|mdc312031-sup-0001-VideoS1.mp4||MPEG-4 video||34105K||Video 1. Segment A and segment B show cases 1 and 2, respectively, with rest tremor resembling PD. The gait pattern however is clearly incongruent and bizarre: in case 1 with truncal flexion and extension, and exaggerated uplifting of the affected leg; in case 2 being trepidant and with knee buckling (walking on ice) but without true imbalance.|
|mdc312031-sup-0002-VideoS2.mp4||MPEG-4 video||23116K||Video 2. Segment A shows a 56-year-old woman (case 3) with a psychogenic movement disorder resembling right-sided hemichorea. When performing tasks with her left hand, the movements on the right cease. Her gait is excessively slow and cautious wiith a tendency to hold on to the wall. She tends to limp and has marked swaying without actual loss of balance. Segment B shows a 32-year-old woman (case 4) with jerky trunk movements which could be interpreted as propiospinal myoclonus. On walking she displays a somewhat bizarre looking, highly uneconomical gait.|
|mdc312031-sup-0003-VideoS3.mp4||MPEG-4 video||30996K||Video 3. Segment A shows case 5 with a dystonic sort of symptoms, i.e. grimacing, mouth opening and side-to-side head tremor, which are considered unusual for typical cranio-cervial dystonia. His gait is trepidant, jerky and staggering, and therefore clearly incongruent to adult-onset dystonia. Segment B shows case 6 with jerky and choreiform leg movements and no clear entrainment. Symptoms seem to abate when getting dressed, and gait is of bizarre appearance and greatly uneconomical.|
