[Purpose] To investigate how different ankle-foot orthosis functions with the same dorsiflexed setting of initial ankle joint angle affect the walking ability in individuals with chronic stroke. [Participants and Methods] In this randomized crossover study, participants underwent a 10-m walking test and walked on a WalkWay MW-1000 three times under these conditions: (1) without ankle-foot orthosis; (2) with ankle-foot orthosis with an adjustable posterior strut at 5° of fixed dorsiflexion; and (3) with ankle-foot orthosis with an adjustable posterior strut at 5–20° of restricted dorsiflexion. The primary outcome was walking speed on the 10-m walking test. The secondary outcomes were walking speed and spatiotemporal factors measured by the WalkWay MW-1000. [Results] Fifteen individuals (mean [standard deviation] age, 60.9 [8.6] years; male, 12) were enrolled. Walking speeds of the ankle-foot orthosis with fixed and restricted dorsiflexion groups were significantly higher than those without the orthosis; however, no outcomes differed significantly between ankle-foot orthosis with fixed versus restricted dorsiflexion groups. [Conclusion] In individuals with chronic stroke, ankle-foot orthosis function may be less important than the dorsiflexed setting of initial ankle joint angle in the ankle-foot orthosis.
