Abstract
Objective: This study aims to objectively evaluate turning gait parameters in Parkinson's disease (PD) patients using 2D-RGB video-based analysis and explore their relationships with imbalance.
Methods: We prospectively enrolled PD patients for clinical assessment, balance analysis and gait with 180º turning. Spatiotemporal gait parameters during turning were derived using video-based analysis and correlated with modified Hoehn and Yahr (mHY) stages and center of pressure (COP) oscillations.
Results: A total of 64 PD patients were enrolled. The PD patients with higher mHY stages (≥2.5) had significantly longer turning times, greater numbers of steps, wider step bases and less variability in step length during turns. COP oscillations were positively correlated with the mean turning time on both the anterior-posterior and right-left axes.
Conclusion: Spatiotemporal gait parameter during turning, derived from video-based gait analysis, may represent apromising biomarker for monitoring postural instability in PD patients.
目的:采用基于2D-RGB视频的分析方法,客观评价帕金森病(PD)患者的转身步态参数,并探讨其与失衡的关系。方法:前瞻性招募PD患者进行临床评估、平衡分析和180度转弯步态。基于视频分析,导出了转弯时的时空步态参数,并与改进的Hoehn and Yahr (mHY)阶段和压力中心(COP)振荡相关联。结果:共入组64例PD患者。mHY分期越高(≥2.5)的PD患者,转弯时间越长,步数越多,步基越宽,转弯时步长变异性越小。COP振荡与前后轴(AP)和左右轴(RL)平均转弯时间呈正相关。结论:基于视频的步态分析得出的转弯时的时空步态参数可能是监测PD患者姿势不稳定的有希望的生物标志物。
