Among the children whose first treatment department was the Department of Rehabilitation，the number and the ratio of patients whose admission condition was difficult or severe showed an increasing trend（P< 0.001）. The total average length of hospital stay was 31.90±19.29 days， which declined（P< 0.001）.A total of 681 diseases were involved，and among the top 3 diseases，the number of cases of developmental delay（24.72%） showed an increasing trend，while the ratio had no significant change； the number and ratio of cerebral palsy（20.57%） showed a decreasing trend，and the number and ratio of traumatic brain injury（9.07%） showed an increasing trend（P< 0.05）. Conclusion    Many kinds of diseases are involved and the spectrum of diseases has changed in the Department of Rehabilitation during the recent9 years.The children with developmental delay，cerebral palsy，traumatic brain injury and other functional disorders are the main service subjects，and the rehabilitationdepartment of tertiary hospitals should focus on managing difficult and severe diseases.
