Back Muscle Function in Adolescents With Idiopathic Scoliosis

January 23, 2026 updated by: Gali Dar, University of Haifa

Back Muscle Function During Exercise With and Without Correction According to the "Schroth" Method in Adolescents With Scoliosis

The function and asymmetry of back muscles will be examined in different positions and with specific spinal corrections based on scoliosis pattern and according to the "Schroth method" in adolescents with idiopathic scoliosis.

Detailed Description

The study aim is to examine function and asymmetry of back muscles in different positions and with and without specific spinal corrections based on scoliosis pattern and according to "Schroth ethod" in adolescenet idiopathic scoliosis. The will include adolescents aged 10-14 years diagnosed on X-ray with idiopathic scoliosis of 15-400 Cobb angle. Participants will undergo an assessment that includes: demographic questionnaire, pain severity measured by the visual analog scale , quality of life questionnaire for patients with scoliosis (SRS-22), Adam's Forward Bend Test, spine rotation angle assessment using a scoliometer, leg length measurement, hip range of motion using goniometer, Risser sign, Coronal trunk balance and Sagittal vertical axis- according to X-ray, scoliosis classification.

Following examination, participants will perform three exercises that activate back muscles in three different positions: supine lying, side lying and standing. Each exercise will be performed twice: the first time without and the second time with specific corrections of the scoliosis. The exercises will be performed according to "Schroth" method implying that the corrections of the spine will be determined according to the scoliosis pattern and classification for the scoliosis (single / double, thoracic, lumbar etc.) and will be conducted via belts, cushions, and bars.

During each exercise, back muscles thickness will be examined and measured via portable diagnostic ultrasound. The muscles will be measured at T7 and L4 levels in resting and contracting positions. Back muscle function will be evaluated by calculating percentage of change between positions rest and contraction position.

Comparison between muscle function with and without correction and correlation of muscle function to quality of life and other morphological parameters will be assessed.
