Inclusion criteria

Inclusion criteria: - In-patient stay at the Asklepios Katharina Schroth Clinic in Bad Sobernheim - Diagnosis of primary adolescent idiopathic scoliosis

Exclusion criteria

Exclusion criteria: - Resting pain > 4/10 on a visual analog scale (VAS; 0 = no pain, 10 = worst pain) - Diagnosis of congenital, infantile, or juvenile scoliosis - Diagnosis of secondary scoliosis - Cobb angle 50° - Influence of medication affecting balance, muscle tone, and/or alertness - Body mass index (BMI) > 30 kg/m² - Alterations of back contour (e.g. large scars or extensive tattoos) - Patients with intellectual disability or prior spinal fusion surgery - Presence of any acute illness other than scoliosis

Design outcomes

Primary

MeasureTime frame
- Endpoint: Difference in the scoliosis angle measured by rasterstereography - Assessments: Baseline examination and measurement after 20 minutes of sitting - Method: Rasterstereographic assessment with the DIERS formetric III 4D average system

Secondary

MeasureTime frame
- Course of the measured parameters over the sitting period (measurements every 5 minutes) - Difference between the scoliosis angle at baseline and the scoliosis angle on the even surface after 20 minutes of sitting - Subjective sitting comfort assessed using a numerical rating scale at baseline and after 20 minutes of sitting
