Cognitive dysfunction in spinal cord injury patients: sensitivity of the Functional Independence Measure subscales vs neuropsychologic assessment.
The Functional Independence Measure (FIM) has been developed to provide an objective measure of functional gains during acute and chronic rehabilitation of disabled individuals, including those with spinal cord injury (SCI). A unique characteristic of the FIM, as compared with other functional scales, is that it reflects abilities in the areas of communication and social cognition. In order to examine the external validity of these subscales, 41 acute SCI patients were evaluated with the FIM just before discharge from acute rehabilitation. The subscale scores were compared to the results of a comprehensive, predominantly motor-free, neuropsychologic battery administered 74.8 +/- 5.3 days postinjury. Evaluation of scatter plots indicated that there were no relationships between any neuropsychologic test results and the discharge FIM social cognition or communication subscale scores. This was attributed to a ceiling effect in the FIM ratings. The results of this study suggest that the FIM cannot be a substitute for comprehensive neuropsychologic assessment in SCI patients.
