Background. Clinical assessment of apraxia has followed the different theoretical frameworks that research in this field has proposed over the last decades. Consequently, clinical tests that are in use are not equally sensitive to the apraxic deficit. Moreover, each of them aims to show only certain aspects of the deficit. In the present preliminary study we wish to present the application of a new clinical tool for assessing apraxia, the SISSA Utilization Apraxia Battery (SUAB). Methods. A pilot study was set to assess SUAB's sensitivity to apraxic deficit. Patients were studied in the usual clinical setting, namely the Neuropsychological Office of our Rehabilitation Unit. Three unselected left-hemisphere damaged patients were enrolled in the study. The SUAB is based on a pantomime task of single object use and on the real use of the same objects. The pantomime task follows three different presentations of the objects: visual, auditory and tactile. Patients' scores in pantomiming and in real use were evaluated. Results. Results showed the SUAB to be very suitable for detecting the apraxic deficit. Moreover, it was able to show dissociation within the same patient in pantomiming following different sensorial presentations of the stimuli. Conclusions. Therefore, the SUAB appears to be a sensitive tool for assessing utilization apraxia.
