A risk of future falls was suggested to be related to slow gait with freezing (SGF) elicited by a fear of falling before arrival at a narrowed entrance or while walking on a narrow path, as well as to the Unified Parkinson’s Disease Rating Scale part II score, associated with SGF. In the same study, we had faller patients walk on a path that narrowed in a straight-line fashion to determine whether SGF could be improved. In one patient, who showed a unique paradoxical gait, SGF resolved. We describe this patient in the hope that our experience will provide potential clues to effective ways to prevent future falls in patients with Hoehn-Yahr stage III PD. To prevent gait instability elicited by fear of falling in patients with Hoehn-Yahr stage III PD, it might be useful to remove narrowed entrances.
