Longitudinal Changes in Factors Associated with Walking Independence at Hospital Discharge in Patients with Stroke: A Retrospective Study.

: Patients with stroke usually have long-term residual gait disability. However, temporal changes in factors associated with gait independence in these patients at the time of hospital discharge have not been clarified. This study aimed to determine changes over time in factors associated with gait independence in patients with stroke at the time of hospital discharge. This would predict that factors associated with the level of walking independence in patients with stroke at discharge from the hospital would show different results depending on the changes over time post-stroke onset. : This retrospective observational study used data from the medical records of patients with stroke with unilateral supratentorial lesions who were admitted and rehabilitated at Tesseikai Neurosurgical Hospital between October 2020 and July 2024. The Functional Ambulation Category (FAC), Stroke Impairment Assessment Set-lower extremity motor items, Trunk Control Test, Mini-Balance Evaluation Systems Test (Mini-BESTest), and Functional Independence Measure cognitive items were assessed monthly for 3 months post-stroke onset. Participants were classified into independent and non-independent walking groups using the FAC. Logistic regression analysis was performed with walking independence at discharge and other assessment indicators as the dependent and independent variables, respectively, to identify factors influencing walking independence at discharge. Independent variables were entered by month from 1 to 3 months. : Logistic regression analysis revealed that Mini-BESTest scores at 2 and 3 months post-stroke onset were significantly associated with walking independence at discharge ( < 0.05). : This study suggests the importance of assessing the Mini-BESTest scores over time, starting at 2 months post-stroke onset, when determining walking independence in patients with stroke. Providing balance training to patients with low Mini-BESTest scores between 1 and 3 months post-stroke onset may contribute to improved walking independence at discharge.
