  "abstract": "A 58-year-old man reported worsening balance and difficulty walking, with brief episodes of inability to move his feet forwards despite intending to walk. He had a 17-year history of Wilson’s disease, ATP7B homozygous pathogenic variant (c.51+4A>T—intronic). On examination, he had akinetic symmetrical parkinsonism but no cerebellar signs. We interpreted his walking difficulty as freezing of gait (online supplemental video—first segment), but unfortunately, it persisted despite a trial of levodopa.SP110.1136/pn-2025-004564.supp1Supplementary video",
