Adolescent idiopathic scoliosis is a three-dimensional spinal deformity characterized by lateral curvature and vertebral rotation, commonly developing during adolescence. It is associated with postural asymmetry, trunk deformity, reduced pulmonary function, and decreased quality of life. Conservative management strategies, particularly exercise-based interventions, are widely used to prevent progression and improve functional outcomes.
Core stabilization exercises focus on strengthening the muscles surrounding the spine, including abdominal, paraspinal, and pelvic muscles. These exercises enhance spinal stability, improve postural control, and reduce compensatory movement patterns. However, core stabilization alone may not fully address thoracic asymmetry and respiratory limitations associated with scoliosis.
Rotational angular breathing exercises are scoliosis-specific techniques aimed at improving thoracic expansion, promoting spinal de-rotation, and enhancing pulmonary function. These exercises involve controlled breathing patterns that target the concave side of the rib cage, facilitating improved ventilation and postural correction.
Although both interventions have shown individual effectiveness, limited evidence exists regarding their combined effects on structural, functional, and patient-reported outcomes in adolescents with idiopathic scoliosis. Therefore, this study aims to evaluate the combined impact of core stabilization and rotational angular breathing exercises on multiple clinical outcomes.
This study will be conducted as a single-blind, randomized controlled trial with two parallel groups. A total of 32 participants meeting eligibility criteria will be recruited and randomly assigned in a 1:1 ratio to either the experimental group or the control group.
Participants in the experimental group will undergo a supervised exercise program consisting of core stabilization exercises (planks, bridges, bird dog, and dead bug) combined with rotational angular breathing exercises. The program will be performed 3-4 times per week for 12 weeks, with gradual progression in intensity and duration. The control group will receive standard care without a structured exercise program.
Outcome measures will be assessed at baseline, immediately after the 12-week intervention, and at 3-month and 6-month follow-up periods. Primary outcomes include Cobb angle measured via radiographs, angle of trunk rotation assessed using a scoliometer, inspiratory capacity measured using spirometry, and spinal appearance evaluated using the Spinal Appearance Questionnaire. Secondary outcomes include quality of life assessed using the Scoliosis Research Society-22 questionnaire.
Blinding will be applied at the level of outcome assessors to reduce measurement bias. Statistical analysis will be conducted to compare within-group and between-group differences over time.
The results of this study are expected to provide evidence on the effectiveness of a combined exercise approach targeting both biomechanical and respiratory components of scoliosis. This may support the development of comprehensive rehabilitation protocols for adolescents with idiopathic scoliosis.
