Abstract

Pediatric traumatic brain injury often leads to long-term disability. Unfortunately, while currently used standard clinical measures can effectively capture secondary functional impairments, they do not measure neurologic impairment directly.

Introduction

Traumatic brain injury (TBI) in children is a significant public health burden in the United States and can lead to severe disability. It has been estimated that more than 60% of children with moderate to severe TBI experience long-term disability [1], with the majority having complete or near-complete loss of walking ability in the acute period [2].

Materials and methods

This was an exploratory study with a convenience sample of children and adolescents (ages 4–18) admitted to an inpatient rehabilitation unit after sustaining a severe TBI. All study procedures were approved by the University of Minnesota Institutional Review Board (#00006147).

Results

Four participants with severe TBI were enrolled in this pilot study (Table 2). The principal investigator, study therapist, and study staff determined the more impaired side according to clinical measures of strength and motor control.

Discussion

This pilot study indicates that using only standard clinical assessments to monitor recovery from TBI may mask ongoing functional deficits, leading to a significant discrepancy between perceived and measured outcomes. These clinical measures are lagging indicators of recovery and do not capture the compensatory strategies a person may use to overcome continued neurologic impairment.

Conclusion

Pediatric TBI remains a significant public health burden in the United States and can lead to severe disability. Identifying a quantitative metric to measure impairment severity, track functional recovery, and potentially serve as a leading indicator to guide intervention is a key goal for improving treatment and enhancing recovery post-TBI.
