摘      要：The majority of motor recovery following stroke occurs within 6 months after *** present study examined a patient with a corona radiata infarct,who exhibited an unusual long-term recovery（24 months after onset）.The patient was a 64-year-old female,who presented with severe paralysis of the left extremities resulting from a corona radiate *** recovery from the weakness progressed slowly over a 24-month period following onset,even at 6-12 months after *** tensor tractography at 2 weeks from onset showed disruption of the corticospinal tract of the affected hemisphere resulting from the ***,at 12 and 24 months after onset,the corticospinal tract was elongated to the cortex level,as shown by diffusion tensor tractography.A 2-week transcranial magnetic stimulation showed no motor-evoked potential for the affected hemisphere,but a motor-evoked potential of the corticospinal tract was observed at12 and 24 *** results suggest that motor function recovery in cerebral infarct patients can occur at least up to 24 months after stroke onset.
