Postural Maintenance Is Associated With Walking Ability in People Receiving Acute Rehabilitation After a Stroke.

Abstract

The Postural Assessment Scale for Stroke Patients (PASS) assesses the ability of people post stroke to maintain or change a given posture from lying to standing, and the items on which people with different walking status perform differently may suggest potential interventions. The purpose of this study was to (1) examine the association of PASS scores at admission for acute rehabilitation with walking status at admission and 3months post stroke (3 M), and (2) identify PASS items that discriminate walking status. In this prospective observational study, 93 people post stroke were assessed with the PASS and a 2.44-m gait speed test at admission, with walking status assessed by telephone interview at 3 M. Those who could walk over a 2.44-m distance without the assistance of a walking aid or another person were considered to be independent in walking; others were considered to be dependent. Those who were dependent at admission were divided into the "regained independence" and "remained dependent" groups based on their status at 3 M. The association of the PASS at admission with 3 levels of walking status (independent at admission, regained independence, and remained dependent) was examined using the Kruskal-Wallis test. For those dependent at admission, the association of PASS score at admission with walking status at 3 M was examined using logistic regression and receiver operating curve analysis. PASS scores at admission differed significantly across the 3 walking status groups and were significantly associated with walking status at 3 M (odds ratio = 0.864; 95% CI = 0.798-0.935) over and above length of stay. People post stroke who were dependent at admission and had PASS scores ≥22 were more likely to regain independence at 3 M. Nine PASS items differed among the 3 groups. PASS score is significantly associated with walking status at admission and at 3 M. The identified 9 items suggest possible interventions for acute rehabilitation. This study identified 9 PASS items that could guide clinicians in selecting interventions for acute rehabilitation.
