Method
Twenty children with mild spastic diplegic cerebral palsy and fourteen normal children over 7 years old participated in this study. The foot was divided into 7 portions and then foot contact area, pressure of each foot portion and pathway of center of pressure (COP) were measured and analyzed by F-scan system (Tekscan Inc., USA)

Results
In children with cerebral palsy, first metatarsal area (MET1) showed the highest relative impulse followed by MET2/3, hindfoot and hallux. Relative impulse of hallux, MET1 and medial midfoot were significantly higher in cerebral palsied than in normal children, while that of hindfoot was significantly lower in cerebral palsied than in normal children. Anteroposterior ratio of COP and gait velocity were significantly lower in cerebral palsied than in normal children.

Conclusion
The characteristics of foot pressure distribution and the pathway of COP in children with mild spastic diplegic cerebral palsy were identified by quantitative analysis by F-scan system. Foot scan could be used for evaluating the foot pathology in children with cerebral palsy during gait. (J Korean Acad Rehab Med 2003; 27: 33-37)
