Background: Core stabilization exercises are a key component of exercises for the conservative treatment of adolescent idiopathic scoliosis (AIS). Objectives: To evaluate the effectiveness of two different home-based exercise instruction methods (leaflets versus video materials) for children with AIS performing core stabilization exercises. Design: A retrospective study. Methods: Pediatric outpatients diagnosed with AIS were assigned to either a leaflet group or a YouTube video group. They were instructed to perform core stabilization exercises at home daily, completing three sets per day for six months. Pre- and post-exercise (6 months) evaluations included X-rays to measure the Cobb angle and the degree of vertebral rotation. Additionally, endurance in maintaining the Superman and Bird-dog positions was assessed. Results: After 6 months of intervention, the leaflet and YouTube groups showed no significant differences regarding Cobb angle, rotational degree, or endurance in the Bird-Dog and Superman positions. However, within-group comparisons before and after the 6-month exercise period showed a significant improvement in Cobb angle in the leaflet group. If exercise leaflets are effectively utilised, they could facilitate the implementation of core stabilization exercises in children with AIS, potentially improving their prognosis. Conclusion: Providing exercise instruction via a leaflet may be more effective than using a YouTube video in facilitating adherence to core stabilization exercises and improving spinal alignment in children with AIS.
