In children with cerebral palsy, secondary problems lead to hip dislocation and scoliosis. But There is no definite evidence for the dislocation of hip and scoliosis. The investigators want to verify evidence of scoliosis and dislocation of hip.
Observation cohort study. The investigators will measure for finding evidence by checking the x-ray photograph, hip adductor muscles pressure test and electromyography(EMG test) test of hip adductor and spine muscles

RECRUITINGhip adductor and spin muscles electromyography(EMG) test
Use EMG to check the activity of the hip adductor and spine muscles of participants. This figures will give investigators a look at the association with a hip dislocation.
Time frame: once at study, when patient enrolled
Whole spine AP and total Hip AP X-ray photograph
Whole spine and total Hip joint are checked with X-ray photograph. and investigators will check the progress of hip dislocation and spinal scoliosis.
Time frame: once at study, when patient enrolled and after once every six months for three years
hip adductor muscles pressure meter test
Pressures of hip adductors muscles are measured from pressure meter. and This figures will give investigators a look at the association with a hip dislocation.
Time frame: once at study, when patient enrolled
