Other evidence does show post-traumatic amnesia to be valid, and it probably remains the best simple prognostic item available. The misclassification rate however, is significant enough that some caution should be taken in individual cases. CONCLUSIONS: The assessment of post-traumatic amnesia with the Rivermead post-traumatic amnesia protocol is reasonably reliable. In all groups 19%-25% of patients changed categories between assessments, but only 2% changed by two categories. RESULTS: Overall correlation was good (Spearman's r 0.79), but the correlation was lower for patients with post-traumatic amnesia < 24 hours and when there was a long delay between assessments. Severity was categorised with standard criteria. The Rivermead post-traumatic amnesia protocol involved clinical questioning of the patient to establish how long after injury (in hours/days/weeks) the patient regained continuous day to day memory. These were group A: 12 inpatients with very severe head injury late after injury Group B: 40 patients interviewed at home six months after injury group C: 22 patients interviewed within a few weeks of injury at home group D: 116 patients interviewed initially within a few weeks and then at six months, on both occasions at home. Four different patient groups were studied. Assessments were undertaken both in hospital and in the patients' homes. Analysis investigated the correlations between assessments, the percentage difference between assessments, the number of patients changing category, and the differences between these analyses in the different patient subgroups. DESIGN: Two independent assessments using the Rivermead post-traumatic amnesia protocol were undertaken by separate observers on various groups of patients at various time intervals. To establish its limits and factors which influence reliability. Occupational therapy intervention based upon the PRPP System of Task Analysis and Intervention improved subjects' ability to apply information processing strategies during occupational performance when compared to current intervention approaches.OBJECTIVE: To develop and test a clinical protocol for determining post-traumatic amnesia by retrospective questioning. Subjects demonstrated improved information processing strategy use both prior to and following emergence from PTA. Large treatment effects favoured the PRPP Intervention. Seven subjects significantly improved in their application of processing strategies during the PRPP Intervention in comparison to current OT Intervention phases. PRPP Intervention adopts an information processing approach that simultaneously focuses on task training, strategy training and strategy application within occupational performance. ![]() The PRPP System is a dynamic assessment and intervention approach that directly links results of cognitive task analysis with strategies for intervention. PTA status was monitored with the Westmead PTA Scale. Information processing capacity during occupational tasks was measured using the PRPP System of Task Analysis. Current OT intervention was alternated with the experimental Perceive, Recall, Plan and Perform (PRPP) System approach over 4-weeks. Single-system experimental design (ABAB) across subjects.Įight subjects were recruited during acute rehabilitation. To investigate the effectiveness of occupational therapy (OT) with adults demonstrating agitation and post-traumatic amnesia (PTA) following brain injury. ![]()
