Predictors of Functional and Gait Outcomes for Persons Poststroke Undergoing Home-based Rehabilitation

Abstract

The literature on the impact of home-based rehabilitation on functional outcomes for patients after stroke is limited. The purpose of this study was to describe the outcomes of home-based rehabilitation (HBR) on functional and gait performance for patients after stroke and associated factors that contribute to better outcomes after an episode of care. The nature of the study design was retrospective and the settings used were home care services. The total number of subjects receiving home care services after stroke was 213 (mean age 76.5±9years, 51% female). Treatment records for patients receiving HBR in 2010 were reviewed at the start of care and discharge. The primary outcome measure was a change in a gait speed and activities of daily living (ADL) performance between admission and discharge from home health care services. The composite score to calculate overall functional status (Outcome Information and Assessment Set-version C [OASIS-C]) was used. Mean change in ADL and gait scores and factors predictive of improvement were identified using an analysis of covariance and multivariate linear models. The main outcome measures were change in the OASIS-C composite scores and gait speed. After adjustment for age and ADL score at the start of care, discharge from skilled nursing or long-term facilities, presence of confusion most of the times, cognitive impairment, and memory deficits were negatively associated with an improvement in functional scores (ADL). Living in congregate facilities was also negatively associated with an improvement in gait speed. The best multivariate model included age, baseline ADL composite scores, confusion status, and gait speed at the start of care, which predicted 41% of the variance in ADL score changes over the course of intervention. Gait speed and ADL scores at the start of care had largest influence on functional and gait improvement. Type of discharge facility, confusion status, and living arrangement had effects on HBR outcomes for stroke survivors.
