Gait cycle parameters of PD+FOG group and PD-FOG group.

T-T test and Mann-Whitney U test were utilized for comparing the gait cycle parameters between two disease groups. Compared to PD-FOG group, PD+FOG group displayed a decreased walking speed (p = 0.006), smaller stride length (p = 0.004), smaller step length (p = 0.001) and prolonged double support time (p = 0.022).Abbreviation: PD+FOG = PD patients with freezing of gait; PD-FOG = PD patients without freezing of gait.采用T检验（T-T test）与曼-惠特尼U检验（Mann-Whitney U test）对两组疾病组的步态周期参数进行比较。 与不伴步态冻结（freezing of gait, FOG）的帕金森病（Parkinson's Disease, PD）患者组（PD-FOG）相比，伴步态冻结的帕金森病患者组（PD+FOG）表现为行走速度减慢（p=0.006）、步幅减小（p=0.004）、单步步长缩短（p=0.001）且双支撑时间延长（p=0.022）。 缩写说明：PD+FOG指伴步态冻结的帕金森病患者；PD-FOG指不伴步态冻结的帕金森病患者。
