The purpose of this study was to research the effect of an ankle foot orthosis (AFO)-shaped elastic band on gait over obstacles in stroke patients. This study was conducted on 10 patients with stroke to be recruited voluntarily. They were performed to walk from 1m before to 1m after GAITRite System. They were compared with and without the AFO-shaped elastic band in temporal and spatial aspects of 5cm obstacle. Participants wearing the AFO-shaped elastic band was significantly increased cadence and decreased step length differential between affected and less-affected sides compared to them without it. The heel to heel (H-H) base support was significantly increased in the less-affected side with the AFO-shaped elastic band compared to them without it. We suggest that the AFO-shaped elastic band was contributed to gait over obstacles in safe and improve the asymmetry between the affected and less-affected sides. However, it needs to be further studies of kinematic data and muscle activation in gait over obstacles using the AFO-shaped elastic band.
