Resisted inspiratory muscle training plus Schroth exercises for adolescent idiopathic scoliosis
Official title: The Effects of Resisted Inspiratory Muscle Training Applied in Addition to PSSE-Schroth Exercises on Clinical Outcomes in Individuals With Adolescent Idiopathic Scoliosis.
Run by Hacettepe University · NCT07321600 · Data updated 2026-11-12
This trial will test whether adding resisted inspiratory muscle training to Schroth exercises helps teenage girls with idiopathic scoliosis improve spine alignment, breathing strength, and physical function.

Is this trial a fit for you?
✓Likely a good fit
Female adolescents aged 10–18 years with idiopathic scoliosis, Cobb angle 10°–45°, angle of trunk rotation ≥5°, and skeletal immaturity (Risser ≤3 and Sanders ≤4) who can attend supervised sessions are ideal candidates.
✕Probably not a fit
Patients with non-idiopathic scoliosis, prior spinal surgery, major cardiopulmonary contraindications, severe curves outside the inclusion range, recent participation in PSSE/IMT, or inability to adhere to supervised sessions are unlikely to benefit from this protocol.

What this trial studies
This is a prospective randomized controlled trial that will assign eligible female adolescents with idiopathic scoliosis to either a standardized PSSE-Schroth exercise program alone or the same program plus resisted inspiratory muscle training. Both groups will receive supervised sessions three times per week for 8 weeks (24 sessions total). Outcomes measured before and after the intervention include clinical spinal measures (Cobb angle, angle of trunk rotation, Posterior Trunk Symmetry Index), respiratory muscle performance and walk capacity, biomechanical and functional tests (balance, 3D kinematics, plantar pressure, isokinetic strength), sleep quality, and health-related quality of life. The study aims to determine if the addition of IMT provides measurable benefits beyond Schroth exercises alone.
Why it matters
Potential benefit: If successful, adding resisted inspiratory muscle training could further improve respiratory muscle strength, posture symmetry, and functional capacity compared with Schroth exercises alone.
How similar studies have gone: While Schroth and other PSSE approaches have shown clinical benefit, the specific combination of structured resisted IMT with PSSE is relatively untested and prior evidence on added value is limited.
