Assessing stroke recovery: How well do walk tests measure progress? This study evaluates the relationship between functional walk tests, exertion levels, and impairments in individuals recovering from stroke. The research explores the correlation between the 6-Minute Walk Test (6MWT) and 12-Minute Walk Test (12MWT) and measures of exertion (perceived and myocardial), and impairment. In addition, the relationship between the 6MWT, 12MWT, and self-paced gait speed were also evaluated. Key results indicated that heart rate reached a steady state after 6 minutes, reflecting moderate exercise intensity. The 6MWT, 12MWT, and self-paced gait speed were all highly correlated with one another and were all related to the severity of impairments. The functional walk distances did not relate either to perceived exertion or actual exertion. Overall, the study suggests that stroke-specific impairments, rather than exertion levels, are the primary limitations to walking distance in stroke patients. The authors recommend measuring both exertion and distance when using functional walk tests to assess performance over time.
As a study published in Stroke, this research aligns with the journal's focus on neurological rehabilitation and stroke outcomes. By examining the validity and utility of functional walk tests, the paper contributes to improved assessment methods for stroke patients. The findings offer practical guidance for clinicians involved in stroke rehabilitation.
