Abstract

The central somatosensory conduction time(CCT) was measured by recording the cerebral and spinal evoked potentials following median nerve stimulation in 24 traumatic brain injury patients. The findings of evoked potential study correlated to the functional independence measure(FIM), mini mental status examination(MMSE) and Glasgow outcome scale(GOS). The CCT of head injured patients was prolonged compared to that of the controls. The CCT with stimulation of the affected side was significantly prolonged compared to that with non- affected side. Abnormal CCT was related to the poor functional status measured by FIM and GOS. There`s no significant difference between groups of absent evoked potential and prolonged CCT by FIM score. These results suggest that the CCT correlates with the functional status of head injured patients. Follow up studies are required to evaluate whether the CCT could be a valuable prognostic indicator or not.
