Abstract

Introduction:

Differences between perceived ability and functional capability in stroke survivors may cause differences in an individual’s performance of a motor task compared to their capability to perform that task. This study aimed to determine if perceived strength and mobility are associated with observed gait function in stroke survivors.

Methods:

Clinical outcome measures were collected, including the Stroke Impact Scale (SIS), Six-Minute Walk Test (6MWT), and Timed Up and Go Test (TUG). Individuals were divided into groupings based on whether they were considered safe or at-risk during community ambulation according to their 6MWT (safe > 0.8 m/s) and TUG (safe < 12 seconds) results.

Results:

There were moderate positive correlations between 6MWT and SIS mobility and negligible correlations between 6MWT and SIS strength for both the safe and at-risk groups, with no significant differences between risk groups. TUG performance and perceived mobility had a moderate negative correlation for the safe group and a weak negative correlation for the at-risk group, but the differences between risk groups were not significant. There was no significant difference between TUG vs SIS strength relationships between risk groups.

Discussion:

The results of this study call attention to a gap between perceived performance and ambulation risk assessment. The lack of a strong relationship between SIS subdomains and 6MWT/TUG results indicates that SIS strength and mobility subdomains cannot be used to differentiate between those considered at-risk and safe during ambulation as determined by the 6MWT and TUG test performance thresholds.

I will bring a thumb-drive with presentation slides so somewhere to plug that in and a screen to display slides
