NCT03329716

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change of Cobb Angle

    Cobb angle changes between baseline (when decision to initiate brace weaning is made) and subsequent follow-ups.

    Baseline, then 6-months, 12-months and 24-months follow-ups

Secondary Outcomes (3)

  • Truncal balance changes

    Baseline, then 6-months, 12-months and 24-months follow-ups

  • Health-related Quality of Life measure

    Baseline, then 6-months,12-months and 24 months follow-ups

  • Health-related Quality of Life measure

    Baseline, then 6-months,12-months and 24 months follow-ups

Interventions

For AIS patients who have been wearing Boston brace and attend clinic consultation where the decision for brace weaning is made, then weaning protocol of either arm will be prescribed

Eligibility Criteria

Age11 Years - 16 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • AIS patients who have been wearing underarm (Boston) bracing, and who have reached skeletal maturity based on the Scoliosis Research Society (SRS) standardized criteria: Risser stage ≥4, \>2 years post-menarche, and no growth between 2 visits. The subjects should be managed at the Duchess of Kent Children's Hospital (DKCH) in Hong Kong.

You may not qualify if:

  • All patients that are not AIS, using Milwaukee bracing, unable to comply with study follow-up, protocol issued and refused consent for study
