The fluctuation ratio with delay unit d 1 = 5 samples and d 2 = 20 samples in relation (1) of the training group, 32 PD (star) and 20 ET (circle) subjects. The fluctuation ratio is a log scale of percentage of temporal fluctuation while performing resting task to kinetic task of an individual subject. The log scale is used because the distribution of percentage of temporal fluctuation while performing resting task to kinetic task is skew
