Scoliosis can be defined as a 3-dimensional deformity in which the lateral deviation and rotation of the vertebrae occur, as well as changes in the physiological curves of the spine. The gold standard criterion is that the Cobb angle, which determines the lateral deviation of the spine in the frontal plane, is greater than 10°.

Postural control and balance occur as a result of the integration of many sensory information. It is thought that postural control and balance in Adolescent Idiopathic Scoliosis (AIS) patients are adversely affected by biomechanical changes in sensory input, central integration, weight transfer mechanism and the structure of the medulla spinalis. In addition to these, vestibular disorders and proprioceptive losses may have an effect on balance.

Decline in balance reduces the quality of life of individuals with AIS. In addition, exercise has an important place in the treatment of individuals with AIS. In order to get more efficiency from the exercises, it is necessary to improve the balance.

The aim of this study is to evaluate the changes in balance, proprioception, and knee muscle strength of patients, to determine the place of balance exercises in the treatment of individuals with AIS, and to investigate the effect of core stabilization exercises on balance and proprioception in patients with AIS.

Inclusion Criteria:

• Diagnosed with AIS between the ages of 10-18
• Cobb angle is between 10-40 degrees
• The child's and family's consent to participate in the study
• The child does not receive any other treatment that will affect his scoliosis

Exclusion Criteria:

• Surgical operation in the last 3 months
• Presence of an orthopedic, neurological, systemic disease that will prevent him from exercising
• Having mental, communicative and behavioral disorders that may cause problems understanding commands and questions or performing exercises
• Exercising 3 or more days a week.
