ABSTRACT
Objective o investigate the clinical characteristics and relevant risk factors of freezing gait in patients with Parkinson's disease (PD).Methods A total of 570 consecutive PD patients were registered basic information and evaluated by Unified Parkinson's Disease Rating Scale (UPDRS) and New Freezing of gait questionnaire (NFOG-Q).They were divided into the PD with freezing gait group (188 cases) and non-freezing gait group.Results UPDRS score in each part (UPDRS-Ⅰ,UPDRS-Ⅱ,UPDRS-Ⅲ,UPDRS-Ⅳ) and Hoehn & Yahr stage of the PD freezing gait group was significantly higher than that of the non frozen gait group (P ＜ 0.05).Conclusions PD patients with frozen gait group experience more rapid PD progression than those without freezing of gait.The appearance of FOG is associated with the mental behavior and emotion,treatment complication,disease severity,and course of PD.
