Brief summary

Trunk rotation and distortion of the rib cage, which are common in patients with adolescent idiopathic scoliosis, result in abnormal configuration of the diaphragm and intercostal muscles. This reduces the capacity of the respiratory muscles to produce force, and results in respiratory muscle weakness. The diaphragm, which is the major respiratory muscle, is also a component of the core muscles responsible for postural stability. Therefore, diaphragm muscle weakness results in deterioration of postural stability. Our aim in this study is to investigate the effect of inspiratory muscle training added to the routine scoliosis exercise program on postural stability and posture perception.

Interventions

OTHERConventional Scoliosis Exercise Program

Program will include breathing exercises, spinal stabilization and strengthening exercises, posture exercises and stretching execises.

OTHERInspiratory Muscle Training

Threshold IMT device will be used for the training. Training intensity will set at 30% of the maximum inspiratory pressure.

Design outcomes

Primary

Measure	Time frame
Change from baseline postural stability test score in Biodex Balance System SD at 8 weeks	8 weeks
Change from baseline limits of stability test score in Biodex Balance System SD at 8 weeks	8 weeks

Secondary

Measure	Time frame	Description
Change from baseline Walter Reed Visual Assessment Scale at 8 weeks	8 weeks	Walter Reed Visual Assessment Scale evaluates posture perception. It consists of a visual test including seven items that deal with various aspects of the deformity. Each question has a set of five figures that represent degrees of severity of the deformity: spinal deformity, rib prominence, lumbar prominence, thoracic deformity, trunk imbalance, shoulder asymmetry and scapular asymmetry.
Change from baseline maximum inspiratory pressure (MIP) at 8 weeks	8 weeks	—
Change from baseline maximum expiratory pressure (MEP) at 8 weeks	8 weeks	—
Change from baseline angle of trunk rotation at 8 weeks.	8 weeks	Angle of trunk rotation will be evaluated using Bunnell scoliometer in forward bending position
