The utility of normative foot floor angle data in assessing toe-walking.

Initial heel contact is an important attribute of gait, and failure to complete the heel rocker reduces gait stability. One common goal in treating toe-walking is to restore heel strike and prevent or reduce early heel rise. Foot floor angle (FFA) is a measure of toe-walking that is valuable for quantifying foot orientation at initial contact when using ankle dorsiflexion angle alone is misleading. However, no age-standardized FFA norms exist for clinical evaluation. Our objectives were to: (1) obtain normative FFA in typically developing children; and (2) examine its utility in the example of toe-walking secondary to unilateral cerebral palsy. Gait kinematics were acquired and FFA trajectories computed for 80 typically developing children (4-18 years). They were also obtained retrospectively from 11 children with toe-walking secondary to unilateral cerebral palsy (4-10 years), before and after operative intervention, and compared to 40 age-matched, typically developing children. FFA at initial contact was significantly different (P<.001) between pre-surgery toe-walking (-14.7±9.7°; mean±standard deviation) and typical gait (18.7±2.8°). Following operative lengthening of the gastrocnemius-soleus complex on the affected side, FFA at initial contact (-0.9±5.3°) was significantly improved (P<.001). Furthermore, several cases were identified for which the sole use of ankle dorsiflexion angle to capture toe-walking is misleading. The assessment of FFA is a simple method for providing valuable quantitative information to clinicians regarding foot orientation during gait. The demonstrated limitations of using ankle dorsiflexion angle alone to estimate foot orientation further emphasize the utility of FFA in assessing toe-walking.

Neurodevelopmental outcome of young pediatric intensive care survivors of serious brain injury.

OBJECTIVES: To determine the number of children with severe brain injury due to closed head injury or hypoxic-ischemic encephalopathy as a proportion of all admissions of children <3 yrs of age in the regional pediatric intensive care unit; to determine the outcome of these children at >6 mos postinjury; and to explore the relationship of outcome measures to predictors of outcome obtained within the first 24 hrs after brain injury. DESIGN: Prospective, descriptive outcome study of an inception cohort. RESULTS: Neonatal and Infant Follow-up Clinic, Glenrose Rehabilitation Hospital, Edmonton, Canada. PATIENTS: Of a cohort of 53 children of <3 yrs of age (4% of pediatric intensive care unit admissions, 1995-1998) admitted for severe acquired brain injury (Glasgow Coma Score, 80% have adverse outcome of death, disability, or mental or motor developmental scores below average. A Glasgow Outcome Scale of 5 overestimates good recovery. Universal registry and follow-up of these children are needed.

Childhood morbidity after severe traumatic brain injury: Increased detection with the Multiattribute Health Status Classification.

OBJECTIVES: Study 1: To determine the interrater agreement on the Multiattribute Health Status Classification (MAHSC) for brain-injured children. Study 2: To determine the outcome of severe childhood traumatic brain injury (TBI) by comparing three measures: MAHSC, Functional Independence Measures (FIM/WeeFIM), and the Glasgow Outcome Scale. Designs: Study 1: Clinic recruitment of parents of patients. Study 2: Surveillance follow-up of an inception cohort. Settings: Study 1: The Brain Injury Clinic, Glenrose Rehabilitation Hospital, Edmonton, Canada. Study 2: Pediatric Intensive Care Unit, University of Alberta Hospital. PATIENTS: Study 1: Two physiatrists and parents of 50 children (5-18 yrs, 54% boys) independently completed the survey. Study 2: From a cohort of 51 patients (3-17 yrs, 69% boys, 6 deaths) consecutively admitted to the pediatric intensive care unit in 1995 and 1996 with severe TBI (Glasgow Coma Score
