To date, there is no objective assessment method for the quality of the self-correction performed by patients with scoliosis.

The study consists of two parts, both retrospective, and distinct on the basis of the tools used to assess self-correction.

Part 1: Retrospective assessment of the radiographic variations between spontaneous position and self-correction in subjects suffering from juvenile and adolescent idiopathic scoliosis. Both measurements were performed in a single session.

Part 2: Retrospective assessment of the variations between spontaneous and self-correcting position in subjects with juvenile and adolescent idiopathic scoliosis using objective parameters deriving from non-invasive 3D ultrasound instrumentation (Scolioscan, Telefeld, Hong Kong).

Inclusion Criteria for both parts:

• Diagnosis of juvenile or adolescent idiopathic scoliosis;
• Age >= 10 years;
• Single and double curves with amplitude >= 15 ° Cobb;
• Performing exercises according to SEAS for at least 6 months

Only for part 1 (radiographic)

• Availability of radiographic investigation in upright position and in self-correction Only for part 2 (ultrasound)
• Availability of ultrasound assessment in upright position and in self-correction
• Complete radiograph of the spine in anteroposterior projection performed in the 45 days preceding or following the medical examination.
• Risser between 0 and 2.

Exclusion Criteria:

For both parts:

• Patients with more than 2 scoliotic curves
• Patients with secondary scoliosis
• Patients suffering from learning disabilities or clinical conditions impairing neuromotor control
• Patients lacking the necessary measures to evaluate the outcome.

Part 2 only (ultrasound)

● Patients undergoing brace treatment

Patients with adolescent and juvenile idiopathic scoliosis.
