Scapula; Deformity, Acquired

This randomized controlled trial aims to investigate the effects of Schroth exercises on scapular muscle activation in children with thoracic hyperkyphosis. A total of 56 participants will be randomly assigned to either the Schroth exercise group or the control group receiving postural education. The intervention group will complete an 8-week supervised Schroth program focusing on three-dimensional correction, rotational breathing, and postural awareness. Primary outcome is scapular muscle activation measured by surface EMG. Secondary outcomes include muscle strength, scapular endurance, kyphotic appearance, posture, and pain. The results will guide clinical management and preventive strategies for children with postural thoracic hyperkyphosis.
