The purpose of this study is to describe the relationship between median nerve somatosensory evoked potential (SEP) parameters and clinical measures of motor impairment and physical disability in the affected upper limb of patients with hemiparesis. SEP assessments were carried out in 28 long-term survivors of stroke. Stroke survivors with preserved SEPs over the affected hemisphere exhibited significantly lower motor impairment and physical disability than those with absent waveforms. Among those with preserved waveforms, SEP amplitude exhibited a weak correlation with degree of upper limb motor impairment. The correlation between SEP amplitude and physical disability was not statistically significant. Contrary to prior reports, median nerve SEP appears to have a weak correlational relationship with clinical measures of upper limb function in hemiparesis.
