Electronic supplementary material
Below is the link to the electronic supplementary material.
Video 1: A 60-year-old man with Parkinson’s disease and severely disabling freezing of gait. (MP4 3751 kb)
Video 2: The same patient demonstrating a preserved ability to climb stairs. (MP4 5639 kb)
Video 3: Demonstration of a painted three-dimensional staircase illusion alleviating freezing of gait. (MP4 9916 kb)
All three videos were videotaped after each other (video 1–2–3), when levodopa had worn off and the patient experienced an OFF-phase.
