Objective: To investigate the clinical efficacy of Liu’s Painless Scalp Acupuncture for Children in treating Attention Deficit Hyperactivity Disorder (ADHD). Methods: Sixty children diagnosed with ADHD who visited the Acupuncture and Rehabilitation departments of our hospital between January 2023 and June 2025 were selected. All children received Liu’s Painless Scalp Acupuncture for Children. The Conners Parent Rating Scale (CPRS) and the Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) were used to evaluate therapeutic effects before treatment and after 3 courses of treatment. Adverse events occurring during the treatment process were recorded to assess the safety of Liu’s Painless Scalp Acupuncture for Children. Results: After 3 courses of treatment, the scores on both the CPRS and SNAP-IV showed significant improvement, with statistically significant differences (P<0.05). Conclusion: Liu’s Painless Scalp Acupuncture for Children is a safe and effective treatment for ADHD. It significantly improves the core clinical symptoms of children with ADHD, notably enhancing attention and reducing hyperactive-impulsive symptoms.
