The vertebral column is a structure that transfers the weight of the head and torso to the lower extremity, provides trunk movements and protects the spinal cord.A three dimensional deformity involving lateral flexion of the vertebrae in the frontal plane at 10 ° and above, including axial rotation and physiologic flexion (hypokyphosis) components in the sagittal plane, is defined as scoliosis. Adolescent idiopathic scoliosis (AIS) is a type of idiopathic scoliosis that occurs in the period from the onset of puberty (up to 10 years) until the closure of growth plates.

Scoliosis is caused by postural, balance and neuromotor disorders as a primary cause of impaired sensory integrity, proprioceptive feedback deficits, secondary lung problems, organ disorders and pain. Children with adolescent idiopathic scoliosis have inadequate respiratory function. At the same time, these children show muscle weakness in certain parts of the body.

The aim of this study is to compare young adolescents with scoliosis with their healthy peers and examine whether respiratory muscle strength, peripheral muscle strength and postural control are affected.

Inclusion Criteria:

• Individuals agreeing to participate in the study
• In the age range of 10-20
• Patients with scoliosis with a Cobb angle of 15-40 degrees measured on X-Ray

Exclusion Criteria:

• Surgical operation in the last 3 months
• Having mental, communicative and behavioral disorders that may cause problems understanding commands and questions or performing exercises.

It was calculated that at least 36 patients in total, 18 patients in the scoliosis and healthy groups, should be included in the study.
