Raw, demographically altered, and composite Halstead-Reitan Battery data in the evaluation of adult victims of nonimpact acceleration forces in motor vehicle accidents.

Data from the Halstead-Reitan Neuropsychological Test Battery were interpreted for 33 adults who had been subjected to nonimpact acceleration forces in motor vehicle accidents. Comparisons with normative data provided by Reitan and Wolfson (1993) identified impaired performance on the Localization component of the Tactual Performance Test and the Category Test and atypical right-left differences on the Tactual Performance Test and Grip Strength. In contrast, comparisons with a normative data set developed by Heaton, Grant, Matthews, and PAR Staff (1991) through T-score conversions produced results that suggested normal cognitive skills. The Neuropsychological Deficit Scale score was one of the clearest indicators of neuropsychological impairment, falling generally well within the mildly impaired range.
