The purpose of this study was to collect basic data in the gait pattern of the spastic diplegia children for rehabilitation program, and to examine the differences in the gait pattern against normal children group. Three-dimentional motion analysis technique was employed to compare the gait pattern of five children with diplegic cerebral palsy against a group of 10 normal children of the same age. The following conculsions were drawn from the results: Spastic diplegia revealed asymmetrical gait pattern in which the step length of the stride which was a result of the effort to minimize the loading on the leg by shortening the swing phase of the leg. C.P spastic diplegia scored lower phase ratios, lesser cadence and walking velocity with lower gait stability and function. More anterior tilting of the pelvis was observed throughout the gait cycle. C.P. children showed more hip and knee flexion during the stance phase. The main problem in C.P children originated from the insufficient dorsiflexion of the foot during the swing phase. Therefore, C.P children showed difficulty with foot clearance in the swing phase. Usually, this compensated for by using excessive hip adduction and external rotation in conjunction with trunk elevation flexion and as well as increased vertical displacement of the center of mass. C.P spastic diplegia revealed foot flat and forefoot initial contact pattern. The findings were as follows: 1. The walking velocity and stride length decreased in the spastic diplegia group. 2. The proportion ratios of the stance phase tended to increase with spastic diplegia. 3. The range of the hip joint motion with C.P increased while knee flexion angle during the swing phase increased. 4. The plantar flexion angle of the ankle also increased through the gait cycle. 5. Hip adduction and external rotation with C.P increased through the gait cycle.
