The purpose of this study was to collect basic data on the gait pattern o f the flexor dominance diplegia children for rehabilitation program, and t o examine closely comparative analysis the difference in the gait pattern against normal children group. This study was to analyze the gait pattern o f a child with flexor dominance diplegic cerebral palsy(CP) and a group of 10 normal children of the same age were selected as the control group for comparison by using the three-dimensional motion analysis technique. Flexor dominance diplegia revealed and asymmetrical gait pattern in which the step length of the foot which was a result of the effort to minimize loading on the leg by shortening the swing phase of the leg. Flexor dominance diplegia scored decrease phase ratios, cadence and walking velocity to the normal group with lower gait stability and function. A anterior tilt of the pelvis was observed throughout the gait cycle. More hip and knee flexion than normal group was observed and demonstrated flexion of hip and knee in the stance phase. The main problem in CP children originated from the insufficient dorsiflexion of the foot during the swing phase. Therefore, CP children has 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. CP flexor dominance diplegia revealed foot flat and forefoot initial contact pattern.
