The purpose of this study was to investigate the effectiveness of two different exercises in adolescent idiopathic scoliosis. In total, 28 subjects with adolescent idiopathic scoliosis were randomly divided into two groups: Schroth (n = 14) and stabilization group (n = 14). The Schroth group received Schroth exercises in addition to traditional rehabilitation, and the stabilization group received core stabilization in addition to traditional rehabilitation for 10 weeks. The outcome measures were based on Cobb angle, angle of trunk rotation, spinal mobility, cosmetic trunk deformity, muscle strength, and quality of life.
Adolescent idiopathic scoliosis (AIS) is a progressive growth disease with unknown etiology, characterized by a three-dimensional deformity of the spine (frontal translation, sagittal modification, and torsion of the spinous processes on the concave side of the scoliotic curve on radiographs). In patients with AIS, in addition to curve progression there are many problems commonly occur such as; muscular imbalance, functional limitations, altered posture, gait deviations, reduced flexibility of the spine, back pain, negative physico-social, body image effects, and in severe cases pulmonary symptoms. The asymmetry of the trunk and pelvis are affected related to the shape and angle of scoliosis, and the weight distribution position changes depending on the shape and the Cobb angle of scoliosis. To deal with these complications and more, various treatment approaches have been proposed for AIS, including exercise, bracing, casting, traction, biofeedback, surgery, and simple observation to prevent, correct or halt the progression of the deformity. Conservative treatment methods including physiotherapy and bracing are accepted in Central Europe. In literature, exercises are recommended to decrease progression, to improve spine and thoracic cage flexibility, muscle strengths, and elasticity, to correct postural behavior, and neuro-motor control, spine stability. In general, traditional exercises (TE) including postural training, stretching, and strengthening exercises for spinal musculature, respiratory exercises have been used for many years for scoliosis. Except for the traditional exercises, there are several exercise concepts including Schroth, Side Shift, Dobomed methods... etc. Schroth exercises are asymmetric scoliosis-specific postural exercises that aim to improve the curve, function, posture, self-image, and pain. Schroth exercises target strength and endurance training of the back, abdominal, and leg muscles. Also one of the aim of Schroth exercises is to improve motor control of the posture by repeating corrective movements with progressively less feedback. Schroth exercises are the most studied scoliosis exercises but there are limited randomized controlled studies on Schroth exercises. Recently general physiotherapeutic exercises including, Core stabilization (CS) exercises, Pilates have been used in the conservative treatment of idiopathic scoliosis. CS exercises are described as therapy techniques that improve postural control, and functional stability through increasing neuromuscular control, the strength of trunk stabilization muscles, the endurance of postural muscles around the spine, the balance between pelvis and spine. However, limited studies are determining CS exercises' effect on patients with AIS. In a study CS exercises found to be more effective in reducing pain and rotational deformity than traditional exercises in the conservative rehabilitation of AIS. A recent systematic review showed that therapeutic exercise had been effective to reduce symptoms, Cobb's angle, trunk rotation, craniovertebral angle, and body asymmetries, and to improve muscular endurance, pulmonary function, and functional capacity of patients with AIS. Corrective, therapeutic exercises appear to have positive effects by improving function and reducing symptoms, as well as various angles and body asymmetries. However, further studies with better methodological quality are required to confirm these outcomes and detect the best therapeutic exercise intervention. And also there is a need for randomized controlled studies on different methods of exercise to choose the most effective exercise in clinical practice. There was no research compared to the effects of the Schroth method and CS exercises in patients with AIS. And also there was no research examining the effects of the Schroth method on peripheral muscle strengths. This study aimed to investigate the effects of the Schroth versus CS exercises in addition to traditional exercises, on Cobb angle, trunk rotation, peripheral muscle strengths, spine mobility, cosmetic deformity, and health-related quality of life in patients with AIS.
The Schroth approach consists of 3D scoliosis-specific exercises based on kinesthetic and sensorimotor principles. The goal of Schroth exercises is to teach patients to consciously maintain the correct posture in daily living activities in order to improve the curve, pain, and self-image. The treatment program consists of scoliotic posture correction and a breathing pattern with the help of proprioceptive and exteroceptive stimulations and mirror control. Traditional exercises program included strengthening back, abdominal, pelvis and shoulder girdle muscles and also muscles in the convex side of the curve, stretching exercises especially for the concave side of the curve, postural training, flexibility exercises for the spine, and breathing exercises. Schroth group received Schroth exercises in addition to traditional rehabilitation for 10 weeks. Patients received 30 sessions for 90 minutes at the clinic for ten-week treatment period.
Each exercise session consisted of a warm-up exercise, core stabilization exercise, and a cool-down exercise. The core stabilization exercise was designed with consideration of local, global muscle stability training, global muscle mobility training,and strengthening training of these core structures was carried out progressively advancing more difficult. Traditional exercises program included strengthening back, abdominal, pelvis and shoulder girdle muscles and also muscles in the convex side of the curve, stretching exercises especially for the concave side of the curve, postural training, flexibility exercises for the spine, and breathing exercises. The Stabilization group received Core stabilization in addition to traditional rehabilitation for 10 weeks. Patients received 30 sessions for 90 minutes at the clinic for ten-week treatment period.

Cobb's angle
Cobb's angles were measured on standard standing anterior-posterior spine radiograph and recorded as degrees. Cobb angle is considered the gold standard to evaluate the curve magnitude. The Cobb angle is the angle from a posterior-anterior full spine radiographs between the upper endplate of the upper-end vertebra of the largest curve and the lower endplate of the lower end vertebra from the largest curve.
Time frame: 10 week
Trunk rotation angles
-Trunk rotation angles Axial trunk rotations (ATR) were assessed with a scoliometer in Adam's forward bend test.
Time frame: 10 week
Muscle strength
Muscle strengths were assessed by a Biodex System 4-Pro dynamometer (Biodex, Inc., Shirley, New York). Upper extremity pattern strengths (flexion-abduction-external rotation / extension-adduction-internal rotation), and quadriceps, hamstring muscles strengths were assessed in both extremity. The outcome parameter was the peak torque (expressed in Nm) which was normalized to the participants' body weight (expressed in Nm/kg) in an effort to reduce inter-subject variability in raw scores of quantitative muscle tests.
Time frame: 10 week
Spinal mobility
Spinal mobility was assessed with a new computer-aided skin-surface device (The Spinal Mouse® System, Idiag, Fehraltorf, Switzerland). Spinal Mouse is an external non-invasive measurement method developed to evaluate the motility and shape of the spine in many planes. The Spinal Mouse has acceptable metrological properties to assess segmental and global thoracal and lumbar mobility. Measurements were performed between spinous process of C7 and the top of the anal crease (approximately S3). Maximal extension, maximal flexion and maximal left and right lateral flexion positions were performed. The analysis of spinal mobility in the sagittal (SAP - maximal extension to flexion) and the coronal (CRP - maximal left to right flexion) plane was evaluated.

Cosmetic trunk deformity
Walter Reed Visual Assessment Scale (WRVAS) was used to assess cosmetic deformity. The domains of WRVAS are body curve, rib prominence, flank prominence, head rib pelvis, head pelvis, shoulder level, and scapular rotation. Each domain generates a score from 1 (best deformity) to 5 (worst deformity). The total score is an average of these 7 domains.
Time frame: 10 week
SRS-22 Questionnaire
The SRS-22 questionnaire assesses the quality of life in scoliosis. It is a self-reported tools assessing self-image, function, pain, mental health with 5 questions each and satisfaction with care with 2 questions which are scored from 1 (best answer) to 5 (worst answer) each question. A total score is based on all 22 questions and an average of these 7 domains.
