This study tested how muscle strength is associated with functional walking capacity using the six-minute walk test (6MWT). We evaluated 63 patients with stroke using five muscle-strength indexes. This study demonstrated a large difference in the percentage of muscle weakness in patients' affected sides compared with the less affected sides. Muscle strength contributes to the variability in the 6MWT, supporting the need for task-specific training to increase walking distance and muscle-strength training in different positions for patients with stroke. The indexes assess muscle strength in multiple muscles, determining the relationship between all lower-limb muscles and the contribution of each muscle to walking.
