The Rey figure copy as a screening instrument for perceptual defictits after stroke

Abstract

The aim of the study was to investigate the use of the Rey figure for screening patients for perceptual impairment following stroke. Stroke patients in a trial of a stroke unit were assessed using the Rey figure copy at entry to the study. Those admitted to the stroke unit were also assessed on the Rivermead Perceptual Assessment Battery (RPAB). In 61 patients assessed consecutively on both tests, using conventional clinical cut-off points the Rey figure copy was impaired in 31 out of 32 patients who were impaired on the RPAB. Fifteen patients who failed the Rey figure did not have perceptual problems on the RPAB, indicating that deficits on the Rey figure are not only due to perceptual problems. A receiver operating characteristic curve was plotted to compare different cut-off points. The Rey figure may be used as a brief screening assessment for perceptual deficits following stroke
