Abstract

LUVIZUTTO, Gustavo José et al. Aspects correlates with Scandinavian Stroke Scale for predicting early neurological impairment. Arq. Neuro-Psiquiatr. [online]. 2015, vol.73, n.5, pp.450-453.  Epub Apr 17, 2015. ISSN 0004-282X.  https://doi.org/10.1590/0004-282X20150037.

Objective

To investigate the correlation between the Alberta Program Early CT Score (ASPECTS) and the Scandinavian Stroke Scale (SSS) for the evaluation of neurological impairment in patients with acute stroke.

Method

59 patients with a first acute ischemic stroke were evaluated. The ASPECTS were evaluated by 2 neurologists at admission and by another neurologist after 48 hours. The NIHSS and SSS was applied to determinate stroke severity. Correlations and agreements were analysed statistically by Spearman and Kappa tests.

Results

ASPECTS was correlated with National Institute of Health Stroke Scale (NIHSS) at admission (r = -0.52; p < 0.001) and SSS (r = 0.50; p < 0.001). The ASPECTS and SSS items were most correlated with arm (r = 0.52; p < 0.001) and hand (r = 0.49; p < 0.001) motor power, and speech (r = 0.51; p < 0.001). The SSS of 25.5 shows sensitivity (68%) and specificity (72%) when associated with ASPECTS ≤ 7.

Conclusion

The SSS can predict worst neurological impairment when associated with lower values of ASPECTS.
