Relationships between self-reported and performance-based measures of functional capacity in individuals with chronic stroke

Abstract

[Purpose] The aim of this study was to investigate the associations between self-reported and valid performance-based measures of functional capacity in individuals with chronic stroke. [Subjects and Methods] Self-reported measures of functional capacity of 31 individuals with chronic stroke were assessed by the Duke Activity Status Index scores, whereas performance-based measures were assessed by the distance covered (in meters) and oxygen consumption (relative oxygen consumption, in ml·kg−1·min−1) during the six-minute walking test. [Results] The subjects had a mean age of 58.6±13 years and a mean time since the onset of stroke of 28.3±15.1 months. They had a mean Duke Activity Status Index of 27.3±14.4, mean distance covered of 325.2±140.2 m, and mean relative oxygen consumption of 9.6±2.3 ml·kg−1·min−1. Significant, positive, and moderate to good correlation coefficients were found between the Duke Activity Status Index scores and the distance covered during the six-minute walking test (r=0.68). Significant, positive, and fair associations were also found between the Duke Activity Status Index scores and relative oxygen consumption values obtained during the six-minute walking test (r=0.45). [Conclusion] The findings of the present study support the clinical use of the Duke Activity Status Index as a tool to assist in clinical evaluations of functional capacity of individuals with chronic stroke.

Effects of proprioceptive sense-based Kinesio taping on walking imbalance

“…In most cases, the walking function of patients is reported to be affected by neurological impairment, and this is apparently what induces problems with asymmetrical gait. Hence, recovery of walking function following stroke should be one of the main goals of rehabilitation10 ) .…”

Functional capacity of patients with chronic stroke based upon their physical activity levels

“…The results of this study answered the main question, since it was found that the individuals with stroke with higher levels of physical activity demonstrated higher functional capacity, i.e., present higher METS energy cost (in METS). Recently, the study of Polese et al [11] was the first to use the DASI for the assessment the functional capacity of a sample of 31 chronic stroke individuals, and found a mean DASI score of 27.3. This value was similar to that observed in the present study for the moderately active group, who showed a mean DASI score of 32.0 (SD 11.5).…”

“…Since functional capacity is related to physiological variables, i.e., oxygen consumption, the use of simple and reliable measures is crucial within clinical environments. Although the Duke Activity Status Index (DASI) was originally developed for the evaluation of patients with cardiovascular diseases [10], it has also been used with stroke individuals, since its scores were shown to be highly related to physical performance measures [11].…”
