　　Aim:Studies have revealed very limited data to learn about muscle architecture in children with cerebral palsy(CP).We aimed to investigate muscle thickness,fascicle length,and pennation angle of medial and lateral gastrocnemius,soleus,and tibialis anterior between Asian children with spastic CP and typically developing(TD)children.Method : Participants(age range,2-13y)were divided into three groups: hemiplegic CP(HCP)group(n=24),diplegic CP(DCP)group(n=24),and typically developing peers(TD)group(n=24).Muscle architecture was measured using ultrasound at rest.Clinical measures included gross motor function measure,modified Ashworth scale,and social life ability scale.Results:Muscle thickness of tibialis anterior and medial gastrocnemius in the affected calf of children with CP were smaller(p<0.05)than those of TD children,besides that lateral gastrocnemius and soleus fascicle length was smaller(p<0.05)in children with diplegic CP than in TD children.Fascicle length of the affected calf in children with CP was shorter(p<0.05)than that of TD children and the unaffected side of children with hemiplegic CP,except that lateral gastrocnemius fascicle length was similar between the two sides of children with hemiplegic CP.Pennation angle of medial gastrocnemius and soleus were larger(p<0.05)in the affected calf of children with hemiplegic CP than in TD children.Muscle thickness and fascicle length were positively correlated with social life ability scale scores in children with CP(r=0.316-0.488; p<0.05).Conclusion:Muscle thickness and fascicle length were decreased in the comparisons between affected and TD muscle and the affected and unaffected muscle across tibialis anterior,gastrocnemius,and soleus.Those changes may limit social life and indicate needs for strengthening the affected muscle.
