# Adjusted for disease duration. MMSE—Mini-Mental State Examination; FAB—Frontal Assessment Battery; PPA—Physiological Profile Assessment; TUG—Timed up and go test. Note: higher scores indicate better performances in the MMSE, FAB, contrast sensitivity, quadriceps strength, step velocity and worse performances in the proprioception, hand reaction time, postural sway, PPA, coordinated stability, step time variability and TUG.
