This clinical study includes examining trunk proprioception and pelvis orientation in all three planes, pain, flexibility, health-related quality of life, perception of cosmetic deformity, dynamic balance, and the effectiveness of different exercise training in individuals aged 10-18 years with a diagnosis of adolescent idiopathic scoliosis and who have PSSE indication.~As the control group; healthy peers with the same characteristics as the exercise groups will be included and they have a negative result of Adam's forward bending test, they do not have any postural disorders.~As a result of the randomization to be applied to the individuals, they will be divided into two groups: PSSE exercise group and vestibular exercise group (vestibular exercises added to PSSE exercises).~Initial assessments will be given to all individuals. Exercise training groups will participate in a 45-minute exercise session with the supervisor, twice a week for 12 weeks. Before exercise training, individuals and their parents will be informed about education and daily life activities.~Apart from the exercises performed under the supervision of a physiotherapist, individuals will be given a home exercise program, and the family and the individual will be asked to keep a diary to evaluate their compliance with the exercise, and the exercise compliance will be evaluated with a phone call every week.~When the exercise training is completed, the training groups will be evaluated as post-training assessments.~In the statistical analysis of data; the values of the control group will be used as normative and will be compared with the data of individuals with scoliosis. The data of the training groups before and after the training program will be compared, and the data of the different exercise groups will be compared with each other.
Aims of this clinical research:~To investigate trunk proprioception in all three planes in individuals with adolescent idiopathic scoliosis (AIS),~To investigate the pelvis orientation sense in all three planes in individuals with adolescent idiopathic scoliosis,~To investigate whether trunk proprioception and pelvis orientation sense are improved with Physiotherapy Scoliosis Specific Exercises (PSSE) in AIS,~To investigate whether trunk proprioception and pelvis orientation sense are improved with vestibular exercise training to be added to PSSE exercises in AIS,~Comparison of the effects of different exercise training on trunk proprioception and pelvis orientation sense in AIS~To examine the parameters that may be associated with the improvement of trunk proprioception of different exercise training (health-related quality of life, perception of cosmetic deformity, scoliosis-related clinical features such as Cobb angle, axial trunk rotation, curve type, etc.).
