RECOVERY OF AUTOMATIC AND COGNITIVE FUNCTIONS IN TRAUMATIC BRAIN INJURY USING THE FUNCTIONAL INDEPENDENCE MEASURE

Automatic tasks are performed with minima attentional guidance. Neural pathways subserving attention are often impaired in traumatic brain i njury (TBI). Therefore, the process of automatization is crucial in sk ill development, due to the fact that it allows attention to be direct ed towards the more abstruse components of task [1]. Automatic and cog nitive categories were created by aggregating three of the motor items and three of the cognitive items respectively of the Functional Indep endence Measure (FIM). The averages of these categories were calculate d for every evaluation of the FIM, and their relationshp to each other was examined. Over a 9-month period 24 patients were selected from a TBI population with a major component of diffuse axonal injury (DAI). Eight-eight per cent (n = 21) of the patients reached independence for the automatic category, but only 29% (v = 7) reached this level for t he cognitive category. When independence was achieved, the average tim e to do so for the automatic category 6.7 weeks) was not significantly different from the time it took to reach cognitive independence (6.9 weeks). It was found that there were significant statistical differenc es in the scores between the two categories. Premorbid IQ had no effec t on these categories. However, the rate which these two categories in creased, from the time of admission to discharge, was not significantl y different.
