The correlation of the short latency somatosensory evoked potentials and the strokes disability

Median and tibial short latency somatosensory evoked potentials (SSEPs) were studied in 54 stroke patients, 27 males and 27 females. Thirty-two patients had cerebral infarction and 22 had cerebral hemorrhage. Median SSEPs abnormalities correlated with the Barthel score (p = 0.005) as well as tibial SSEPs (p = 0.01). Both median and tibial SSEPs were very sensitive (sensitivity = 79.41% and 85.71%) and high positive predictive value (77.14% and 75%) in the assessment of neurological disability. However, normal median and tibial SSEPs did not exclude severe neurological deficits (positive predictive value = 63.16%, 64.29% and sensitivity = 60%, 47.37%).
