Wearing smart glasses may be distracting and thus annihilate the beneficial effects of cues on freezing of gait in Parkinson’s disease. Furthermore, augmented reality cues might be effective in reducing FOG specifically in cueing-responsive patients. We present a single-patient study in which a patient with Parkinson’s disease traversed a doorway under different cueing conditions. Wearing augmented reality (AR) glasses did not deteriorate FOG nor affect the beneficial effects of cues. The AR visual cues did not improve FOG. This single-patient study implies that the current design of AR glasses does not stand in the way of the development of augmented reality visual cues. However, the effectivity of augmented reality visual cues remains to be proven.

佩戴增强现实眼镜时，传统视觉提示的有益效果得以保留。

戴智能眼镜可能会分散注意力，从而消除线索对帕金森氏病步态冻结的有益作用。此外，增强现实提示可能会特别在提示反应性患者中有效降低FOG。我们提出了一项单人研究，其中帕金森氏病患者在不同的提示条件下横过门道。戴增强现实（AR）眼镜不会使FOG恶化，也不会影响提示的有益效果。AR视觉提示不能改善FOG。这项单人研究表明，AR眼镜的当前设计并不妨碍增强现实视觉提示的发展。但是，增强现实视觉提示的有效性仍有待证明。
