Elderly controls (EC), participants with Parkinson’s disease that do not show freezing of gait (PD-FoG), participants with Parkinson’s disease that usually have FoG but did not show it during the experiment (PD+FoG−), and participants with Parkinson’s disease and FoG during the experiment (PD+FoG+). Gender f/m female/male, BMI body mass index (in kg/m2), MoCA Montreal Cognitive Assessment71, UPDRS Unified Parkinson’s Disease Rating Scale72. Reported are means and standard deviations; the differences between the groups are not significant, except for gender, and LEDD between PD-FoG and PD+FoG+. We note that LEDD was not available for all subjects.
