title: Children show decreased dynamic balance after mild traumatic brain injury.
abstract: OBJECTIVE
  To compare the balance skills of children after mild traumatic brain injury (TBI) with that of noninjured children matched for age, sex, and premorbid level of physical activity.
  
  
  METHODS
  Cohort study.
  
  
  METHODS
  Pediatric trauma center.
  
  
  METHODS
  Thirty-eight children aged 7 to 16 years (mean, 12.2+/-2.8 y) were recruited in each group. Children with mild TBI had a mean Glasgow Coma Scale score of 14.8 and were considered normal on a neurologic assessment at hospital discharge. Noninjured children were friends of those with mild TBI.
  
  
  METHODS
  Assessments of balance were conducted at 1, 4, and 12 weeks after mild TBI and at corresponding time intervals for the controls.
  
  
  METHODS
  The balance subtest of the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP), the Pediatric Clinical Test of Sensory Interaction for Balance (P-CTSIB), and the Postural Stress Test (PST) were used.
  
  
  RESULTS
  Over the time interval of the study, analyses of variance revealed that children with mild TBI performed significantly worse than the noninjured group on the BOTMP balance subtest (P<.001) and on the PST (P=.031), as well as on the eyes-closed conditions in the P-CTSIB tandem position (P=.05).
  
  
  CONCLUSIONS
  Children with a mild TBI still showed balance deficits at 12 weeks postinjury. These deficits should be taken into consideration when planning a return to physical activities, particularly to those that require subtle balance skills.
