Neurological function changes in rhesus macaques at 1 day prior to and 3, 10 and 60 days following model establishment.

At 1 day prior to model establishment, scores of Clinical Rating Scale for stroke were 0, indicating normal neurological function. At 3 days post-surgery, the scores were 24, indicating peak degree of neurological function injury. Up to 10 days, the scores decreased to 20, demonstrating that the neurological function improved (higher scores indicate more severe injury). At 60 days, the scores further decreased to 6, indicating that neurological function was further improved, but not restored to normal (mean, n = 3, Kruskal-Wallis test). As the scores of Clinical Rating Scale for stroke were not normally distributed, the mean was not expressed as SD or SEM.
