An early and intensive rehabilitation program in a Japanese hospital affects functional outcomes of acute stroke patients. Implications for Rehabilitation Early and intensive rehabilitation for the stroke patients is an effective means of improving FIM score. Early and intensive rehabilitation affects the improvement of FIM efficiency without increasing adverse events.
[Purpose] The efficacy of diffusion tensor imaging in the prediction of motor outcomes
and activities of daily living function remains unclear. We evaluated the most appropriate
diffusion tensor parameters and methodology to determine whether the region of interest-
or tractography-based method was more useful for predicting motor outcomes and activities
of daily living function in stroke patients. [Subjects and Methods] Diffusion tensor
imaging data within 10 days after stroke onset were collected and analyzed for 25
patients. The corticospinal tract was analyzed. Fractional anisotropy, number of fibers,
and apparent diffusion coefficient were used as diffusion tensor parameters. Motor
outcomes and activities of daily living function were evaluated on the same day as
diffusion tensor imaging and at 1 month post-onset. [Results] The fractional anisotropy
value of the affected corticospinal tract significantly correlated with the motor outcome
and activities of daily living function within 10 days post-onset and at 1 month
post-onset. Tthere were no significant correlations between other diffusion tensor
parameters and motor outcomes or activities of daily living function. [Conclusion] The
fractional anisotropy value of the affected corticospinal tract obtained using the
tractography-based method was useful for predicting motor outcomes and activities of daily
living function in stroke patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
