Objective To find the development structure of cerebral palsy by Gesell Development Scale and improvement after the treatment. Methods Cerebral palsy (CP) children had Gesell Development Scales test before and after treatment,and a gross motor function classfication after treatment. Results A total of 105 children had the tests,spastic CP was predominant (74/105,70.48%),dyskinetic CP secondly(24/105,22.86%).The development quotient of CP was at the low-edge level,and gross motor area was the lowest(56.22±16.64).The development structure of the CP subtypes was different,gross motor area in spastic diplegia (51.92±10.18),fine motor area in hemiplegia(66.07±25.90),gross and fine motor areas in the dyskinetic children(43.64±14.64,47.07±19.27) were fell most.After the treatment,the development age was improved(P<0.05);development quotient of gross motor and adaption to other subject areas had differences than before.And the higher the GMFCS was,the lower DA and DQ were,children had less improvement(P<0.05). Conclusion Gross motor retardation was the core symptom of CP,the intelligence structure of CP subtypes was different.After the treatment,the gross motor area had less improvement,and the rate of the improvement had a correlation with GMFCS.In the clinical work,Gesell Development Scales test should be had at regular intervals.
