Objective
To evaluate the association between self-selected walking speed (Sfree), oxygen consumption at Sfree (Vo2free), the oxygen cost of walking (Cw) at Sfree, and mobility independence and independence for activities of daily living in individuals poststroke. Design Cross-sectional study. Setting Hospital. Participants Individuals with stroke who were able to walk without human assistance were included. We included 90 individuals (N=90; mean age, 63.5±14.0y). Interventions Not applicable. Main Outcome Measures Cw was captured during walking from measurements of Sfree and Vo2free. We assessed mobility independence based on the modified Functional Ambulation Classification (mFAC) and independence in activities of daily living by the Barthel Index (BI). Multiple linear regression analyses were performed to evaluate the independence of Cw, Vo2free, and Sfree from the determination of BI and mFAC among the various characteristics of the population (age, stroke delay, body mass index, motor function, spasticity). Results We reported Cw=0.36 mL/kg/m (interquartile range [IQR]=0.28 mL/kg/m), Sfree=0.60±0.32 m/s, Vo2free=11.2 mL/kg/min (IQR=1.8 mL/kg/min). The multiple linear regression analyses showed that Cw and Sfree were independently associated with the BI (P<.01 and the mfac scores. vo2free was not found to be an explanatory variable of functional independence>.05). Conclusions Cw was independently associated with functional independence. This association appears to be primarily determined by Sfree and not Vo2free, underscoring the importance of evaluating and acting on Sfree to improve the functional independence of individuals with stroke. |
