Abstract:

BACKGROUND: The gait abnormalities in the children with spastic cerebral palsy are common, and how to improve the gait has become the focus of the rehabilitation.
OBJECTIVE: To investigate the temporal and spatial parameters and the action of the pelvic during gait in children of 4-6 years old with spastic diplegic cerebral palsy. 
METHODS: Three-dimensional gait analysis was used to get the temporal and spatial parameters and the action date of the pelvic during gait. Sixty children were involved: 20 children who can walk more than three meters by themself as independent walking group; 20 children who cannot walk by themself or walk the distance less than 3 meters, but in the help of one hand may walk more than 3 meters as assist walking group; at the same time to select the match age of 20 healthy children as normal control group.
RESULTS AND CONCLUSION: ①As for the temporal and spatial parameters, the step length and stride length of stance phase and double support phase in the normal control group was shorter than those in the independent walking group and assist walking group (P < 0.05); and the step length and stride length in the assist walking group were more longer than those in the independent walking group (P < 0.05); no significant differences were observed in step width between three groups (P > 0.05). ②As for the action of the pelvic, the total excursion of pelvic obliquity in the independent walking group and assist walking group was larger than that in the normal control group (P < 0.05) and the total excursion of pelvic obliquity in the assist walking group was larger than that in the independent walking group (P < 0.05); the anterior tilt of each phase of the walk cycle in the independent walking group and assist walking group was obvious than that in the normal control group (P < 0.05) and the assist walking group was more obvious than independent walking group (P < 0.05); the total excursion of pelvic rotation in the independent walking group and assist walking group was significantly larger than that in the normal control group (P < 0.05) and the assist walking group was more larger than independent walking group (P < 0.05). The temporal and spatial parameters and the action of the pelvic during gait in children of 4-6 years old with spastic diplegic cerebral palsy are different from healthy children. The poorer the walking ability, the more obvious the abnormality was. The excessive anteversion of pelvic may be the most important factor for walking ability.
