Correlation Between Motor Impairment and Infarct Volume After Permanent and Transient Middle Cerebral Artery Occlusion in the Rat
Abstract
Background and Purpose There have been a number of recent reports describing the relationship between ischemic damage and various behavioral and functional measures, although there have been few studies that have demonstrated a direct correlation between functional impairment and lesion volume. The purpose of the present study was to assess functional outcome by measurement of motor impairment and to determine whether this correlated to a range of infarct volumes induced by varying the duration of focal ischemic insult in the rat. Methods Male Sprague-Dawley rats were subjected to 0, 30, 60, or 120 minutes or permanent middle cerebral artery (MCA) occlusion by the intraluminal filament technique. Motor impairment was assessed by the accelerating rota-rod and grid-walking tests, and the brains were perfusion-fixed for histological determination of infarct volume and brain swelling 24 hours after MCA occlusion. Results Marked impairment in performance of both motor tests was recorded in the 60-minute, 120-minute, and the permanent MCA occlusion groups when compared with sham-operated rats. There were significant correlations between regional infarct volume, brain swelling, and all behavioral measurements (all r 2 >.5, P <.001). Conclusions The rota-rod and grid-walking tests of motor performance provide quantitative, objective, and reproducible measures of functional impairment of rats following an ischemic insult. These impairments correlate directly with infarct volume and provide information integral to future studies evaluating the effects of potential neuroprotective agents.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
