In this study, the factors related to the motor recovery after VPS were analysed.Method Twenty-six patients were treated with VPS, and four factors, that are duration of symptoms, open lumbar puncture(LP) pressure, improvement after LP ,and motor recovery of twelve months after operation,were assessed. Results Twelve months after VPS, the better motor recovery after VPS was related to shorter duration of symptoms, higher open LP pressure, and symptom improvement after LP. Conclusion The patients with shorter duration of symptoms, higher open LP pressure, and symptom improvement after LP are often responsive to VPS. Key words: Normal pressure hydrocephalus; Ventriculoperitoneal shunting
