Brace Weaning Protocol Comparing Gradual and Immediate Weaning

This is a non-blinded, randomized controlled trial for testing two brace weaning protocols namely immediate removal of brace or gradual weaning of brace over a course of 6 months for adolescent idiopathic scoliosis (AIS) patients. These patients will have follow-up visits at 6-months, 12-months and 24-months intervals. By comparing between the two groups in terms of change of Cobb angle, truncal balance, health-related quality of life measures at the set time-points, the investigators aim to gain insights of whether different brace-weaning protocol will be more beneficial in patients' clinical and quality of life measure outcomes.
