Immediate Effects of Self-Corrective Training in Adolescent Idiopathic Scoliosis: A Nested Study

This nested study was conducted within a broader adolescent idiopathic scoliosis research protocol approved under IRB UW24-747. It evaluated immediate within-session changes in bilateral muscle-activation asymmetry and posterior trunk-marker alignment after one session of therapist-guided, individualized self-corrective posture training. All participants completed the same fixed sequence during one visit; there was no randomized or separate parallel control group.

Inclusion Criteria: * Aged 11 to 19 years * Diagnosis of adolescent idiopathic scoliosis Exclusion Criteria: * Scoliosis of non-idiopathic origin * Previous spinal surgery * History of spinal trauma, such as fracture or motor vehicle accident * Metal implant, such as a pacemaker * Cognitive, psychiatric, behavioral, or communication difficulty preventing understanding of instructions or completion of required movements * Skin condition or open wound affecting electrode placement
