Abstract
<p>Background: Some patients with TBI (traumatic brain injury) might go on to manifest attentional deficit in the workplace although they performed well in standard neuropsychological tests. We, therefore, developed an original paper-and-pencil type dual-task (Oiso DT-A) for assessing inattention. We showed that the Oiso DT-A might be valuable and sensitive for detecting inattention including mild deficit. The task, however, was not applicable for patients with the dominant-hand dysmobility because it included written calculation. The purpose of this study was to investigate the validity of newly developed DT (Oiso DT-B) which could be completed with the non-dominant hand.</p><p>Methods: A total of 134 healthy individuals and 36 TBI patients were the subjects. The Oiso DT-B combined visually and audibly presented selective cancellation-tasks. A subject was required to identify and respond to both target stimuli of number 7 (visual sub-task) and words with three letters (auditory sub-task) for three minutes. The performance was scored based on the correct rate (both sub-tasks), success rate (both sub-tasks), and the number of correct answers in the visual sub-task. Performances of Clinical Assessment for Attention (CAT) developed by The Japan Society for Higher Brain Dysfunction and Kana pick-up test were also measured for TBI patients.</p><p>Results: All patients could complete Oiso DT-B without a difficulty. Based on a simple and unique definition of cut-off values, abnormal performance in TBI patients was detected more frequently in the Oiso DT-B than in any sub-task of CAT and Kana pick-up test although the specificity values were comparable.</p><p>Conclusion: The Oiso DT-B as well as DT-A also might be valuable and sensitive for detecting inattention including mild deficit.</p>
