The aim of this study is to compare the role of magnetic motor evoked potentials(MEPs) with somatosensory evoked potentials(SEPs) in predicting functional recovery of hemiparesis in stroke patients. Twenty-five stroke patients were evaluated clinically and electrophysiologically at about one month after stroke. Outcome parameter was the modified Barthel index, gait state at discharge. MEP was better than SEP at predicting an outcome in terms of functional recovery. MEP has high positive specificity and SEP has high negative specificity in terms of gait state. So MEP in conjunction with SEP may offer a means of more accurately predicting functional outcome following stroke than can be achieved with SEP. There was a significant relationship between MEP and motor function.

Key Words: Motor evoked potential, Somatosensory evoked potential, Stroke, Outcome
