Protective helmets for children with special health care needs.

An illustrative case of a second traumatic brain injury in the same child raises the issue of the criteria by which protective helmets for disabled children should be prescribed. There is a dearth of data substantiating criteria for helmet prescription for special needs children and assessing potential adverse side effects of routinely wearing a helmet. Further studies seem warranted to determine whether protective helmets truly reduce the frequency and severity of secondary trauma and whether there are adverse effects that outweigh benefits.
