OBJECTIVE: To delineate whether functional recovery after stroke, determined by
the modified Rankin Scale during the neurologically stable chronic stage, is
associated with the presence or absence of motor evoked potential or
somatosensory evoked potential measured during the sub-acute stage at the
commencement of rehabilitation. DESIGN: Retrospective medical records review.
PATIENTS: Consecutive 105 first-ever unilateral patients after stroke. METHODS:
Patients underwent motor evoked potential and somatosensory evoked potential
studies at the commencement of rehabilitation (i.e. approximately 1 month
post-onset), and functional recovery was measured using the modified Rankin Scale
at 3 months post-onset. The independent abilities of motor evoked potentials and
somatosensory evoked potentials for predicting good functional recovery (modified
Rankin Scale < or = 2) were determined by multivariable logistic regression
analysis adjusted for age, laterality of lesion, and National Institute of Health
Stroke Scale scores at onset of rehabilitation. RESULTS: The adjusted logistic
regression model revealed that patients with negative motor evoked potential or
somatosensory evoked potential responses in the lower limb were less likely to
achieve good functional recovery (odds ratio=0.057-0.099, p<0.05) relative to
positive motor evoked potential and somatosensory evoked potential responses in
the lower limb. CONCLUSION: Evoked potential studies measured at the commencement
of rehabilitation could be used in a complementary manner to predict functional
recovery after stroke.
