Objective To preliminarily summarize the epidemiological and clinical characteristics of functional movement disorder (FMD) based on movement disorders clinic in China. Methods and Results A total of 593 patients with movement disorders newly diagnosed in movement disorders clinic of 22 clinical medical centers from August to September in 2023 were included, including 37 patients (6.24%) with FMD and 556 patients (93.76%) with organic movement disorder. Comparison of the epidemiological characteristics of the 2 groups, the proportions of corona virus disease (COVID-19) infection (χ² = 4.217, P = 0.040) and psychopsychological symptoms (χ² = 18.694, P = 0.000) in the FMD group were higher than those in the organic movement disorder group, while age (t = 3.757, P = 0.000), age of onset (t = 3.720, P = 0.000) and proportion of hypertension (χ² = 4.736, P = 0.030) were lower than those in the organic movement disorder group. Comparison of the clinical characteristics of the 2 groups, the FMD group had higher proportions of tremor (χ² = 3.955, P = 0.047) and myoclonus (Fisher's exact probability: P = 0.011) than the organic movement disorder group, and the proportions of parkinsonism (χ² = 8.491, P = 0.004) and gait disorder (χ² = 5.028, P = 0.025) were lower than those in the organic movement disorder group. Conclusions The age and age of onset, as well as the proportions of COVID-19 infection, hypertension, psychopsychological symptoms, tremor, myoclonus, parkinsonism and gait disorder with FMD were different from those with organic movement disorder in China.
