Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to assess the immediate effects of a self-corrective exercise on muscle activity and spinal alignment in adolescents with idiopathic scoliosis. Eligible participants will undergo clinical assessments of spine deviation and surface electromyography (EMG) before and after a single session of guided self-controled and self-corrective exercise. The findings may help inform rehabilitation strategies for adolescent idiopathic scoliosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Adolescent idiopathic scoliosis (AIS) involves three-dimensional spinal deformity and asymmetric paraspinal muscle activation. Scoliosis-specific, self-corrective exercises are widely used in conservative care, but their immediate neuromuscular and postural effects after a single guided session remain insufficiently characterized.

This prospective pre-post study will enroll adolescents with radiographically confirmed AIS for one clinic visit. After eligibility confirmation and consent/assent, participants will complete baseline assessments, perform a standardized, therapist-guided self-controlled, self-corrective exercise tailored to curve pattern, and then repeat the same assessments immediately afterward. The protocol emphasizes axial elongation, active self-correction delivered within a brief supervised session.

The primary purpose is to quantify immediate changes in spinal alignment and paraspinal muscle activity to explore potential mechanisms of action and inform refinement of rehabilitation strategies for AIS. Feasibility and tolerability will be monitored during the single visit. No additional imaging is required beyond existing clinical records. Findings will be disseminated through scientific channels to guide future conservative management and hypothesis generation for subsequent controlled trials.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control Exercise

Participants perform a standard exercise that does not include self-correction elements. This serves as the control condition for comparison.
