Rehabilitation of children with traumatic brain injury: a critical review.

The purpose of this critical review of the English literature published between 1975 and 2009 was to assess the quality of the evidence for the efficacy of rehabilitation intervention after traumatic brain injury in children. "Evidence for intervention studies" was used to classify the research strength of design and report. Only a minority (16/439) of the published studies has been related to traumatic brain injury in children and has used a scientific or quasiscientific design. Only one study met the criteria of class I "evidence for intervention" studies. However, this study included adults, as well as children. The other 15 studies, although reporting positive results, had many methodologic deficiencies, and consequently their validity is questionable. Although the methodologic and ethical difficulties involved are acknowleged, a multicenter approach is required to achieve valid conclusions. Use of designs such as comparative effectiveness research might prove to be a practical solution. High-quality intervention research would facilitate stronger evidence-based counseling for children and families requiring posttraumatic brain injury intervention and to policy makers.
