Background: This study was to examine the response rate, concurrent validity, and predictive validity of the 10meter Walk Test(10mWT) walking speed and the 6Minute Walk Test(6MWT) total walking distance in sub acute stroke patients Design: Observational study or cross-sectional study Methods: This study utilized data collected from 53 sub acute stroke patients. The evaluations included the 10mWT, 6MWT, Berg Balance Scale(BBS), Timed Up & Go test(TUG), and 5-times Sit to Stand test (5-times STS). The study investigated the Standard Response Mean(SRM) and the concurrent validity of the 10mWT and 6MWT before and after 4 weeks of treatment. Additionally, it examined the predictive validity of the 10mWT walking speed for estimating the total walking distance of the 6MWT before and after 4 weeks of treatment.
Results: The SRM of the 10mWT was found to be high at 1.33, while the total distance covered in the 6MWT also showed a high SRM of 1.28. There was a very strong correlation between the 10mWT and 6MWT be fore treatment(r=.937, p<.01). The concurrent validity of the 10mWT showed significant relationships with the TUG (r=-.805), 5Times STS(r=-.651), and BBS(r=.719)(p<.05∼.01). Similarly, the concurrent validity of the 6MWT was significantly correlated with TUG(r=-.760), 5Times STS(r=-.643), and BBS(r=.717) before treatment. Variables such as age, sex, duration of illness, cognition, TUG, 5Times STS, and BBS were excluded from predicting 6MWT outcomes, leaving only 10mWT, which explained 87% of the variance in 6MWT performance.
Conclusion: In subacute stroke patients, the response rates of 10mWT gait speed and 6MWT total distance (greater than 1.0) were high, showing a very strong correla tion before treatment. This indicates that both assessments measure similar aspects of walking ability. The tasks and components of the TUG, 5Times STS, BBS include move ments and activities that can influence the walking speed and distance measured by the 10mWT and 6MWT, demon strating moderate concurrent validity. The 10mWT gait speed explained 87% of the variance in the 6MWT total distance, validating its predictive power. Unlike the 6MWT, the 10mWT does not require long corridors or controlled environments, allowing for rapid assessment of walking ability. Therefore, it is useful for repeated measurements or initial diagnosis and can serve as a supplementary method to indirectly estimate the 6MWT total distance.
