The principal motor features of Parkinson's disease (PD) include rigidity, tremor, bradykinesia, and postural instability. These motor deficits might cause gait dysfunction including reduced gait velocity, stride length, arm swing, and increased gait variability. Among these, increase in gait variability increased fall risk and served as a marker of disease progression. Previous studies reported that some factors might influence gait variability. However, which one contributes most has not yet been verified. Therefore, the purpose of the present study is to identify the more related influencing factors on gait variability in people with PD.
