The aim of this study was to reveal predictors of gait independence at 15 days after stroke onset using a functional assessment of patients and decision tree analysis at stroke onset. [Participants and Methods] A total of 612 acute stroke patients were enrolled in this study. A total of 26 independent variables were measured at stroke onset: age, gender, disease name, the Stroke Impairment Assessment Set (SIAS), Short Form Berg Balance Scale (SFBBS) total score, Timed Up and Go Test-Reserve (TUG-R), cognitive Functional Independence Measure (FIM) total score and 10-meter walk test. The dependent variable was walking ability. Based on the data, a decision tree for predicting independence of gait 15 days after the onset of stroke was developed. [Results] The SFBBS, a balance assessment, was at the top of the scale, suggesting that it was a strong predictor of gait independence. The results also showed that each of the factors with low values had interrelationships with other factors as if to compensate for them. [Conclusion] These results suggest the importance of assessing balance and gait function in predicting gait in acute stroke.
Objective: To synthesize available evidence from case reports regarding the efficacy of knee–ankle–foot orthosis (KAFO) on functional mobility and activities of daily living (ADL) in patients with stroke.Methods: The following databases were searched, based on the Population Intervention Comparison Outcome (PICO) model: PubMed, CINAHL, Scopus, Cochrane Central Register of Controlled Trials, PEDro, Web of Science, and Igaku Chuo Zassi (in Japanese). Methodological quality was assessed using the CARE checklist.Results: A total of 14 articles, including 15 cases, were selected. Clinically meaningful improvement in functional mobility was reported in 10 of 15 cases, measured using the Functional Ambulatory Category, Trunk Control Test, walking speed, and Berg Balance Scale. Clinically meaningful improvement in ADL was reported in 9 of 15 cases, measured using the Barthel Index and Functional Independent Measure. However, the methodological quality of the reviewed articles was low, with missing information on limitations of management, adverse events, and patient-reported outcomes.Conclusion: This systematic review of case reports found limited evidence of the efficacy of KAFO in terms of improvement in functional mobility and ADL. Of value, this study revealed the optimal outcomes for measuring the efficacy of KAFO.
This study aimed to identify predictors of gait independence in three successive patient cohorts that received inpatient rehabilitation for at least 30 days, 60 days, or 90 days post-stroke. A total of 26 independent variables were collected within 3 days of stroke onset, including basic information (age, sex, stroke type), sensorimotor function (Stroke Impairment Assessment Set), gait function, balance function, and cognitive function. The dependent variable was walking independence (without assistance from another person) at 30, 60, or 90 days post-stroke. A decision tree was developed for predicting gait independence at each assessment time point. The predictors of walking independence differed among the cohorts that received inpatient rehabilitation for at least 30, 60, and 90 days post-stroke. Specifically, the Short Form Berg Balance Scale score was in the higher layer and was a strong predictor of gait at all time points. The cognitive Functional Independence Measure progressed to the higher layer at later time points. The lower extremity motor function was an additional predictor in the 30-day cohort. For later cohorts, the predictive value of balance and cognitive function declined whereas the contribution of the paralyzed grip strength and trunk function increased. These results suggest that sensorimotor and cognitive function within 3 days of stroke can predict walking independence between 1 and 3 months post-stroke; however, the prognostic value of predictors varies among the patients who receive inpatient rehabilitation for shorter versus longer time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
