Abstract
Background: Measurements of cardiorespiratory fitness are mandatory after a stroke. The 6-min step test emerges as an alternative method in absence of maximal tests.
Objective: To provide information regarding the measurement properties of the 6-min step test in individuals with chronic stroke.
Methods: A cross-sectional, methodological study was conducted. Participants were individuals with stroke, who performed the 6-min step test and the 6-min walk test for calculation of measurement properties and comparison purposes. Outcomes of interest were test-retest and inter-rater reliability, measurement error, minimal detectable change, construct validity, criterion validity by video, intra-rater and inter-rater reliability by video.
Results: Fifty individuals with chronic stroke were included. The 6-min step test had a very-high test-retest (ICC 0.98; CI 95% 0.97-0.99) and inter-rater reliability (ICC 0.95; CI 95% 0.92-0.97). The test's measurement error was 4(5%) and the minimal detectable change was 11 repetitions. The correlation between the 6-min step test and the 6-min walk test suggested high construct validity (r = 0.79; CI 0.66-0.89). In addition, the 6-min step test by video had comparable results with the in-person administration with very high criterion validity (r = 1.00; CI 95% 1.00-1.00),intra-rater (ICC = 1.00; CI 95% 1.00-1.00) and inter-rater reliability (ICC = 1.00; CI 95% 1.00-1.00).
Conclusion: The 6-min step test has appropriate measurement properties to estimate cardiorespiratory fitness in individuals with chronic stroke. Moreover, the video administration of the 6-min step test produced comparable results with the in-person administration.
期刊介绍:
Topics in Stroke Rehabilitation is the leading journal devoted to the study and dissemination of interdisciplinary, evidence-based, clinical information related to stroke rehabilitation. The journal’s scope covers physical medicine and rehabilitation, neurology, neurorehabilitation, neural engineering and therapeutics, neuropsychology and cognition, optimization of the rehabilitation system, robotics and biomechanics, pain management, nursing, physical therapy, cardiopulmonary fitness, mobility, occupational therapy, speech pathology and communication. There is a particular focus on stroke recovery, improving rehabilitation outcomes, quality of life, activities of daily living, motor control, family and care givers, and community issues.
The journal reviews and reports clinical practices, clinical trials, state-of-the-art concepts, and new developments in stroke research and patient care. Both primary research papers, reviews of existing literature, and invited editorials, are included. Sharply-focused, single-issue topics, and the latest in clinical research, provide in-depth knowledge.
