Inclusion criteria

Inclusion criteria: 1. Children (10–15 years old inclusive) with a diagnosis of AIS; (some patients recruited at age 15 may be 19 years old by the time they have completed their 2 years after skeletal maturity follow-up) 2. Risser 0, 1 or 2 3. Curve size (Cobb angle) between 20 and 40 degrees inclusive at baseline 4. Curve apex at or below T7 5. Participants and their parent/legal guardian must have a good understanding of the English language to ensure they understand what is required as part of the trial Added 14/05/2024: BASIS 2: 1. Participants enrolled on the BASIS study 2. RAC confirms skeletal maturity (Risser 4 in girls, Risser 5 in boys) with a Cobb angle less than 50o

Exclusion criteria

Exclusion criteria: 1. Secondary causes of scoliosis (i.e. neurological abnormalities and abnormal imaging) 2. Previous bracing or spinal surgery 3. Child or parent is unable to adhere to trial procedures or complete follow-up

Design outcomes

Primary

MeasureTime frame
1. Curve progression is measured using the Cobb angle (measured from x-ray), every 6 months, before skeletal maturity, and then at 1 and 2 years post skeletal maturity. Added 14/05/2024: BASIS 2: Curve progression from baseline to 2 years after skeletal maturity, in degrees. These will be assessed by the Central Measurement Team.

Secondary

MeasureTime frame
1. Quality of life is measured using the Scoliosis Research Society 22 questionnaire, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 2. Health related quality of life is measured using the CHU9D questionnaire, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 3. Psychological effects of bracing is measured using the Bad Sobernheim Stress Questionnaire questionnaire, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 4. Quality of life is measured using the Revised Children's Anxiety and Depression Scale (RCADS 25) questionnaire, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 5. Sleep disturbance is measured using the PROMIS Paediatric Sleep Disturbance Short Form 4a tool, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 6. Sleep-related impairment is measured using the PROMIS Paediatric Sleep Related Impairment Short Form 4a tool, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 7. Patient satisfaction with their brace treatment is measured using the Modified Client Satisfaction with Device module of the Orthotics and Prosthetics Users' Survey (CSD-OPUS) questionnaire, annually. 8. Education information and attainment is measured using a bespoke questionnaire, once, after the patient has completed their GCSEs (or equivalent). 9. Patient cost is measured using a bespoke questionnaire to the parents, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 10. Healthcare resource use is measured using a bespoke questionnaire to the parents, every 6 months until skeletal maturity, and then at 1 and 2 years post skeletal maturity. 11. School attendance is measured using a bespoke questionnaire to the parents, every 6 months until skeletal maturity, and then at 1 and 2 years post skel
