Abstract:
ObjectiveTo observe the characteristic of reaction times (RTs) in the brain injury children.Methods65 children with brain injury, including 50 cerebral palsy (CP) cases, 13 brain trauma (BT) cases and 2 other cases, were selected as the experimental group, and 29 age-matched normal children as the control group. Children of two groups were tested by the eye-hand visual reaction times (VRTs), and children of the experimental group were also tested with Wechsler preschool and primary scale of intelligence (WPPSI), Wechsler intelligence scale for children (WISC-R) and comprehensive function assessment.ResultsThe VRTs of the experimental group children was significantly slower than that of the control group (P<0.01). There was no significant difference in VRTs test between CP and BT children (P>0.05). The motor time of VRTs of the severe subjects in the experimental group was significantly slower than that of moderate and light subjects (P<0.01). There was a negative correlation between VRTs and the scores of IQ, PIQ and the comprehensive function assessment.ConclusionThe attention and the motor speed of muscles are abnormal in children with brain injury.
