This study is a single-blind, two-arm parallel-group randomized controlled trial designed to evaluate the effects of core stabilization exercises combined with rotational angular breathing exercises on adolescents with idiopathic scoliosis. Participants aged 10-18 years with a Cobb angle between 10° and 25° will be randomly assigned to either an experimental group receiving a structured exercise program or a control group receiving standard care.
The intervention will be conducted over 12 weeks, with outcomes assessed at baseline, post-intervention, and follow-up periods. Primary outcomes include Cobb angle, angle of trunk rotation, inspiratory capacity, and spinal appearance. The study aims to determine whether the combined exercise approach is more effective than standard care in improving spinal alignment, respiratory function, and physical appearance.
Adolescents aged 10-17 years
Both male and female participants
Diagnosed cases of idiopathic scoliosis
Cobb's angle between 10° and 25°
Previous spinal surgery
Significant neuromuscular disorders (e.g, muscular dystrophy, cerebral palsy)
Other medical conditions affecting participation (e.g, respiratory or cardiac)
Any contraindication to exercise program
Parallel
Core Stabilization Exercises
Other interventionCore stabilization exercises: planks, bridges, bird dog, and dead bug Rotational angular breathing exercises: emphasizing thoracic expansion, asymmetric rib cage mobility, and postural correction through controlled inhalation and prolonged exhalation All exercises will be performed under supervised conditions initially, with emphasis on neuromuscular control, spinal stability, and coordinated breathing. Each session will last 40 minutes, including: 3 sessions per week 12-week intervention period 5 minutes warm-up 25 minutes core stabilization exercises 10 minutes rotational angular breathing exercises • Cool-down and postural awareness exercises
Standard Care (in control arm)
Other interventionParticipants in the control group will receive conventional physiotherapy management routinely used for idiopathic scoliosis. The intervention will focus on posture correction, spinal mobility, flexibility, general strengthening, and breathing awareness exercises without specialized core stabilization or rotational angular breathing techniques. The program will include: Warm-up exercises Stretching exercises for trunk and lower limb muscles Spinal mobility exercises Basic abdominal and back strengthening exercises Postural correction and ergonomic education Diaphragmatic breathing and relaxation exercises Cool-down exercises Sessions will be supervised initially by a physiotherapist to ensure correct technique and safety. Frequency and Duration 3 sessions per week 12-week intervention period 40 minutes per session Session Structure 5 minutes warm-up 25 minutes conventional physiotherapy exercises 5 minutes breathing exercises 5 minutes cool-down and posture education
Cobb's angle
Cobb angle is a radiographic measure used to quantify the degree of spinal curvature in scoliosis. It is measured by identifying the most tilted vertebrae at the upper and lower ends of the curve on an anteroposterior spinal radiograph and calculating the angle between intersecting perpendicular lines drawn from these vertebrae. Time Frame: Baseline, 4 weeks, 8 weeks and 12 weeks
Trunk rotation
Angle of Trunk Rotation is assessed using a scoliometer during the Adam's Forward Bend Test. The device is placed over the spine at the point of maximum deformity to quantify axial trunk rotation and rib hump prominence. Time Frame: Baseline, 4 weeks, 8 weeks and 12 weeks
Inspiratory capacity
Inspiratory capacity is defined as the maximum volume of air that can be inhaled after a normal expiration. It is measured using spirometry with a calibrated spirometer to assess pulmonary function and thoracic expansion. Time Frame: Baseline, 4 weeks, 8 weeks and 12 weeks
Spinal appearance
The Spinal Appearance Questionnaire is a patient-reported outcome measure that evaluates the perception of spinal deformity and cosmetic appearance. It includes domains related to trunk asymmetry, curve perception, and self-image. Time Frame: Baseline, 4 weeks, 8 weeks and 12 weeks
