Abstract
Objective: To investigate the association between evoked
potentials and fractional anisotropy (FA) ratio in posterior
limb of the internal capsule and hand movement scale
(HMS) in post-stroke hemiplegic patients.
Method: Thirty-six post-stroke hemiplegic patients with a
lesion in the internal capsule were included in this study.
Diffusion tensor imaging (DTI) was performed with a 3.0
tesla MR at about 1 month after stroke. FA ratio was
measured in posterior limb of the internal capsule of the
patients. Motor evoked potential (MEP) was obtained by
magnetic stimulation of the motor cortex and recorded from
the abductor pollicis muscle. Somatosensory evoked
potential (SSEP) was obtained by electrical stimulation of
the median nerve at the wrist and recorded from the
somatosensory cortex. Hand movement scale was obtained
at about 1 month and 3 months after stroke.
Results: Hand movement scale at about 1 month and 3
months after stroke and FA ratio were reduced significantly
in patients who showed no response on MEP. However, no
significant differences were observed between the patients
who showed SSEP response and those who did not. FA ratio
and hand movement scale were highly correlated to each
other.
Conclusion: MEP and FA ratio can be helpful in assessing
the hand function at about 1 month and 3 months in
post-stroke hemiplegic patients.
