Hemispatial Neglect: Computer-Based Testing Allows More Sensitive Quantification of Attentional Disorders and Recovery and Might Lead to Better Evaluation of Rehabilitation

Abstract

which are particularly evident when the tests are repeatedly administered during recovery (see First, PnP tests typically do not change from one examination to the next, allowing for significant learning and compensatory strategies. Second, they are static, further allowing the implementation of compensatory strategies while not reflecting the dynamic character of the natural environment. These characteristics, coupled with the fact that only accuracy is measured, lead to early "normalization" of PnP scores, or a ceiling effect, when the patient may still demonstrate significant behavioral abnormalities in everyday life situations. Furthermore, in cancellation tests, a common type of PnP test, the tests are typically summarized into a single score, with no indication of performance variance which may be in itself a sensitive marker of the deficit
