Freezing of gait (FOG) is a debilitating episodic gait disorder that significantly reduces the quality of life (QoL) in patients with Parkinson's disease (PD). Diagnosing and treating FOG remains a major medical challenge. This study aimed to assess the correlation between FOG and both motor and non-motor clinical characteristics in patients with PD.
In this retrospective cohort study, 112 patients with PD were divided into two groups using the New Freezing of Gait Questionnaire (NFOG-Q): one group with FOG (PD-FOG, 53 patients) and one group without FOG (PD-nFOG, 59 patients). The severity of PD and FOG was assessed using the Unified Parkinson's Disease Rating Scale (UPDRS), the Hoehn-Yahr (H-Y) staging system, and the NFOG-Q. The study also analyzed non-motor symptoms, including sleep disturbances, cognitive impairments, depression, anxiety, apathy, fatigue, and QoL.
The prevalence of FOG was 47.3%. The PD-FOG group exhibited a longer duration of PD (P = 0.002), a higher H-Y stage indicating PD progression (P = 0.003), and elevated anxiety levels (P = 0.003) compared to the PD-nFOG group. According to binary logistic regression analysis, the higher H-Y stage (P = 0.022), anxiety level (P = 0.005), UPDRS part II (P = 0.001), and part III (P = 0.008) were significant predictors for the occurrence of FOG.
Patients with Parkinson's disease who have a higher Hoehn-Yahr (H-Y) stage, higher UPDRS score, and elevated levels of anxiety are more likely to experience FOG.
冻结步态（FOG）是一种使人虚弱的间歇性步态障碍，会显著降低帕金森病（PD）患者的生活质量（QoL）。诊断和治疗 FOG 仍然是一个主要的医学挑战。本研究旨在评估 FOG 与 PD 患者的运动和非运动临床特征之间的相关性。
在这项回顾性队列研究中，112 名 PD 患者使用新冻结步态问卷（NFOG-Q）分为两组：一组有 FOG（PD-FOG，53 名患者），一组无 FOG（PD-nFOG，59 名患者）。使用统一帕金森病评定量表（UPDRS）、Hoehn-Yahr（H-Y）分期系统和 NFOG-Q 评估 PD 和 FOG 的严重程度。该研究还分析了非运动症状，包括睡眠障碍、认知障碍、抑郁、焦虑、冷漠、疲劳和生活质量。
FOG 的患病率为 47.3%。与 PD-nFOG 组相比，PD-FOG 组的 PD 持续时间更长（P=0.002），PD 进展的 H-Y 分期更高（P=0.003），焦虑水平更高（P=0.003）。根据二元逻辑回归分析，更高的 H-Y 分期（P=0.022）、焦虑水平（P=0.005）、UPDRS 第二部分（P=0.001）和第三部分（P=0.008）是发生 FOG 的显著预测因素。
H-Y 分期更高（P=0.022）、UPDRS 评分更高（P=0.001）和焦虑水平升高（P=0.008）的帕金森病患者更有可能出现 FOG。
