Description
Summary:To investigate predictors indicating the continuous need for a knee-ankle-foot orthosis (KAFO) at 1 month after stroke onset in patients who cannot walk without a KAFO in the acute period. We enrolled patients with severe hemiplegia (n=139) who were unable to walk without a KAFO on day 10 from stroke onset. The patients were divided into two groups depending on the need for a KAFO at 1 month after the onset: the KAFO group and non-KAFO group. Logistic regression analysis was used to identify predictors of the continuous need for a KAFO at 1 month after stroke onset. In addition, significant predictors were analyzed using receiver operating characteristic curves. The number of patients in the KAFO group and non-KAFO group was 72 (51.8%) and 67 (48.2%), respectively. Motor deficit, sensation disorder, severity of pusher syndrome, and body mass index were identified as predictors of the continuous need for a KAFO. Moreover, active range of motion of knee extension on the affected side was found to have the highest predictive ability, with an area under the receiver operating characteristic curve of 0.89 (95% confidence interval, 0.83–0.94). In this study, multiple factors were associated with the continuous need for a KAFO at 1 month after stroke onset. In particular, active range of motion of knee extension on the affected side is suggested to be a highly accurate predictor for the need for a KAFO in the subacute phase.
