Neural-axis abnormalities occurred in 19.4% of patients with atypical-laterality curves versus 12.1% with typical laterality.
- Syringomyelia prevalence was 12.4% versus 6.1%, while Arnold-Chiari syndrome prevalence was 12.0% versus 7.7% for atypical versus typical curves.
📋 Practice Implication: Atypical curve laterality should lower the threshold for MRI evaluation or specialist review for neural-axis pathology, particularly with left thoracic or right lumbar patterns.
|
Archives of Physical Medicine and Rehabilitation (2025) - Systematic Review and Meta-Analysis
Key Findings
- Scoliosis angle and asymmetry index were sufficiently valid versus radiographic measures, with high-quality evidence supporting those results.
- Sagittal thoracic kyphosis and lumbar lordosis were sufficiently valid versus X-ray measures, while vertebral-rotation validity was insufficient and coronal responsiveness remained inconsistent.
📋 Practice Implication: Position surface topography as a radiation-free adjunct for screening and serial assessment, not a standalone replacement for radiographs when vertebral rotation or progression is the key question.

Summary
The highest-significance evidence supports physiotherapeutic scoliosis-specific exercise and other conservative strategies as improving Cobb angle, trunk rotation, and quality of life in adolescents with idiopathic scoliosis, with the strongest exercise signal at three or more sessions per week. Bracing and Schroth-based approaches appear favorable for short-term curve control, but heterogeneity, modest effects, limited SRS-22 data, and measurement limitations argue for individualized treatment; atypical curve laterality is associated with more neural-axis abnormalities and warrants heightened diagnostic attention.
