Outcome Measures

Primary Outcomes (1)

  • In-brace Correction (IBC)

    Although bracing is considered to be useful, its effectiveness hinges on various factors one of which is the in-brace curve correction, ie In-brace Correction (IBC). IBC is defined as the percentage of Cobb angle change during an X-ray with the brace fitted on the patient.

    From date of randomization, assessed up to 2 years after bracing stopped at skeletal maturity

Secondary Outcomes (2)

  • Curve progression

    From date of randomization, assessed up to 2 years after bracing stopped at skeletal maturity

  • Quality of life questionnaires

    From date of randomization, assessed up to 2 years after bracing stopped at skeletal maturity

Study Arms (2)

Hybrid Bracing

EXPERIMENTAL

Hybrid Bracing Protocol (HyBP) combining the use of daytime Underarm Brace (UAB) and a nighttime Lateral Bending Brace

Other: Hybrid Bracing

Conventional fulltime underarm bracing (UAB)

ACTIVE COMPARATOR

Conventional group uses fulltime underarm bracing (UAB)

Other: Conventional fulltime Underarm Bracing

Interventions

Hybrid Bracing includes daytime Underarm Brace(UAB) and nighttime Lateral Bending Brace(LBB)

Hybrid Bracing

Conventional group includes fulltime Underarm Brace (UAB) only.

Conventional fulltime underarm bracing (UAB)

Eligibility Criteria

Age10 Years - 18 Years
Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Females with AIS diagnosed after detailed clinical and radiological evaluation by an experienced orthopaedic surgeon and
  • having a single lumbar or thoracolumbar curve with Cobb angle between 20° - 40° and
  • age 10 years and older when bracing is prescribed and
  • Risser 0 to 2 and
  • either pre-menarchal or less than 1 year post-menarchal and
  • with no prior treatment for scoliosis

You may not qualify if:

  • presenting with associated musculoskeletal, neurological or other conditions possibly responsible for the curvature
  • with previous surgical or orthotic treatment or
  • physical or mental disability that prevent patients from complying with the bracing protocol
