The control group will perform the structured three-dimensional scoliosis exercise, core stabilization, and balance exercise with conventional methods at the clinic and home setting for twenty-four weeks. In the clinical setting, patients will perform their exercise for 2 days a week for 12 weeks, 1 day a week for the next 12 weeks, under the supervision of a physiotherapist. Patients will be asked to perform their exercises as a home exercise program on the remaining days (home exercise program 3 days a week for the first 12 weeks, 4 days a week after week 12).

The Rehabilitative Game-Based Exercise group will perform the structured three-dimensional scoliosis exercise with conventional methods similar to the control group. Differently, technology-based systems (BeCure Systems) will be used in the implementation of core stabilization and balance exercises. Patients will be asked to perform their exercises as a home exercise program on the remaining days (home exercise program 3 days a week for the first 12 weeks, 4 days a week after week 12).

Structured scoliosis exercises will be prescribed by the physiotherapist according to the severity of the curvature and cosmetics of the individuals. In a one session period, 5-minute warm-up and cool-down periods, 20 minutes of scoliosis exercises, 10 minutes of core stabilization exercises and 10 minutes of balance training will be applied. The exercises will start from an easy level and the level of difficulty will be gradually increased. The assessments will be evaluated in three stages: at the beginning of treatment, at the third month of treatment and at the end of treatment (sixth month).

In the treatment of scoliosis, the Cobb angle is considered the most important outcome for the evaluation of treatment efficacy. The Cobb angle is measured from anteroposterior graphs taken during standing. Measurements will be taken by a blinded assessor via SurgiMap web application to eliminate individual errors. Measurements will be made from radiographs taken at the beginning and sixth month of treatment because of the radiation exposure.

POTSI is a method that makes it possible to evaluate the trunk asymmetry of an individual with AIS from the posterior and objectively scores the cosmetic effect. It is based on certain calculations performed on a posterior photograph of the individual. The score calculated in POTSI analysis consists of the sum of 6 indices. In order to prevent possible calculation errors and standardize the measurements, the cases will be evaluated with a mobile application named POTSIApp.

WRVAS is a scale that scores the severity of curvature by focusing on the person's perception of posture. It is divided into 7 parameters including body curvature, rib prominence, lumbar prominence, head-rib-pelvis positional relationship, head-pelvis relationship, shoulder level and scapula rotation. A high score means that the perceived deformity is high.

One foot is lifted so that it does not touch the support leg, eyes are open at the beginning. The eyes are fixed in the direction of the head, the patient is asked to close his/her eyes and is expected to maintain his/her balance for 30 seconds. If the lifted leg touches the support leg, if the foot touches the floor, if there is bouncing or jumping, or if anything in the environment is touched for support, a balance disorder is considered.
