Abstract
Objectives: To investigate the relationship between language functions and cognitive and functional outcome and to evaluate the effects of a conventional language rehabilitation programme on aphasic adult patients in the post-acute stage of traumatic brain injury (TBI).
Design: Non-concurrent prospective study. Patients were assessed pre-treatment and post-treatment with standardized assessment tools.
Subjects: Sixty-one aphasic patients with TBI who were admitted to a rehabilitation centre in the post-acute phase for a late inpatient rehabilitation programme.
Methods: The motor sub-scales of the Functional Independence Measures and Disability Rating Scale were used to assess functional status and disability. Cognitive status was evaluated with the Mini-Mental Status Examination and the Functional Independence Measure cognitive sub-scale. The language function was evaluated with the Gülhane Aphasia Test.
Results: All functional, cognitive and language scores increased significantly during the rehabilitation programme. Language functions at admission were correlated with the Functional Independence Measure motor change scores and the Mini-Mental Status Examination change scores. Regression analyses revealed that auditory comprehension at admission was the most important independent determinant of functional and cognitive gain during rehabilitation.
Conclusion: Post-acute language functions after late admission to a rehabilitation centre appear to be related to measures of cognitive and functional progress in patients with TBI. Functional and cognitive outcome is mainly affected by auditory comprehension. Results also showed the effectiveness of post-acute conventional rehabilitation in improving language functions.
