Motor score was the MDS-Unified Parkinson’s Disease Rating Scale-III OFF/ON medication for Parkinson's disease, Toronto Western Spasmodic Torticollis Rating for cervical dystonia, and Burke-Fahn-Marsden Dystonia Rating Scale (movement) for oromandibular dystonia.
RBDSS score was obtained by visual inspection of movement and vocalisation behaviours during REM sleep (see the Materials and methods section).
RSWA was the percentage of time of REM sleep without atonia among all REM sleep time. C, cervical dystonia; Dx, disease duration; Dyst, dystonia; M, Meige syndrome (oromandibular dystonia); NA, not applicable; PD, Parkinson’s disease; PSQI, Pittsburgh Sleep Quality Index; RBDSQ, REM Sleep Behaviour Disorder-Screening Questionnaire; RBDSS, REM Sleep Behaviour Disorder-Severity Scale; RSWA, REM sleep without atonia.
