Inpatient rehabilitation of working-age adults with ischemic stroke: comparing men and women clinical and functional characteristics at admission and predicting functionality.

introductionThe role of gender in functional independence for activities of daily living after ischemic stroke is still controversial. We aim to a) compare clinical characteristics of men and women at inpatient rehabilitation admission b) compare their functional independence at admission and discharge c) identify predictors of functional independence. MATERIALS AND

methodsRetrospective observational cohort study. State-of-the-art variables were used for admission and discharge comparisons and to predict total FIM (Functional Independence Measure) at discharge, FIM gain, FIM efficiency and FIM effectiveness using multivariate linear regressions.

results144 patients (33% women) admitted to inpatient rehabilitation in a Spanish specialized center, with less than 3 weeks since ischemic stroke onset were included. Men were older (p = 0.039), 19.6% of men had diabetes mellitus (6.4% of women) (p = 0.038), with 52.6% of men being non-smokers (72.3% of women) (p = 0.022). No significant differences were observed in FIM at admission, discharge, FIM gain, efficiency or effectiveness (total, motor either cognitive FIM). Regression analysis identified sex (ß = -0.13), stroke severity (ß = -0.25) and admission total FIM (ß = -0.69) as significant predictors of total FIM gain (R2 = 0.42). The same variables predicted discharge total FIM: sex (ß = -0.12), severity (ß = -0.23) and admission total FIM (ß = 0.59) (R2 = 0.51). FIM efficiency was predicted by admission total FIM (ß = -0.64), severity (ß = -0.24), age (ß = -0.17) and length of stay (ß = -0.45) (R2 = 39.9%). FIM effectiveness model explained only 13.5% of the variance.

conclusionsNo functional differences between men and women in any independence measure were found. Sex was a significant predictor but leaving half of the variance unexplained.
