Purpose: This study was planned to inverstigate prenatal and perinatal factors influencing the development of cerebral palsy (C.P.) twins and to evaluate the possible causes of the C.P. in twins.
Method: Sixteen twin C.P. Children were evaluted at Department of Rehabilitation Medicine, St. Mary's Hospital, The Catholic University of Korea, School of Medicine, between March 1991 and July 1995.
Result: 1) 9(57%) children were low birth weight below 2550g at birth. 2) 11(69%) Children had had prematrity less than 36 weeks at birth 3) First baby group had more predominent incidence of CP than second baby group. 4) 10(63%) children were monozygotic twins. 5) Distributions of CP type were spastic diparesis(44%), spastic quadrioaresis(37%), and spastic hemiparesis(19%). 6) Fate of co-twin were CP/CP(50%), CP/stillborn(25%), CP/normal(19%), and CP/dead(6%). 7) Radiologic findings were periventricular leukomalaica(4 cases), brain atrophy(4 cases), porencephalic cyst (2 cases), cerebellar degeneration (1 case)
Conclusion: The data obtained in this study would be helpful for identifying and assessing the children with CP in twin pregnancy.

Analysis of spastic walking in CP by means of agonist-antagonist EMG ratio method
T. Akiyama, H.Nakano, S.Inoguti (Nagasaki University, Nagasaki, Japan)
(Purpose) To analyze reciprocal muscular activities in one walking cycle of spastic-type cerebral palsy(CP) children using the agomst-antagomst EMG ratiogram and correlationgram.
(Subjects and Method) The subjects were 6 spastic CP children of age 3-7 and 3 normal children of age 3-6. Myoelectric activities of tibialis anterior (TA) and triceps surae (TS) were evoked. The respective maximum value was scored as 100% to seek the relative ratio.
(Results) Compared to normal children, CP children showed irregular activities of the agohist-antagonist muscles and various correlationgrams (dominant extensor, dominant flexor). In severe spastic CP, pathologic co-contraction was remarkable although the TA phase was existent, and piston-like movement was observed on the line of TA/TS ratio=l.
