Parkinson's disease (PD) is an idiopathic disease of the nervous system characterized clinically by parkinsonism: chronic progressive tremor, bradykinesia, rigidity, and postural instability. The major pathologic feature of PD is the profound loss of pigmented neurons, mainly in the pars compacta of the substantia nigra (SN).
Overall, the visual flow of texture motion generated from the low and high forward velocities induced greater postural instability as compared with the zero forward velocity conditions of roll trials (Figures 4-6).
Our findings regarding identification of postural instability based on SOT results in persons with PD compared to healthy individuals are consistent with previous research [7,37,41].
Although postural instability may have multifactorial causes, it primarily results from impaired central integration [3, 31].
