Abstract：This paper introduces Professor YU Haibo's clinical experience in treating pediatric tic disorders from the perspective of spleen and kidney. Professor YU posits that the disease is located in the brain， with symptoms manifesting in the sinews， while the root cause lies in the spleen and kidney. The core pathogenesis is identified as deficiency of spleen-kidney，internal disturbance of wind-phlegm，and loss of control of the spirit. Accordingly，the therapeutic principle of "invigorating the spleen and nourishing the kidney，regulating the spirit and arresting spasms" is established. In clinical practice，treatment of the spleen-invigorating and kidney-nourishing three-needle acupoint group serves as the core approach. Acupoints are selected at three levels corresponding to deficiency of spleen-kidney， internal disturbance of wind-phlegm，and loss of control of the spirit，respectively. The treatment integrates distinctive techniques such as abdominal and back pricking， flying needle rapid insertion， and three-spirit harmonization， achieving good therapeutic efficacy.
