Abstract
The aim of this work was to study (he role of motor evoked potentials
(MliPs) latency and amplitude obtained by transcranial magnetic stimulation
(TMS) in predicting the prognosis of acute ischcmic stroke.
The study was carried out. on 20 patients with acute ischcmic stroke (mean
age 53.95 i 7.19 year). All the studied patients had hemiplegia or hcmipnrcsis.
Patients were selected having no evidence of cerebral hemorrhage, peripheral
neuropathy, median nerve entrapment, epilepsy or head injury.
The studied patients were subjected to history taken, neurological
examination and functional evaluation for the paretic upper and lower limbs.
The first functional evaluation was performed prior to the neurophysiologieal recording, and it was done according to the method described by Chino. During the second week after stroke onset (mean duration 8.4 4 2.01 day), TMS was performed with MEP recording from the four extremities (paralyzed and non-paralyzed sides) for each patient. All studied patients received traditional rehabilitation program (exercise therapy and gait training) for three months duration. At the end of the third month, a second functional evaluation was done using the same previous used technique (i.e. Chino method).
