this is an observational and cross-sectional prevalence study. 10-18 years aged participants with adolescent idiopathic scoliosis were recruited in the study. Myofascial pain syndrome will be questioned to the participants. additionally, all participants will be evaluated using their findings for scoliosis and myofascial pain syndrome diagnostic criteria. Cobb angle, coronal balance, shoulder and pelvis asymmetry, sagittal spino-pelvic parameters of the spine (cervical lordosis, thoracic kyphosis, lumbar lordosis angles and sagittal vertical axis, sacral slop angle and pelvic incidence) will be measured.

This is an observational and cross-sectional prevalence study. Patients diagnosed with adolescent idiopathic scoliosis who applied to the Physical Medicine and Rehabilitation Clinic of Kanuni Sultan Süleyman Training and Research Hospital will be included in our study. These participants will be aged between 10-18 years. These patients will be evaluated using their findings for scoliosis and myofascial pain syndrome diagnostic criteria. Cobb angle, coronal balance, shoulder and pelvis asymmetry, sagittal spino-pelvic parameters of the spine (cervical lordosis, thoracic kyphosis, lumbar lordosis angles and sagittal vertical axis, sacral slop angle and pelvic incidence) will be measured. Diagnostic criteria of Myofascial Pain Syndrome; As the Major Criteria;

1. Regional pain complaint
2. Pain or sensory change reflected from trigger points to a specific area 3. Palpable taut band in accessible muscles

4. Extreme tenderness at one point along the taut band 5. Decreased range of motion that can be measured As for the Minor Criteria;

1. Complaint of clinical pain and/or sensory change on pressurized palpation of the trigger point
2. Local twitch response of the tender point on the taut band with palpation and needling 3. Reduction of pain by injection of the tender point or stretching of the muscle Five major and at least 1 minor criteria are required for the clinical diagnosis of myofascial pain syndrome.

Patients with a previous history of surgery for scoliosis and neuromuscular scoliosis were excluded from the study.
