Abstract
|
|
|
Objective: The Present study was undertaken to evaluate prognostic significance of evoked potentials in patients with stroke.
Methods: We reviewed the medical records of the 69 patients with stroke who received rehabilitation services and were evaluted with evoked potential study. The finding of visual evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs), somatosensory evoked potentials (SSEPs) were compared with the patients´ Characteristics, such as demographic factors, past medical history, etiology, clinical symptoms and functional and cognitive functions.
Results: The petients with mellitus, aphasia, sensory impaurment or hemorrhage showed higher abnormal responses in median and tibial SSEPs as compared to patients at admission and discharge. However FIM gain and FIM efficiency were not correlated with the SSEP findings. The findings of BAEPs and VEPs were not correlated with patients´ characteristics.
Conclusion: SSEP would be helpful for eveluating the cognitive and functional state of the patients with stroke. however, they did not accurately predict the functional gains.
