BACKGROUND: Previous studies reported a preserved ability to cycle in freezers, creating opportunities for restoring mobility and independence. However, use of a bicycle is not always feasible. Here, we investigated the effectiveness of a "walk-bicycle" in reducing freezing of gait (FOG). METHODS: Eighteen Parkinson patients with FOG performed the following tasks, each four times, with and without the walk-bicycle: (1) normal walking; (2) walking with small steps, at normal speed; (3) walking with small steps, as rapidly as possible. RESULTS: Seven patients showed FOG during walking without the walk-bicycle. In those patients, the walk-bicycle afforded a 12% reduction of time frozen (p = 0.026). In 11 patients no FOG was observed during walking without the walk-bicycle. Two of them showed FOG when using the walk-bicycle. CONCLUSIONS: The walk-bicycle may help to reduce FOG in some patients, but not in all. Future studies need to evaluate its usefulness in a home environment.
