简要总结
Adolescence is a critical period for spinal growth, and progression of thoracic hyperkyphosis may lead to pain, weak trunk muscles, sleep disturbances, and reduced quality of life. This study aims to investigate the effects of three-dimensional exercise program based on the Schroth Method on trunk muscle endurance, thoracic kyphosis angle, pain, sleep quality and quality of life in adolescents aged 12-18 years with hyperkyphosis.
详细描述
Childhood and adolescence are critical developmental stages characterized by rapid spinal growth, as well as the formation of postural habits and the musculoskeletal system. During this process, various spinal deformities may arise due to neuromuscular, structural, postural, or functional causes, and if not addressed in a timely manner, they can lead to permanent postural abnormalities carried into adulthood.
Thoracic kyphosis is the physiologically present forward curvature of the spine in the sagittal plane and is generally considered normal within the range of 20°-45°. However, when this angle exceeds 45°, it is referred to as hyperkyphosis. Hyperkyphosis can develop due to many different causes, such as postural abnormalities, muscle imbalances, and vertebral developmental anomalies. This deformity can become more pronounced, especially during adolescence when growth spurts occur.
The progression of hyperkyphosis that emerges during the developmental period can lead to serious clinical consequences in children and adolescents, including aesthetic concerns, weak trunk muscles, pain around the spine, sleep disorders, and a decline in quality of life. Timely diagnosis and effective rehabilitation of adolescent hyperkyphosis are critical in controlling the progression of the deformity and preventing functional loss.
The literature reports that exercise-based approaches are effective in treating kyphosis in this age group. Schroth exercises, in particular, are a specialized physical therapy protocol used in the treatment of 3-dimensional scoliosis and kyphosis. They offer individualized, breathing-integrated postural correction techniques that target interplanar asymmetry of the spine. With this approach, patients are taught positioning to actively correct spinal segments, proprioceptive awareness, and breathing control. The Schroth method aims not only at passive posture correction but also at reestablishing muscle balance and maintaining correct posture in daily life.
In this context, Schroth exercises, which specifically target 3-dimensional spinal correction, are among the interventions frequently recommended in the literature.

研究组 & 干预措施
Three-Dimensional Exercise Group
Adolescents aged 12 to 18 years with a diagnosis of kyphosis will undergo a supervised three-dimensional exercise program based on the Schroth Method. The intervention is specifically tailored for adolescents with kyphosis and aims to improve postural alignment, increase spinal mobility, enhance back extensor muscle endurance, and restore trunk muscle balance. The program consists of 10 outpatient sessions (approximately 60 minutes each), delivered by a physiotherapist trained in the Schroth Method.
Exercises include postural correction, rotational angular breathing techniques, stabilization strategies, and individualized corrective postures adapted to the patient's spinal deformity pattern. After completing the supervised sessions, participants will be instructed to continue performing the Schroth exercises as a home-based program for the remainder of the study period, with adherence monitored through exercise logs and outpatient follow-up.

结局指标
主要结局
Thoracic Kyphosis Angle (Inclinometer Measurement)
时间窗: Assessments will be performed at baseline (one day before the exercise program), at 1 month and at 3 months after the initiation of exercises.
Thoracic sagittal alignment will be assessed using a bubble inclinometer placed over the spinous processes from T3 to T12 while the participant stands in a relaxed upright position. Three consecutive measurements will be performed for each participant, and the mean value will be recorded for analysis. This clinical method provides a reliable and non-invasive estimate of thoracic kyphosis angle in adolescents.
Biering-Sorensen Test (Back Extensor Endurance Test)
时间窗: Assessments will be performed at baseline (one day before the exercise program ), at 1 month and at 3 months after the initiation of exercises.
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.
