Objectives:
This study examines the prognostic validity of the Scale for the Assessment and Rating of Ataxia for patients with acute stroke.
Materials And Methods:
We enrolled 120 patients with posterior circulation stroke having ischemic or hemorrhagic lesions with ataxia who had physical therapy. We recorded the clinical stroke features and obtained the scale for the assessment and rating of ataxia and National Institutes of Health Stroke Scale scores 7 days after admission and at discharge. Predictive factors for a 3-month modified Rankin Scale score of <3 were investigated.
Results:
During hospitalization, the Scale for the Assessment and Rating of Ataxia score decreased from 7.5 (interquartile range, 4.5-12.5) to 4.0 (interquartile range, 1.5-8.0) points, whereas the National Institutes of Health Stroke Scale score changed from 1 (interquartile range, 0-3) to 1 (interquartile range, 0-2) point. A significant correlation between functional outcome and the Scale for the Assessment and Rating of Ataxia scores 7 days after onset was observed. The cutoff value for the assessment and rating of ataxia for predicting favorable outcome (modified Rankin scale, 0-2) at 3 months post-onset was 14 points (0-40) at 7 days after onset.
Conclusions:
The Scale for the Assessment and Rating of Ataxia scores showed good responsiveness to neurological changes in patients with acute ataxic stroke, could predict functional outcomes 3 months after onset on day 7, and could be a useful and reliable marker for patients with ataxic stroke.
