Change of gait parameters induced by the designed carpets in PD patients with and without executive dysfunction. A Stride length. B Gait speed. C Fall risk. n = 24 for PD patients with executive dysfunction; n = 41 for PD patients without executive dysfunction. Values are expressed as means ± SE for stride length and gait speed. Data of fall risk is expressed as median and interquartile range. *P < 0.05; **P < 0.01; ***P < 0.001
