Abstract
Objectives
This study aims to objectively evaluate turning gait parameters in Parkinson disease (PD) patients using 2D-RGB video-based analysis and explore their relationships with imbalance.
Methods
We prospectively enrolled PD patients for clinical assessments, balance analysis and gait with 180’ turning. Spatiotemporal gait parameters during turning were derived based on 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, higher number of steps, wider step bases and showed less variability in step length during turns. COP oscillations were positively correlated with mean turning time in the both anterio-posterior (AP) and right-left (RL) axis.
Conclusions
Spatiotemporal gait parameters during turning, derived from video-based gait analysis, may be a promising biomarker for monitoring postural instability in PD patients.
