| Outline of Final Research Achievements |
The relationships between fractional anisotropy (FA) of MRI diffusion-tensor imaging (DTI) and long-term outcome were assessed in patients after stroke. DTI data were obtained on days 14-18 and FA within the corticospinal tracts were calculated. Motor outcome of hemiparesis was evaluated using Brunnstrom stage (BRS) for separate shoulder/arm, hand, and lower extremity functions when patients were discharged from a long-term rehabilitation facility (2-7 months after onset). FIM-motor data were also scored. The ratio of FA in the affected hemisphere to those in the unaffected hemisphere (rFA) was assessed in relation to BRS and FIM-motor data. Analysis revealed tight relationships between rFA and upper extremity function (R, 0.63-0.78) and moderate relationships between rFA and lower extremity function (R, 0.59-0.63). The relationships between rFA and FIM-motor were less evident (R, 0.28-0.44). DTI-FA values may be useful for the prediction of long-term outcomes of stroke patients.
