Kyphosis study form consisting of clinical and radiological measurements of patients aged 12-18 years who applied to the outpatient clinic with spine deformity will be filled in detail.

Adolescents aged 12-18 years presenting to the scoliosis outpatient clinic will undergo a standardized physical examination. Posture will be assessed in standing position from both anterior and lateral views in front of a posture chart. In patients where thoracic kyphosis is clinically suspected, a standing orthoroentgenogram (whole-spine radiograph) will be requested. On these radiographs, thoracic kyphosis angles will be measured to confirm the diagnosis and establish baseline values. Clinical and radiological data will be recorded in detail before study group allocation.

Thoracic kyphosis angle will also be assessed using a bubble inclinometer during physical examination. The participant will stand in a relaxed upright position, and the inclinometer will be placed over the spinous processes from T3 to T12 to measure the sagittal alignment of the thoracic spine. Three consecutive measurements will be taken for each participant, and the mean value will be recorded for analysis. This provides a reliable clinical estimate of thoracic kyphosis in addition to radiographic assessment.

The Biering-Sorensen test is a standardized clinical assessment used to evaluate the isometric endurance of the trunk extensor muscles. During the test, the participant lies prone on an examination table with the upper edge of the iliac crests aligned with the edge of the table. The lower body (pelvis, knees, and ankles) is stabilized using straps or manual fixation. The upper body is extended horizontally beyond the edge of the table, with the arms crossed over the chest. The participant is instructed to maintain the unsupported horizontal trunk position for as long as possible without assistance. The outcome is recorded as the duration, in seconds, that the participant can hold the trunk in a straight horizontal alignment before fatigue, deviation from the position, or voluntary termination occurs.
