Abstract:
Objective:To analyze the gait characteristics of freezing of gait (FOG) in patients with Parkinson's disease (PD).Methods:One hundred and four patients with PD, admitted to our hospital from January 2019 to November 2020, were enrolled in our study. Based on whether patients were accompanied by FOG or not, these patients were divided into PD with FOG group ( n=46) and PD without FOG group ( n=58). "JiBuEn" gait analysis system was used in gait data collection. The gait performance of patients from PD with FOG group was analyzed from 4 perspectives, spatiotemporal parameters, kinematic parameters, and variability and symmetry analyses of gait parameters. Results:As compared with PD without FOG group, PD with FOG group demonstrated a decrease in stride length and gait velocity, an increase in stride length variability, stride time variability, stance-phase time variability and swing phase time variability, with significant differences ( P<0.05). In addition, the heel-strike angle, toe-off angle, range of motion of ankle joint, range of motion of knee joint and range of motion of hip joint in PD with FOG group were significantly decreased as compared with those in PD without FOG group ( P<0.05). Stride length asymmetry index in PD with FOG group was significantly increased as compared with that in the PD without FOG group ( P<0.05). Conclusion:PD patients with FOG mainly exhibit shorter stride length, slower gait velocity, more variable gait pattern and more significant impairment in kinematic parameters than those without FOG.
